Salesforce Development-Lifecycle-and-Deployment-Architect Salesforce Certified Development Lifecycle and Deployment Architect (WI25) Exam Practice Test

The product team should review the Checkmarx errors and determine if they need to fix them or not. If the errors are false positives, meaning that they do not indicate a real security issue, the product team should mark them as such and attach an explanation, then submit the security review. This will help the Salesforce security review team to understand the rationale behind the code and avoid unnecessary rejections. The product team should not leave the errors to the Salesforce security review team, as they may reject the request if they find any potential security issue. The product team should not leave a partner support case, as this is not the proper channel for resolving code issues. The product team should not fix all the errors before submitting the security review, as some of them may not be relevant or critical, and fixing them may introduce new bugs or delays.

D is the correct answer, as automated testing is the best approach to mitigate the risk of bugs being inadvertently introduced to production. Automated testing can help to ensure that the code meets the quality and functionality standards, as well as detect and prevent any errors or regressions before deploying to production. A is incorrect, as user acceptance testing is not enough to mitigate the risk of bugs, as it depends on the manual testing and feedback of the end users, which can be subjective and incomplete. B is incorrect, as the use of an agile methodology is not directly related to mitigating the risk of bugs, as it is a way of managing the project scope, requirements, and delivery. C is incorrect, as requirements traceability is not directly related to mitigating the risk of bugs, as it is a way of tracking the requirements and their fulfillment. You can learn more about this topic in the Testing Strategies module on Trailhead.

 In the post refresh plan, modifying external ids to a known valid set of values for UAT is the best way to resolve the issue of objects that have external ids from production no longer pointing to valid external ids in the UAT environment. This way, the data integrity and consistency across the integrated systems can be maintained. Letting UAT point to production integrations and rolling back each transaction after it finishes is not a good practice, as it can cause data loss or corruption in production. Deleting all the data and using an automated testing tool to create new data across all the systems in UAT is not feasible, as it can take a lot of time and resources. Masking the external id so nobody can see the production value is not a solution, as it does not address the underlying problem of invalid references.

 In the Metadata API, the External Object metadata type represents external objects. In the Metadata API, the Custom Object metadata type represents external objects.

The development model that is optimized for this need is to use unlocked packages to deploy the global code and allow each country to create its customized unlocked package extensions. This model can help maintain the global standardization and consistency of the code, while also providing the flexibility and autonomy for each region to customize some aspects of the code for their specific needs. Unlocked packages are a type of second-generation packaging that can be created and installed using the Salesforce CLI or APIs, and can be upgraded or uninstalled as needed. Unlocked package extensions are a type of unlocked packages that can depend on and extend another unlocked package or a managed package. See Unlocked Packages for more details.

 Using a Change Set or manually replicating the changes in the developer sandbox are both valid approaches to ensure that changes made in production are reflected in the sandbox that the developers are working on. Refreshing the developer sandbox would overwrite any changes made by the developers, and Salesforce-to-Salesforce is not a deployment tool.

The optimized order to load the objects is: accounts, contacts, leads, products, opportunities, opportunity line items. This order follows the dependency and relationship rules among the objects, such as: accounts must be loaded before contacts, as contacts are related to accounts; leads must be loaded before opportunities, as opportunities can be converted from leads; products must be loaded before opportunity line items, as opportunity line items are related to products; and opportunities must be loaded before opportunity line items, as opportunity line items are related to opportunities. See [Data Import Order] for more details.

This is the correct answer because Salesforce prohibits stress testing against production because it is a shared environment that hosts multiple customers and tenants. Stress testing against production may affect the performance and availability of the Salesforce service for other customers and violate the terms of service. Stress testing should be done in a sandbox or a developer edition org that is isolated from production.

 D is the correct answer, as the Agile methodology is the best way to handle a project with a fixed deadline and a changing scope, such as retiring a business-critical application that will no longer be supported. The Agile methodology allows for frequent feedback, iterative development, and adaptive planning, which can help to deliver a working solution on time and within budget. A is incorrect, as executive leadership is not a methodology, but a role that can support the project. B is incorrect, as a requirements traceability matrix is a tool that can help to track the requirements and their fulfillment, but not a methodology. C is incorrect, as a business continuity plan is a document that outlines how to resume business operations in the event of a disruption, but not a methodology. You can learn more about the Agile methodology in the Agile Basics module on Trailhead.

Tracking effort estimates, actuals, and remaining work can help the developer improve their estimation skills and accuracy, which can benefit the project planning and delivery.

The architect should recommend generating mock data that mimics production data shape and volume, and performing data masking on full sandbox after a refresh. These options allow the team to create realistic data sets for testing without violating the regulations that prohibit the use of production data in non-production environments. Requesting a partial sandbox copy after the next Salesforce release is not a valid option, as partial sandboxes are refreshed on demand and not tied to Salesforce releases. Using Query Analyzer in production is not a way to perform data volume testing, as it only analyzes the performance of SOQL queries.

The best solution to address the problem of user testing taking a long time due to data setup is to include automated sample data during deployment. This way, the users can have realistic and consistent data to test the functionality and performance of the system. Assigning more users to create test data, testing data creation being outside the scope of continuous integration, or training business users to create test data more efficiently are not effective solutions, as they still require manual effort and may result in inconsistent or inaccurate data.

Change sets provide an easy way to deploy related components, as they allow the user to select the components from a list and add them to the change set. They also provide a simple and declarative method for deployment, as they do not require any coding or scripting. Change sets do not provide the ability to deploy a very large number of components easily, as they have a limit of 10,000 components per change set. They also do not provide the ability to track changes to components, as they do not have any version control or history features.

The partner can use Developer Edition or Partner Developer Edition for development of the managed package. These environments allow the creation of a namespace and the packaging of components into a managed package. Developer sandbox and Developer Pro sandbox do not support these features and are not suitable for developing a managed package.

The best way to migrate from a managed package to an unlocked package is to split the components into two packages: one for the objects and fields, and one for the classes, Visualforce, and other components. This way, the data and integrations with the objects and fields of the managed package are preserved, and the classes and Visualforce can be modified and deployed using CI/CD processes with the unlocked package. Exporting and restoring the data from the managed package is not a feasible solution, as it would require a lot of effort and risk data loss or corruption. Installing the unlocked package with the same namespace as the managed package is not possible, as namespaces are unique and cannot be reused. Staying with the managed package is not a good option, as it does not allow for better integration with CI/CD processes.

Deploying unsupported components manually before/after deployment is the best way to address the issue of Metadata API not supporting all the components yet. Metadata API is a powerful tool for deploying changes between orgs, but it does not cover all the metadata types that are available in Salesforce. Some examples of unsupported components are email templates, dashboards, reports, and custom settings. These components need to be deployed manually by using other tools or methods, such as change sets, data loader, or manual configuration.

These are the correct answers because they are related to the data quality and integrity of the migrated data. Case association, case ownership, and data transformation are all important aspects of data migration that should be tested. Case assignment rules and escalation rules are not directly related to data migration, but rather to the business logic and workflow of the application. Page layout assignment is also not related to data migration, but rather to the user interface and security of the application.

Load testing is the type of testing that will help UC measure the page response time. Load testing simulates the expected number of concurrent users and measures how the system performs under normal load conditions. Unit testing, system integration testing, and stress testing are not designed to measure the page response time.

The best option for the new BU is to use a new stand-alone Salesforce org, not integrated with the others. This will allow the new BU to have flexibility in their business processes, without affecting or being affected by the other BUs. Since the new BU does not share customers with the other BUs, there is no need to integrate with the customer 360-degree view org, which would add complexity and cost. Deploying the new BU in the customer 360-degree view org is not a good idea, as it would create confusion and duplication of data, as well as limit the customization options for the new BU. Using the same Salesforce org of another BU that shares geographical localization with the new BU is also not a good idea, as it would create conflicts and dependencies between the two BUs, as well as reduce the performance and security of the org. Using a new Salesforce org for the new BU, and customizing integration so that it reads and writes customer information from the customer data org is unnecessary and inefficient, as the new BU does not need to access or update the customer data of the other BUs.

C and D are the correct answers, as they are the best strategies to address a critical production issue occurring in the middle of development. C is correct, as using a source control system to allow separate branches for current development and production bug fixes can help to isolate the changes and avoid conflicts or overwriting. D is correct, as refreshing a sandbox for replication of the issue and testing the use-case scenarios once the code is fixed can help to ensure the quality and functionality of the solution before deploying it to production. A is incorrect, as creating separate branches for current development and production bug fixes and deploying the fix with current development when ready can delay the resolution of the production issue and introduce new risks or errors. B is incorrect, as utilizing one branch for both development and production bug fixes to avoid out-of-sync branches and simplify deployment can create confusion and complexity in the code and make it harder to test and validate. You can learn more about these strategies in the Application Lifecycle and Deployment module on Trailhead.

 Identifying the relevant data and verifying the data integrity can help ensure the quality and accuracy of the migrated data. Using a full sandbox and performing test runs with real data can help validate the migration process and identify any issues or risks.

 B and D are the correct answers, as Force.com IDE and Force.com Migration Tool are the deployment tools that will support the request of creating a new custom object to track Shipping Containers and making it available globally by all Salesforce instances and further maintained and modified regionally by local administrators. Force.com IDE and Force.com Migration Tool are both tools that use the Metadata API to retrieve and deploy metadata components, such as custom objects, from one org to another. They also allow for selective deployment, meaning that only the components that are needed can be deployed, without affecting the rest of the org. A is incorrect, as Tooling API is not a deployment tool, but an API that provides access to metadata and code, as well as customizing and automating the development process. C is incorrect, as Change sets are not a deployment tool that will support the request, as they are limited to deploying components between connected orgs, and do not allow for selective deployment or regional modifications. You can learn more about these tools in the Deploy Changes with the Force.com Migration Tool and Deploy Changes with the Force.com IDE units on Trailhead.

A Port management tool is a tool that can support a project involving a large distributed development and testing team, by providing features such as requirements management, defect tracking, collaboration, and reporting. A Port management tool can also integrate with other tools, such as code repositories, testing tools, and deployment tools, to provide a comprehensive view of the project status and progress. A Spreadsheet is not a suitable tool for managing requirements and defects, as it is prone to errors, duplication, and inconsistency. A Code Repository is a tool that stores and manages the source code of the system, but does not manage requirements and defects. Wave is a tool that provides analytics and insights on data, but does not manage requirements and defects.

 C and D are the correct answers, as Load Test and Performance Test are the test types that should be suggested to ensure that a large inbound call center does not experience platform slowdowns under high call volume for the Lead object. A load test is a test that measures the performance and behavior of the system under a specific load, such as a large number of concurrent users or requests. A performance test is a test that measures the speed, responsiveness, and stability of the system under various conditions, such as different configurations or environments. These tests can help to identify and prevent any potential issues or bottlenecks that could affect the user experience or the system functionality. A is incorrect, as Unit Test is not a test type that should be suggested for this scenario, as it is a test that verifies the functionality and logic of a single unit of code, such as a method or a class, but not the performance or behavior of the system as a whole. B is incorrect, as Stress Test is not a test type that should be suggested for this scenario, as it is a test that measures the performance and behavior of the system under extreme or abnormal conditions, such as exceeding the capacity or resources of the system, but not the performance or behavior of the system under normal or expected conditions. You can learn more about these tests in the Testing Strategies module on Trailhead.

To move to the package development model, the administrator must enable both the Dev Hub and the Second-Generation Managed Packages in setup. The Dev Hub is the main org where the administrator can create and manage scratch orgs and packages. The Second-Generation Managed Packages are the new format of packages that support modular development and versioning. The Unlocked Packages are a type of second-generation packages that are not tied to a namespace and can be installed and customized in any org. The Source Tracking for Scratch Orgs is a feature that allows the administrator to track the changes made in a scratch org and push or pull them to or from a source repository.

 Refreshing a Partial Copy sandbox every weekend and including an appropriate sandbox template will allow UC to train the users on samples of production data and delete all the data generated during the training session at the end of the week. Loading data using data loader is not necessary if the sandbox template includes the relevant data. Developer Pro sandboxes have limited storage and may not be able to accommodate the data needed for the training.

 Using a Source Control system alongside a multi-sandbox development strategy has several advantages, such as performing code reviews before promoting to a pre-production sandbox, keeping a history of changes made by each developer, and creating a branching strategy that tracks each feature or change separately. Automatically deploying changes from sandbox to production is not an advantage of Source Control, but rather a function of a Continuous Integration tool. Acting as a backup in case of catastrophic data loss is not an advantage of Source Control, but rather a benefit of having a sandbox strategy.

 Two options that should be considered when making production changes in a highly regulated and audited environment are: all changes including hotfixes should be reviewed against security principles, and any production change should have explicit stakeholder approval. These options can help ensure that the changes are compliant with the regulations and have the necessary authorization and documentation. No manual steps should be carried out is not a valid option, as some changes may require manual steps, such as data migration or post-deployment verification. After deployment, the development team should test and verify functionality in production is also not a valid option, as testing and verification should be done in a lower environment before deploying to production, and the responsibility of testing and verifying functionality in production should be assigned to a different team than the development team. See Application Lifecycle and Deployment for more details.

 B and D are the decisions that should be made by an Architecture Review Board (ARB), as they involve choosing the best methodology and authentication mechanism for the project, which have significant impacts on the project scope, quality, and security. A is not a decision that should be made by an ARB, as it is a low-level design decision that can be made by the developers or technical leads. C is not a decision that should be made by an ARB, as it is a testing decision that can be made by the testers or quality assurance leads.

QUESTIONNO: 87

What is the process used to initiate a connection for change sets?

A. Modify the source org to allow an outbound connection to the target org

B. Modify the target org to accept an outbound connection from the source org

C. Modify the target org to accept an inbound connection from the source org

D. Modify the source org to allow an inbound connection to the target org

Answer: A

A is the correct answer, as the process to initiate a connection for change sets is to modify the source org to allow an outbound connection to the target org. B and C are incorrect, as the target org does not need to accept any connection from the source org, but only to deploy the inbound change sets that are sent from the source org. D is incorrect, as the source org does not need to allow any inbound connection to the target org, but only to create and upload the outbound change sets to the target org. You can learn more about this process in the Change Sets Basics module on Trailhead.

 Creating a release calendar, training and aligning all the teams is the best way to avoid conflicts and ensure smooth releases between major, minor, and Salesforce seasonal releases. A release calendar can help the teams plan ahead, coordinate their efforts, and avoid overlapping or conflicting changes. Training and aligning the teams can help them understand the release processes, the best practices, and the expectations for each release type. Gating all release decisions at the center of excellence, sharing the test plans, or creating a spreadsheet of metadata changes are not sufficient or scalable solutions for this problem.

The architect should suggest the following actions to help UC discover the failing unit tests earlier: Train the administrators to make their changes in a special “admin changes” sandbox, and then promote to production, and ensure a metadata backup is committed to version control every day and a diff published to the release team. Training the administrators to use a sandbox can help prevent direct changes to production that can break the code or the unit tests. Ensuring a metadata backup and a diff can help identify any changes that have been made to production and compare them with the source of truth.

 Sandboxes should be refreshed based on the needs of the project and the development lifecycle. Production is the only pristine environment, so it is a good practice to refresh sandboxes from production regularly to ensure data and metadata consistency. Integration sandboxes should be refreshed frequently, not rarely, to avoid conflicts and errors when integrating code from multiple developers. Development environments should generally be refreshed after each working feature has been successfully migrated, to avoid accumulating unnecessary changes and to start fresh for the next feature.

The recommended mechanism for releasing the application that can be installed in the trading partners’ Salesforce environments is a managed package. A managed package is a collection of application components that can be distributed and installed in other orgs. Managed packages allow you to control the visibility and upgradability of the components, as well as provide namespace isolation and license management. Change sets are not suitable for releasing applications to other orgs, as they can only be used for orgs that are affiliated with the same production org. Unmanaged packages are not ideal for releasing applications that need to be updated frequently, as they do not allow you to push upgrades or control the components after installation. Zip file deployable by SFDX or ANT is not a user-friendly way of releasing applications, as it requires the users to have technical knowledge and tools to install the components.

Active Process Builders are configuration items that should be covered by executable tests, as they can have complex logic and actions that affect the behavior and performance of the application. Validation Rules, Workflow Rules, and Case Assignment Rules are also configuration items, but they are simpler and less likely to cause errors or conflicts. Therefore, they can be verified by manual testing or declarative tools.

The best deployment strategy for UC to use in this environment is to refresh the developer’s sandbox, develop changes, refresh the common sandbox, deploy to the common sandbox, test changes, as this will ensure that the developer’s sandbox has the latest production data and metadata, and that the common sandbox has the latest production data and metadata as well as the developer’s changes, before testing and deploying to production. Option B is not correct, as refreshing the developer’s sandbox after testing the changes will erase the changes and make them unavailable for deployment to the common sandbox. Option C is not correct, as refreshing the developer’s sandbox after developing the changes will erase the changes and make them unavailable for deployment to the common sandbox. Option D is not correct, as refreshing the common sandbox before developing the changes will make the common sandbox out of sync with the production data and metadata.

 REST API SObject Tree Request and REST API Composite Request are two ways to insert multiple related records in one call or transaction. REST API SObject Tree Request allows you to create nested records that share a root record. REST API Composite Request allows you to execute a series of REST API requests in a single call. Bulk API 2.0 and Streaming API are not suitable for inserting multiple related records in one call or transaction. Bulk API 2.0 is used for loading large batches of data asynchronously, and Streaming API is used for receiving notifications of data changes in real time.

Deploying metadata to production orgs using package development model is the best option for the multi-org deployment strategy, as it allows you to create modular and reusable packages that can be easily installed and updated across different orgs. Deploying metadata to production orgs using managed packages is not suitable for this scenario, as managed packages are typically used by ISVs to distribute their applications to customers, and they have some limitations and restrictions that may not fit the requirements of UC. Deploying metadata to production orgs using unmanaged packages is also not a good option, as unmanaged packages are mainly used for one-time distribution of components, and they do not support upgrades or dependencies. Deploying metadata to production orgs using change sets is not feasible for this scenario, as change sets can only be used to deploy metadata between connected orgs in the same Salesforce instance, and UC has separate orgs for each region. See [Package Development Model] for more details.

 A single org strategy has the benefits of increased ability to collaborate, centralized data location, and consistent processes across the business. These factors can improve efficiency, data quality, and user adoption. A single org strategy may not allow for tailored implementation or fewer inter-dependencies, as different business units may have different requirements and dependencies.

The evidence that can support the CTO’s claims is a burndown chart showing the team misses their forecast sprint after sprint. This indicates that the team is overcommitting and not able to deliver the work they planned. The definition of done, the Kanban board, and the burndown chart showing the team finishes early are not relevant to the CTO’s claims, as they do not reflect the actual progress and performance of the team.

 To address the bug in production, the architect should recommend the following approaches: Investigate potential data impacts, fix the bug in a hotfix branch, and seek stakeholder approval for the hotfix. Investigating the data impacts can help assess the severity and scope of the bug, and determine the best course of action to mitigate any data loss or corruption. Fixing the bug in a hotfix branch can help isolate the change and avoid introducing any other changes from the current sprint. Seeking stakeholder approval for the hotfix can help ensure compliance with the regulatory requirements and governance policies.

Kanban can help clarify whether value is being delivered to the business by using metrics, like lead time and throughput, which increase transparency. Lead time measures how long it takes to complete a work item from the time it is requested, and throughput measures how many work items are completed in a given time period. These metrics can help the business stakeholders see the progress and performance of the development teams, and align their expectations with the reality. Kanban does not respond to unplanned work and changes by dropping everything and jumping on the new request, as this would disrupt the flow and quality of work. Kanban does not make use of the Salesforce Agile Accelerator, as this is a tool for managing agile projects. Kanban does limit work in progress, but this is not the main reason why it can help clarify whether value is being delivered to the business.

 The Metadata API is mainly used for file-based deployment, such as deploying an application from a Developer Edition org to the AppExchange, or from a sandbox org to a production org. The Ant Migration Tool is a wrapper around the Metadata API, so it is not a direct use case for writing code to call retrieve() and deploy() methods. The Salesforce CLI (SFDX) uses the Source-Driven Development model, which relies on the source code as the source of truth, rather than the Metadata API.

Presenting the feature requests at a Center of Excellence meeting and creating the backlog or priority list in a project management tool are two options that can help to get feedback and prioritize the requests. A Center of Excellence meeting can provide a forum for discussing the business value, feasibility, and impact of the requests with the stakeholders. A project management tool can help to track, organize, and prioritize the requests based on the agreed criteria.

The most probable reason why none of the sandboxes can be refreshed is that the org has reached the maximum number of active sandboxes allowed by the license. Deleting the full sandbox used for performance testing will free up one sandbox slot and allow the other sandboxes to be refreshed. The Partial Copy sandbox is not the cause of the problem, as it counts as one sandbox slot. Creating a Salesforce support case or contacting the Salesforce Account Team may not resolve the issue in a timely manner.

The responsibility of the Technical Architect within a Change Control Board meeting is to approve the upcoming release for deployment into production, as they are the ones who have the authority and expertise to evaluate the quality and readiness of the release2. Option A is not correct, as prioritizing the Salesforce product roadmap with business stakeholders is not a task that is done in a Change Control Board meeting, but rather in a strategic planning session. Option B is not correct, as conducting code reviews for projects in the development phase is not a task that is done in a Change Control Board meeting, but rather in a code review session. Option C is not correct, as troubleshooting deployment errors that occurred during the last release is not a task that is done in a Change Control Board meeting, but rather in a post-deployment review session.

The recommended strategy for deploying a large volume of metadata is to identify metadata dependencies, create logical groupings, and deploy in the right order. This can help avoid errors and ensure a smooth deployment process.

 Executing all test classes in sandboxes can help identify and fix any errors or failures before deploying to production. Executing selected test classes in production can help reduce the deployment time and avoid running unnecessary tests.

A requirement traceability matrix is a project artifact that maps each requirement to its corresponding test cases, ensuring that all requirements are covered by testing. User acceptance test scripts are the actual steps to execute the test cases, not the artifact that links them to the requirements. Testing strategy and test execution plan are high-level documents that describe the overall approach and schedule for testing, not the specific mapping of requirements and test cases.

 The change set performance may depend on the included components, especially if they are complex or have many dependencies. The change set may take more time than usual if it includes changes to permission sets and profiles, as these components require additional validation and processing. The change set may not take more time if it includes field type changes, new custom objects and fields, or other simple components.

Utilizing a dedicated developer pro sandbox to address critical bugs and release to production is the recommended release management strategy, as it allows the development team to work on the new project without being interrupted by the bug fixes, and also ensures that the bug fixes are deployed to production as soon as possible. Including fixes for critical bugs in the ongoing development sandboxes is not recommended, as it may delay the release of the bug fixes and also introduce conflicts with the new code. Keeping teams separate until the end of the project and creating a full copy sandbox to merge their work then is not recommended, as it may create a lot of merge conflicts and integration issues. Addressing critical bugs in the development sandboxes and pushing those changes to production separately is not recommended, as it may create inconsistencies between the development and production environments.

The best deployment tool for UC to use to manage their deployment process in an automated fashion is the Force.com Migration Tool, as it is a command-line tool that uses the Metadata API to deploy components from one org to another, and can be integrated with version control systems and continuous integration servers. Option A is not a good choice, as Workbench is a web-based tool that does not support automation or scripting. Option C is not a good choice, as Change Sets are a point-and-click tool that require manual steps to create and deploy. Option D is not a good choice, as Force.com IDE is a desktop tool that does not support automation or scripting.

 Automated browser testing and static code quality analysis are two quality assurance techniques that can help minimize defects in software projects, and that an architect should recommend for Universal Containers to incorporate into its overall CI/CD pipeline. Automated browser testing is a technique that involves using tools or frameworks to simulate user interactions with the web application across different browsers and devices, and to verify the functionality and performance of the application. Static code quality analysis is a technique that involves using tools or frameworks to scan the code and detect any violations of the predefined coding rules and best practices, such as syntax errors, security issues, code smells, etc. Business verification testing and stress testing are also quality assurance techniques, but they are not as suitable or relevant for the CI/CD pipeline, as they are more focused on validating the business requirements and the system capacity.

The testing of the JavaScript part of the Aura component can be tested in the Jest framework and the Apex controllers can be tested using test classes. The testing can be viewed in the lightning.force.com/c/jasminetests.app URL. The page loads and runs Jasmine test and writes pass/fail information to the screen. The Lightning test service AppExchange package is not required for testing Aura components, but for testing Lightning web components. The $T test helper object is not a valid object for testing Lightning components.

 Fixing the issue in hotfix, testing, and deploying to production is the best option when UC has PI issues and has to be fixed immediately. A hotfix sandbox is a type of sandbox that is used for emergency fixes in production. It is a copy of the production org and has a shorter refresh interval than other sandboxes. A hotfix sandbox allows the team to quickly fix and test the issue without affecting the ongoing development and release cycles.

This is the correct answer because having developers work in separate branches and merge their changes in a common branch for testing can reduce the risk of overwriting others’ changes and ensure code quality and consistency. Having all developers work in the same branch or in the HEAD may cause conflicts and errors. Not using source control is not a good practice and may result in data loss and lack of version control.

B and D are the correct answers, as partner developer edition orgs and developer edition orgs are the appropriate environments for creating a managed package. A managed package is a collection of application components that are locked and versioned, and can be installed and upgraded in multiple orgs. A is incorrect, as developer pro sandbox orgs are not suitable for creating a managed package, as they are copies of a production org that are used for development and testing purposes. C is incorrect, as production orgs with LMA are not suitable for creating a managed package, as they are used for managing the licenses and subscribers of a managed package. You can learn more about this topic in the Package Development Model module on Trailhead.

The package development model relies on source tracking to automatically track the metadata changes in the package project. However, not all metadata components are supported by source tracking, and some changes may need to be tracked manually. For example, changes to profiles, permission sets, custom metadata types, and custom settings are not supported by source tracking. You can find the list of unsupported components here1. No manual tracking is required for the changes that are supported by source tracking, nor for the changes made via the Setup UI, as they are automatically captured by the package development model.

 Creating a Center of Excellence with a charter document is a recommended practice for managing multiple projects and aligning them with the business goals and roadmap. A Center of Excellence is a cross-functional team that provides guidance, support, and governance for the Salesforce ecosystem. A charter document defines the vision, mission, roles, and responsibilities of the Center of Excellence.

Announcing the maintenance window ahead of time, defining a rollback strategy, and temporarily suspending configuration changes in production are all best practices for production deployment. These practices help to minimize the risk of errors, downtime, and conflicts during the deployment process.

The reason why the Apex classes are not able to access the metadata of the target org during testing is that UC needs to get the managed package certified by the Salesforce security review. This is because Apex code in a managed package can only access the metadata of the target org if the package has passed the security review and has been granted the Modify Metadata permission. See Apex Metadata API for more details.

Manually validating change sets before deployment is a recommended practice to avoid possible delays while deploying a change set, as it can help you identify and resolve any errors or dependencies before the actual deployment. Change set performance is not independent of included components, as some components may take longer to deploy than others. Manually creating new custom objects and new custom fields or manually applying the field type changes are not advisable, as they can introduce human errors and inconsistencies between environments. See Deploy Changes with Change Sets for more details.

This is the correct answer because utilizing unit and functional test automation as part of a continuous integration strategy can prevent regression by ensuring that the code and configuration are always tested and validated before deployment. Utilizing the developer console to run test suites is not sufficient and may not cover all the functionality. Utilizing Salesforce Apex Hammer is not a feasible option as it is an internal tool that Salesforce uses to test customer orgs before major releases. Freezing development of new features and re-architecting the system is not a realistic or cost-effective approach to prevent regression.

 To support application lifecycle methodology, you need tools that can help you manage the source code, automate the deployment process, and track the issues and bugs. A version control repository is a tool that allows you to store, track, and collaborate on the source code of your application. A continuous integration tool is a tool that allows you to automate the deployment of your code to different environments, as well as run tests and validations. An issue tracking tool is a tool that allows you to record, monitor, and resolve the issues and bugs that arise during the development and testing phases. A database management system is a tool that allows you to store, manipulate, and query data, but it is not directly related to application lifecycle methodology. A middleware is a software layer that facilitates communication and data exchange between different applications, but it is not directly related to application lifecycle methodology either.

The sandbox types that the architect should recommend for batch data testing are Partial Copy sandbox and Full sandbox. These sandbox types allow the testing of large data sets that are similar to the production data.
