The Ansible playbook is designed to reset configurations on Cisco IOS XE routers. It includes tasks to remove Loopback1 and Loopback2 interfaces. The condition when: "'pod-2' in ansible_net_hostname" ensures that Loopback2 is only removed from routers with ‘pod-2’ in their hostname. Since pod-11 and pod-12 do not meet this condition, only Loopback1 is removed from them, which leads to the removal of IPv4 and IPv6 addresses for the Loopback1 interface on these routers. References: Automating Cisco Enterprise Solutions Official Cert Guide

 MQTT is a lightweight messaging protocol that operates on a publish-subscribe model, allowing clients to subscribe to topics and receive messages sent to those topics by any client. It is designed for connections with remote locations where a small code footprint is required or network bandwidth is limited.

 To remove a device from the network ‘ENAUTO’ using Meraki APIs, the engineer must send an HTTP DELETE request to the Meraki API endpoint for device removal. The correct line of code to be added should specify the DELETE method, the URL for the API endpoint, and include headers that typically contain authentication information. Option B is correct because it uses requests.request('DELETE', url, headers=headers) which specifies the DELETE method and includes both the URL and necessary headers. References: Automating Cisco Enterprise Solutions Official Cert Guide

The Meraki Location Scanning API is designed to provide location-based services. Mapping and wayfinding solutions are built using this API to help users navigate physical spaces, making options B and E the correct answers. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

To insert the project into Git using the account python_programmer, one would need to initialize the local directory as a Git repository, add files to it, commit those files with an appropriate message, add a remote repository URL pointing to where the repository should be pushed on GitHub under python_programmer’s account, and finally push the changes up to that remote repository. Option A follows this process correctly: ‘git init’ initializes the local directory as a Git repository; ‘git add “device_status.py”’ stages changes; ‘git commit -m “Initial Revision”’ commits staged changes with message; ‘git remote add origin 6’ adds new remote repo; ‘git push -u origin master’ pushes committed changes up to GitHub. References: = Automating Cisco Enterprise Solutions Official Cert Guide

To remove an administrator from a Meraki network using an API call, the correct URI is “DELETE https://api/meraki.com/api/v0/organizations/ /admins/<admin_id>”. This DELETE request removes the specified admin identified by <admin_id> from the organization identified by . References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

When integrating a Grafana dashboard with Cisco DNA Center to receive network events, the integration bundle that is enabled is:

• C: Network Events for REST API Endpoint. This integration allows Grafana to receive network event notifications from Cisco DNA Center. The REST API Endpoint serves as the interface through which Grafana can subscribe to and receive network events, which can then be visualized on the dashboard1.

The ENAUTO exam tests knowledge of implementing enterprise automated solutions, including programming concepts, Python programming, APIs, controllers, and automation tools. Without the specific Python code from the exhibit, I can’t provide the expected output. Generally, Python code in the context of ENAUTO might involve interacting with APIs or automating network configurations. The output would depend on the code’s function, such as retrieving data from an API or configuring network devices. References := Automating Cisco Enterprise Solutions Official Cert Guide

To construct this URL, one needs to understand REST API call structure and how it relates to Cisco SD-WAN vManage APIs specifically. The base URL starts with ‘https://’, followed by ‘vmanage-ip-address’ which should be replaced with the actual IP address or hostname of vManage. ‘/dataservice/’ is a common prefix in all vManage REST API calls indicating that data service is being accessed. Following this, ‘/device/bfd/sessions/history’ specifies that we are interested in accessing historical data about Bidirectional Forwarding Detection sessions on devices. Finally, ‘?deviceId=’ is a query parameter where one must provide an actual device ID instead of ‘ ’ placeholder. References: ( Automating Cisco Enterprise Solutions Official Cert Guide )

In Cisco DNA Center Operational Tool API, the Command Runner section of the intent API is designed to retrieve keywords accepted by CLI and enables execution of read-only commands on network devices. This feature allows administrators to retrieve real-time configuration data from devices without making any changes, aiding in monitoring and troubleshooting tasks. References: Automating Cisco Enterprise Solutions Official Cert Guide

Synchronous calls to APIs are characterized by their blocking nature, meaning the process making the request must wait until it gets a reply before it can proceed with other tasks. This can add perceived latency to an application if there is a delay in receiving data. Synchronous APIs provide immediate feedback, which is essential for operations requiring instant confirmation and interaction4567. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

To create a Cisco Meraki network, the REST API endpoint that should be used is “POST /organizations/{organizationId}/networks”. This POST request is used to create a new network under an organization specified by the {organizationId}. The body of the request would typically include parameters such as name, type, and timezone among others. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

The Cisco SD-WAN vManage Certificate Management API is primarily used for certificate-related operations within the SD-WAN fabric. The correct purpose of using this API is:

• A: To generate a Certificate Signing Request (CSR). The CSR is a request sent from an applicant to a certificate authority to apply for a digital identity certificate. It contains information that will be included in the certificate, such as the applicant’s public key and organization details. Once the CSR is generated, it can be signed by a Certificate Authority (CA) to create a certificate1.

 To attach a device template in Cisco SD-WAN, you must issue a POST call to initiate the attach action. This is the first step in the process. After initiating the attach action, you need to monitor the status of the action. For this, you issue a “monitor device action status” GET API request with the process ID. The process ID is used to track the status of the attach action until it is completed.

 To create a new feature in a separate branch and check out the new version, the correct commands are needed. Option B provides the correct sequence of Git commands to achieve this task. The command git checkout -b feature creates a new branch named “feature” and switches to it immediately, which is exactly what is required when starting development on a new feature while keeping the production release intact in the “master” branch. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

 Software-defined networks (SDNs) offer several advantages over traditional networks; one key advantage is their distributed management architecture. Unlike traditional networks where the control plane (which makes decisions about where traffic should be sent) and the data plane (which actually sends packets according to those decisions) are coupled on each networking device leading to potential single points of failure, SDNs separate these planes. This separation allows for centralized control with a global view of the network state while maintaining local data forwarding at each switch. This architecture enhances resilience as it can dynamically adjust and reroute traffic around failed nodes or congested paths without manual intervention. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

To add legacy devices to the Cisco DNA Center platform, it is essential to update the trusted device profile and create device packages. These steps ensure that the legacy devices are recognized and managed correctly by the Cisco DNA Center. Updating the trusted device profile allows the platform to authenticate and trust the legacy devices, while creating device packages enables the platform to understand and interact with the specific features and capabilities of the legacy devices123. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

NETCONF, unlike RESTCONF, allows for the validation of a candidate datastore before it is committed as the running configuration. This feature ensures that any configuration changes are checked for correctness before they can potentially impact the network operation. 

 In RESTCONF API calls, when specifying the content type in HTTP headers for requests or responses involving YANG-modeled data, ‘yang-data+json’ is used as part of the ‘Accept’ or ‘Content-Type’ headers to indicate that the message body contains JSON-encoded YANG-modeled data.

In this Python script using RESTCONF, ‘yang-data+json’ completes the highlighted areas because it specifies that JSON format is expected in response which conforms with YANG data modeling standards.

• The ncclient library is used for NETCONF communication with network devices.
• To retrieve interface information, you need to use the get operation.
• The get operation allows you to retrieve configuration and operational data from the device.
• In the context of the question, the engineer is creating a Python script to retrieve interface information.
• The correct expression to complete the highlighted section is intf_config, which represents the configuration data for the specified interface.

 In Ansible, the state parameter is used to define the desired state of a resource on the remote device. The options typically include “present” or “absent,” indicating whether the resource should exist or not. In this context, “present” is used to ensure that the VRFs defined in the local_vrfs variable are configured on the target device. Therefore, the string that completes the code for configuring VRF information using a local_vrfs variable is “present.” References: = Automating Cisco Enterprise Solutions Official Cert Guide

In Ansible, the ‘state’ parameter is used to specify the desired state of a resource on the target system. For configuring an NTP server on a Cisco IOS XE device, ‘state: present’ ensures that the NTP server with the specified IP address is configured on the device. The options ‘true’, ‘started’, and ‘installed’ are not valid states for this type of resource in Ansible. The ‘present’ state is used to ensure that an entity exists, which in this case refers to making sure that the NTP server configuration exists without authentication and logging.
