Cyber recovery is a process of restoring critical data and systems in the event of a cyber attack. This goal of this process is to ensure that a copy of the data is always available, even if the original data has been corrupted or compromised. This can be done by isolating a copy of the data and keeping it separate from the original. This ensures that the data is always available should a cyber attack occur, allowing the business to quickly restore the original data and continue operations.

In a RAID 1 array, data is mirrored across two disks. So when a host sends one write I/O to the array, the array will perform two write I/Os to store the data on both disks. The other options are incorrect because they do not accurately reflect the number of write I/Os required in a RAID 1 array.

The Management plane of the Software-Defined Data Center (SDDC) architecture provides a graphical user interface (GUI) and command-line interface (CLI) for IT administrators to manage and configure the infrastructure, including storage resources. The management plane is responsible for providing visibility, automation, and orchestration of the SDDC components. It enables IT administrators to monitor and manage the infrastructure, configure policies, and allocate resources as needed. Reference: Section 1.1 Introduction to Software-Defined Data Center (SDDC), page 5.

An OSD storage system is an object-based storage system that stores data as objects rather than files or blocks1. An OSD storage system consists of OSD nodes that have two key services: metadata service and storage service1.

The metadata service is responsible for generating the object ID from the contents of a file1. The object ID is a unique identifier that represents the data and its attributes. The metadata service also maintains the mapping of the object IDs and the file system namespace1. The file system namespace is a logical structure that organizes files into directories and subdirectories.

The storage service manages a set of disks on which the user data is stored1. The storage service stores data as objects in physical OSD containers. Each OSD container has a unique address that corresponds to an object ID. The storage service also handles requests from clients to read or write data to or from objects.

Virtual LANs (VLANs) are used to segment a physical LAN into multiple logical LANs. This allows multiple networks to share a single physical LAN while maintaining the logical separation between the networks. Each VLAN is assigned a unique identifier and each network device is configured with the identifier of the VLAN it belongs to. This allows traffic from different VLANs to be identified and routed accordingly. VLANs provide an additional layer of security by ensuring that devices on one VLAN cannot access the traffic of another VLAN.

Archive is a type of data protection that is used to move primary data to lower cost storage and helps to enforce compliance requirements. It is a process of moving inactive data that is no longer needed for immediate use to a secondary storage medium. Archive uses data compression and deduplication techniques to reduce storage costs, and can also be used to help meet compliance requirements.

Consumers have control over deployed applications and application hosting environment configurations.

MDM is a control that restricts access to an organization’s resources only to authorized mobile devices.

an FC frame consists of five parts: start of frame (SOF), frame header, data field, cyclic redundancy check (CRC), and end of frame (EOF). The SOF and EOF act as delimiters. The frame header is 24 bytes long and contains addressing information for the frame.
