The topology shown in the exhibit depicts Cascaded SRDF. This SRDF configuration involves three storage arrays (or sites) connected in a chained or cascaded manner.

Here's how it works:

Primary Site (R1): The production host is connected to the primary storage array (R1).

Intermediate Site (R2): The primary array (R1) synchronously replicates data to an intermediate array (R2).

Remote Site (R2): The intermediate array (R2) then asynchronously replicates data to a remote array (also labeled R2 in the diagram).

This cascading setup provides a multi-hop disaster recovery solution, where data is first replicated synchronously to a nearby site for high availability and then asynchronously replicated to a further remote site for disaster recovery.

Why other options are incorrect:

B . SRDF/Star: SRDF/Star involves a central array replicating to multiple remote arrays in a star-like pattern.

C . SRDF/Metro: SRDF/Metro is designed for synchronous replication over short distances, typically within a metropolitan area.

D . Concurrent SRDF: Concurrent SRDF allows multiple SRDF relationships to exist simultaneously for the same device.

SnapVX Linked Targets: SnapVX is a snapshot technology used in Dell PowerMax storage arrays. A linked target is a volume that provides read/write access to a specific point-in-time copy (snapshot) of a source volume.

Read/Write Access: Unlike traditional snapshots, which are typically read-only, SnapVX linked targets allow modifications. This makes them suitable for use cases like testing, development, and data analysis where changes need to be made to a copy of the data without affecting the original source.

Secure Snapshots: SnapVX offers the capability to create 'secure snapshots.' These snapshots are write-protected and prevent any modifications or deletion, ensuring data integrity and protection against accidental or malicious changes.

Why other options are incorrect:

B . They support a maximum of 1024 snaps per volume: This is partially correct. While a source volume can have up to 1024 snapshots, this limit includes all types of snapshots (manual, automated, and legacy), not just linked targets.

B . They cannot send data to SRDF: This is incorrect. SnapVX linked targets can participate in SRDF (Symmetrix Remote Data Facility) replication, allowing for disaster recovery and data mobility.

To register an ESXi server in Unisphere for PowerMax, you need to provide the following information:

IP Address: The IP address of the ESXi server that you want to manage. This allows Unisphere to communicate with the ESXi host.

ESXi Server Credentials: The username and password of an account with sufficient privileges to access and manage the ESXi server. This ensures that Unisphere has the necessary permissions to perform storage-related operations on the ESXi host.

Why other options are incorrect:

A . Unisphere credentials and hostname: Unisphere credentials are used to log in to Unisphere itself, not to register an ESXi server.

B . IP address and hostname: While the hostname might be helpful, the ESXi server credentials are essential for authentication and authorization.

D . ESXi server credentials and Unisphere credentials: Unisphere credentials are not required for registering an ESXi server.

TimeFinder SnapVX is a snapshot technology in PowerMax that allows you to create point-in-time copies of data. When using SnapVX, you can link target volumes to a snapshot to create writable copies of the data at that specific point in time.

The maximum number of target volumes that can be linked to a single snapshot on a source volume is 255. This limitation ensures efficient management and performance of the SnapVX snapshots and linked targets.

Why other options are incorrect:

B . 256, C. 512, D. 1024: These numbers exceed the maximum limit of linked targets per snapshot.

A Gatekeeper in PowerMax is a small, dedicated device used for communication between the storage array and Solutions Enabler (SYMCLI), the command-line management interface. The default size of a Gatekeeper on a PowerMax array is 3 cylinders.

While the size can technically be specified in kilobytes (KB), the traditional and preferred unit for Gatekeeper size is cylinders. This is because cylinders represent a specific number of blocks on the physical disks, and using cylinders helps ensure consistent sizing across different disk types and configurations.

Why other options are incorrect:

A . 3 KB, C. 6 KB: These sizes are too small to be practical for a Gatekeeper.
