Dell EMC Exam D-PVM-OE-01 Topic 4 Question 9 Discussion

Step by Step Comprehensive Detailed

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.
