EMC Proven Professional – Isilon Specialist — Question 1

A VMAX3 array has been configured with two Storage Resource Pools (SRP). Source volumes are assigned to SRP_1 and target volumes are assigned to
SRP_2. A TimeFinder SnapVX snapshot of the source volumes is linked to the target volumes in the default mode.
What will happen when there are new host writes to the source volumes?

Answer options

• A. Snapshot deltas will be stored in SRP_1
• B. Snapshot deltas will be stored in SRP_2
• C. Snapshot deltas will be stored in the Reserved Capacity of SRP_1
• D. Snapshot deltas will be stored in the Reserved Capacity of SRP_2

Correct answer: B

Explanation

The correct answer is B because when new writes occur to the source volumes, the snapshot deltas are recorded in the target volumes' storage pool, which is SRP_2. Options A and C are incorrect as they wrongly suggest that the deltas would be stored in SRP_1, which is not the case since it is the source pool. Option D is also incorrect since it refers to reserved capacity, which is not where the deltas are stored in this scenario.
