EMC Proven Professional – PowerMax Specialist — Question 29

A storage administrator wants to asynchronously replicate a compressed LUN from the primary site to a Unity at the secondary site. Which statement describes this operation?

Answer options

• A. Replication of compresses data is controlled by the bandwidth throttle setting.
• B. By default, replication compresses data sent to the destination.
• C. The source data is uncompressed, then replicated to the destination.
• D. The source data is replicated to the destination, then uncompressed.

Correct answer: D

Explanation

The correct answer is D because during the replication process, the source data remains in its compressed state until it is sent to the destination, where it is then uncompressed. Option A is incorrect as bandwidth throttling does not control the compression state during replication. Option B is misleading since the default behavior is to replicate the data as is, and it does not apply compression to the data being sent. Option C is incorrect because it misrepresents the sequence of operations, suggesting uncompression occurs prior to replication.
