Dell EMC Specialist – Implementation Engineer, PowerEdge Server — Question 42

What is a characteristic of SRDF/Metro?

Answer options

• A. Data must be stored in cache on both sides before an acknowledgement is sent to the host.
• B. Multiple capture sets permit smaller cycles of data to be buffered on the R1 side and transferred to the R2 side.
• C. A dependent-write consistent copy is maintained between the R1 and R2 devices.
• D. Devices that have the Consistency Exempt attribute set can be controlled independently of the other devices.

Correct answer: C

Explanation

The correct answer is C because SRDF/Metro ensures that a dependent-write consistent copy exists between the R1 and R2 devices, which is crucial for maintaining data integrity during operations. Option A is incorrect as it describes a different caching behavior, while options B and D refer to different features that do not define the primary characteristic of SRDF/Metro.
