Dell EMC Specialist – Systems Administrator, PowerEdge Server — Question 9

Two PowerMax arrays have been configured for replication using SRDF. During a disaster recovery operation, production has been transferred to the R2 devices at the target site. Which operation begins the transfer of accumulated invalid tracks from the R2s to the R1s while production work continues on the R2s?

Answer options

• A. Failback
• B. Failover
• C. Resume
• D. Update

Correct answer: A

Explanation

The correct answer is Failback, as it refers to the process of transferring accumulated invalid tracks from the R2 devices back to the R1 devices after a failover. Failover is the initial switch to R2s, while Resume and Update do not pertain to the transfer of invalid tracks during ongoing production.
