EMC Proven Professional – XtremIO Solutions Expert — Question 9

SRDF/Metro has been deployed between two data centers. SRDF/Metro is operating normally. Maintenance tasks at the R1 data center require the array to be offline.
Which SRDF operation should be executed on the Metro RDF pairs to facilitate the planned outage without affecting application I/O?

Answer options

• A. Failover
• B. Split with bias set to R2
• C. Suspend with bias set to R2
• D. Swap

Correct answer: A

Explanation

The correct answer is A, Failover, because it allows the application to continue running on the R2 site while the R1 array is taken offline for maintenance. The other options, such as Split or Suspend, do not provide the same level of availability for application I/O during the outage.
