The production work must be suspended until the host on site A can be restored.B. The host on site B can access the R1 Volumes through the SRDF links and continue theproduction work with the R1 Volumes.C. An SRDF failover operation must be executed for the SRDF pairs. The production work couldthen be restarted on the host on site B.D. The Symmetrix will detect the failure and automatically write-enable the R2 Volumes. Theproduction work could then be restarted on the host on site B.Answer: CQUESTION: 19Click the Exhibit button.In the SRDF/AR Single Hop scenario shown in the graphic, the Source site has becomeunavailable. At the time of failure all BCV pairs were Split, and the Source R1-BCV to TargetR2 synchronization was not complete. It is necessary to restart the application at the Target site,while maintaining an additional clean copy of the data in case of corruption during the restartprocedure. Which procedure would achieve this restart objective?9http://www.certmagic.comE20-510A.1. Check for device locks on the Target site BCV devices2. Suspend RDF links and Write-enable the BCV devices3.
