After an extended outage of the primary site, a large number of invalid tracks have accumulated on the R2 devices.
What can be done to minimize application response time impact, when resuming production on R1 devices?

• A.Run a restore command
• B.Invalidate the tracks on R1, write-disable R1, and refresh R1
• C.Run an R1 update followed by a failback
• D.Write-disable R2 and merge the track tables

Refer to the exhibit.

A Symmetrix is configured with two RDF groups, RDFG 1 and RDFG 2, as shown. The SRDF R1 devices used by Application 1 (App 1) and Application 2 (App 2) are in RDFG 1. The SRDF devices used by Application 3 (App 3) are in RDFG 2.
What should be created to enable SRDF/A for App 1 and App 2?

• A.Two device groups, one with the App 1 devices and another with the App 2 devices
• B.Two files, one with the App 1 devices and another with the App 2 devices
• C.One file with all the devices in RDFG 1 and RDFG 2
• D.One device group with all the devices in RDFG 1

What type of data can a Unisphere for VMAX CSV performance report contain?

• A.24 hours of real time data
• B.6 months of diagnostic data
• C.4 months of real time data
• D.4 hours of diagnostic data

What are dynamic reallocation volumes (DRV) used for within a Symmetrix VMAX array?

• A.Virtual LUN Migration
• B.FAST VP Swaps
• C.TimeFinder/Snap
• D.FAST DP Swaps

Refer to the exhibit.

An Oracle database server has its logs and data split between two Symmetrix V-Max arrays at the primary site. Synchronous consistency protection was enabled for the log and the data devices.
What will occur if the link between the Symmetrix V-Max array containing the log LUNs and the target Symmetrix V-Max array were to fail?

• A.R1 volumes in the Source array, containing the log LUNs, will become write-disabled to the database server.
• B.R2 data remains consistent because Enginuity Consistency Assist (RDF-ECA) technology ensures data consistency.
• C.SRDF failover would be initiated on all volumes and processing automatically switches over to the Remote Site.
• D.Data in the database becomes inconsistent at the Remote Site.
