A. Partial Receive Delta Set data is applied

B. Receive Delta Set data is discarded

C. Session is marked as Cleanup required

D. Session is marked as Partitioned

A VMAX3 array has been configured to use TimeFinder SnapVX. A snapshot is taken of a LUN that currently resides on a 10k drive. Which mechanism will SnapVX use when there is a write to a linked target volume?

A. COFW

B. ROW

C. ACORW

D. COW

Which feature does the embedded eDPM server support on a VMAX3?

B. FAST.X

C. D@RE

D. ESRS

In an SRDF/Metro environment, where is the vWitness lock service, -storwlsd, running?

A. On the vWitness instance

B. On the target array

C. On the source array

D. On the production host

Based on business requirements, Concurrent SRDF/Star has been implemented with host infrastructure at the Workload and Asynchronous sites. A disaster fault has occurred. Star query shows:

Which site should the workload be moved to and which site's data should be kept?

A. Switch to the Synchronous site Keep the Synchronous site data

B. Switch to the Asynchronous site Keep the Asynchronous site data

C. Switch to the Synchronous site Keep the Asynchronous site data

D. Switch to the Asynchronous site Keep the Synchronous site data

Refer to the Exhibit.

Migration of data from a VMAX to a VMAX All Flash array is planned. the target array has been installed and RDF connectivity between the two arrays has been established. In addition, the application host is accessing data on the source array.

What is the result when the Non-Disruptive Migration Setup operation is performed?

A. Creates RDF pairs and places them in pass-through mode

B. Replicates the storage configuration from the source to the target array

C. Creates an empty Dynamic RDF group on the source and target arrays

D. Zones the application host initiators to the target array

XtremIO is part of a company's FAST.X environment with a VMAX All Flash array and will remain as part of the configuration. The VMAX All Flash array is configured for SRDF as well. In addition, a large VMware environment is hosted on the XtremIO, however, the VMware datastore devices are not virtualized to the VMAX All Flash array.

If the company wants to have remote replication for the VMware devices, how can this be accomplished?

A. Virtualize the VMware datastore devices using incorporation and add to the SRDF configuration

B. Connect an additional VMAX3 or VMAX All Flash array to the XtremIO array and enable SRDF

C. Virtualize the VMware datastore devices using encapsulation and add to the SRDF configuration

D. Enable SRDF on the XtremIO array and add the VMware datastore devices to the configuration

Based on the exhibit, where is data considered to be in motion?

A. SAN and replication network

B. Host, SAN, and arrays

C. Host and arrays

D. SAN, arrays, and replication network

On a VMAX3 array, for which type of workload does FlashBoost help in optimizing performance?

A. Sequential Reads

B. Sequential Writes

C. Random Writes

D. Random Reads

What is a benefit of SRDF R22 devices in a VMAX3?

A. Allows simultaneous replication of a source device to two different target devices

B. Allows simulations replication of two source devices to the same target device

C. Makes SRDF/Star more resilient

D. Makes Cascaded SRDF more resilient
