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

A VDI deployment is planned for an environment that consists of VMAX3 and XtremIO. The data will have a high degree of deduplication and will require QoS and VVOL support. How can the existing infrastructure be leverage while minimizing increased storage capacity?

A. Use XtremIO for the new deployment

B. Use FAST.X with XtremIO for the new deployment

C. Add full capacity required for VMAX3

D. Add half the capacity required for the VMAX and use compression

A server is hosting an online application and is experiencing performance issues. Which component of the architectural layer has the lowest probability of impacting performance?

A. Operating System

B. Server

C. Application

D. Disk

An existing single engine VMAX3 with two FC ports configured for remote replication will be adding FAST.X to a CloudArray. Currently the array is configured with 32 FC ports which are all in use.

Which steps are required to support a minimum connectivity to the CloudArray?

A. Identify a port on each director to be used for the DX emulation Remove replication from any devices on the selected ports Delete any volumes presented to those ports

B. Identify two ports on each director to be used for the DX emulation. Stop all remote replication Delete any volumes presented to those ports.

C. Identify two ports on a single director to be used for the DX emulation Remove any masking entries related to the director ports

D. Identify two ports on each director to be used for the DX emulation Remove any masking entries to the director ports.

B. Witness RDF group on the witness array containing the source and the target SRDF/Metro devices

C. One RDF group on the witness array to both the source and the target

D. Two RDF groups on the witness array; one to the source and one to the target
