Question 4

A customer has purchased a dual engine VPLEX Metro cluster. During installation, there are not enough free SAN ports to connect all WAN-COM ports to the SAN. What is the recommended approach?

A. The customer must provide additional SAN ports or acquire additional SAN ports to connect all WAN-COM ports of both VPLEX engines to the SAN.

B. It is sufficient to connect the WAN-COM ports of either engine 1 or 2 because redundancy is provided by leveraging two separate SAN fabrics.

C. The customer must connect the WAN-COM ports of the first engine only and disable the second engine from the Unisphere for VPLEX GUI.

D. The customer must connect the WAN-COM ports of the first engine only and disable the second engine from the VPLEX CLI.

Correct Answer: A

D. Global

Correct Answer: C

Question 6

What is EMC's best practice for fault tolerance when zoning a VPLEX Metro together over fibre channel for successful communication between the sites?

A. Ensure that all fibre channel Local-COM ports are zoned to the WAN-COM ports in both SAN fabrics (One-to-Many Zoning).

B. Ensure that all fibre channel WAN-COM ports are zoned to each other in both SAN fabrics (Many-to-Many Zoning).

C. Ensure that all fibre channel Local-COM ports are zoned to each other in both SAN fabrics (Many-to-Many Zoning).

D. Ensure that all fibre channel WAN-COM ports are zoned to each other in both SAN fabrics (One-to-Many Zoning).

Correct Answer: D

Question 7

Refer to the exhibit.

You are preparing to perform an upgrade on an unconfigured VPLEX Metro. When you run the ndu pre-check command, it indicates that it has failed and there are no first upgraders. In your troubleshooting, you run the version -a command.

D. The engine will shut down immediately.

Correct Answer: C

Question 9

Refer to the exhibit.

The customer has not followed EMC best practices when cabling their VS2 VPLEX engine. What action would you recommend to fix this issue?

A. Add two more additional fabrics and place each director in its own fabric.

B. Swap ports 00 with ports 01 of both director A and director B.

C. Swap port 02 with port 03 of both director A and director

D. Separate all FE and BE ports into their own fabric.

Correct Answer: B

Question 10

In a customer's VPLEX Metro environment, a host has been provisioned as a single virtual volume from cluster-1. The customer now needs to convert the local virtual volume to a distributed device.
How can the customer accomplish this?

A. Add an unused virtual volume from cluster-2 as a remote mirror to the virtual volume on cluster

B. Enable remote access to an unused device from cluster-2 and add it as a remote mirror.

C. Add an unused device from cluster-2 as a remote mirror to the virtual volume on cluster-1

D. Enable remote access to an unused virtual volume from cluster-2 and add it as a remote mirror.

Correct Answer: C
