質問 2

A VPLEX administrator claims a 100GB Storage Volume that is thin provisioned on the storage array and has 25GB physically allocated and creates a 1:1 encapsulated virtual volume. After a local data mobility job for that Virtual Volume, the storage array administrator notices that the allocated capacity has increased to 100GB. Why did this happen?

（A）Neither the source nor the destination Storage Volume were claimed with the thin-rebuild parameter in VPLEX.

（B）The source Storage Volume was not claimed with the thin-rebuild parameter in VPLEX.

（C）The destination Storage Volume was not claimed with the thin-rebuild parameter in VPLEX.

（D）VPLEX does not support thin devices.

質問 8

Refer to the exhibit.

During a short power disruption to cluster 2, director-2-1-A failed. Power was restored after 5 minutes. In examining the output of the vault status command, you note that cluster-2's status reads "Cluster is not vaulting/unvaulting".
Why did this message appear?

（A）There was no power disruption at cluster-1

（B）The power disruption affected a single director only.

（C）The power disruption did not affect all "A" directors.

（D）The vaulting process runs on cluster-1

質問 11

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.
