After the "attach-mirror" command is successfully executed on device "device_VNX0506_CSE__6_1",
the command "rebuild-status" shows an ongoing rebuild process on the same device.
What is a possible cause?

• A. It is a normal behavior. when attaching a mirror, a rebuild process starts.
• B. The device "device_VNX0506_CSE__6_1" has an ongoing rebuild process for a previous failure.
• C. The rebuild process is related to a director failure.
• D. The device mirror will start only after the rebuild process is completed.

Refer to the exhibit.

What is the result of the command?

• A. clustermirror becomes a top-level device but without any virtual volume created or guarantees about its data.
• B. clustermirror becomes a top-level device, and a virtual volume is created for the device if the parent had a virtual volume.
• C. clustermirror is broken down to its base extents.
• D. clustermirror is detached and discarded.

Refer to the exhibit.

You are preparing to upgrade a VPLEX Metro system. You ran the version command to begin the
verification process and received the output shown.
What is the most likely reason for the warning?

• B. The Cluster Witness is at the wrong version.
• C. The Management Server is at the wrong version.
• D. The directors are in an NDU state.

Refer to the exhibit.

What is the purpose of VPLEX Witness in a Metro environment?

• A. Prevent cluster link failure and stop I/O transfer. Split consistency groups and failover consistency groups.
• B. Send notifications and pause I/O transfer. Initiate vault dump and failover consistency groups.
• C. Observe state of the clusters and suspend I/O. Execute health check and resume I/O.
• D. Observe the state of the clusters and distinguish link outages. Intercluster failures and resume or suspend I/O.

Refer to the exhibit.
