Questions # 14:

A service provider has implemented a VPLEX Metro cluster without the VPLEX Witness, but has implemented a static rule set. The static rule set has been set to "Cluster-2 detaches". A Windows host in the Cluster-1 data center uses a distributed volume. The inter-cluster link fails. What happens?

Options:

A.

1. VPLEX Suspends I/O to all distributed devices on both clusters

2. VPLEX starts a delay timer

3. If connectivity is not restored within the timer expiration period, then VPLEX will resume I/O on Cluster-2 and keep I/O suspended on Cluster-1


B.

1. VPLEX starts a delay timer

2. VPLEX suspends I/O to all distributed devices on both clusters

3. If connectivity is not restored within the timer expiration period, then VPLEX resumes I/O on Cluster-2 and keeps I/O suspended on Cluster-1


C.

1. VPLEX starts a delay timer

2. VPLEX suspends I/O to all distributed devices on both clusters

3. If connectivity is not restored within the timer expiration period, then VPLEX resumes I/O on Cluster-1 and keeps I/O suspended on Cluster-2


D.

1. VPLEX suspends I/O to all distributed devices on both clusters

2. VPLEX starts a delay timer

3. If connectivity is not restored within the timer expiration period, then VPLEX resumes I/O on Cluster-1 and keeps I/O suspended on Cluster-2

Questions # 15:

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?

Options:

A.

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


B.

VPLEX does not support thin devices.


C.

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


D.

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

Questions # 20:

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

Options:

A.

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


B.

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