identically configured VNX was implemented and the customer created two additional datastores

on the new VNX.

are not using the same sub-block structure as the two new datastores.

What is the reason for this behavior?

A. The old VMs are on an upgraded VMFS-5 datastore.

B. The old VMs are still running old VMware tools.

C. The new VMFS-5 features need to be licensed and activated.

D. The new VMFS-5 cannot support two VNX storage systems.

Answer: A

QUESTION NO: 8

A customer requires an asynchronous DR solution for an NFS-only client environment. The

customer wants the solution to be simple to implement. It was recommended they create a single

NIS domain, and use several NIS servers to provide centralized authentication to the NFS clients

at both the source and destination sites. The customer asks you whether they should consider

using VDMs in this environment. What do you advise?

A. VDMs would offer no advantages to this environment.

B. VDMs allow VMWare integration of NFS service environments.

C. VDMs eliminate the need for Usermapper in NFS environments.

D. VDMs allow for assignment of specific CPUs to a NFS server.

Answer: A

QUESTION NO: 7

An administrator is attempting to vMotion a VM from one vSphere ESXi 5.0 host to another. The

ESXi servers are connected to three VNX arrays on the fabric. The vMotion fails. What is the

most likely reason?

A. RDMs are attached to the VM with different host LUN numbers on the ESXi servers.

B. There are active SnapView sessions on the VM preventing the vMotion.

C. RDMs are in physical compatibility mode and not eligible for vMotion.

D. There are active MirrorView sessions on the VM preventing the vMotion.

Answer: A

QUESTION NO: 4

QUESTION NO: 1

A customer wants to replicate a CIFS environment from a legacy EMC Celerra to a new EMC

VNX. Users are able to access CIFS shares from both arrays. The CIFS shares are on different

networks and replication is not running. The customer wants to make sure there will be no

network restrictions preventing replication between the data movers on two different networks.

What TCP ports should they ask the network team to open?

A. 8888, 8887, 5081

B. 80, 443, 8080

A customer has an Oracle ASM database on an EMC VNX with FAST Suite enabled. They

observe intermittent performance degradation due to momentary data hot spots caused by bursty

transaction rates. What recommendation would you make to help alleviate these hot spots?

A. Enable Fast VP on the ASM LUNs

B. Modify the ASM rebalance power priority

C. Enable Fast Cache on the ASM LUNs

D. Disable ASM storage management

Answer: C

QUESTION NO: 10

A customer has a Windows-only environment connected to an EMC VNX for File at their main

campus site. The customer plans to install a new EMC VNX at a remote branch office site. The

new VNX will be used to implement a DR solution for their main campus VNX using several

deduplicated file systems shared and available to clients via CIFS.

A. Use VNX Replicator to replicate the VNX VDMs and associated file systems from the main

campus site to the VNX system at the branch office site to provide an asynchronous DR solution.

B. Use VNX Replicator to replicate the VNX VDMs and associated file systems from the main

campus site to the VNX system at the branch office site to provide a synchronous DR solution.

C. Use VNX SAN Copy to replicate the VNX block devices associated with the VNX file systems

from the main campus site to the VNX system at the branch office site to provide a synchronous

DR solution.

D. Use VNX MirrorView/A to replicate the VNX block devices associated with the VNX file systems

from the main campus site to the VNX system at the branch office site to provide an asynchronous

DR solution.

Answer: A

QUESTION NO: 6

A customer recently purchased an EMC VNX to be connected to four ESXi 5.0 hosts via FC. Five

of the associated VMs (virtual machines) are running SQL Server 2008 R2. To avoid contention,

Which ESXi 5.0 feature would satisfy this requirement?

A. Network interface card teaming

B. Virtual Machine Anti-Affinity

C. Raw Device Mappings

D. VMDK Affinity

Answer: B

QUESTION NO: 11

A system administrator wants to migrate medical-imaging data stored on an EMC VNX. The host
