Answer : A

A customer recently upgraded from vSphere v4.x to vSphere v5.0 to benefit from new
VMFS-5 features for their existing DataStore1 and DataStore2 datastores on an EMC
VNX. A second identically configured VNX was implemented and the customer created two additional datastores on the new VNX.
After monitoring the environment, the customer notices the VMs on DataStore1 and
DataStore2 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

You have completed the installation of a RecoverPoint/SE cluster using Deployment
Manager. You log into Unisphere for the VNX and look at the Storage Group for the RPAs.

  • A. Cluster repository only
  • B. Cluster repository and all selected replication volumes
  • C. Cluster journal only
  • D. All repository, journal, and replication volumes


Answer : A

A customer uses Replication Manager Version 5 to make replicas of their Windows 2003 server. The customer installs a new Windows 2008 server and tries to mount the replica.
The customer reports they cannot mount the replica to the new server. What is the likely issue?

  • A. Windows 2003 data can only be mounted on Windows 2003 hosts.
  • B. Replication Manager is not installed on the new server.
  • C. Replication Manager only supports Windows 2003.
  • D. Windows 2008 Replication License is installed.

  • B. The link is down.
  • C. The link is disabled.
  • D. Beaconing is enabled for the port.


Answer : A

A customer has three production hosts connected to a VNX. Each host has two 150 GB
LUNs in the same RAID 5 (4+1) RAID group. Replication Manager is configured to take
SnapView snapshots of the production host LUNs for local backups using a dedicated backup host. The RLP (reserved LUN pool) is configured on the same RAID group as the production host LUNs. The customer reports there are performance slowdowns during backups.
What is the best solution?

  • A. Stop the snapshots, remove the LUNs from the RLP, create a new RAID 5 (4+1) group and new LUNs, and add the new LUNs to the RLP.
  • B. Expand the source LUN RAID group to a RAID 5 (8+1) RAID group, and expand the sizes of the reserved LUNs to twice their original value.
  • C. Create a new RAID 5 (4+1) RAID group, create new LUNs on the RAID group, and perform a LUN migration on the RLP LUNs to the new RAID group.
  • D. Stop the snapshots, create a new RAID 1/0 (2+2) RAID group, create new LUNs on the new RAID group, and migrate the RLP to the new LUNs.


Answer : A

You are planning a CIFS DR solution with an EMC VNX for File. The customer wants to use LACP (Link Aggregation Control Protocol) on the Data Movers to provide additional network redundancy for the solution.
What do you advise the customer regarding Data Mover interfaces and CIFS servers for the DR solution?

  • A. Identical interface names must be used on the source and destination VNX systems.
  • B. Identical interface IP addressing is required for the source and destination VNX systems.
  • C. The CIFS server interface is an object that gets replicated with the Virtual Data Mover.
  • D. The Virtual Data Mover will use any available interface on the Data Mover for the CIFS server.


Answer : A

Answer : B

A customer is running a cluster of ESX v4.x servers accessing a VNX LUN with a very large number of virtual machines. They are experiencing intermittent transaction acknowledgement delays. What would you recommend to the customer to lessen these delays?

  • A. Upgrade to VMFS-5 and utilize hardware assisted locking
  • B. Upgrade to vSphere 5 and utilize Block Zeroing
  • C. Upgrade to VMFS-5 and utilize Full Copy
  • D. Upgrade to vSphere 5 and utilize Thin Provisioning Stun


Answer : A

A System Administrator is configuring Data Mover interfaces. They want to keep the same
IP addresses on both sites, but also want to reduce the risk of having duplicate IPs on the same network.
How can this be accomplished?

  • A. The non-production site interface must be manually configured to be off-line. During a failover, the interface must be manually configured to be on-line.
  • B. The non-production site interface must be manually configured to be off-line. During a failover, the interface will automatically go on-line.
  • C. There is no need for manual manipulation of the interfaces during a failover operation.
  • D. Interfaces on both sites can be up but DNS cache must be flushed during a failover.


Answer : A
