• Question 63:

  Exchange 2010 is installed on a virtual machine using VMDK files. Replication Manager is being used to take snapshots of the virtual machine files and back them up to disk. After a few weeks, the Exchange server backups stop functioning. What is the most likely reason for this failure?

  A. Replication Manager agent service has stopped
  B. Replication Manager can only snapshot powered off VMs
  C. Replication Manager is not compatible with VMFS version 5
  D. Replication Manager agent is installed on each DAG server
  A. Replication Manager agent service has stopped

• Question 64:

  Which type of RecoverPoint/SE Image Access allows the hosts to have direct access to the replica volumes, but pauses the distribution of snapshots from the journal to storage?

  A. Logged Access (physical)
  B. Virtual Access
  C. Direct Access
  D. Marking Access
  A. Logged Access (physical)

• Question 65:

  A customer wants to implement file system replication between two EMC VNX. The source production file system contains data from a sequential workload that resides in a pool comprised of 2 TB NL-SAS drives. Due to cost concerns, the destination file system and SavVol volumes will also be NL-SAS and share spindles with user LUNs for another application. What should you tell the customer about this configuration?

  A. The configuration goes against EMC best practices because it shares LUNs with user applications.
  B. NL-SAS is adequate if the source file system is on NL-SAS and contains a sequential application.
  C. When using VNX Replicator, only SAS drives should be used for Replication SavVol Volumes.
  D. The destination file system can be used as a source for cascaded replication with no impact to performance.
  A. The configuration goes against EMC best practices because it shares LUNs with user applications.

• Question 66:

  An EMC VNX with EMC FAST Suite will be used as block storage for four Exchange 2010 servers. The Exchange servers will be used as mailbox and archive servers. The VNX has the following disks in two DAEs:

  -Five 200 GB Flash drives

  -Fifteen 600 GB SAS drives

  -

  Ten 2 TB NL-SAS drives

  The customer wants to implement auto-tiering. What do you advise the customer?

  A. Retrieving an archived email will force moving the whole Archive mailbox to EFD disks.
  B. Storage tiering is not recommended because of Exchange 2010 BDM operations.
  C. Auto-tiering works only when every disk type group is installed in a separate DAE.
  D. There is no benefit to using auto-tiering with an archive solution.
  B. Storage tiering is not recommended because of Exchange 2010 BDM operations.

• Question 67:

  A customer plans to implement shared vSphere datastores using the NFS protocol in their environment. Their VMware support staff has concerns about their administration of these datastores. What features of vSphere v5 would you discuss with them to address their concerns?

  A. Thick virtual disks can now be created to support failover clustering for certain business critical server environments.
  B. The native networking stack has been upgraded to support Version 4 attributes of the protocol.
  C. The network interface adapter teaming feature has been upgraded to support automated path failover in the event of session timeouts.
  D. This type of datastore implementation has been upgraded to enable automated error correction of vmdk files.
  A. Thick virtual disks can now be created to support failover clustering for certain business critical server environments.

• Question 68:

  A customer has two identically configured Linux hosts (OS version, memory, CPU) attached to the same network. One host is NFS-attached and the other is FC-attached to an EMC VNX. Both the NFS file systems and the SAN LUNs are created from four RAID 5 (4+1) RAID groups. LUNs are not shared between file and block and each host generates the same size I/O.

  The customer reports the FC-attached host is able to achieve much greater throughput than the NFS- attached host. What is the source of the performance difference between the file and block configurations?

  A. FC encapsulation overhead
  B. Host Patch levels
  C. Ethernet Network
  D. NFS version
  C. Ethernet Network

• Question 69:

  A customer wants to deploy an Exchange 2010 farm doing 8,400 IOPS with a R/W ratio of 1/1. The total amount of space needed is 7,500 GB.

  What would you recommend the storage configuration to be?

  A. A pool consisting of five 100 GB eMLC Flash drives, and 30 drives of 300 GB 15K in RAID 5, with FAST-VP enabled
  B. A pool consisting of five 100 GB eMLC Flash drives in RAID 5, and 20 drives of 300 GB 15K in RAID 5, with FAST-VP enabled
  C. A pool consisting of 120 drives of 300 GB 15K, in RAID 5 (4+1)
  D. A pool consisting of 120 drives of 600 GB 15K, in RAID 5 (4+1)
  A. A pool consisting of five 100 GB eMLC Flash drives, and 30 drives of 300 GB 15K in RAID 5, with FAST-VP enabled

• Question 70:

  A corporation has configured highly available CIFS file systems with VDMs. Replication is configured from a primary site to a secondary site. During testing, the VDM and user file systems switchover successfully, but 30 minutes later Windows clients still cannot access their shares. What is the most likely cause of this problem?

  A. VDMs are not configured on the secondary site.
  B. The CIFS service is not running on the secondary site.
  C. Source side file systems are not correctly sized.
  D. Source side VDM Replication licensing is not enabled.
  B. The CIFS service is not running on the secondary site.
