  C. 3
  D. 4
  A. 1

• Question 126:

  A company has two locations and wants to implement a DR solution for their Exchange databases. The following requirements factor into their SLA:

  -Multi-application support.

  -Continuous replication with zero data loss.

  -Minimal replication load on application host.

  -

  Support a distance of 60 km.

  Which DR solution meets the SLA requirements?

  A. MirrorView/A
  B. DAG
  C. Sync-API
  D. RecoverPoint/S

  B. ntfs
  C. rawfs
  D. ckpt
  B. ntfs

• Question 128:

  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 stops functioning. What is the most likely reason for the Exchange failure?

  A. Replication Manager is unable to truncate log files.
  B. Replication Manager can only snapshot powered off VMs.
  C. Replication Manager is compatible with RDMs, not VMDKs.
  D. Replication Manager is not compatible with VMFS version 5.
  A. Replication Manager is unable to truncate log files.

  A. A
  B. B
  C. C
  D. D
  B. B

• Question 130:

  A customer plans to move a performance-sensitive application to a new EMC VNX with all SAS drives. The application will reside on an NFS export, and the customer requires the file system provide consistent performance. The customer

  also needs to create additional CIFS shares, which do not share the same performance requirement.

  How should both sets of file systems be created?

  A. Place four dvols in a user-defined pool for the NFS-exported file systems and let AVM manage the CIFS file systems with system-defined pools.
  B. Place five dvols in a user-defined mapped pool for the NFS-exported file systems and let AVM manage CIFS file systems with system-defined pools.
  C. Place four dvols in a system-defined pool for the NFS-exported file systems and let AVM manage the CIFS file systems with user-defined pools.
  D. Place five dvols in a system-defined mapped pool for the NFS-exported file systems and let AVM manage the CIFS file systems with user-defined pools.
  A. Place four dvols in a user-defined pool for the NFS-exported file systems and let AVM manage the CIFS file systems with system-defined pools.
