• Question 141:

  What is the default file system type when creating a File System on a VNX?

  A. uxfs
  B. ckpt
  C. rawfs
  D. mgfs
  B. ckpt

• Question 142:

  An implementation engineer installs a DR solution to protect ten CIFS shares at site A. VNX Replicator will be used to replicate the shares from Site A to Site B. How many VDMs should be contained in this DR solution for maximum portability?

  A. 10
  B. 2
  C. 5
  D. 20

• Question 143:

  A customer has a production CLARiiON replicating to a secondary CLARiiON at a remote site using MirrorView/S. The customer wants to upgrade to new EMC VNX, but due to cost constraints, they can only upgrade one of the CLARiiON arrays at this time.

  How do you advise the customer?

  A. A mirror relationship cannot exist between CLARiiON and VNX LUNs.
  B. Replication between faster ports and slower ports is not supported.
  C. Storage pool LUNs cannot mirror to RAID group LUNs.
  D. VNX can only replicate to other VNX arrays.
  A. A mirror relationship cannot exist between CLARiiON and VNX LUNs.

• Question 144:

  A customer configures replication between two Data Movers for their VDM environment. The primary Data Mover has one 1 Gb copper ethernet port and the destination Data Mover has one 10 Gb optical network port. The customer reports replication is not performing as expected and requests your assistance. What is the most likely cause of this replication issue?

  A. The interface on the Data Movers has a duplex mismatch.
  B. The interface speeds do not match on both Data Movers.
  C. The interface names do not match on both Data Movers.
  D. The interface media do not match between Data Movers.
  A. The interface on the Data Movers has a duplex mismatch.

• Question 145:

  A customer wants to reduce the performance impact that Incremental SAN Copy (ISC) has on their source LUN.

  They plan to use a clone between the current source and destination LUN, and then use the fractured clone as the new ISC source LUN. The source LUN performs 400, 8 KB random I/O per second, with a 3:1 read/write ratio. The source

  LUN is 512 GB in size, and the clone will be fractured for five minutes.

  How much data will be copied to the destination LUN?

  A. 937.5 MB
  B. 3,750 MB
  C. 7,500 MB
  D. 14,750 MB
  C. 7,500 MB

• Question 146:

  Which RecoverPoint/SE volume type stores information about the cluster and must be accessible by all RPAs?

  A. Repository
  B. Copy journal
  C. Production journal
  D. All volumes in the replication set
  A. Repository

• Question 147:

  Which RecoverPoint feature allows multiple RPAs to provide replication processing for a single Consistency Group?

  A. Distributed Consistency Groups
  B. Consolidated Snapshots
  C. Bookmarks
  D. Synchronous Replication
  A. Distributed Consistency Groups

• Question 148:

  A corporation has configured high available CIFS shares using VDMs and VNX Replicator. During testing, the VDM and user file systems switch over successfully. However, 30 minutes later the Windows clients still cannot access their shares.

  What is the most likely cause of this problem?

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

• Question 149:

  A customer has an existing DR solution using SRDF between Symmetrix at their source and backup sites. TimeFinder Clones are also used at the backup site. A new VNX is installed at the backup site. The customer tries to use Incremental SAN Copy to copy data updates from the TimeFinder Clone to live web server LUNs on the VNX. The customer reports they are not able to configure the SAN Copy session. Why does the customer need to rework this solution?

  A. The source for Incremental SAN Copy must be a TimeFinder BCV, and the server I/O needs to be stopped.
  B. The source for Incremental SAN Copy must be on the VNX, and the server I/O needs to be stopped.
  C. The source for Incremental SAN Copy must be on the source Symmetrix, and TimeFinder Snapshot needs to be used.
  D. The source for Incremental SAN Copy must be on the VNX, and the data needs to be pushed.
  B. The source for Incremental SAN Copy must be on the VNX, and the server I/O needs to be stopped.

• Question 150:

  What drives the storage sizing requirements for VDI?

  A. desktop/drive density
  B. desktop/drive capacity
  C. desktop/drive type
  D. desktop/drive rpm
  A. desktop/drive density
