  B. rd=bkp001:/dd01

  C. rd=server_A:/sn_A

  D. rd=dd01:/bkp001

  Correct Answer: A

• Question 55:

  A customer is implementing an EMC Data Domain system in their EMC NetWorker environment using CIFS as illustrated in the exhibit.

  

  A CIFS share named "bkp001" has been created on the Data Domain system. How should the backup device be configured in NetWorker?

  A. rd=sn_A:\\dd01\bkp001

  B. rd=dd01:/bkp001

  C. rd=server_A:\\dd01\bkp001

• Question 56:

  An EMC NetWorker customer is implementing a new EMC Data Domain system in their environment.

  Backup data will be transferred over a private IP network. The customer plans on using three different NetWorker pools with different retention periods.

  Which configuration is required?

  A. Set up multiple retention periods

  B. Create one AFTD for each pool

  C. Configure multiplexing across pools

  D. Avoid mixing different types of data in the same pool

  Correct Answer: B

• Question 57:

  When configuring backups to an EMC Data Domain system using VTL, what is a backup software recommendation?

  B. Decrease parallelism

  C. Increase target sessions

  D. Set target sessions to "1"

  Correct Answer: A

• Question 58:

  A customer implemented an EMC Data Domain system in a Microsoft Windows environment two months ago.

  The Data Domain system was added to the Active Directory domain and backups ran normally until now.

  The backup administrator is trying to access the CIFS share on the Data Domain system from the Windows storage node and is getting an access denied message.

  What is a possible cause?

  A. Privileges for the user account used by the Data Domain system were removed

  B. Time difference between the Data Domain system and the Active Directory server is less than two minutes

  C. Replication services on the Data Domain system are stopped

  D. Cleaning activities have been pending on the Data Domain system for more than one week

  Correct Answer: A

• Question 59:

  A customer implemented an EMC Data Domain system in a Microsoft Windows environment two months ago.

  The Data Domain system was added to the Active Directory domain and backups ran normally until now.

  The backup administrator is trying to access the CIFS share on the Data Domain system from the Windows storage node and is getting an access denied message.

  What is a possible cause?

  A. Data Domain system should be reconfigured for Active Directory support

  B. Time on the Data Domain system is more than five minutes apart from the Active Directory server

  C. Replication services on the Data Domain system are stopped

  D. Cleaning activities have been pending on the Data Domain system for more than one week

  Correct Answer: B

• Question 60:

  A customer is deploying an EMC Data Domain system as a target for backups in their EMC NetWorker environment and a repository for UNIX log files. The NetWorker Storage Node is running Linux. The storage node, UNIX servers, and Data Domain system are all connected to a private backup network through 1 Gb/ s Ethernet.

  Which storage protocol can be used for both functions?

  A. NFS

  B. CIFS

  C. DD Boost

  D. VTL

  Correct Answer: A
