EMC E20-385 Online Questions & Answers

• Question 81:

  An organization currently writes backups to an EMC Data Domain system and then creates encrypted copies of their backups on tapes. These tapes are then shipped to a third-party offsite vault. They are now planning to deploy a second Data Domain system to a secure data center at their corporate headquarters as a replication target to replace the use of the offsite tapes. The two sites are connected through the Internet.

  Where should encryption be applied on the Data Domain systems to ensure a similar level of data security as achieved by their current process?

  A. Encrypt the replication context
  B. Encrypt the data at rest
  C. Encrypt the data at rest and the replication context
  D. Encryption is not required
  A. Encrypt the replication context

• Question 82:

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

• Question 83:

  You are installing an EMC Data Domain system with two expansion shelves in a customer- provided rack. When cabling the controller to the shelves, where does the expansion port on the last shelf get connected?

  A. Expansion port is left un-cabled
  B. Host port on the controller
  C. Host port on the other expansion shelf
  D. Expansion port on the controller
  A. Expansion port is left un-cabled

• Question 84:

  An organization has 3000 GB of file system data with a daily change rate of 10%. Assume the first backup reduces by a factor of 3 (3x), daily incremental backups reduce by a factor of 10 (10x), and subsequent full backups reduce by a factor of 30 (30x).

  A. rd=sn_A:\\dd01\bkp001
  B. rd=dd01:/bkp001
  C. rd=server_A:\\dd01\bkp001
  D. \\dd01\bkp001
  A. rd=sn_A:\\dd01\bkp001

  C. AFTD
  D. Storage Unit
  A. File

• Question 89:
