QUESTION NO: 4
A backup administrator has enabled the Retention Lock feature on a Dell EMC Data Domain system.
They notice increased file system utilization over time and upon investigation they discover the expired files are still present on the Data Domain system.
What could be the possible reason for this situation?
A. A time retention expiration date for an archivefile was set below the minimum retention period
B. Retention lock feature was disabled before expiration date
C. Archiving application was not set to delete the file after expiration
D. File system cleaning was not running as per the schedule
Answer: A

QUESTION NO: 5
Which functionality is recommended by Dell EMC to be disabled on backup software when configuring Dell EMC Data Domain VTL?
A. Multiplexing
B. Multithreading
C. Parallelism
D. Target Session
Answer: A
Explanation:
Multiplexing, compression, and encryption of backup data were introduced to provide read parallelism as well as enhanced security and performance during backups. Backing up to a Data
Domain system is inherently more secure than tape, and does not suffer performance degradation due to slow backup streams. Thus the recommendation is to disable any of these features when using a Data Domain system as the target for RMAN.
