Veritas NetBackup 8.3 and NetBackup Appliances 3.3 Administrator — Question 28

A Windows policy protects over 100 servers using the directive ALL_LOCAL_DRIVES. The backup window for this policy is a two-hour window that is unused by any other policy. When the jobs run, each server has no more than ten paths, and the overall performance of the disk storage unit is degraded.
Which setting should the administrator modify to ensure only ten jobs write concurrently to the disk storage unit during the backup window?

Answer options

• A. set the Allow multiple data streams policy attribute
• B. enable the Limit Jobs per policy attribute
• C. set the Maximum jobs per client host property
• D. enable multiplexing for the storage unit and set the value

Correct answer: D

Explanation

The correct answer is D, as enabling multiplexing allows multiple backup streams to be combined, effectively controlling the number of concurrent jobs that can write to the disk storage unit. The other options do not specifically limit the number of jobs writing concurrently to the storage unit, which is essential to prevent performance degradation.
