A customer wants to improve the performance of their EMC Data Domain system. After checking
their weekly reports, they notice that on the same day each week, file system performance is
impacted. At first the customer thought the performance issue was caused by full backups that run
on Friday. However, the performance issue is occurring on Tuesday.
What is a possible reason for this behavior?

A.
Cleaning throttle is set to 90
B.
Directory replication is running
C.
File system is in a disabled state
D.
Full database backups are running
The right answer is A.
Found the answer in
https://community.emc.com/docs/DOC-17867
After running through the practice and several trial and error, I’ve got the answer is A. Still dont know the reason tough. I guess this question comes from real cases.
