What is the most likely cause?
A. A new project on the client systems involve high volume of pre-compressed file types
B. Retention period was decreased from 16 weeks to 12 weeks
C. Rate of full backups was changed from twice a week to once a week

In which path location are Autosupport logs stored on an EMC Data Domain system?
A. /ddvar/support
B. /ddvar/log/debug
C. /data/col1/support
D. /data/col1/debug
An EMC Data Domain customer has configured replication of four directories created under the /data/col1/ backup MTree with the following configuration: NFS Exports /data/col1/backup/Engineering /data/col1/backup/Oracle CIFS Shares /data/col1/backup/Operations /data/col1/backup/HR They want to achieve the following:
1.
Move these directories to MTrees
2.
Consolidate the directories, where possible, to minimize the number of MTrees
3.
Create new replication contexts
They do not plan to change the protocols used to access these locations.
Which MTree setup will support this configuration change?
A. Consolidate directories (Engineering and Oracle) to one MTree Consolidate directories (Operations and HR) to one MTree
B. Rename the entire/data/col1/backup MTree to /data/col1/IT
C. Consolidate directories (Engineering, Oracle, and Operations) into a single MTree Convert the HR directory into its own MTree
D. Consolidate all directories into a single MTree

A customer has configured an MTree (/data/col1/departments) on an EMC Data Domain system with two subdirectories configured as Sales and HR. They want to configure replication to replicate only the Sales subdirectory to another Data Domain system. In addition, they do not want to replicate the HR subdirectory.
How can this be accomplished?
A. Move the Sales subdirectory to its own MTree
B. Take a snapshot of the Sales subdirectory and replicate the snapshot
C. Configure directory replication for the subdirectory /data/col1/departments/Sales
D. Perform a fast copy of the subdirectory /data/col1/departments/Sales and replicate the copy

What is the default behavior for the "messages" log file in an EMC Data Domain system?
