Which CLI command will show the cleaning status on an EMC Data Domain system?

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?

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?

In which path location are Autosupport logs stored on an EMC Data Domain system?

You are responsible for capacity planning in an EMC Data Domain environment. While monitoring
space usage over a series of weeks, you notice a sudden increase in space consumption. The
new rate of consumption will require additional capacity.
What is the most likely cause?

A customer’s EMC Data Domain system reports a global compression ratio of 7.8x. This does not
meet the customer’s expectations.
What can be done to increase the data reduction ratio?

An EMC Data Domain system has been installed at a customer’s site for several months and has
reached steady state. At which threshold percent does capacity reach the point where action
should be taken to make more free space available?

When monitoring EMC Data Domain systems, an administrator sees the System Manager File
System Summary showing a compression factor of 20x. How is the equivalent value shown in the
“Reduction%” column?

What is a benefit of snapshots on an EMC Data Domain system?

On an EMC Data Domain system, what is the role of file system cleaning?
