A company is replicating two specific directories between two EMC Data Domain systems using a 4 Mb/s WAN
connection. What can be done on the Data Domain systems to maximize replication performance?

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

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

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?

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?

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?

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?

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

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 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?
