Scenario 6
A customer recently implemented an EMC Avamar solution in their primary data center. The
environment consists of several Microsoft applications, including Microsoft SharePoint, Exchange,
and SQL. An EMC Data Domain system was also deployed behind Avamar as the backup
destination for these applications. There are also several file system clients that have been
configured to back up directly to the Avamar server.
One Avamar server and two Data Domain systems have been deployed to support this
configuration. The Avamar server is operating close to full capacity and there is no room for

expansion since it is already fully provisioned with the maximum number of nodes. The Data
Domain systems have plenty of capacity left; each system is currently at 35% of utilization.
Refer to Scenario 6.
The customer noticed that while backing up the Microsoft Exchange clients, a significant amount
of data is being stored on the Avamar server. The Exchange clients are configured to send their
data to the Data Domain system.
What is an explanation for this behavior?

A.
Exchange log files are always stored on the Avamar server

B.
Data Domain system has run out of capacity and backup data is being redirected to the Avamar
server

C.
Avamar server is caching the backup data and then sending it to Data Domain system

D.
Data is being reconstructed on the Avamar server so that it can be replicated
