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

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

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

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