Question: 18

An EMC customer uses an Avamar server with an integrated Data Domain system at their data center to protect a number of Microsoft Exchange servers and Oracle databases. The customer also has several remote offices. Each remote office has a single node Avamar server backing up the local clients. All backups from the remote offices are replicated to the data center.
Following an acquisition, the company needs to add 10 new remote offices to its Avamar data protection solution. Three of these offices host Oracle databases with approximately 8 TB in size. All backup data from the remote sites need to be replicated to the primary data center while keeping the data traffic on the WAN to a minimum. They also want to maintain centralized management and reporting capabilities. Based on EMC best practices, how can this be accomplished?

A. Deploy an Avamar server in every office and an integrated Data Domain system in each of the three remote offices with Oracle databases.
B. Deploy an Avamar server in every office, replicating to the central data center.
C. Deploy Avamar clients on every client to be protected, sending backup data to a central Avamar server.
D. Deploy an Avamar server in every office, and Accelerator nodes to back up the large databases to Data Domain systems at the primary data center.
