D.

Explanation:
Avamar VCB Interoperability Module. The Avamar agent and the interoperability module run on
the Consolidated Backup proxy server to provide the backup services. One backup server can
provide backup services to many ESX server hosts, as long as all machines share the same SAN
(storage area network).
With this approach, users have several advantages. By consolidating backups onto fewer proxy
servers, backup can be simplified and backup licensing costs for VMware environments can be
reduced. VCB reduces the load on the ESX Server during backups, eliminating the need to
manage backup agents in each virtual machine. And, because of its method of transferring data
using the SAN, LAN traffic associated with backup is reduced. With this approach, there is no
direct application integration as is possible with guest backups using Avamar database plug-ins.
Note: Backup proxy server supported on Windows 2003 server only.
