E20-891 Question #95: Real Exam Question with Answer & Explanation

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 now wants to replicate all backup data to a secondary site for disaster recovery reasons. At a minimum, how many systems need to be deployed at the secondary site to satisfy this request?
