• Question 157:

  A company recently deployed an MS SharePoint Farm that consists of three Web Front End (WFE) servers, three application servers and two database servers. Avamar backup software setup and configuration was completed according to

  EMC best practices. WFE server #1 was designated as "owner" of the backup.

  The company also decided that they need Granular Level Recovery functionality and installed Avamar GLR plug-in and Kroll Ontrack on WFE server #2. Federated backups of this farm were running successfully for the last 30 days.

  One day ago, the SharePoint administrator discovered corruption in the Central Administration content database and is asking to recover individual items using GLR functionality.

  How can the company accomplish this task?

  A. Use a restore of the entire farm to restore the Central Administration content database.
  B. Use the redirected restore option with GLR plugin and Kroll Ontrack to extract required items back to the farm.
  C. Use a GLR restore and MS SQL administration tools to extract required items back to the farm.
  D. Use the redirected restore of the Central Administration content database to alternative farm and extract required items from there.
  A. Use a restore of the entire farm to restore the Central Administration content database.

• Question 158:

  A customer has a newly installed EMC Avamar Gen4S server with three 3.9 TB nodes in their headquarters data center. They are backing up two database servers with 1 TB of small databases each. The customer requires that the servers

  can be restored in six hours.

  The customer's database administrators need to know that they can meet their RTO. In addition, they want to know how to test the throughput rate when recovering all data and how to format the recovery command to guarantee throughput.

  What is a recommendation for testing the throughput rate and recovery?

  A. Using a recovery rate of 75 GB/hr/node, three nodes will meet the RTO. Use --validate for testing of recovery throughput and --allnodes for recoveries.
  B. Using a recovery rate of 37.5 GB/hr/node, two nodes will meet the RTO. Use --validate for testing of recovery throughput and --allnodes for recoveries.
  C. Using a recovery rate of 37.5 GB/hr/node, three nodes will meet the RTO.Use --validate and --sequencenumber for throughput testing and recovery.
  D. Using a recovery rate of 75 GB/hr/node, two nodes will meet the RTO.Use --validate and --sequencenumber for throughput testing and recovery.
  A. Using a recovery rate of 75 GB/hr/node, three nodes will meet the RTO. Use --validate for testing of recovery throughput and --allnodes for recoveries.

• Question 159:

  An EMC customer has an Avamar server integrated with a Data Domain appliance. Their administrator noticed in the Avamar Administrator GUI that the Data Domain status bar icon is showing the Data Domain system as unresponsive. What is the most likely impact of the problem?

  A. Avamar cannot retrieve information from the Data Domain system. However, backups and restores can continue during this condition.
