• Question 211:

  An EMC Avamar customer has a requirement to backup SQL databases with multiple filegroups. As a test of data recovery procedures, the backups need to be restored to a different server. Which restore method should be used?

  A. Redirected restore using a SQL backup format file
  B. Redirected restore from a differential SQL backup
  C. Redirected restore using a SQL transaction log file
  D. Redirected restore from an incremental SQL backup

• Question 212:

  Refer to Scenario 2.

  

  A 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, one node will meet the RTO. No additional switches are needed beyond a simple recovery.
  C. Using a recovery rate of 37.5 GB/hr/node, three nodes will meet the RTO. No additional switches are needed beyond a simple 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.

  A. Perform a file system recovery of the f-0 file and use SQL Server Manager to manually adjust the layout.
  B. Ensure the recovery server storage is provisioned to match the backup prior to initiating the recovery.
  C. Perform a database redirected restore with a tail-log backup to the other instance.
  D. Perform the recovery as a database using SQL Server Manager to adjust the layout to match that of the recovery server.
  A. Perform a file system recovery of the f-0 file and use SQL Server Manager to manually adjust the layout.

  A. A Level 0 backup had to be performed prior to a Level 1 backup being run.
  B. The database is not configured to allow Block Change Tracking.
  C. The amount of data changed in the database is too large for a Level 1 backup to be performed.
  D. Oracle does not support Level 1 backups after a full backup.
