  What is the correct method to securely delete the backups from the Avamar server with minimal interference to existing backups from other clients?

• Question 75:

  An EMC NetWorker customer is backing up all file system clients to a deduplication node. Over the past year, new file system clients have been added to the backup environment. The customer wants to add another Avamar server and

  distribute the backup workload by having some of the larger clients changed to back up to the new deduplication node.

  What is the impact of this decision?

  A. Clients backing up to the new deduplication node must run an initial full backup
  B. Existing backups for these clients must be deleted from the old deduplication node
  C. New client resources must be created on the NetWorker server
  D. Clients must be deleted from the old deduplication node
  A. Clients backing up to the new deduplication node must run an initial full backup

• Question 77:

  A customer wants to maximize their tapeout throughput with Avamar Tapeout (ATO) by using concurrent staging servers. The servers consist of one Microsoft Windows-based and one UNIX-based.

  were started concurrently.

  What is the expected outcome?

  A. Tapeout fails because concurrent tapeout activities are not supported with a single environment file
  B. Tapeout throughput is double that of using a single staging server
  C. Tapeout fails because a single environment file cannot be configured for two staging server types
  D. Tapeout succeeds because two batch profiles can access a single environment file concurrently
  A. Tapeout fails because concurrent tapeout activities are not supported with a single environment file

• Question 78:

  A. NDMP backups to Avamar do not use a file cache during the backup process.
  B. Demand paging caches for NDMP backups are self tuning and do not need adjustment.
  C. The file cache size may be increased if the NDMP accelerator has 8 GB of RAM or more.
  D. The file cache on the NAS device may be tuned to accommodate more files.
  A. NDMP backups to Avamar do not use a file cache during the backup process.

• Question 79:
