• Question 295:

  A customer wants to know why their backup performance to an EMC Avamar multi-node server has decreased. Initially they were seeing an ingest rate of approximately 5 to 7 GB/hr/node. Recently they estimated that the ingest rate has slowed to around 3 to 5 GB/hr/node. What is a probable cause for the decrease in the average ingest rate?

  A. Garbage collection is not running causing new stripes to be created
  B. HFS check has found errors and has not been completing successfully
  C. A large number of backups have expired causing new, relatively empty stripes to be created
  D. Stripes contain more data and steady state has been achieved
  D. Stripes contain more data and steady state has been achieved

  A. Asset Management and Planning Appliance
  B. Data Deduplication Assessment
  C. EMC Backup Assessment
  D. File System Assessment
  C. EMC Backup Assessment

• Question 300:

  Refer to Scenario .

  A customer is looking to modernize their backup infrastructure. The current environment consists of a single centralized data center and several remote sites. The centralized data center hosts all core services and applications. The remote

  office primarily consists of sales personnel with 4000 use-North America, 500 in Europe, and 300 in Asia using file servers.

  The current backup environment at the primary site uses CommVault backing up to a Fibre Channel tape library that contains four ITO-4 tape drives. Currently they are backing up a number of file servers as well as several databases that

  have average change rates of 7% daily Remote office backups are currently performed by having users copy files to regional file servers that are then backed up to tape.

  In the past few months, the customer has experienced problems with getting backups to finish within their defined windows as well as issues with the tape library hardware. They now have concerns about gaps in their backup coverage as

  well as the reliability of the tape media. In addition, an internal audit shows a large amount of user-generated data is unprotected on remote user laptops.

  The customer is looking for a common platform to standardize their backups. They want a solution which allows for a centralized infrastructure so -they do not need to rely on remote resources to address hardware and software issues. The

  other goal is to move away from tape to a more reliable disk-based solution.

  The customer is evaluating EMC Avamar as a possible solution to backup their remote users. They are estimating that each machine will take approximately 10 minutes to backup. They would like all backups to complete in 8 hours.

  What is the minimum number of storage nodes needed to support the necessary connections to complete the backups of the North American system in the defined window?

  A. 3
  B. 4
  C. 5
  D. 6
  B. 4
