• Question 94:

  Click on the calculator icon in the upper left corner.

  An EMC Avamar customer has an Avamar server with four 3.9 TB nodes. They are planning to add a new client to backup to this server. This client has 4 GB of RAM and two file systems. The first file system has 3 million files consuming .75

  TB of space. The second file system contains 5 million files consuming 1 TB of space.

  The customer wants to establish a benchmark for the client's backups in order to determine if the client cache files need tuning. Based on typical performance statistics, how many hours is the steady state backup expected to run?

  A. 3
  B. 4
  C. 5
  D. 8
  D. 8

• Question 95:

  Click on the calculator icon in the upper left corner.

  A customer has an EMC Avamar system with four storage nodes. The backup window is 10 hours and the maintenance schedule is set to the default lengths. The current backup ingest rate averages 1 GB/node/hr over the duration of the backup window.

  Additional clients are being added to the Avamar system. The client data and retention will increase the Avamar GSAN capacity to 50%. Which average data ingest rate would allow the Avamar system to remain at steady state with the new clients?

  A. 2 GB/node/hour
  B. 4 GB/node/hour
  C. 8 GB/node/hour
  D. 16 GB/node/hour
  A. 2 GB/node/hour

• Question 96:

  A customer has an EMC Avamar server integrated with a Data Domain system as a backup solution. They would like to use encryption for the backups that are directed to the Data Domain system. What should you advise the customer?

  A. Enable encryption-at-rest only on the Data Domain system.
  B. Enable in-flight encryption between the client and the Data Domain.
  C. Neither in-flight encryption nor encryption-at-rest are supported.
  D. Both in-flight encryption and encryption-at-rest are supported.
  A. Enable encryption-at-rest only on the Data Domain system.

• Question 97:

  A backup administrator has configured a Dell EMC Data Domain to be used for Dell EMC Avamar storage. The administrator has configured a quota with a soft limit of 500 GB for the Mtree associated with the Avamar server. What should the administrator expect to see when a client with 501 GB of highly redundant data is backed up to the Data Domain?

  A. A warning in the Avamar interface only
  B. Warnings in the Data Domain and Avamar interfaces
  C. Backup will complete with an exception.
  D. A warning in the Data Domain interface only
  B. Warnings in the Data Domain and Avamar interfaces

• Question 98:

  A customer has an EMC Avamar system with a Data Domain device on its back-end. The customer has decided to remove the Data Domain device from its current location and install the device in another location. They want to integrate the Data Domain device into their current backup solution with NetWorker using DD Boost. What is a best practice to remove the Data Domain device from the Avamar system?

  A. Use Data Domain shredding to remove all data from the device
  B. Remove all backups on the Avamar system and allow the checkpoints to roll off
  C. Remove all backups on the Avamar system and remove all checkpoints
  D. Move all clients to MC_RETIRED and allow all data to roll off the Avamar system
  B. Remove all backups on the Avamar system and allow the checkpoints to roll off

• Question 99:

  You have been tasked with installing a 1 TB Avamar AVE server in an ESX environment for a new customer. The customer has thick provisioned the correct amount of LUNs with the correct sizing. The Performance Assurance Tool (PAT) has been loaded on the ESX environment and ran for 24 hours. The results come back and the test did not pass the requirements for an AVE installation.

  The customer says the test was not valid because there was a high load on their ESX environment at the same time the test was running. They want to run the test again. Should the tests be run again without any changes to the environment?

  A. No. The PAT simulates I/O performance of an AVE server and caused the high load.
  B. No. The PAT can only be run once on an environment.
  C. Yes. The extra load on the server skewed the results.
  D. Yes. The PAT tool will take the high load into consideration on the second run.
  A. No. The PAT simulates I/O performance of an AVE server and caused the high load.

• Question 100:

  In order to restore from an online backup with archive logs, which prefix should they look for when choosing a backup file?

  A. hl
  B. c
