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 PAT tool will take the high load into consideration on the second run.
• D.Yes. The extra load on the server skewed the results.

A customer set up their EMC Celerra to back up through an Avamar NDMP accelerator node. They are not seeing any increased performance since the initial backup. They have investigated the Celerra and there are no outstanding issues.
What is a potential reason for the poor backup performance?

• A.Data has a low change rate.
• B.The dataset advanced option is blank.
• C.Dataset options are set to Level-0.
• D.Dataset options are set to Level-1.

What is the correct order of operations to prepare an Oracle database for dell EMC Avamar backup in ARCHIVELOG mode?

Correct Answer:

Explanation
Step 1 - Put database in ARCHIEVELOG mode
Step 2 - Shut down database
Step 3 - Start and mount database
Step 4 - Open database for normal operation

A current EMC Avamar customer is backing up the databases of their Microsoft Exchange 2007 environment on a nightly basis using the MS Exchange VSS plug-in. They now want to perform granular level recovery (GLR) of individual messages. The Exchange VSS agent has been installed with the GLR option enabled.
What else needs to be done to allow granular level recoveries?

• A.Install Microsoft MAPI-CDO on the Exchange serverConfigure the Exchange Recovery Storage Group
• B.Install Microsoft MAPI-CDO on the Exchange server Configure the AvamarBackupUserReboot
• C.Configure the AvamarBackupUser Reboot the Exchange server
• D.Configure Exchange Recovery Storage Group Configure AvamarBackupUserReboot

A customer has a newly installed EMC Avamar. They have the following backup clients:
- Oracle database 'Server DB1' with 1 TB of small databases, X86-64 architecture, 8 GB of RAM
- Oracle database 'Server DB2' with 1 TB of small databases, SPARC architecture, 8 GB of RAM
- 60 file servers with 10 - 100 GB of data on each, X86-64 architecture, 4 GB of RAM The backup window is four hours and overtime is not allowed. After kicking off the initial backups, an EMC Avamar backup administrator reports that Server DB1 completed its backup. However, Server DB2 did not.
Given the information provided, what is impacting the backup time and what can be done?

• A.Server DB1 is taking a long time to back up, delaying the other clients. Back up Server DB2 first, Server DB1 next, and then all file servers.
• B.Server DB2 is SPARC. Hash calculations take longer than an X86; increase CPU power.
• C.File servers are taking a long time to back up, delaying the other clients. Back up Server DB2 first and then back up Server DB1 and file servers.
• D.Server DB2 is SPARC. Increase the amount of RAM to hold more hash cache.
