• Question 161:

  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.

  Correct Answer: A

• Question 162:

  Refer to Scenario 6.

  

  The customer has decided to add a second Data Domain server to HQ to meet database backup growth for Microsoft SharePoint which consists of many small databases. The customer advises you that HQ now has two Data Domain (DD)

  servers paired to the single Avamar Gen4 server.

  The disaster site has an integrated Avamar server with an expandable Data Domain server. However, the Avamar server is a single-node Gen4 that cannot be further expanded and is at capacity.

  What must be done at the disaster recovery site to support replication from the HQ Avamar/DD system?

  A. Migrate the Avamar server to a new multi-node server

  B. Expand the DD system and migrate the Avamar server to a new multi-node server

  C. Expand the DD system to match the second DD server at HQ

  D. Expand the DD system and install a second Avamar single-node

  Correct Answer: B

• Question 163:

  Refer to Scenario 9.

  B. catman

  C. sysdb

  D. root

  Correct Answer: A

• Question 164:

  Refer to Scenario 10.

  

  The customer has raised a concern about the RTO of their Windows servers in their development environment. Which backup method would provide the lowest RTO?

  A. Deploy a template of the O/S that is preinstalled with the Avamar agent and perform restores using system state backups

  B. Capture VSS backups of the server and boot from the recovery ISO to restore the server

  C. Use an Avamar VMware Image Proxy set to Windows and restore the VM with CBT enabled

  D. Use an Avamar VMware Image Proxy set to Windows/Linux and restore the VM with CBT enabled

  Correct Answer: A

• Question 165:

  Refer to Scenario 2.

  

  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 done?

  A. `Server DB2' is SPARC. Hash calculations take longer than an X86; increase CPU power.

  B. File servers are taking too long. Back up `Server DB2' first and then backup `Server DB1' and file servers.

  C. `Server DB1' is taking too long to back up. Back up `Server DB2' first, `Server DB1' next, and then all file servers.

  D. `Server DB2' is SPARC. Increase the amount of RAM to hold more hash cache.

  Correct Answer: A

• Question 166:

  Refer to Scenario 6.

  

  The customer needs to add another 2 TB of database data into the replicated environment. The disaster recovery Data Domain system is expandable but the HQ Data Domain system is full. Which replication solution supports the new capacity requirement at the least cost?

  A. Add an additional Avamar server to both sites and integrate with the HQ DD system

  B. No change in DD capacity is needed at the HQ site

  C. Add an additional DD server to the Avamar/DD system at the HQ site

  D. Add an additional DD system to both sites and integrate with the HQ Avamar system

  Correct Answer: C

• Question 167:

  Refer to Scenario 2.

  

  An EMC Avamar backup administrator has asked for a plan that allows all servers to complete initial backups over the next two nights. Which initial backup plan meets all customer constraints and accommodates average Avamar data scan rates?

  A. Initiate file server backups first, database server backups next with multiple RMAN scripts, and then all remaining backups

  B. Initiate all backups at the start of the Saturday backup window; database server backups need the --parallel flag

  C. Initiate file server backups first followed by database servers next

  D. Initiate database server backups on Saturday and file server backups on Sunday

  Correct Answer: A

• Question 168:

  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 of individual messages. The Exchange VSS agent has been installed with the GLR option enabled and the host has been rebooted.What else needs to be done to allow granular level recoveries?

  A. Install the Microsoft MAPI-CDO objects on the Exchange server and configure the Avamar backup user

  B. Configure the Avamar backup user and configure a dataset for granular level backups

  C. Install the Microsoft MAPI-CDO objects on the Exchange server and configure the Exchange Recovery Storage Group

  D. Configure a dataset for granular level backups and install the Microsoft MAPI-CDO objects on the Exchange server

  Correct Answer: A

• Question 169:

  An EMC customer has a need to backup several remote client machines to a central Co-Location data center. They have purchased an EMC Avamar to backup their desktop/laptop (DTLT) client data. The DTLT clients backing up to the Avamar will span three time zones and management of the Avamar server will take place from the same time zone as the remote data center.

  If the customer has a need to start DTLT backups at 10 A.M. daily in their local time zone, which changes should be made in the Avamar environment to ensure a healthy Avamar system?

  A. Maintenance schedule should be shifted by 12 hours

  B. Time zone of the storage nodes should be changed from UTC

  C. Set Avamar time zone to match the DTLT machines

  D. Schedule the backups to occur at the end of the blackout window

  Correct Answer: A

• Question 170:

  An EMC Avamar customer is using VADP to protect Microsoft Windows virtual machines (VMs) at an image level. They want to have the ability to perform file level recovery of select files. An Avamar Windows FLR proxy will be deployed to

  Where should the FLR proxy be deployed for optimal backup and restore performance?

  A. LAN proximity to the ESX datastore the VMs reside on

  B. LAN proximity to the proxy backup servers

  C. LAN proximity to the Avamar server
