• Question 131:

  A client is performing a file system backup to an Avamar 7.0 server. During the hashing process, it determines that a file hash is not located in any of the cache pages loaded in RAM, but is found in the champion list. What will happen as a result of this?

• Question 132:

  An EMC customer is looking for options to back up their smaller remote sites with easy remote management, so they want to use Avamar Virtual Edition (AVE). Before installing ESX hardware at the remote sites they want to do a proof of

  concept using the existing ESX 4.1 server that they have at the data center.

  They provisioned 2 TB of virtual disks using VMAX thick provisioning with RAID 5 protection and zeroed out all blocks using eager zeroing. They tested the backup of three servers and do not see an improvement.

  According to best practices, what should the customer have done to avoid performance issues?

  A. Use RAID 10 for the virtual devices.
  B. Use ESX 5.0i to host the AVE server.
  C. Use thin devices for the virtual devices.
  D. Use lazy zeroing to zero out all blocks.
  A. Use RAID 10 for the virtual devices.

• Question 133:

  The backup administrator with a large Hyper-V environment has been asked to exclude a group of VMs from regularly scheduled backups. Which is the best option to satisfy that request?

  A. Add --excludelist=vm1,vm2 etc to the avhypervvss.cmd file in the Hyper-V server Avamar client /var directory.
  B. Add the VMs as excludes in the Dataset policy for the Group.
  C. Add the VMs to the avtar.cmd file in the Hyper-V server Avamar client /var directory.
  D. Add --excludelist=vmname to the avhypervvss.cmd file in the Avamar Client /var directory on the VM.
  A. Add --excludelist=vm1,vm2 etc to the avhypervvss.cmd file in the Hyper-V server Avamar client /var directory.

• Question 134:

  An EMC customer has Windows virtual machines running in a VMware vSphere environment protected by an Avamar multi-node server using guest level backups. They are concerned with the RTO of these virtual machines. Which method would provide the lowest RTO?

  A. Deploy a template of the OS that is preinstalled with the Avamar agent and restore selected data.
  B. Capture VSS backups of the server and boot from the recovery ISO to restore the server.
  C. Use an Avamar VMware Image Proxy and restore the VM with CBT enabled.
  D. Use an Avamar VMware Image Proxy to perform file level restores.
  A. Deploy a template of the OS that is preinstalled with the Avamar agent and restore selected data.

• Question 135:

  You are adding a deduplication node to a customer's EMC NetWorker environment. The NetWorker clients currently back up to tape and perform full backups on Sunday and incremental backups on the other days of the week. In the new solution, all clients will back up to the deduplication node. The speed of recovery and higher deduplication rates are important to the customer. Which NetWorker schedule is recommended?

  A. Full backups on Sunday and incremental backups on other days of the week
  B. Incremental backups every day
  C. Full backups every day
  D. Initial full backup followed by incremental backups
  C. Full backups every day

• Question 136:

  A customer has installed EMC NetWorker with Avamar as its device for deduplication disk storage. The administrator is setting up a NetWorker client for a Microsoft Windows 2008 SP2 server to backup to their Avamar system. Which process is responsible for the bulk of the deduplication processing on the client?

  A. nsravtar
  B. nsravamar
  C. nsradmin
  D. save
  A. nsravtar

• Question 137:

  An EMC Avamar customer has a backup that is running longer than expected. EMC Support is asking for more logging information from the client. What is the recommended method for providing this information?

  A. Create an avtar.cmd file in the Avamar client directory and place the 璬ebug flag in the file
  B. Insert the 璬ebug flag in the .avamar file in the Home directory on the client and restart the backup
  C. Execute a dumpmaintlogs command and send it to EMC Support
  D. Execute getlogs and send to EMC Support
  A. Create an avtar.cmd file in the Avamar client directory and place the 璬ebug flag in the file

• Question 138:

  A customer has an EMC Avamar system backing up a Celerra running DART 6.0 using a single 36 GB NDMP Accelerator Node. They are also going to back up a VNX OE 7.0 system using the same NDMP Accelerator. Each NAS device has

  four volumes configured on it. Backups will be configured on the Avamar system for both NAS storage devices to start at the same time.

  What will occur when the NDMP backups start using default settings?

  A. Both backups will start with two active streams each
  B. One NAS device will start its backup with four streams, the other will queue
  C. One NAS device will start its backup with one stream, the other will queue
  D. Both backups will start with one stream each
  B. One NAS device will start its backup with four streams, the other will queue

• Question 139:

  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
  A. Maintenance schedule should be shifted by 12 hours

• Question 140:

  A new EMC Avamar customer is planning to have a multi-node Avamar server replicate to an offsite multi-node Avamar server. Because their data is extremely sensitive, they are concerned about the security of the backup environment.

  The customer is planning to encrypt all network transmissions. They also want to use encryption-at-rest on the primary Avamar backup server to provide an additional level of data security for their stored backup data. What is an expected outcome of this configuration?

  A. Encryption between two Avamar servers is only available at AES-128
  B. Replicated data will be stored in an encrypted format on the replication target server
  C. Replicated data will be stored in an unencrypted format on the replication target server
  D. Encryption-at-rest is performed on the clients and will negatively impact performance of the client hosts
  C. Replicated data will be stored in an unencrypted format on the replication target server
