EMC E20-895 Online Questions & Answers

• Question 1:

  An EMC customer is using the Avamar Exchange 2007 plug-in for message level backups on two Microsoft Windows Exchange 2007 environments in an Active Directory Forest. They are deployed in a high availability configuration. The customer wants the ability to successfully backup after a cluster failover. What must be done to achieve a successful backup?

• Question 2:

  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 have provisioned 2 TB of virtual disks using VMAX thin provisioning with RAID 1

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

• Question 3:

  A customer with an existing EMC NetWorker environment has recently added an Avamar system to their environment. Avamar enhanced NDMP backup capabilities will be used to backup Celerra. In addition, the customer has a requirement to write the NDMP backup data from Avamar to tape on a weekly basis. Avamar Tapeout (ATO), installed on the Avamar utility node, will be used for this purpose.

  Which methods can be used to automatically schedule ATO batch jobs?

  A. CRON tab on the utility node or with the Avamar scheduler
  B. CRON tab on the staging server or NetWorker server
  C. CRON tab on the utility node or with an external third-party scheduler
  D. CRON tab on the utility node or with the NetWorker scheduler
  D. CRON tab on the utility node or with the NetWorker scheduler

• Question 4:

  An EMC Avamar customer has a two-node Microsoft SQL 2008 cluster with one instance of Microsoft SQL. To ensure successful backups of the SQL database, what is the order for installation?

  A. Install the Avamar Windows client and Avamar SQL client on both nodes in the cluster. Configure the Avamar Cluster Client on the active node in the cluster.
  B. Install the Avamar Windows client and Avamar SQL client on both nodes in the cluster. Create AvamarBackupUser and configure the Avamar Cluster Client on both nodes in the cluster.
  C. Install Avamar Windows client on both nodes. Install the Avamar SQL client on the active node in the cluster.
  D. Install the Avamar Windows client and Avamar SQL client on both nodes in the cluster. Configure the Avamar Cluster Client on both nodes in the cluster.
  A. Install the Avamar Windows client and Avamar SQL client on both nodes in the cluster. Configure the Avamar Cluster Client on the active node in the cluster.

• Question 5:

  A Dell EMC Avamar backup administrator is experiencing problems with the backup of multiple databases. The databases are running on a Microsoft Exchange 2010 server with a dual core processor. Due to slow backup performance, the backup cannot be completed before the backup window ends. The sizes of the databases are equal and they are running on the same disk.

  What should be done to correct this issue?

  A. Group the backup streams by database
  B. Set the backup streams to 5
  C. Disable multi-streaming in the dataset
  D. Group the backup streams by volume
  A. Group the backup streams by database

• Question 6:

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

• Question 7:

  A Dell EMC Avamar server is performing image backups of a Windows VM on a Hyper-V standalone server. The administrator wants to restore a single file from an image backup back to its original location. The Windows VM cannot have Avamar software installed onto it.

  What must the administrator do to restore the file as soon as possible?

  A. Restore the image using the manual provisioning option, and then use third-party tools to extract the file
  B. Restore the file directly from the Avamar server to the VM
  C. Restore the image to a new virtual machine, and then transfer the file to the VM
  D. Restore the file to a Windows host with the GLP plug-in, and then transfer it to the VM
  A. Restore the image using the manual provisioning option, and then use third-party tools to extract the file

• Question 8:

  Which DB2 backup is a backup of a table space?

  A. AVAMAR.0.db2inst3.NODE0000.CATN000020170403.001
  B. AVAMAR.1.db2inst3.NODE0000.CATN000020170403.001
  C. AVAMAR.3.db2inst3.NODE0000.CATN000020170403.001
  D. AVAMAR.4.db2inst3.NODE0000.CATN000020170403.001
  A. AVAMAR.0.db2inst3.NODE0000.CATN000020170403.001

• Question 9:

  An EMC customer is protecting 300 virtual machines (VMs) with guest level backup. All VMs reside on the same ESX server. The administrators are concerned with the CPU spike during backups since Avamar is trying to initiate as many backups as possible.

  What is the best practice for preventing this spike in CPU on the ESX server host?

  A. Use network throttling parameters in the advanced options of the dataset.
  B. Reduce the connections per node limit on the Avamar server.
  C. Schedule each virtual machine to begin backups one hour apart.
  D. Migrate some of the VMs to another ESX host.
  A. Use network throttling parameters in the advanced options of the dataset.

• Question 10:

  A Business implemented SharePoint 2010 in their environment and uploaded many business documents onto the SharePoint from multiple file servers. They also set up backups of their SharePoint farm with the Avamar SharePoint VSS plug-

  in.

  They discovered that backups of their backend SQL server databases (DBs) were running long so they started using the SQL plug-in to perform incremental backups of their SQL databases.

  What should you advise the customer?

  A. More storage space is needed to back up the databases.
  B. SharePoint content DB will not be backed up with SQL plug-in.
  C. Granular level recovery is supported with the SQL plug-in.
  D. The SQL plug-in can be used for SharePoint Disaster Recovery.
  A. More storage space is needed to back up the databases.
