E20-895 Online Practice Questions and Answers

An EMC employee has been assigned to run securedelete against two clients for a total of 20 GBs on an Avamar server. During a planning discussion with the customer, they want to know what the impact on their Avamar server would be

while securedelete is running.

What is the correct response to the customer?

A. GSAN will be in admin mode and the Avamar server will be read only

B. Avamar will continue to function with a limited amount of available threads

C. GSAN will be shut down during the extent of the securedelete task

D. Avamar will continue to function without any limitations

An EMC customer has accidently backed up an EMC VNX through NDMP that contained highly classified data to an Avamar server. The data must be removed from the Avamar server in a method that is compliant with U.S. Department of Defense standards.

What is the correct method to securely delete the backups from the Avamar server with minimal interference to existing backups from other clients?

A. Issue securedelete to remove the client data from the Avamar server and existing checkpoints

B. Issue securedelete against the entire Avamar server

C. Issue securedelete to remove the client data from the Avamar server and MC_BACKUPS

D. Issue securedelete to remove the client data from the Avamar server

An EMC customer has a Celerra that has been running NDMP backups successfully for a few months. The customer is planning to migrate a substantial amount of data to the NAS. They want to add another Accelerator Node and move some

of the volumes to the new Accelerator.

Which step should be taken to avoid having to run a Level 0 backup again?

A. Create a GSAN account with the new name before the backup takes place

B. Move all the var/account directories to the new Accelerator

C. Ensure the same account name is used on the new Accelerator

D. Ensure the force incremental button is checked before the first job runs

An EMC Avamar customer has noticed that their NetWorker deduplication node is 90% full. They want to delete all backups older than 60 days. What is the correct process flow for deleting deduplication backups in NetWorker?

A. 1. Backup is marked for deletion by the NetWorker server on the deduplication node.

2. Backup is purged from metadata on the storage node.

3. NetWorker server performs cleanup on the deduplication node.

B. 1. Backup is purged from metadata on the storage node.

2. Backup is marked for deletion by the NetWorker server on the deduplication node.

3. NetWorker server performs cleanup on the deduplication node.

C. 1. Backup is marked as recyclable in NetWorker.

2. Manually run nsrmm

An EMC Avamar customer notices that the Activity Monitor reports "Waiting client" for a particular client in a group backup.

What is a possible cause for this issue?

A. The cid.bin file is missing on the client.

B. ascd is not running on the client.

C. Multiple avtar processes are running on the client.

D. The dispatcher table file is missing on the Avamar server.

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 DB2 is SPARC. Hash calculations take longer than an X86; increase CPU power.

B.

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.

C.

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.

D.

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

An EMC Avamar administrator uses the avtar paramater hashcachemax = 96 to change the maximum size of the hash cache. What is the maximum size in MB that the hash cache will be allowed to grow to?

A. 24

B. 48

C. 96

D. 192

A current EMC NetWorker customer is backing up a mix of Microsoft Windows and Linux servers in their environment. They decided to integrate two Avamar servers into their environment as deduplication nodes. Clients will be configured to back up to the first node with Avamar replication configured between the two.

In the event that the primary deduplication node has failed and is unreachable, what will happen if a restore is initiated?

A. Recovery will be automatically performed from the replication target.

B. Recovery will fail, reporting the deduplication node as unreachable.

C. Recovery will wait until the deduplication node comes online.

D. Recovery will fail, reporting that the client must first be activated on the replication node.

A backup administrator with an existing Avamar 7.0 single-node server wants to integrate a Data Domain appliance running DDOS 5.2 into their backup environment.

To provide disaster recovery of the Avamar server the administrator wants to store Avamar checkpoint backups on the new Data Domain system. When configuring the checkpoint backup, an error is displayed.

What is the possible cause?

A. The Data Domain DDOS version needs to be 5.3 or above.

B. Avamar single-node servers do not support checkpoint backups to Data Domain.

C. Avamar 7.0 does not support checkpoint backups to Data Domain.

D. Data Domain does not support the storing of Avamar checkpoint backups.

A customer's SharePoint environment consists of:

-3 Web front end (WFE) servers

-2 Application servers

-1 Configuration database server

-2 Content database servers

The customer installed it according to EMC best practices for a Federated SharePoint environment by installing an Avamar Sharepoint plug-in on one of the three WFE servers as well as all of the other servers. The WFE with the client

installed fails just prior to the beginning of the backup.

What is the fastest way to get the backup process restarted?

A. Recover the failed WFE prior to backup.

B. Install the front end software on another WFE.

C. Start the backup from one of the application servers.

D. Install the client on all the WFE servers to allow for failover.
