A data center consisting of six Microsoft Windows file servers must be backed up. Each file server contains 750,000 files and approximately 150 GB of data. The file servers have been tested simultaneously. Each file server can read data from the network and write it to disk at the rate of 75 GB per hour. The data center has a 10 Gigabit Ethernet backbone.

What is the minimum number of Avamar 2 TB data nodes that should be ordered to perform a recovery of all six file servers and achieve a recovery time objective of 8 hours?

A. 1

B. 3

C. 5

D. 7

A customer is considering an EMC Avamar backup solution. They want to know whether Avamar can provide the security benefit of data encryption between the clients and the Avamar server.

What are the "in-flight encryption" considerations?

A. Can be changed at any time and has no performance penalty

B. Can only be set at installation time and has no performance penalty

C. Can be changed at any time and has a significant performance penalty

D. Can only be set at installation and has a significant performance penalty

An EMC Avamar customer is in the testing phase of their new solution. They have backed up several

clients and are now doing some restore tests. They have found that the restore time is not consistent. The

restore time decreases if more than one attempt at the same restore is performed.

Why is the customer seeing these results?

A. Backup jobs are running

B. Restore data is in memory

C. Garbage collection is running

D. Restore data is on faster disks

A customer has decided on EMC Avamar as a solution. They are trying to decide on the amount of nodes to purchase. They want maximum storage capacity.

What is a recommended maximum number of data nodes for an initial Avamar server configuration?

A. 7

B. 8

C. 14

D. 16

An EMC NetWorker backup environment has 300 clients distributed among three subnets. All clients send their backup to the NetWorker server. The customer is experiencing poor performance during backups.

Which modification to the existing environment will improve the backup performance at minimal cost?

A. Convert an existing client with the most data to back up to a storage node in each subnet

B. Install a new host to act as a storage node in each subnet

C. Convert an existing client with the least data to back up to a storage node in each subnet

D. Convert all large clients into dedicated storage nodes

An EMC Avamar customer is running a backup that is being directed to a Data Domain system. Although the backup completed successfully, the customer decides to delete the backup.

When does data, from expired backups, move from /cur to /DELETED?

A. Next time the Avamar system runs garbage collection

B. Immediately after expiration on the Avamar system

C. Manually deleted on the Data Domain system by the administrator

D. Next time the Data Domain file system cleaning operation runs

Scenario

A customer is looking to perform a data center refresh. They want to standardize their backup infrastructure by using EMC NetWorker, Avamar, and Data Domain in an integrated environment. The environment consists of:

A primary data center - NetWorker server, Data Domain, and Avamar A disaster recovery (DR) data center

-Data Domain only 220 remote sites Each remote site consists of approximately 30 clients and 1 storage node LAN speed at and between all sites is 1 Gb

The company's Chief Technology Officer (CTO) has indicated that data must be backed up locally. Then, the data must be copied offsite to the primary data center and DR data center. The entire solution must be managed from a single unified interface in order to configure and track backup jobs.

The company is subject to government regulations concerning data retention policies for confidential data. Data has to be retained for seven years on tape at the DR data center.

Assume each remote site has 30 clients, three devices per remote storage node, and NetWorker Power Edition are used. At a minimum, how many datazones will be needed?

A. 1

B. 2

C. 3

D. 4

A customer's Data Domain DD2500 system has 32 active MTrees. They notice performance issues when using the configuration.

What is the minimum number of MTrees that should be removed from active use to improve performance?

A. 14

B. 16

C. 18

D. 20

A customer wants to perform an EMC NetWorker Assessment on one data zone. What is required?

A. Mitrend Quick Scripts

B. Workbench Gap Analysis

C. Workbench FSA Scan

D. NetWorker Management Console
