have image-level backup while having a low impact on the ESX server. In addition, they want the ability to

perform file-level restores of their Microsoft Windows clients.

Which backup method will meet the customer's needs?

A. VMware Consolidated Backup

B. Avamar agent on each guest OS

C. AcCelerrator Node

A customer has been using lz Local Compression when backing up their data to an EMC Data Domain system. An audit of their storage content shows that they can effectively use gz compression for their data. What should be considered before changing the Local Compression type?

A. Overall system performance will improve with the new compression

B. Existing data will not be recompressed; only new data will be gz compressed

C. New compression on the old data will not take effect until the next system cleaning

D. Changes must be made at the beginning of a 20-hour backup window

Refer to Scenario .

The Chief Technical Officer (CTO) of a large company has directed their IT management staff to examine corporate wide operations and find ways to limit the cost of operations. The corporate directives have prompted adoption of company policies that include the use of virtualization for all new servers and as many services as possible. The company is subject to government regulations concerning data retention policies for confidential data. Data has to be retained for seven years.

An audit of the backup and recovery environment is performed. The exhibit shows a typical site and how it is connected to the disaster recovery environment. Data in the primary site is configured on VMAX storage using FAST-VP to support multiple work load types on a single storage array.

Data is protected by SRDF/A to a remote VMAX which acts as a target for multiple sites. The remote copy of the data is snapped and copied to tape. Retention is accomplished to governmental standards by offsite storage of tape in a remote protected facility.

The company has noted that it has the following requirements in any proposed architecture for the backup and recovery environment:

1.

Reduced power consumption

2.

Reduced floor space consumption

3.

Reduced storage capacity consumption

4.

Lower WAN bandwidth utilization

5.

Shorten RPO

6.

Decrease RTO

7.

Increase security

8.

Lower Total Cost of Ownership (TCO)

The company has been unable to achieve the RTO required by their Service Level Agreement to their major clients. If they want to limit TCO, which EMC solution should be proposed?

A. Avamar

B. NetWorker and Avamar

C. NetWorker and Data Domain

D. Data Domain

A customer has been using EMC Avamar to leverage deduplication for VMware. They have been performing guest-level backups and now want to also perform VMware image backups for disaster recovery.

In order to use image backups, what is recommended in the environment?

A. SAN-attached Data Store

B. Image proxy Windows host

C. Avamar client agent running on the vCenter server

D. Avamar client running on each guest

An EMC Avamar customer is receiving capacity warning messages from their system. They recently deleted several clients including their backup data. The deleted client data is 2 TB in size. After garbage collection completed, the customer saw less space collected than they had anticipated. What would cause this behavior?

A. Chunks are used for other backups

B. HFS check still needs to run

C. Partials have been removed

D. HFS check failed

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.

Each remote storage nodes' device will have a target session of 12 and a max target session of

60. By default, what is the maximum nsrmmd count per device?

A. 5

B. 9

C. 12

D. 60

You have been asked to perform an assessment of a customer's backup environment. You want to measure the current network bandwidth before determining any changes to the backup design.

Which tool should you use?

A. iperf

B. netscan

C. ipstat

D. netstat

You are designing an EMC Data Protection Advisor (DPA) solution for a large NetWorker customer using both DPA clustering and replication.

What is a consideration when determining the server layout for application and datastore servers?

A. Implement DPA clustering in a virtualized environment

B. Use clusters containing both application and datastore servers

C. Connect a DPA datastore to each cluster VLAN in the solution

D. Configure DPA replication between master and secondary application servers
