The EMC account team has been asked to design a NetWorker backup solution with the following requirements.

1.

One copy of backup data needs to be stored locally.

2.

An additional copy of backup data needs to be stored on tape at an offsite location.

What should be done to satisfy the new regulations with minimal impact to the current backup performance?

A. Clone to tape and send the clone copy to the remote location

B. Back up the data concurrently to the remote and local locations

C. Archive the backup data to the remote location

D. Archive the data to the remote location before being backed up locally

An EMC customer has been using NetWorker backup and has recently added an Avamar system for file system backups. The customer wants to move all backups to the Avamar system to take advantage of deduplication. They are currently backing up Sybase and SAP with NetWorker.

What is your recommendation to meet these requirements?

A. Configure Avamar as a deduplication Storage Node in NetWorker to administer all backups

B. Utilize native database tools to back up to flat files, then use Avamar to back up the resulting files

C. Use pre- and post-processing scripts to shut down the databases and perform a cold backup with Avamar

D. Use snapshots to mount the databases to a proxy server for backups

You are designing an EMC NetWorker deduplication solution using EMC Avamar for a customer. When performing a backup containing multiple save sets to a deduplication node, what is the recommended maximum number of save sets that can be backed up concurrently?

A. 2

B. 4

C. 6

D. 8

An existing EMC NetWorker customer has been backing up their VMware environment using VMDKs to a CIFS-attached EMC Data Domain system. Recently, they have added another 80 TB to their primary VM storage. While their deduplication rates have exceeded expectations, they are starting to overrun their backup window. Which solution compliments their existing infrastructure?

A. Introduce a VTL configuration to the Data Domain system and transfer data over Fibre Channel

B. Add additional NetWorker storage nodes into the backup environment

C. Switch the NetWorker VMDK configuration to a NetWorker guest client configuration

D. Use Change Block Tracking on the VMware side and introduce DD Boost into the NetWorker and Data Domain configuration

An EMC NetWorker customer is backing up all clients using EMC Avamar deduplication. They have a

requirement for backup redundancy for disaster recovery.

What is recommended to provide this protection?

A. Replicate backup data in Avamar, clone deduplication metadata in NetWorker

B. Replicate backup data and deduplication metadata in Avamar

C. Replicate deduplication metadata in Avamar, clone backup data in NetWorker

D. Clone backup data and deduplication metadata in NetWorker

An EMC NetWorker customer is considering capacity-based licensing. What can be used to determine the capacity size they would need to license?

A. Asset Management and Planning appliance

B. NetWorker License Conformance Report

C. NetWorker Management Console Status reports

D. Combined capacity of all NetWorker devices

A customer wants to determine how much data can be transmitted in their network. The network environment includes the following:

LAN speed = 4 Gb Bandwidth = 50 Mbps RTT = 50 ms

What is the customer's bandwidth delay product (BDP)?

A. 2000 bytes

B. 76 Kb

C. 305 Kb

D. 5 MB

Scenario

A customer with a fully virtualized environment has four ESX 4.1 servers in a cluster with a SAN solution for storage. Each ESX server is hosting 40 virtual machines and all virtual machines have the same local disk configurations:

Disk1 = 50 GB Disk2 = 100 GB Disk3 = 256 GB

In addition, the environment includes a NAS filer. The average time to fully backup all virtual machines on one ESX server using EMC DD Boost is three hours.

The customer is interested in implementing an EMC NetWorker solution with Data Domain as a backup device. The backup server, storage nodes, and proxies are SAN-attached.

Refer to Scenario .

When using VADP backups with EMC NetWorker, which transport mode is recommended for virtual machines with IDE virtual disks?

A. NBD

B. Hotadd

C. SAN

D. RDM

You are asked to design an EMC NetWorker backup solution for a customer's data center with multiple database applications and a large amount of clients and data. The NetWorker backup server needs to be configured and set up properly for the customer environment.

What is a design consideration for the NetWorker backup server?

A. RAID 10 is recommended for the NetWorker server if the NetWorker server exceeds 100 parallel sessions.

B. RAID 5 is recommended for the NetWorker server if the NetWorker server exceeds 100 parallel sessions.

C. Set NetWorker server Parallelism to the total number of Max Sessions on all devices.

D. Create multiple NetWorker groups with a maximum of 100 clients per group and enforce Group Parallelism.

You are designing a new backup solution for a customer where there are eight remote sites and one central site. At the present time, all sites have separate backup environments.

The customer wants all backups to be consolidated using one backup product. They require that all backups be replicated many-to-one back to the central site with minimal impact on the WAN. They also want their desktop/laptop clients to perform their own backups and restores. Monitoring of all sites is required using Data Protection Advisor.

Which EMC solution will meet the requirements?

A. Avamar

B. Networker

C. Replication Manager

D. Data Domain
