C. Set the client parallelism value to 8

D. Add the Avamar server name to each client's server file

A potential EMC customer has a T1 circuit betweentheir production data centreand their disasterrecoverydata centre that are 2,000 miles apart.Theycurrentlybackup their Linux systems to physical tape usingHP Data Protector Theybackupan average of 20 TB each night.

The customer wants a backup solutionthat improves backup andrestore reliabilitytreduces overall costs.and eliminatesphysical tape.

What is recommended solution?

A. Data Domain with replication over IP

B. EMC Disk Library with Remote Copy over IP

C. EMC Disk Library with Consolidated MediaManagement over FC

D. Data Domain with OST and replication over IP

A customer wants to back up VMware using Avamar to leverage deduplication. They have been and want to continue performing VCB backups.

Where will the Avamar client and the Avamar VCB Interoperability Module be installed?

A. Backup proxy server

B. ESX server and backup proxy server

C. Virtual machines guest operating system

D. Virtual machines and backup proxy server

The EMC account team has been asked to design a NetWorker backup solution. The customer's environment consists of a Microsoft Exchange Server 2007 Cluster Continuous Replication (CCR) deployment on a CLARiiON disk array with EMC VSS Provider and an EMC Disk Library.

The customer wants to leverage the Microsoft VSS framework to back up their Exchange server from the Exchange Server 2007 CCR passive node. What needs to be considered when designing this backup solution?

A. Backup from the Exchange Server 2007 CCR passive node will fail after Exchange Server 2007 CCR role change

B. NetWorker Module for Exchange needs to be installed on both the Exchange Server 2007 CCR active node and passive node

C. Exchange Server 2007 database and transaction logs must reside on the same volume

D. Exchange Server 2007 system path and transaction logs must reside on separate directories

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

An existing EMC NetWorker customer is planning to integrate EMC Data Domain systems into their backup infrastructure. They would like to:

Backup their Microsoft Windows client data using CIFS to a Data Domain system Take weekly Data Domain system snapshots of Windows client backup data Backup their Linux client data using NFS to a Data Domain system Take daily Data Domain system snapshots of Linux client backup data Based on EMC best practice, what should be considered when designing the Data Domain file system layout?

A. Create a separate MTree for CIFS and NFS client data

B. Create an MTree named "data" and create separate sub-directories for CIFS and NFS client data

C. Under /backup MTree, create separate sub-directories for CIFS and NFS client data

D. Create separate storage units for CIFS and NFS client data

A customer wants an EMC Avamar solution that provides 8 TB of deduplicated data protection. In addition, they need to protect a VNX system and export data to tape. They anticipate data growth of another 6 TB in the next year.

Which Avamar components should be used to architect the solution, in as few nodes as possible, while meeting sizing best practices?

A. Avamar multi-node server, and an NDMP Accelerator and Media Access nodes

B. NetWorker deduplication server and tape export, and an NDMP Accelerator node

C. vamar integrated with Data Domain and a Data Domain VTL license

D. Avamar Business Edition server, and an NDMP Accelerator and Media Access nodes

A customer has data at several remote offices that needs to be backed up over a secure WAN connection to their data center. However, bandwidth is constrained. A major portion of their backup data will be file system data. In addition, they have a 6 TB database in the primary data center with a 6% change rate that needs to be backed up.

Which EMC backup solution is recommended for this customer?

A. NetWorker with Avamar integration

B. NetWorker with Data Domain and CIFS

C. NetWorker with Data Domain and DD Boost

D. Avamar server with Avamar Virtual Edition

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 sized and configured properly for the customer environment.

What is a design consideration for the NetWorker backup server?

A. Assign large clients to a separate NetWorker group and start the group first.

B. Assign large clients to a separate NetWorker group and start the group last.

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

D. Create multiple NetWorker groups with up to 100 clients per group and disable Group Parallelism.
