• Question 261:

  A customer wants to change their backup and recovery strategy for their VMware Windows environment. They do not need to use encryption for the backup of the virtual machines. The customer plans to implement Avamar full image backups. Over 80% of restore requests are for single files. As a result of the restore, which item is unavailable?

  A. ACL
  B. VMDK
  C. Proxy
  D. File
  A. ACL

• Question 262:

  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 the 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 must 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 indicated that it has the following requirements in any proposed architecture for the backup and recovery environment:

  Reduced power consumption

  Reduced floor space consumption

  Reduced storage capacity consumption

  Lower WAN bandwidth utilization

  Shorten RPO

  Decrease RTO

  Increase security

  Lower total cost of ownership (TCO)

  

  Refer to Scenario and the exhibit.

  To satisfy the stated requirements, the customer wants to use a virtual appliance to limit power and space consumption in their smaller locations. To replace the current SRDF/A replication model, which EMC technology should be recommended?

  A. Avamar Virtual Edition
  B. Data Domain
  C. NetWorker NDMP
  D. File Management Appliance VE
  A. Avamar Virtual Edition

• Question 263:

  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
  A. NBD

• Question 264:

  A backup administrator has been performing image level backups of their Hyper-V virtual machines to their Avamar server. They need to recover a single file to one of their Linux virtual machines. What must they do to recover this file?

  A. Restore the file to a Windows machine, then transfer it to the Linux VM
  B. Install the GLR plug-in onto the Linux VM and restore directly to it
  C. Use VADP to restore the file directly to the Linux VM
  D. Use Desktop/Laptop on the Linux VM and restore the file directly to it
  A. Restore the file to a Windows machine, then transfer it to the Linux VM

• Question 265:

  A customer has a new EMC Avamar server with four 3.9 TB data nodes. This server is backing up two Avamar clients. The first client has 10 GB of RAM and two file systems. The first file system has 2 million files consuming .75 TB. The second file system contains 3 million files consuming 1 TB of space. The second client has 8 GB of RAM and one file system containing 4 million files is consuming 1.2 TB of space. Both clients will belong to the same backup group. How long will the steady state backup group be expected to run?

  A. 4 hours
  B. 5 hours
  C. 6 hours
  D. 9 hours
  D. 9 hours

• Question 266:

  An existing EMC NetWorker customer is evaluating options for upgrades within their backup solution. The customer is interested in replacing their current tape- based infrastructure with a backup-to-disk product. The customer currently uses EMC VNX arrays for their SAN storage.

  The solution needs the ability to retain certain backups for long periods of time due to compliance reasons as well as minimize the amount of power and rack space required. In addition, all backups must go offsite on a daily basis.

  Finally, the customer wants the ability to use a new 10 GigE infrastructure they are planning to deploy within their data center. They want to minimize the amount of disruption to their current daily procedures in order to avoid re-training existing staff. Which storage solution can be integrated with NetWorker to satisfy these requirements?

  A. LUNs from the VNX
  B. DD Archiver appliance with VTL
  C. Avamar server
  D. DD Archiver appliance with DD Boost
  B. DD Archiver appliance with VTL

• Question 267:

  An existing EMC Data Domain customer is evaluating new backup software and hardware for their environment. Their current environment consists of a single data center along with several remote sites.

  The customer is interested in consolidating all backup hardware into their primary data center while still being able to do remote backups. In addition, they want the ability to perform backups directly to tape for certain applications in order to

  send the tapes offsite for long-term retention.

  The customer plans to keep their current Data Domain system as part of any new configuration. However, they want to look at options to optimize performance without adding additional infrastructure.

  The final requirement is that the entire solution be managed from a single unified interface in order to configure and track backup jobs. Which EMC solutions can address these requirements?

  A. NetWorker with DD Boost and an integrated Avamar system
  B. NetWorker with DD Boost along with remote storage nodes
  C. Avamar with an integrated Data Domain system
  D. NetWorker with DD VTL and an integrated Avamar system
  A. NetWorker with DD Boost and an integrated Avamar system

• Question 268:

  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.
