• Question 161:

  Refer to Scenario .

  A customer is looking to modernize their backup infrastructure. The current environment consists of a

  single centralized data center and several remote sites. The centralized data center hosts all core services

  and applications. The remote office primarily consists of sales personnel with 4000 use-North America,

  500 in Europe, and 300 in Asia using file servers.

  The current backup environment at the primary site uses CommVault backing up to a Fibre Channel tape

  library that contains four ITO-4 tape drives. Currently they are backing up a number of file servers as well

  as several databases that have average change rates of 7% daily Remote office backups are currently

  performed by having users copy files to regional file servers that are then backed up to tape.

  In the past few months, the customer has experienced problems with getting backups to finish within their

  defined windows as well as issues with the tape library hardware. They now have concerns about gaps in

  their backup coverage as well as the reliability of the tape media. In addition, an internal audit shows a

  large amount of user-generated data is unprotected on remote user laptops.

  The customer is looking for a common platform to standardize their backups. They want a solution which

  allows for a centralized infrastructure so -they do not need to rely on remote resources to address

  hardware and software issues. The other goal is to move away from tape to a more reliable disk-based

  solution.

  The customer is impressed by the performance of Avamar file system backups. However, they have

  concerns about its ability to handle the backups of their databases. Which solution should be

  recommended?

  A. Continue to backup the databases to tape

  B. Configure a standalone Data Domain appliance

  C. Integrate a Data Domain appliance with Avamar

  D. Add more storage nodes to the Avamar system

  Correct Answer: C

• Question 162:

  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 virilization 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 wants to replace their SRDF/A technology with an EMC solution that can satisfy all of the requirements stated by the CTO. Which technology should be used to replace replication SRDF?

  A. RecoverPoint

  B. NetWorker

  C. Avamar

  D. Data Domain

  Correct Answer: A

• Question 165:

  Refer to Scenario.

  An enterprise customer would like to better address business continuity at all branch offices. Their

  corporate data center resides in Chicago, Illinois and they would like all branch office data centers to use

  Chicago as the destination for replicating backups.

  Each branch office has a mixture of databases, e-mail, and other data that need full backups on Friday

  evenings and daily incremental backups. Based on their new Chief Technology Officer's experience with

  deduplication, they are installing EMC Data Domain devices at all sites to take advantage of the lower

  bandwidth requirements for backup replications.

  The backup requirements for the branch offices are:

  1.

  New York, Denver, and Houston = 100 GB full, 20% daily incremental

  2.

  SCO, Seattle, and Kansas City = 20 GB full, 20% dairy incremental

  A. Collection

  B. Pool

  C. Directory

  D. MTree
