Their SQL database full backups cannot be completed within the backup window. After checking their backup environment, you find that there are adequate resources to meet their backup window.

  What could you do with NetWorker or SQL to increase performance without adding cost and complexity?

  A. Use stripes with SQL database backups
  B. Enable SQL filegroup backups
  C. Increase the value of FILESPERSET
  D. Increase the value of MAXOPENFILES
  A. Use stripes with SQL database backups

• Question 273:

  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
  A. RecoverPoint

• Question 274:

  A customer has had a failure of the primary deduplication node and needs EMC NetWorker to recover the data from the replication node. What will enable recovery from the replication target node?

  A. Replication node is specified in the replication node field of the client resource
  B. NetWorker deduplication node is configured as a dedicated replication target
  C. Replication between deduplication nodes is controlled by the NetWorker server
  D. Replication process and restore of replicated data require native Avamar for recovery
  A. Replication node is specified in the replication node field of the client resource

• Question 275:

  Scnario

  A customer is currently using third-party backup software for Oracle backups and writing backups to third-party physical tape libraries and a VTL. Backups sent to the VTL are then vaulted to tape and transported daily from the primary data center to the third-party facility.

  They are experiencing high backup job failures with backup success rates of approximately 65%. In addition, their time to disaster recovery readiness for backups is greater than 24 hours. The retention period for database backups from disk-based backup is 4 weeks.

  The customer is looking for a solution that will meet the following requirements: Oracle DBA to manage backups through Oracle RMAN Backup their file system data using EMC backup software Perform monthly full backups directly to physical tapes for offsite storage Reduce the backup window to the possible maximum Increase the time to disaster recovery readiness. Increase the retention period for database backups from disk-based backup to 6 weeks No additional WAN bandwidth requirements Low TCO solution Free up the Fiber Channel switch infrastructure Increase operational efficiency

  Refer to Scenario .

  Which EMC solution will meet the customer's requirements?

  A. Data Domain and NetWorker
  B. Avamar and Data Domain
  C. Avamar
  D. Data Domain
  A. Data Domain and NetWorker

• Question 276:

  An existing EMC customer notices that garbage collection is not running in Avamar because the capacity limit has reached. At which capacity limit does garbage collection stop running?

  A. 85%
  B. 90%
  C. 95%
  D. 100%
  A. 85%

• Question 277:

  A customer wants to know why their backup performance to the Avamar multinode f\grid has decreased. Initially they were seeing an ingestion rate of around 5 to 7 GB/hr/node. Recently they estimated that it has slowed to around 3 to 5 GB/ hr/node. What is a probable cause for the decrease in the average ingestion rate?

  A. HFS check has not been completing successfully
  B. A large number of backups have been expired, causing new stripes to be created
  C. New stripes are no longer being created and steady-state has been achieved
  D. Garbage collection is not running, causing stripes to fill and new stripes to be created
  C. New stripes are no longer being created and steady-state has been achieved

• Question 278:

  After a backup assessment, you determined that customer data deduplicates well. After deduplication, the data consists of 100 laptops and desktops with .5 TB, a file server with 5 million files in 1 TB, and several database servers with 5 TB.

  The customer requires deduplication with the shortest possible backup window.

  Which solution should be architected with as few components as possible?

  A. Avamar 7.8 TB single-node integrated with a Data Domain system
  B. NetWorker with a deduplication node
