EMC E20-329 Online Questions & Answers

• Question 61:

  An EMC NetWorker customer has an Oracle database client. To achieve acceptable backup performance, they have configured the backup to use four RMAN channels.

  A. Data from each RMAN channel must be sent to a separate deduplication node
  B. Less than six RMAN channels in a deduplicated backup will perform poorly
  C. More than two RMAN channels in a deduplicated backup will cause the backup to fail
  D. Separate cache files are recommended for each RMAN channel
  D. Separate cache files are recommended for each RMAN channel

• Question 62:

  A customer wants to implement a Data Protection Advisor solution in their Microsoft Windows backup environment. After the proof of concept installation, you discover that performance of the iAnywhere database is degraded. What is the most likely reason?

  A. More than 250 clients
  B. O/S environment is unsupported
  C. Exceeds the number of databases
  D. TCP ports are disabled
  A. More than 250 clients

• Question 63:

  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 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 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 has been unable to achieve the RTO required by their Service Level Agreement to their major clients. If they want to limit TCO, which EMC solution should be proposed?

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

• Question 64:

  An EMC NetWorker customer is considering implementing NetWorker AES encryption to secure backups on one of their application servers. What is a concern when using AES?

  A. Increased CPU utilization on the backup client
  B. Tape must be used as a destination device
  C. Backup data cannot be multiplexed
  D. Increased CPU utilization on the backup server
  A. Increased CPU utilization on the backup client

• Question 65:

  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

  The backup window for all branch offices is 15 hours on Friday evenings. What is the throughput required between Seattle and Chicago to enable these replications?

  A. 1.33 GB/hour
  B. 2.67 GB/hour
  C. 26.7 GB/hour
  D. 13.33 GB/hour
  A. 1.33 GB/hour

• Question 66:

  An EMC NetWorker customer is considering using the deduplication feature with Avamar. What is a requirement when performing backups to a deduplication node?

  A. Deduplication backup metadata must be stored on tape
  B. NetWorker client host can only perform deduplication backups
  C. Deduplication node must be RAIN protected
  D. First backup to a deduplication node must be a Full backup
  D. First backup to a deduplication node must be a Full backup

• Question 67:

  A customer wants to know why their backup performance to an EMC Avamar multi-node server has decreased. Initially they were seeing an ingest rate of approximately 5 to 7 GB/hr/node. Recently they estimated that the ingest rate has slowed to around 3 to 5 GB/hr/node.

  What is a probable cause for the decrease in the average ingest rate?

  A. Stripes contain more data, and steady state has been achieved.
  B. HFS check has found errors and has not been completing successfully.
  C. A large number of backups have expired, causing new stripes to be created.
  D. Garbage collection is not running, causing new stripes to be created.
  A. Stripes contain more data, and steady state has been achieved.

• Question 68:

  A customer has a Data Domain appliance that has reached 90% of maximum capacity. The customer does not want to purchase any additional storage. What will increase the average available capacity of the Data Domain appliance?

  A. Decrease the backup retention period
  B. Increase the snapshot expiration period
  C. Increase the number of streams
  D. Decrease the cleaning frequency
  A. Decrease the backup retention period

• Question 69:

  A customer has Oracle 9i running on a Microsoft Windows server. They want to deploy hot backups because the database cannot be shut down. What is a design consideration for backups when using the Avamar plug-in for Oracle?

  A. Use of exclude/include lists in a dataset is supported
  B. Backups initiated through Avamar Administrator are always Full backups
  C. File system backup should include the entire root directory for each Oracle instance
