EMC EMC Certifications E20-329 Questions & Answers

• Question 171:

  A. Application backup data is crash-consistent

  B. File-level restore granularity available for all systems

  C. Low load on the ESX server during backups

  D. No proxy server required for the backup environment

  Correct Answer: A

• Question 172:

  A large EMC NetWorker customer is gathering installation requirements for a new NetWorker installation. Based on best practices, where should the NetWorker indexes be located to provide the most flexibility?

  A. Separate internal disk from the O/S

  B. Protected NAS share

  C. SAN volume

  D. Large SCSI-attached disk

  Correct Answer: C

• Question 173:

  An EMC NetWorker customer is backing up all clients using EMC Avamar deduplication. They have a

  requirement for backup redundancy for disaster recovery.

  What is recommended to provide this protection?

  A. Replicate backup data in Avamar, clone deduplication metadata in NetWorker

  B. Replicate backup data and deduplication metadata in Avamar

  C. Replicate deduplication metadata in Avamar, clone backup data in NetWorker

  D. Clone backup data and deduplication metadata in NetWorker

  Correct Answer: A

• Question 174:

  A customer wants to improve the performance of their EMC Data Domain system. After checking their weekly reports, they notice that on the same day each week, file system performance is impacted. At first the customer thought the performance issue was caused by full backups that run on Friday. However, the performance issue is occurring on Tuesday.

  What is a possible reason for this behavior?

  A. Cleaning throttle is set to 90

  B. Directory replication is running

  C. File system is in a disabled state

  D. Full database backups are running

  Correct Answer: B

• Question 175:

  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

  Correct Answer: B

• Question 176:

  A new EMC Avamar customer wants advice on setting up their groups and schedules. They are migrating

  from a traditional tape backup solution with a mixed retention policy. Both Microsoft Windows and Solaris

  clients will be backed up.

  What follows EMC best practices for setting up groups and policies?

  A. Minimize the number of groups by including the different operating systems in the same dataset and using advanced retention

  B. Create a unique group for each dataset. schedule, and retention policy

  C. Enable the default group and use that group for all backups as every client is added to this group upon activation

  D. Use a separate group and dataset for each operating system type and create unique retention policies for Monthly, Daily, Weekly, and Yearly backups

  Correct Answer: D

• Question 177:

  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

  Correct Answer: B

• Question 178:

  During final design conversations with an EMC Avamar customer, they indicate that they have certain data

  that needs to be carefully secured during transit. This data is typically transferred at different times and in

  different groups.

  Which type of encryption would address the customer's concern?

  A. Blowfish encryption enabled at the group policy level

  B. AES-256 encryption automatically enabled for all backups

  C. AES-256 encryption set at the time of the backup operation

  D. AES-128 encryption set at the time of server installation

  Correct Answer: C

• Question 179:

  Refer to the Exhibit.

  

  A customer is planning to have a disaster recovery solution for their backup environment. As part of Phase 1, they want a replica for their EMC Data Domain system. Due to some budget restrictions, they need to have a low investment solution. What is the recommended minimum configuration needed for the replica?

  A. Replication on both Data Domain systems

  B. Replication and VTL on both Data Domain systems

  C. Optimized duplication on both Data Domain systems

  D. DD Boost and replication on both Data Domain systems

  Correct Answer: C

• Question 180:

  An existing EMC NetWorker customer has been backing up their VMware environment using VMDKs to a CIFS-attached EMC Data Domain system. Recently, they have added another 80 TB to their primary VM storage. While their deduplication rates have exceeded expectations, they are starting to overrun their backup window. Which solution compliments their existing infrastructure?

  A. Introduce a VTL configuration to the Data Domain system and transfer data over Fibre Channel

  B. Add additional NetWorker storage nodes into the backup environment

  C. Switch the NetWorker VMDK configuration to a NetWorker guest client configuration

  D. Use Change Block Tracking on the VMware side and introduce DD Boost into the NetWorker and Data Domain configuration

  Correct Answer: B
