EMC EMC Certifications E20-329 Questions & Answers

• Question 181:

  An EMC NetWorker customer has been using an EMC Disk Library (EDL) for over four years. The EDL

  has reached its capacity limits. The customer is in the process of virtualizing as many physical servers as

  possible to reclaim data center floor space. They are backing up numerous 8 TB databases.

  The customer is interested in replacing the EDL and is concerned about the amount of backup traffic over

  the network. The replacement must maintain a single point of backup administration and reduce backup

  times for their growing virtualized environment.

  What is the recommended solution?

  A. Replace the EDL with Data Domain using DD Boost

  B. Add a deduplication storage node to NetWorker for VMware backups and replace the EDL with Data Domain for large databases

  C. Add an Avamar server for VMware backups and use NetWorker with DD Boost to back up the physical servers and large databases to a Data Domain

  D. Add a deduplication storage node to NetWorker for database backups and replace the EDL with Data Domain for VMware and physical servers

  Correct Answer: D

• Question 182:

  A customer is piloting an EMC Data Domain system.

  

  Based on the Data Domain statistics shown in the exhibit, which type of data is being backed up?

  A. New data

  B. DD Boost backups

  C. Redundant data

  D. Replicated data

  Correct Answer: A

• Question 183:

  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

  Correct Answer: A

• Question 184:

  A company has a business model where they purchase small companies and let them run independently. Storage, backup and recovery, and server technology implementations vary between the companies.

  The company has determined that they must initiate a backup and recovery strategy that will allow for recovery of any of the small companies in case of a complete site failure. In addition, they want to start to use a single standard model in an effort to move forward towards standardization across the entire enterprise.

  A backup and recovery audit has found that the companies all use a basic method of backup and recovery consisting of enterprise backup software backing up to a tape library for all critical corporate data. The company wants to replicate backup sets from each site to their corporate location.

  Which EMC solution should be used to minimize impact on the environment while minimizing cost?

  A. Install Avamar as the backup technology at each site and replicate to a central Avamar for recovery

  B. Install Data Domain as a VTL for each site and replicate to a central Data Domain for recovery

  C. Install Data Domain as a VTL with NetWorker for each site and replicate to a central Data Domain for recovery

  D. Install NetWorker at each site and configure NetWorker Archiver to a central Data Domain for recovery

  Correct Answer: C

• Question 185:

  A new customer is using EMC NetWorker to manage backup and recovery within their environment. They

  would like to have all backup data go to Advanced File Type devices and be spread across the four

  devices that they are currently using.

  The customer wants to use an additional device for new streams once there are eight running on a single

  device Backups should not queue if another device is unavailable.

  Which parameter should be set?

  A. Pool Parallelism

  B. Savegroup Parallelism

  C. Max Sessions

  D. Target Sessions

  Correct Answer: A

• Question 186:

  You are meeting with a customer regarding an EMC Avamar and Data Domain integrated solution. The customer states that they would like their backup window to be 24 hours.

  What is a consideration?

  A. Maintenance windows

  B. Multiplexing of backups

  C. Number of storage nodes

  D. Proprietary network infrastructure

  Correct Answer: A

• Question 187:

  An EMC NetWorker customer has an Oracle database client. To achieve acceptable backup performance, they have configured the backup to use multiple RMAN channels. The customer wants to add EMC Avamar deduplication for this backup. What is a consideration before proposing this design change?

  A. Data from each RMAN channel must be sent to a separate deduplication node

  B. More than 2 RMAN channels in a deduplicated backup will cause the backup to fail

  C. Less than 4 RMAN channels in a deduplicated backup will perform poorly

  D. Multiple cache files are created on the client when using multiple channels

  Correct Answer: D

• Question 188:

  At a customer meeting, you discover that the backup administrator is new to the position. What can be used to determine the health of their backup environment?

  A. Asset Management and Planning Appliance

  B. Data Deduplication Assessment

  C. EMC Backup Assessment

  D. File System Assessment

  Correct Answer: C

• Question 189:

  An existing customer has an EMC Data Domain system that is the same model as that used in the Data Domain Archiver. The customer has decided to retain a portion of their backups for five years. They would like to upgrade their Data Domain system to an Archiver. Because the customer manages their existing Data Domain system, they would like to perform the installation themselves. How would you advise the customer?

  A. An upgrade to a Data Domain Archiver is not supported in the field

  B. A license must be purchased to expand the active tier above 146 TB

  C. Customer can convert a regular file system to an archive system

  D. An archive limitation of three years for all archive unit exists

  Correct Answer: B

• Question 190:

  A company purchased an EMC Avamar and Data Domain integrated solution six months ago. Their environment contains file system, Microsoft Exchange, and Microsoft SharePoint data. They are now ready to purchase a replication solution to support their disaster recovery strategy.

  Which design supports their environment?

  A. Avamar primary server and Data Domain primary system replicating to a secondary Data Domain.

  B. Avamar primary server replicating internal data to the primary Data Domain system. Data Domain replicating to a secondary Data Domain.

  C. Avamar primary server replicating to an Avamar secondary server. Data Domain primary system replicating to a secondary Data Domain.

  D. Data Domain system replicating both Avamar and Data Domain to secondary systems.

  Correct Answer: C
