EMC EMC Certifications E20-329 Questions & Answers

• Question 201:

  A customer's environment consists of the following:

  1.

  Linux servers with an Oracle database

  2.

  Microsoft Windows with SQL

  3.

  Full weekly backups for Oracle with a one-month retention period Dairy incremental with a two-week retention

  4.

  Full weekly backups for SQL with two retention periods

  You collect the information in order to determine the capacity needed for an EMC Data Domain solution. Which calculation will show the best trade-off between retention and compression?

  A. Calculations with the compression rate for the database

  B. Calculations with longer retention times

  C. Calculations across a range of retention times

  D. Calculations with minimal compression rates

  Correct Answer: A

• Question 202:

  An EMC NetWorker customer is experiencing poor backup performance. Your analysis determines that significant host resources are used to manage low-level network handshaking operations during backup. Based on EMC recommendations, what can be done to alleviate the handshake issue?

  A. Install 3 TCP offload engine card

  B. Install a second network interface card

  C. Upgrade the LAN

  D. Upgrade the network driver

  Correct Answer: B

• Question 203:

  A customer has a new EMC Avamar server with four 3.9 TB data nodes. This server is backing up two Avamar clients. The first client has 10 GB of RAM and two file systems. The first file system has 2 million files consuming .75 TB. The second file system contains 3 million files consuming 1 TB of space. The second client has 8 GB of RAM and one file system containing 4 million files is consuming 1.2 TB of space. Both clients will belong to the same backup group. How long will the steady state backup group be expected to run?

  A. 4 hours

  B. 5 hours

  C. 6 hours

  D. 9 hours

  Correct Answer: D

• Question 204:

  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. Garbage collection is not running causing new stripes to be created

  B. HFS check has found errors and has not been completing successfully

  C. A large number of backups have expired causing new, relatively empty stripes to be created

  D. Stripes contain more data and steady state has been achieved

  Correct Answer: D

• Question 205:

  B. Config: 150 MB DataminE. 5 GB Illuminator: 1 GB

  C. Config: 150 GB DataminE. 5 MB Illuminator: 1 GB

  D. Config: 150 GB DataminE. 5 GB Illuminator: 1 GB

  Correct Answer: B

• Question 206:

  A customer is interested in using Data Protection Adviser (DPA) for monitoring TimeFinder replication on their Symmetric arrays. After discussing the Recoverability Analysis features within DPA, they are interested in a proof of concept.

  A. Linux server running Oracle or iAnywhere

  B. UNIX or Linux server running iAnywhere

  C. Windows server running Oracle

  D. Windows server running iAnywhere or SQL

  Correct Answer: C

• Question 207:

  A customer is running the backup and recovery configuration shown in the exhibit. They added a new VMware cluster with 100 virtual machines. They are now experiencing slow backups at certain times.

  What should the customer have done prior to making changes to the configuration?

  

  A. Increase EMC NetWorker server memory

  B. Capture baseline performance of the backup environment

  C. Configure alert notification of the backup environment

  D. Add network cards to the EMC NetWorker server

  Correct Answer: A

• Question 208:

  You are having a preliminary discussion with a prospective customer. The customer would like to know the

  deduplication rates that are typically when running initial EMC Avamar backups for file system and

  database data.

  Which information should be provided to the customer?

  A. File System = 20% Database = 80%

  B. File System = 50% Database = 50%

  C. File System = 70% Database = 35%

  D. File System = 80% Database = 20%

  Correct Answer: C
