EMC E20-329 Online Questions & Answers

• Question 31:

  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.

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

• Question 32:

  A customer has twofiles that have been locked and backed up to Data Domain appliance with the following parameters: File1=atime=20 years File1=atime=5 years The Data Domain global retention periods are configured as follows: Min=2 years Max=10 years The administrator changes the Data Domain maximum retention period to 4 years. After how many years can File 2 be deleted?

  A. 2
  B. 4
  C. 5
  D. 10
  C. 5

• Question 33:

• Question 34:

  An EMC Avamar customer is running a backup that is being written to a Data Domain system. The Data Domain cleaning runs at 8 M. on Tuesday mornings. Avamar maintenance runs daily at 6 M. A backup has completed successfully; however, it is no longer needed. The customer manually deletes the backup on Wednesday afternoon.

  When is the first opportunity for space to be reclaimed on the Data Domain system?

  A. At the next Data Domain file system cleaning
  B. Immediately on the Data Domain system
  C. At the next scheduled Avamar garbage collection
  D. When manually deleted from the Data Domain system
  A. At the next Data Domain file system cleaning

• Question 35:

  A long-term EMC SRDF customer wants to make their backups tapeless. The customer has asked for your recommendation on the bandwidth required for replication of 10 TB of daily backup data that is currently going to tape nightly. Bandwidth is provided by two OC-3 circuits between the source and target data center locations.

  Which information is needed to architect a solution for the customer?

  A. Available bandwidth, latency, and throughput objective
  B. Total bandwidth, trace route, and hops
  C. Circuit distance, line condition, and transmission rate
  D. Total bandwidth, latency, and compression rate
  A. Available bandwidth, latency, and throughput objective

• Question 36:

  The EMC account team has been asked to design a new EMC NetWorker backup solution for Microsoft Exchange Server 2007. The customer's environment consists of Microsoft Exchange Server 2007 hosted on an EMC CLARiiON disk array with EMC VSS Provider and an EMC Disk Library.

  Your design needs to include a server-less backup solution for the Microsoft Exchange Server 2007 environment by leveraging the Microsoft VSS framework. What is a recommended approach to meet the customer's requirements?

  A. NetWorker Module for Microsoft Applications
  B. NetWorker PowerSnap Module
  C. NetWorker Module for Microsoft Exchange Server
  D. NetWorker VSS Client for Microsoft Windows
  A. NetWorker Module for Microsoft Applications

• Question 37:

  An EMC Data Domain customer is evaluating new backup software and hardware for their environment. Their current environment consists of a single data center along with several remote sites.

  Their requirements are:

  Consolidate all backup hardware into their primary data center while still being able to perform remote backups. Continue to perform backups directly to tape for certain applications in order to send the tapes offsite for long-term retention.

  Keep their current Data Domain system as part of any new configuration. Optimize network performance without adding more hardware infrastructure. Manage the entire solution from a single unified interface.

  Which solution addresses these requirements?

  A. NetWorker with Data Domain Boost only
  B. NetWorker with Data Domain Boost and storage nodes at the remote sites
  C. Avamar with an integrated Data Domain system
  D. NetWorker with Data Domain VTL and an integrated Avamar system
  A. NetWorker with Data Domain Boost only

• Question 38:

  An EMC Avamar customer has added a new file system client to their moderately full Avamar single-node server. The single-node server is running in steady state and the initial backup is complete.

  What is the estimated time to backup this file server of 3 million files each night?

  A. Less than 1 hour
  B. 1 - 2 hours
  C. 3 - 4 hours
  D. 5 - 6 hours
  C. 3 - 4 hours

• Question 39:

  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
  B. Directory replication is running

• Question 40:

  When sizing an EMC Avamar or Data Domain solution, what are important challenges that should be taken into consideration?

  A. Data types, change rate, and growth rate
  B. Hardware type, change rate, and backup policy
  C. Data frequency type, and backup and restore policies
  D. Industry growth rate and deduplication ratio
  A. Data types, change rate, and growth rate
