EMC E20-329 Online Questions & Answers

• Question 41:

  A new Avamar customer is concerned with data security since all backup data is stored on disk. To minimize the customer's concerns, you have recommended the encryption-at-rest feature. What is a consideration when using this feature?

  A. Must be enabled at install time and results in noticeable performance reduction
  B. Can be enabled anytime and requires additional GSAN capacity
  C. Must be enabled on a per-client basis and has no impact on performance
  D. Must be enabled on a per node basis and requires the use of the consolidate option for backups
  A. Must be enabled at install time and results in noticeable performance reduction

• Question 42:

  An EMC NetWorker client is backed up as a guest in a virtual environment. This backup activity indirectly impacts other virtual machines (VMs) on the same ESX server that uses shared resources. What will reduce this impact?

  A. Define backup policies to limit concurrent jobs on the ESX server
  B. Reduce the frequency of incremental backups
  C. Create a group to back up a selection of VMs on the same ESX server
  D. Convert the client to a dedicated storage node
  A. Define backup policies to limit concurrent jobs on the ESX server

• Question 43:

  You are having a preliminary discussion with a prospective customer. The customer would like to know the deduplication rates that are typically seen 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%
  A. File system = 20%; database = 80%

• Question 44:

  The EMC account team has been asked to design a NetWorker backup solution. The customer's environment consists of a Microsoft Exchange Server 2007 Cluster Continuous Replication (CCR) deployment on a CLARiiON disk array with EMC VSS Provider and an EMC Disk Library.

  The customer wants to leverage the Microsoft VSS framework to back up their Exchange server from the Exchange Server 2007 CCR passive node. What needs to be considered when designing this backup solution?

  A. Backup from the Exchange Server 2007 CCR passive node will fail after Exchange Server 2007 CCR role change
  B. NetWorker Module for Exchange needs to be installed on both the Exchange Server 2007 CCR active node and passive node
  C. Exchange Server 2007 database and transaction logs must reside on the same volume
  D. Exchange Server 2007 system path and transaction logs must reside on separate directories
  A. Backup from the Exchange Server 2007 CCR passive node will fail after Exchange Server 2007 CCR role change

• Question 45:

  You are designing a backup solution for an EMC NetWorker customer. Given a conservative estimate, how many CPU cycles are needed by the storage node when backing up clients over the network to local tape drives at a rate of 100 MB/ s?

  A. 250 MHz
  B. 500 MHz
  C. 1000 MHz
  D. 2000 MHz
  C. 1000 MHz

• Question 46:

  Refer to Scenario

  EMC NetWorker, using a VADP proxy, is backing up 12 virtual machines concurrently. What is the total recommended additional RAM needed on the proxy?

  A. 6 GB
  B. 8 GB
  C. 10 GB
  D. 12 GB
  A. 6 GB

• Question 47:

  An EMC Avamar customer's Gen-1 system with 4 TB of GSAN capacity has reached read-only threshold. The customer indicates that the deduplicated backup data accounts for approximately 3.5 TB. What is the most likely cause for the read-only threshold being reached?

  A. Deduplication rate is less than expected, accounting for the remaining GSAN capacity
  B. Combination of system overhead, logs, and checkpoints account for the remaining GSAN capacity
  C. RAIN overhead accounts for the remaining available GSAN capacity
  D. Checkpoints and logs account for the remaining GSAN capacity
  C. RAIN overhead accounts for the remaining available GSAN capacity

• Question 48:

  Scenario

  A customer is looking to perform a data center refresh. They want to standardize their backup infrastructure by using EMC NetWorker, Avamar, and Data Domain in an integrated environment. The environment consists of:

  A primary data center - NetWorker server, Data Domain, and Avamar A disaster recovery (DR) data center - Data Domain only 220 remote sites Each remote site consists of approximately 30 clients and 1 storage node LAN speed at and

  between all sites is 1 Gb

  The company's Chief Technology Officer (CTO) has indicated that data must be backed up locally. Then, the data must be copied offsite to the primary data center and DR data center. The entire solution must be managed from a single

  unified interface in order to configure and track backup jobs.

  The company is subject to government regulations concerning data retention policies for confidential data. Data has to be retained for seven years on tape at the DR data center.

  In order for the backup administrator to copy the savesets from the remote Data Domain to the primary data center Data Domain, which replication method should be used?

  A. Clone Controlled
  B. Directory
  C. Root-to-Root
  D. WAAS
  A. Clone Controlled

• Question 49:

  You are assigned to upgrade an existing EMC NetWorker server. You ask the customer to run the nsrlic v servername command and send you the output. What information is received?

  A. Available licenses by type and client
  B. Available licenses by type and expiration date
  C. Number of licenses by client only
  D. Number of unassigned licenses
  A. Available licenses by type and client

• Question 50:

  You are asked to design an EMC NetWorker backup solution for a large Microsoft Exchange 2010 DAG environment. Their backup requirements are: Leverage Microsoft VSS to create consistent snapshots of Exchange mailbox database Keep the last two snapshots on the disk array for instant recovery Use NetWorker to schedule and manage the snapshots and roll the last snapshot over to a Data Domain system

  What is a design consideration?

  A. Exchange mailbox database and transaction logs need to be backed up at the same time
  B. Using NetWorker wizard to create client resources for all Exchange 2010 DAG members
  C. NetWorker save set should be set to 'All' to back up all Exchange 2010 DAG members
  D. Using an EMC VSS hardware provider for the rollover operation
  A. Exchange mailbox database and transaction logs need to be backed up at the same time
