EMC E20-329 Online Questions & Answers

• Question 81:

  A customer is currently running Data Protection Advisor. Over time, concerns have been expressed about performance degradation. After a complete review, you discovered that performance was being impacted due to data gathered by Collectors being maintained with configuration data.

  What is the most likely reason for keeping these two types of data separate?

  A. Dynamic nature and large size
  B. Static nature and large size
  C. Dynamic nature and small size
  D. Static nature and small size

• Question 82:

  A customer with 20,000 desktop/laptop (DT/LT) clients has expanded their custom set of includes/excludes for their Avamar DT/LT solution to cover all non- business files in their environment. Upon implementation of these datasets, they find that backups are not completing in the expected time frame. They need advice on managing their backups to fit the backup window.

  Based on best practices, what should be recommended?

  A. Minimize the number of includes/excludes and utilize the #USERDOCS# flag
  B. Increase the hash cache on all clients for faster processing of includes/excludes
  C. Move clients with the most includes/excludes into their own dataset and run this group first
  D. Move the includes/excludes to an Avamar flag file on each client for faster processing
  A. Minimize the number of includes/excludes and utilize the #USERDOCS# flag

• Question 83:

  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%
  C. File System = 70% Database = 35%

• Question 84:

  In an EMC Data Domain environment, what is a supported Extended Retention replication configuration?

  A. Collection replication from the active tier to the Retention Unit
  B. MTree replication directly to the Retention Unit on the target
  C. Collection replication from the GDA to the Retention Unit
  D. Directory replication from the GDA to the Retention Unit
  A. Collection replication from the active tier to the Retention Unit

• Question 85:

  A. 8
  B. 16
  C. 32
  D. 64
  C. 32

• Question 86:

  While designing an EMC Data Domain solution, you need to determine the required amount of storage capacity. The following information was gathered from the customer:

  2 TB full backup @ 5x compression 10% daily data change rate 4 incremental/week @ 10x compression 1x full per week @ 25x compression Retention period = 4 weeks with no data growth

  What is the minimum amount of storage needed to support this solution?

  A. 850 GB
  B. 900 GB
  C. 1040 GB
  D. 1200 GB
  C. 1040 GB

• Question 87:

  You are redesigning an EMC NetWorker customer's backup solution. Currently some of the file system clients are backing up to an Avamar deduplication node.

  The customer wants to back up these clients to a new Avamar deduplication node.

  What is an implication of this decision?

  A. New instance of each client must be created on the NetWorker server
  B. New full deduplication backup of each client is required
  C. Clients must first be retired on the old deduplication node
  D. All previously backed up data must first be replicated to the new deduplication node
  B. New full deduplication backup of each client is required

• Question 88:

  A customer wants to perform an EMC NetWorker Assessment on one data zone. What does the customer need to install for the quick scripts to execute on a Microsoft Windows platform?

  A. No additional software is required
  B. JAVA Runtime Environment
  C. Perl Scripts
  D. MySQL database
  A. No additional software is required

• Question 89:

  The EMC account team has been asked to design a NetWorker backup solution for a Microsoft Exchange server. 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 protect the Exchange Server 2007 CCR environment. What needs to be considered when designing a backup solution?

  A. Exchange server can be backed up from the Exchange Server 2007 CCR passive node
  B. Exchange server can only be backed up through a Proxy Node
  C. Microsoft Exchange Server 2007 database and transaction logs must reside on the same volume
  D. Microsoft Exchange Server 2007 system path and transaction logs must reside on separate directories
  A. Exchange server can be backed up from the Exchange Server 2007 CCR passive node

• Question 90:

  A potential EMC customer has a T1 circuit between their production data center and their disaster recovery data center that are 2,000 miles apart. They currently back up their Linux systems to physical tape using HP Data Protector. They back up an average of 20 TB each night.

  The customer wants a backup solution that improves backup and restore reliability, reduces overall costs, and eliminates physical tape. What is a recommended solution?

  A. Data Domain with replication over IP
  B. EMC Disk Library with Consolidated Media Management over FC
  C. EMC Disk Library with Remote Copy over IP
  D. Data Domain with OST and replication over IP
