E20-329 Online Practice Questions and Answers

An EMC Avamar customer has a heavily utilized ESX system where CPU utilization is a concern. Each guest system, all of which are Linux, must be backed up with file granularity. The customer has both Avamar and NetWorker available and is looking to EMC for guidance

What is considered the most suitable approach to meet these requirements?

A. Install the Avamar agent directly on each guest system

B. Install the NetWorker agent directly on each guest system

C. Use Avamar VCB to offload the ESX server

D. Use NetWorker VCB to offload the ESX server

An EMC NetWorker customer is planning on directing the backups of a database server to the single-engine EMC Disk Library (EDL) as shown in the exhibit. The data to be backed up is accessed by the host through a redundant connection and resides on primary storage.

Based on EMC best practice, what needs to be adjusted in the solution?

A. Add a separate HBA to the dedicated storage node for EDL traffic

B. Replace the dedicated storage node with a standard storage node

C. Add a proxy host

D. Implement a second single-engine EDL for redundancy

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

An EMC NetWorker customer has recently added an Avamar system for file system backups. They want to move all backups to the Avamar system to take advantage of deduplication. They are currently backing up Sybase and SAP with NetWorker.

Which recommendation will meet these requirements?

A. Configure Avamar as a deduplication storage node in NetWorker and use deduplication for all backups

B. Use native database tools to back up to flat files, and then use Avamar to back up the resulting files

C. Use pre- and post-processing scripts to shut down the databases and perform a cold backup with Avamar

D. Use Avamar instead of NetWorker for all backups

A customer currently has a multi-node EMC Avamar solution with eight active storage nodes. They are currently at 85% GSAN capacity and receiving capacity warning messages. The customer would like to purchase additional capacity for the system.

What is a best practice for adding capacity?

A. Add two nodes

B. Add one node

C. No nodes can be added. Add a new Avamar system.

D. No nodes can be added. Migrate to a larger system.

In a customer's backup environment, EMC Avamar is integrated as a deduplication node with NetWorker. The customer wants to run multiple simultaneous backups from the same client.

What is the recommended maximum number of simultaneous streams?

A. 1

B. 2

C. 4

D. 6

A data center company is using two EMC NetWorker servers (NetWorker_A and NetWorker_B).

Each server has three storage nodes to protect 650 server applications and data.

The total amount of data being backed up is 100 TB. NetWorker_A server protects 60 TB and NetWorker_B server protects 40 TB.

To minimize cost and simplify licensing management for NetWorker, the company decided to switch from a traditional licensing model to a capacity licensing model.

How many licenses are needed to support the company's requirements?

A. 2 Source Capacity Datazone Enablers and 10 Tiered Capacity Entitlement license 10 TB Enablers

B. 2 Source Capacity Datazone Enablers and 650 Standard Client Connection licenses

C. 2 Base licenses and 10 Tiered Capacity Entitlement license 10 TB Enablers

D. 2 Source Capacity Datazone Enablers; one for 60 TB and one for 40 TB

A customer with 20,000 desktop/laptop (DT/LT) clients needs your guidance. They would like to determine what data to back up to their EMC Avamar DT/LT solution and what to exclude. They have the ability to recover any DT/LT OS with their in-house tools.

Based on best practices, what should be recommended?

A. Back up only user files/folders with the flag #USERDOCS#, and skip OS and non-business files

B. Back up the entire OS to take advantage of deduplication and Bare Metal Recovery

C. Back up user files/folders with the system-state flag and skip all music/video files

D. Back up the OS on a shorter retention time period and user files/folders on a longer retention time

A company has a large Oracle database and is using NetWorker Module for Databases and Applications for its backup. In this backup environment all the servers are impacted due to the huge volume of backup data.

Which solution would minimize the impact on the backup environment?

A. Back up only changed data instead of daily full backup

B. Include all database objects along with system tables

C. Use Microsoft VSS to create snapshots

D. Use Replication Manager along with the NMDA

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
