Backup Recovery Solutions Expert Exam for Technology Architects (E20-891) Free Practice Test

Question 1

EMC NetWorker is being proposed to a customer as a backup and recovery solution for a Microsoft SQL server.

B. Use NMSQL and set the recovery model property to Simple

C. Use NMDA and set the recovery model property to Simple

D. Use NMSQL and set the recovery model property to Full

Correct Answer: D

Question 2

A customer recently integrated EMC Avamar into their existing NetWorker datazone. After creating a deduplication client and defining the NetWorker deduplication node, the backup is started. However, the backup failed.
What must be done to perform a successful backup?

A. Create an AFTD on the Avamar server to store deduplication metadata

B. Create an AFTD to store the additional bootstrap information

C. Create an AFTD to store the deduplication indexes

D. Create a local AFTD on the storage node to store deduplication metadata

Correct Answer: D

Question 3

Which EMC Avamar feature provides the benefit of less network traffic than traditional backup applications?

A. Source-based deduplication

B. Inline deduplication

C. Post-process deduplication

D. Target-based deduplication

Correct Answer: D

Question 4

A customer has an EMC Celerra with 13 million files. The customer is using EMC NetWorker on Linux to run nightly full backups. If the average filename length is 64 bytes, what is the minimum /nsr/tmp size required?

A. 7832 MB

B. 5408 MB

C. 3856 MB

D. 4838 MB

Correct Answer: B

Question 5

Scenario 1
You have a customer with a large IBM Lotus Domino environment. The customer is in the process of migrating from a UNIX to a Microsoft Windows infrastructure. As part of this process, they are going to perform a refresh of the hardware and software that Domino is running on. In addition, they will migrate all client backups to a new EMC NetWorker environment. The new backup environment consists of a NetWorker server and two storage nodes running on Windows 2008.
The Domino environment consists of a single server running two instances of Domino. The total amount of data that needs to be backed up is approximately 900 GB. The Domino server will have connections to both the SAN and the LAN. They would like to perform hot backups of the databases using the NMDA but are leaving specific design decisions to you.
Additionally, the customer would like to send all data to disk for onsite backups and clone the first full backup of the year to tape for long-term offsite retention. The backup target infrastructure consists of a single Quantum i2000 tape library with six LTO-4 tape drives in addition to two EMC Data Domain 890s. One Data Domain will be located at their primary site. The second Data Domain is at the disaster recovery (DR) site as a replication target for the first.
One of the customer's major concerns is the backup speed of the Domino environment.
They are interested in any best practices they can implement to improve backup performance at the Domino level. Furthermore, they are looking for guidance in using NMDA to backup the data and leverage their backup infrastructure in the most efficient way.
Refer to Scenario 1.
The customer has decided to implement DAOS on both Domino instances. What is a requirement to ensure consistent recoverability of all data?

A. DAOS directory and the Domino databases must be backed up at the same time.

B. A resync of the DAOS repository must be performed prior to backup.

C. A level full backup must always be performed of the DAOS directory.

D. Domino index updates must be scheduled to occur immediately following the backup.

Correct Answer: A

Question 6

You are designing a backup solution for a large VMware environment. You are planning to use snapshot technology to backup the virtual machines but management has expressed concerns over how long the snapshots will take to create.
What is a way to reduce the time it takes to create a snapshot?

A. Ensure snapshots are taken of all datastores the virtual machine is using for virtual disks

B. Schedule the backups to occur when there is little I/O on the virtual machine datastore

C. Make sure at least 20% free space exists on the datastore where the virtual machine resides

D. Use Raw Device Mappings to ensure the backup server is able to have direct access

Correct Answer: B

Question 7

You have been assigned to resolve a customer's EMC VNX file-level backup design issue.
They are using EMC NetWorker with Data Domain as a LAN backup device. The IT infrastructure consists of LAN and SAN components.
Which solution provides the least amount of traffic over the production LAN and SAN?

A. Local backup with an NDMP tape server directly attached to a Data Domain VTL

B. Three-way backup to the Data Domain with a dedicated storage node

C. Local backup to the same VNX, then migrate it to a physically attached library

D. Copy the data to the SAN segment, then backup to the Data Domain

Correct Answer: A

Question 8

You are planning an MS SQL backup solution for a customer using EMC NetWorker and NMM without a proxy client. Which user privilege must be configured on NetWorker?

A. Add the NetWorker Administrator to the NMM remote user setting

B. Add the NMM client to the MS Windows administrators user group

C. Add the NMM client to the NetWorker Administrator user group

D. Add the NMM client to the Operators user group

Correct Answer: C

Question 9

An existing EMC Avamar customer would like to configure their Oracle servers to their Avamar backup environment. The environment consists of two standalone Oracle servers and one two-node RAC configuration.
In addition to installing the file system client on each node, what must be done to complete the configuration?

A. rac_config must be run on each node

B. Both cluster nodes must be registered with the Avamar server

C. rac_config must be run on one node in the cluster

D. Install the Avamar Oracle client on only one node in the cluster

Correct Answer: A

Question 10

An EMC NetWorker customer has asked you to deploy a Microsoft Exchange 2007 backup solution using NMM. They want single mailbox recovery capability.
What needs to be performed?

A. Ensure the RSG exists and add Receive-As Exchange extended rights to the NMM user.

B. Ensure the RSG system path and the RSG log path of the Exchange server are the same.

C. Ensure the RSG exists and take the Exchange database offline before the recovery operation.

D. Enable IPv6 on the Exchange server and disable Windows authentication.

Correct Answer: B
