  • B. DD VTL license is not installed and enabled
  • C. LAN speed is faster than the SAN speed
  • D. SAN zone is not properly configured


Answer : A

  • A. Clone-controlled
  • B. Directory
  • C. Collection
  • D. Archive


Answer : A

A customer had configured their EMC NetWorker environment to use Data Domain Boost,
CIFS, and NFS protocols to back up their local environment. After analyzing the performance of each protocol, the decision was made to only use the DD Boost protocol.

  • A. 1
  • B. 2
  • C. 3
  • D. 4


Answer : A

An EMC NetWorker customer has asked you to deploy a Microsoft Exchange 2010 backup solution using NMM. They have two Microsoft Exchange 2010 servers in a Database
Availability group (exch2010a and exch2010b). The client resource for 'exch2010a' is shown in the exhibit.


Which Exchange databases are backed up?

  • A. MDB01, MDB02, and MDB03
  • B. MDB01, MDB02, and MDB05
  • C. MDB01, MDB02, MDB05, and MDB06
  • D. MDB03, MDB04, and MDB06


Answer : B

An EMC NetWorker customer has an 8 TB Oracle database. They want to know the most efficient way to backup with NetWorker to Data Domain deduplication.
When integrating NetWorker with Data Domain, what is an Oracle best practice?

  • A. Limit the number of streams per channel to one
  • B. Limit the number of incremental backups
  • C. Use at least eight concurrent backups sessions
  • D. Use encryption and compression


Answer : A

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 willhave 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.
Which additional piece of information must be specified on the command line when using nsrdasv to manually perform backups of the Domino instances?

  • A. Path to the NMDA Lotus configuration file
  • B. Name of the Domino instance to be backed up
  • C. Level at which the backup should be performed
  • D. Path to the Domino installation files

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 level full backup must always be performed of the DAOS directory.
  • C. A resync of the DAOS repository must be performed prior to backup.
  • D. Domino index updates must be scheduled to occur immediately following the backup.


Answer : A

Scenario 6 -
A customer recently implemented an EMC Avamar solution in their primary data center.
The environment consists of several Microsoft applications, including Microsoft SharePoint,
Exchange, and SQL. An EMC Data Domain system was also deployed behind Avamar as the backup destination for these applications. There are also several file system clients that have been configured to back up directly to the Avamar server.
One Avamar server and two Data Domain systems have been deployed to support this configuration. The Avamar server is operating close to full capacity and there is no room for expansion since it is already fully provisioned with the maximum number of nodes. The
Data Domain systems have plenty of capacity left; each system is currently at 35% of utilization.
Refer to Scenario 6.
The customer needs to protect a number of new file system clients. How can this be accomplished?

  • A. Deploy a second Avamar server and configure the new clients on the new server
  • B. Direct their backup data to the Data Domain systems
  • C. Change the compression algorithm from lz to gz, freeing up space for the new clients
  • D. Increase the garbage collection frequency on the Avamar server
