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. A resync of the DAOS repository must be performed prior to backup.
• B. A level full backup must always be performed of the DAOS directory.
• C. Domino index updates must be scheduled to occur immediately following the backup.
• D. DAOS directory and the Domino databases must be backed up at the same time.

An EMC customer is currently backing up their Microsoft Exchange database to an EMC Avamar server. The backups are setup to full on Friday, skip on Sunday, and only transaction logs backed up the rest of the week. The customer would like to integrate Data Domain to Avamar and run the database backups to the Data Domain system.
If a Data Domain system is deployed on Sunday, which type of backup runs on the following Monday?

• A. Backups will be skipped
• B. Level 1 backup of the database
• C. Full database backup
• D. Transaction logs backup

A customer noticed that they have incorrectly configured their NetWorker Browse and Retention policies for all currently defined clients. This issue was discovered when a DPA report was e-mailed showing the amount of available space on their EMC Data Domain system.
The customer has made the necessary corrections to the Browse and Retention policies.
They have manually deleted save sets that should have been expired based upon the new Browse and Retention times. After comparing the size of the index directory, prior to and after the modification, the customer noticed that the index directory decreased in size by several hundred GB. However, the available space on the Data Domain remained unchanged.
Although NetWorker has deleted the necessary indexes, why does the Data Domain available capacity remain the same?

• A. Clients have deduplication references to the same data
• B. NetWorker Data Domain device has automatic retention set
• C. Data Domain retention lock is active
• D. NetWorker clean process was not run

Which environment will yield the optimal data deduplication for backup purposes?

• A. An advertising organization where multimedia files are backed up and stored indefinitely
• B. Virtualized environment where O/S images are stored in a SAN environment and backed up and retained for 3-6 months
• C. Hospital environment where compliance requires patient information (CAT scans, MRI, x-rays) to be backed up, stored, and accessible for up to 10 years
• D. Database environment where large transaction logs are backed up on a daily basis and stored for one month

An EMC Avamar customer regularly backs up their SharePoint distributed farm. They noticed that with the backup taken today, Avamar has listed the backup under a different farm name.
What is a possible cause?

• A. Backup was started from another web front-end server
• B. More than the recommended number of streams was specified in the backup
• C. One of the servers hosting a content database was not operational
• D. Web front-end server failed to discover the farm topology
