An EMC customer has NetWorker integrated with an Avamar deduplication node, which is also replicating to the Avamar disaster recovery node. The auto recovery operation failed from the replica during the recovery of a Windows 2008 client. EMC support suggested to use the "RECOVER_FROM_REP_HOST=Yes" environment variable. The customer recovers the data successfully.
Where will this environment variable be set?
A. Windows 2008 client
B. Avamar deduplication node
C. Avamar replication node
D. NetWorker server
A current EMC NetWorker customer is backing up a mix of Microsoft Windows and Linux servers in their environment. They have decided to integrate two Avamar servers into their environment as deduplication nodes.
Clients will be configured to back up to the first node with Avamar replication configured between the two. Remote office backups will be performed over a WAN connection with limited bandwidth. Additionally, many of the backup clients are
on older hardware. This requires that the load increase by backups on the clients be minimized as much as possible.
What can be done to minimize the backup load on the clients with minimal resources?
A. Configure clients to back up with only a single stream.
B. Increase the size of the Avamar cache files on the clients.
C. Use a larger number of smaller savesets for the clients.
D. Configure clients to back up faster by using more streams.
A customer has installed EMC NetWorker with Avamar as its device for deduplication disk storage. The administrator is setting up a NetWorker client for a Microsoft Windows 2008 SP2 server to backup to their Avamar system. Which process is responsible for the bulk of the deduplication processing on the client?
A. nsravtar
B. nsravamar
C. nsradmin
D. save

In the event that the primary deduplication node has failed and is unreachable, what will happen if a restore is initiated?
A. Recovery will be automatically performed from the replication target.
B. Recovery will fail, reporting the deduplication node as unreachable.
C. Recovery will wait until the deduplication node comes online.
D. Recovery will fail, reporting that the client must first be activated on the replication node.
An EMC customer has NetWorker integrated with an Avamar deduplication node. They want to size the AFTD for storing metadata for 800 million files from various client backups. Based on EMC best practices, what is the recommended AFTD size?
A. 800 MB
B. 800 GB
C. 1,600 GB
D. 2 TB
An EMC NetWorker customer plans to implement deduplication for their file server backups. They are currently keeping their monthly backups for one year and daily backups for 1 month. They want to keep the same retention for daily and monthly backups. In addition, they need monthly backups stored on tapes.
Which cost effective solution would you recommend that the customer install?
A. Avamar deduplication node only
B. Avamar deduplication node and media access node
C. Avamar with ADT
D. Avamar Virtual Edition with Tapeout
An Avamar 7.0 file system client is running on limited RAM. The backup administrator notices that the client RAM is paging during its daily backups. Currently, the client is using default settings. Which avtar flag can be adjusted to reduce the RAM used?
A. Decrease the value of --cache-max-pages-resident.
B. Increase the value of --cache-page-size.
C. Decrease the value of --filecachemax.
D. Increase the value of --cache-musthave-threshold.
An EMC Avamar administrator upgraded a client to version 7.0 and performed a new backup of the client. What is the impact on the cache files?
A. Entries from f_cache.dat were migrated to f_cache2.dat
B. Demand-paging is used for the p_cache by default
C. Monolithic caching is used on both cache files
D. Demand-paging is used for p_cache2.dat only
An EMC Avamar backup administrator notices that the file cache on a backup client is under-sized. The client is using the monolithic caching strategy for the file cache. What rule is used to size the file cache?
A. N x 44 MB x 2, where N is the number of millions of files in the backup
B. N x 44 MB x 4, where N is the number of millions of files in the backup
C. N x 44 MB x 2, where N is the number of millions of files in the restore
D. N x 44 MB x 4, where N is the number of millions of files in the restore
An EMC Avamar administrator has used avtar to set hashcachemax to 96 MB. What is the size of the database to be backed up, in gigabytes?
A. 42
B. 48
C. 84
D. 96
