Question #11 (Topic: )
A customer has four EMC Avamar servers located in a centralized disaster recovery site,
each receiving replicated data from several remote sites. Several client backups are in the
range of 1 - 4 TBs per dataset with file counts of 2 - 4 million files. Due to capacity
limitations, Avamar retention value is limited to two months and tapeout is being used to
provide extended retention of up to five years.
The nature of the customer's business requires frequent lookups of historical data, often
beyond the Avamar 2-month retention period. Therefore, quick recovery of files from tape is
required. Compliance requirements mandate tapeout be performed on a weekly basis. The
customer is considering Avamar Data Transport (ADT) or Avamar Tape Out (ATO).
Which tapeout solution is best suited for this environment?

customer is considering Avamar Data Transport (ADT) or Avamar Tape Out (ATO).
Which tapeout solution is best suited for this environment?
A. ADT for its file level recovery capabilities from tape and its ability to process several TBs per day
B. ATO due to its file level recovery capabilities from tape and its ability to process several TBs per day
C. ADT due to its ability to write deduplicated data to tape and its ability to process several TBs per day
D. ATO due to its ability to write deduplicated data to tape and its ability to process several TBs per day
Answer: B
Question #12 (Topic: )
Refer to Scenario 4.
What can be done to minimize the backup load on the clients with minimal resources?
What can be done to minimize the backup load on the clients with minimal resources?
A. Configure clients to backup 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. Ensure the metadata is sent to an AFTD on fast disk
Answer: A
Question #13 (Topic: )
An EMC NetWorker customer is backing up all file system clients to a deduplication node.
Over the past year, new file system clients have been added to the backup environment.
The customer wants to add another Avamar server and distribute the backup workload by
having some of the larger clients changed to back up to the new deduplication node.
What is the impact of this decision?

having some of the larger clients changed to back up to the new deduplication node.
What is the impact of this decision?
A. Clients backing up to the new deduplication node must run an initial full backup
B. Existing backups for these clients must be deleted from the old deduplication node
C. New client resources must be created on the NetWorker server
D. Clients must be deleted from the old deduplication node
Answer: A
Question #14 (Topic: )

B. /avamar220.lss.emc.com
C. /Clients domain
D. controlfile
Answer: A
Question #15 (Topic: )
A customer has an EMC Avamar system backing up a Celerra running DART 6.0 using a
single 36 GB NDMP Accelerator Node. They are also going to back up a VNX OE 7.0
system using the same NDMP Accelerator. Each NAS device has four volumes configured
on it. Backups will be configured on the Avamar system for both NAS storage devices to
start at the same time.
What will occur when the NDMP backups start using default settings?
