Question 6

A customer has purchased a backup solution consisting of an EMC Avamar server with Data Domain integration to support Microsoft Exchange VSS backups. Test databases were created for the purposes of confirming end-to-end functionality.

B. The RDB information was missing.

C. The mail transaction logs were missing.

D. The mail transaction logs were invalid.

Correct Answer: B

Question 8

Click on the calculator icon in the upper left corner.
An EMC Avamar customer has an Avamar server with four 3.9 TB nodes. They are planning to add a new client to backup to this server. This client has 4 GB of RAM and two file systems. The first file system has 3 million files consuming .75 TB of space. The second file system contains 5 million files consuming 1 TB of space.

A. 5

B. 3

C. 4

D. 8

Correct Answer: D

Question 9

An EMC customer operating 24/7 has a single node 7.0 Avamar server at their remote site to back up their file servers. They recently implemented Data Domain to back up their large file servers and database servers.
They do not have DNS, and an iperf test shows they have 800 Mbps available bandwidth off their 1 Gbps LAN connection during backup hours.
Based on EMC best practices, what should you advise the customer?

A. Use separate DD Boost user accounts for each file server.

B. Use the FQDN name of the Data Domain system.

C. Upgrade the LAN bandwidth to 5 Gbps or higher.

D. Use the CIFS protocol to write the file server backups.

Correct Answer: B

Question 10

A. hl

B. c

C. cl

D. h

Correct Answer: B

Question 11
