Question 5
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. The test database backups, using the Exchange VSS plug-in, complete successfully but they are being stored on the Avamar server instead of being sent directly to the Data Domain system.

- B. Test databases are smaller than 10 MB
- C. Avamar and Data Domain integration does not support the Exchange VSS plug-in
- D. Data Domain client plug-in was not installed on the test host
Answer : B
Question 6
An EMC customer wants to implement a backup solution for their virtual machines. They are interested in Avamar deduplication features. In addition, they want to minimize the backup capacity required. Their ESX environment is running optimally with sufficient resources.
Which VMware backup method will provide the most optimized capacity?
- A. VCB
- B. Guest level
- C. Image level with CBT
- D. Image level without CBT
Answer : B
Question 7
Refer to Scenario 6.
The customer has decided to add a second Data Domain server to HQ to meet database backup growth for Microsoft SharePoint which consists of many small databases. The customer advises you that HQ now has two Data Domain (DD)servers paired to the single
Avamar Gen4 server.
The disaster site has an integrated Avamar server with an expandable Data Domain server. However, the Avamar server is a single-node Gen4 that cannot be further expanded and is at capacity.
What must be done at the disaster recovery site to support replication from the HQ
Avamar/DD system?
- A. Migrate the Avamar server to a new multi-node server
- B. Expand the DD system and migrate the Avamar server to a new multi-node server
- C. Expand the DD system to match the second DD server at HQ
- D. Expand the DD system and install a second Avamar single-node
Answer : B
Question 8
An EMC Avamar customer is performing a Granular Level Restore of a SharePoint server.
They selected the "Restore everything to a different location" option and set "Absolute
Destination" to E:\. However, the restore has failed. What is a possible reason for this behavior?
- A. E:\ drive is already in use
- B. Everything must be restored to the original location
- C. Absolute Destination must be on a local hard drive
- D. SharePoint server is online
Answer : A
Question 9
An EMC Avamar customer wants to configure VADP to protect virtual machines at an image level. When attempting to add a vCenter server as an Avamar client, they receive an error. They have created the account on the vCenter server with proper permissions and verified the username and password are correct. Certificate Authentication has been disabled.
What is the most likely cause of this error?
- A. Data port 443 is not open between the Avamar server and vCenter system
- B. vCenter server does not have the Avamar agent installed
- C. VADP license has not been installed on the Avamar server
- D. GSAN has not been restarted after the certificate was disabled

- D. A separate set of cache files are created on the client for each channel
Answer : D
Question 14
An EMC customer has received a warning indicating that their Avamar server has crossed the 80% capacity threshold.
