Question 5
A customer has two files that have been locked and backed up to the Data Domain appliance with the following parameters:
File1 = atime = 20 years
File2 = atime = 5 years

Min = 2 years
Max = 10 years
The administrator changes the Data Domain maximum retention period to 4 years. After how many years can File2 be deleted?
- A. 2
- B. 4
- C. 5
- D. 10
Answer : C
Question 6
An EMC NetWorker customer has three backup servers with four storage nodes reporting to each of the backup servers. All servers run Microsoft Windows. A dual-engine EMC Disk
Library with Active Engine Failover is being proposed for this environment with embedded storage nodes for to physical tape.
What is a consideration for this solution?
- A. Active Engine Failover is unsupported in a Windows environment
- B. Multiple instances of the embedded storage node will need to be configured
- C. Each embedded storage node can only serve a single data zone
- D. NetWorker servers must be configured as read storage nodes for the cloning operation
Answer : B
Question 7
An EMC NetWorker customer has an Oracle database client. To achieve acceptable backup performance, they have configured the backup to use four RMAN channels.
The customer wants to benefit from adding Avamar deduplication for this backup. What is a consideration before proposing this design change?
- A. Data from each RMAN channel must be sent to a separate deduplication node
- B. Less than six RMAN channels in a deduplicated backup will perform poorly
- C. More than two RMAN channels in a deduplicated backup will cause the backup to fail
- D. Separate cache files are recommended for each RMAN channel
Answer : D
Question 8
A customer has a database server with 300 GB of Oracle database data. Using the default hash cache setting, what is the total amount of physical RAM required on the client?
- A. 250 MB
- B. 384 MB
- C. 3 GB
- D. 6 GB
Answer : D
Question 9
While running a three-month pilot using a Data Domain appliance, a customer produces the space utilization graph shown in the exhibit.
What does the saw tooth line for the compression ratio represent?
- A. Expiration of data
- B. Sanitization of data
- C. Retention of data
- D. Reclamation of data space
Answer : D
Question 10
The EMC account team has been asked to design a Network backup solution for a VMware
ESX3.5 environment with the following requirements:
1. Reduce workload on the ESX server during backups
2. Eliminate backup traffic from the LAN by moving data directly from the SAN
3. Support file-level backups for virtual machines running Microsoft Windows
What is a recommended backup solution?
- A. VMware service console backup
- B. VMware vStorage API backup
- C. VMware Consolidated Backup
- D. VMware guest backup
Answer : C
Question 11
You are redesigning an EMC NetWorker customer's backup solution. Currently some of the file system clients are backing up to an Avamar deduplication node. The customer wants to back up these clients to a new Avamar deduplication node.
What is an implication of this decision?
- A. New instance of each client must be created on the NetWorker server
- B. New full deduplication backup of each client is required
- C. Clients must first be retired on the old deduplication node
- D. All previously backed up data must first be replicated to the new deduplication node
Answer : B
Question 12
You are adding an Avamar deduplication node to a customer's EMC NetWorker environment. Clients currently back up to tape and perform full backups on Sunday and incrementals on all other days.
In the new solution, these clients will back up to the deduplication node. The speed of recovery is important to the customer. Which changes may be required to the backup schedule?
- A. Perform Full on Sunday and Level 1 backups on all other days of each week
- B. No changes are required to the backup schedule
- C. Perform initial Full backup and Level 1 backups forever
- D. Perform Full backups every day
Answer : D
Question 13
