• Question 313:

  The EMC account team has been asked to redesign a NetWorker backup solution. The existing backup environment consists of one NetWorker server and one storage node to back up approximately 80 clients. Over time, the amount of data increased, resulting in daily backups taking more than 24 hours to complete.

  Analysis has determined that the tape infrastructure and the network are not the bottleneck. What would you recommend to improve the backup performance with minimal costs?

  A. Add a storage node and balance the clients across the storage nodes

  B. Add an EMC NetWorker server and balance the clients across the EMC NetWorker servers

  C. Configure the existing storage node as a dedicated storage node

  D. Change the backup schedules so that they start as different times during the day

  Correct Answer: A

• Question 314:

  Which critical network elements are assessed by the Network Assessment Tool?

  A. Tracert, Ping, and Packet Loss

  B. Latency, Latency Jitterand Packet Loss

  C. Latency, Load, and Latency Jitter

  D. Latency, Latency Jitter, and Tracert

  Correct Answer: B

• Question 315:

  An EMC NetWorker customer performs all backups to physical. The customer backs up file systems,

  application servers, VMware guests multiple 10 TB database, and a large 20 TB NetApp filer. They have a

  primary and disaster recovery data center with an OC-12 circuit between the two sites.

  The customer's physical tape libraries are approaching end of support life and they are looking to replace

  them with deduplication technology. In addition, they want to improve NDMP backup times for their 20 TB

  NetApp filer.

  Which recommendation will address the customer's requirements?

  A. NetWorker deduplication for NDMP backups, databases, and application servers Data Domain for file systems and VMware

  B. NetWorker deduplication for file systems, VMware, and NDMPData Domain for databases and application servers

  C. NetWorker deduplication for file systems, application servers, and VMware Avamar for NDMPData Domain for databases

  D. NetWorker deduplication for NDMP Avamar for VmwareData Domain for databases, application servers, and file systems

  Correct Answer: D

• Question 316:

  A.

  

  B. C. D.

  Correct Answer: A

• Question 317:

  A customer has a Data Domain appliance that has reached 90% of maximum capacity. The customer does not want to purchase any additional storage.

  What will increase the average available capacity of the Data Domain appliance?

  A. Decrease the backup retention period

  B. Increase the snapshot expiration period

  C. Increase the number of streams

  D. Decrease the cleaning frequency

  Correct Answer: A

• Question 318:

  A customer is piloting a Data Domain appliance and notices that performance in the writing of backups is not optimal. Based on the System Show Performance metrics represented in the exhibit, which operation will provide the most improved the most improved performance?

  

  A. Reduce the read streams

  B. Suspend verification

  C. Disable cleaning

  D. Disable replication

  Correct Answer: A

• Question 319:

  A customer is using Data Protection Advisor (DPA) to monitor their backup environment. What is a benefit of using remote Collectors?

  A. Reduces the amount of information being transferred to the DPA server

  B. Collects system-related statistics for a given host

  C. Improves the collection performance of backup statistics

  D. Provides more complete backup reports

  Correct Answer: B

• Question 320:

  An EMC NetWorker customer wants to use the deduplication option. The requirement for a database server in their environment is to perform deduplication backups for file system data and NetWorker tape backups for database data. They want to allow a maximum of two parallel streams for file system backups and a maximum of four streams for database backups.

  How can this be accomplished?

  

  A. B.

  

  C. D.

  Correct Answer: C
