• Question 292:

  You are recommending a NetWorker deduplication solution with Avamar for a current EMC NetWorker

  customer. The customer is planning to back up eight of their existing clients to the Avamar deduplication

  node.

  What is an EMC best practice when performing deduplication backups for these clients?

  A. Set the first backup level to Full

  B. Remove all client-side NetWorker directives

  C. Set the client parallelism value to 8

  D. Add the Avamar server name to each client's server file

  Correct Answer: A

• Question 293:

  A customer is considering the use of offsite physical tape vaulting rotation for compliance purposes. What is a key concern to discuss with the customer?

  A. Additional resources needed during the backup window for the production data

  B. Amount of tape media is twice as large as the actual production data size

  C. Inefficient tape media utilization when adhering to time-regulated timetables

  D. Media retention is always three times the length of the RPO value

  Correct Answer: C

• Question 294:

  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

  Correct Answer: D

• Question 295:

  A customer plans to integrate an EMC Disk Library (EDL) with NetWorker. The customer has purchased an Embedded Storage Node License to clone virtual taped from the EDL to a physical tape library. What should be included in the design document design to ensure the Embedded Storage Node reads the data from virtual tape during a clone operation?

  A. VTL Auto-changer resource needs the Embed Storage Node defined as the Read Host Name

  B. Client resource of the Embedded Storage Node needs the Embedded Storage Node defined as the Clone Storage Node

  C. Client resource of the NetWorker server needs the Embedded Storage Node defined as the Clone Storage Node

  D. Each backup client resource needs the Embedded Storage Node defined as the Clone Storage Node

  Correct Answer: A

• Question 296:

  You are designing a backup solution for an EMC NetWorker customer. Based on EMC best practices, how many CPU cycles are needed by the storage node when backing up clients over the network to local tape drives at a rate of 100 MB/s?

  A. 0.2 Hz

  B. 0.5 Hz

  C. 1.2 GHz

  D. 2.4 GHz

  Correct Answer: C

• Question 297:

  An EMC Avamar customer has a heavily utilized ESX system CPU utilization is a concern. Each guest system, all of which are Linux must be backed up with file granularity. The customer has both Avamar and NetWorker available and is looking to EMC for guidance What is considered the most suitable approach to meet these requirements?

  A. Install the Avamar agent directly on each system

  B. Install the NetWorker agent directly on each guest system

  C. Use Avamar VCB to offload the ESX server

  D. Use NetWorker VCB to offload the ESX server

  Correct Answer: B

• Question 298:

  An EMC NetWorker customer is considering using the deduplication feature with Avamar. What is a requirement when performing backups to a deduplication node?

  A. Deduplication backup metadata must be stored on tape

  B. NetWorker client host can only perform deduplication backups

  C. Deduplication node must be RAIN protected

  D. First backup to a deduplication node must be a Full backup

  Correct Answer: D

• Question 299:

  A customer has recently added a Celerra to their environment and has asked you to assess their current data protection methodology. They currently have an EMC NetWorker environment using an EMC Disk Library (EDL) as the primary backup location before they move the virtual tapes to physical tapes. How over, the rate of change of the data on the Celerra is too high for their RPO using the EDL for single file recovery if their backups are performed only at the end of the business day. What would you incorporate to lessen the impact of their once-a-day backup schedule on the Celerra data with minimal impact to their backup administration processes?

  A. Implement Snap Sure to make point-in-time copies of the file systems more frequently to recover individual files when requested ad perform full system backups at the end of the day

  B. Configure a local tape device on the primary Data Mover and use NDMP incrementally back up the file system more frequently than the once-a-day full backup

  C. Replicate the source data to a remote target using Replicator and use the target data as both file recovery and backup source

  D. Create an internal SVTLU on the primary Data Mover and use NDMP2D to incrementally back up the file system more frequently than the once-a-day full backup

  Correct Answer: A

• Question 300:

  A customer requires a backup host to be located at their primary data center and a tape library at their disaster recovery data center. The distance between the two data centers is 500 kilometers.

  What is the recommended connectivity solution between the data center and the tape library to address the customer's requirement?

  A. Fibre Channel-to-IP bridge or router

  B. Fibre Channel inter-swith link

  C. Dedicated Fibre Channel link

  D. Fibre Channel Arbitrated Loop

  Correct Answer: A
