  What should be done to help the backup complete within the desired window without introducing locality or space reclamation issues?

  A. Reduce the file system cleaning throttle percentage
  B. Increase the file system cleaning frequency to twice per week
  C. Disable file system cleaning
  D. Perform manual file system cleaning daily
  A. Reduce the file system cleaning throttle percentage

• Question 63:

• Question 65:

  What does the EMC Data Domain file level retention locking feature provide?

  A. Active archive protection for IT governance
  B. Instant restoration of applications and data
  C. Built-in data safety for extended onsite retention
  D. Offline availability of archive data

• Question 66:

  What is an advantage of inline deduplication over post-process deduplication?

  A. Reduced time to disaster recovery readiness when replicating
  B. Disk cache tier ensures consistent write speed
  C. Increased deduplication from the use of variable segment sizes
  D. Write speed is increased by the number of disk spindles
  A. Reduced time to disaster recovery readiness when replicating

• Question 67:

  A customer has an EMC Data Domain integrated into their Symantec NetBackup domain as an OST device at their production site. They are installing a new NetBackup media server and a second Data Domain at their disaster recovery (DR) site to protect their client backup images.

  A. Configure NetBackup to duplicate the images between the Data Domain OST devices
  B. Configure MTree replication from the production site to the DR site
  C. Perform snapshots of the NetBackup image directories and replicate those snapshots to the DR site
  D. Use fastcopy at the production site to make a copy of the NetBackup images and replicate them to the DR site
  A. Configure NetBackup to duplicate the images between the Data Domain OST devices

• Question 68:

  An administrator wants to decrease the time needed to back up data to a locally connected EMC Data Domain system. In addition, the administrator wants to reduce the amount of network traffic generated by the backup software. Which DD Boost capability will achieve this requirement?

  A. Distributed Segment Processing
  B. Managed File Replication
  C. Advanced Load Balancing and Failover
  D. Low Bandwidth Optimization
  A. Distributed Segment Processing

• Question 69:

  An EMC Data Domain customer has been achieving a compression ratio of 14:1 for database backups over the past year. Two weeks ago the aggregate compression dropped from 14:1 to 4:1. What is a possible cause for this change in compression?

  A. User changed from single-threaded backups to multiplexed backups
  B. User changed from five backups per week to seven backups per week
  C. User changed the time backups start
  D. User changed from a 1 GB NIC to a 10 GB NIC

  B. Allows the user to mount and test recovery through NFS/CIFS when completed
  C. Allows the user to manually import the backup image to access the replicated copy
  D. Enables the backup software to change compression ratios at multiple sites
  A. Allows the backup software catalog aware access to the replicated copy
