EMC NAS Implementation Engineer Expert Exam v5.0
Question 1
Your customer would like to use ATA drives for their SnapSure SavVol. The I/O access pattern on the PFS is random read. They plan to access the checkpoints randomly as well.
What would you recommend?
- A. ATA drives provide good random I/O performance; therefore would be a good choice for checkpoint processing as well as checkpoint access.
- B. ATA drives provide good sequential I/O performance; therefore would not be appropriate for either checkpoint writes to the SavVol, or random access of the checkpoint.
- C. ATA drives provide good sequential I/O performance and are suitable for writes to a single SavVol. Random reads to the checkpoint would not be appropriate for ATA drives.
- D. ATA drives provide good random I/O performance which is important for copy-on-first- write activity; therefore would be appropriate for both checkpoint processing and checkpoint access.
Answer : C
Question 2
Which statement is true?
- A. Timefinder/FS is a volume oriented point in time copy using a Symmetrix/DMX Backend
- B. Near/FarCopy cannot be used in NSX00 environments but in all NSX00G environments
- C. FarCopy cannot use remote Timefinder/FS with a Symmetrix/DMX SRDF campus solution
- D. NearCopy uses Timefinder/FS in a SRDF campus solution and operates in synchronous mode
Answer : D

Answer : B
Question 6
You would like to run Celerra Replicator on one of your production file systems. You found from watching the last incremental backup that you have a change rate of 1% a day on that file system. The file system size is 1TB. You want to calculate the size of the SavVol to be able to continue with replication even if you have a 4 day network outage between the source and destination site. What size must the SavVol be to accommodate the changes?
- A. 400 MB
- B. 10 GB
- C. 40 GB
- D. 100 GB
Answer : C
Question 7
The customer would like to implement CAVA and a DHSM solution in his W2K3 environment. The customer is concerned about the time it takes to write a file to a DHSM drive on a secondary storage. What would you suggest to address this concern?

- B. Set the option for virusscanning to skip offline files
- C. Set the param "param cifs dhsm=1" on the Data Mover
- D. Disable network scan option on the customers virus scanner
Answer : B
Question 8
Acme Network Corp. is using Celerra Replicator. They are replicating five of their production critical FS to a remote datacenter. Because of the small backup window the
Storage Administrator decides to backup the file systems on the secondary site using
NDMP Backup. The NDMP fails to backup the remote file systems of IP Replication, but there is no problem backing up the source file systems. What needs to be done to correct the problem?
- A. NDMP Backup is not supported on the target site of a replication session
- B. Use LAN Backup to backup a remote file system belonging to a replication session
- C. Failover the production file systems to the remote site and back it up using NDMP on the remote site
- D. Create a checkpoint on the remote site and backup the checkpoint using NDMP backup on the remote site
Answer : D
Question 9
