create application consistent replicas of their MS Exchange databases using Microsoft
Volume Shadow Copy Service. The Storage Administrator asked for a review of the
command signals and data flows during the backup process. What are they?
A. VSS signals the VNX to initiate a copy
B. AppSync signals the VNX to initiate a copy
C. AppSync signals Exchange to freeze I/O
D. VNX signals Exchange when copy is complete
Answer: A
Question #7 (Topic: )
You have decided to use SAN Copy to perform an incremental copy migration of your
customer's data.
There are 25 source LUNs; each LUN is 250 GiB in size. The target LUNs are each 300
GiB in size.
Using best practices, what is the smallest sized LUN in GiB you should use in the reserved
LUN pool for this migration?

Question #8 (Topic: )
Your customer is planning to implement RecoverPoint for local replication. They have
several CLARiiON CX-4 arrays, two Celerras and a VNX array. They have the following
hosts in the environment: Windows (2003 and 2008), Linux and AIX. They also use
VMware. The customer wants to use host-based splitters
Which version of RecoverPoint should you recommend?

Question #9 (Topic: )
Your customer has established a new virtual pool of storage containing NL-SAS drives in a
RAID 5 configuration. Recently they have noticed that performance on the entire array is
affected between 1:00AM and 4:00AM.
What information would best indicate the root cause?

Answer: A
Question #10 (Topic: )
Click on the calculator icon in the upper left-hand corner.
Customer requirements call for a SnapView snapshot to be made of a clone prior to
resynchronization. The source LUN is 256 GiB, and performs 500 random reads/s and 25
random writes/s of 8 KiB. The clone will be fractured every 15 minutes, and resynchronized
after the snapshot is started.
How many COFWs will be performed each time the clone is resynchronized?
