You review a Unisphere Analyzer report from a customer's EMC VNX. You observe that disk read activity

is higher than can be accounted for from host reads and normal pre-fetch activity.

What is the likely cause?

A. Writes on the array are reasonably sequential, but there is not enough data in cache to fill each stripe.

B. Individual writes are being requested and sequenced until the entire stripe is cached and parity is calculated before being written.

C. Disk crossings and stripe crossings are normal events where large I/O is involved.

D. The Unisphere Analyzer report was run against the wrong storage processor.

When creating a clone, what size must the clone be when compared to source LUN?

A. Half the size of the source LUN

B. Same size of the source LUN

C. Two times larger than the source LUN

D. Four times larger than the source LUN

A Storage Administrator would like to use MVM to create file systems for an application that requires exclusive access to the underlying drives. Another requirement is to distribute the load across as many drives as possible.

Which volume configuration is suitable for this type of application?

A. disk > stripe > meta

B. disk > meta

C. disk > stripe > slice > meta

D. disk > slice > stripe > meta

How many VNX arrays can be used to source replication volumes for a single RP/SE cluster using vRPAs?

A. One

B. Unlimited, as long as a license file is installed for each VNX

C. Two, with no constraints

D. Two, as long as the amount of data replicated does not exceed the amount licensed

Refer to the exhibit.

You are implementing a new VNX and you are considering whether or not to use FAST Cache. You decide to test the effect on response times with and without FAST Cache.

At what point in the graph do you consider the warm-up period to be complete?

A. C

B. B

C. D

D. E
