Question 1

What is a consideration when designing an SRDF/A solution between a VMAX3 array and an older VMAX 40K array?

ASRDF/A will run in legacy mode.

BSRDF/A MSC is not supported.

CSRDF/A DSE is automatically enabled on both arrays.

DSRDF/A DSE pools must be configured on both arrays.

Answer : A

Question 2

What does the BCSD Write Load Adjustment Factor account for when designing SRDF solutions?

AI/O burstiness

BData compression

CI/O Locality of reference

DWrite folding

Answer : A

Question 3

A proposed SRDF/S solution was modeled with BCSD. The model assumed that the source array had 4 GigE ports. The RA Utilization chart shows the maximum utilization is at 70%.

How many GigE ports should be recommended to ensure a successful implementation?

Answer : C

Question 4

A proposed SRDF/S solution was modeled with BCSD. The model assumed that the source array had two RFs. The RA Utilization chart shows the maximum utilization is at 80%.

How many RFs should be recommended to ensure a successful implementation?

Answer : C

Question 5

Which benefit does SiRT provide for SRDF/S over Fibre Channel solutions?

ALatency is equivalent to one round trip.

BJitter is significantly reduced.

CUtilization of long distance links is improved.

DHigher data compression ratio can be achieved.

Answer : A

Question 6

What is the benefit of the Link Capacity Adjustment Scheme in an SRDF deployment over a SONET circuit?

AEnables dynamic scaling of bandwidth based on requirements

BEnables low capacity circuits to be grouped together into a higher capacity link

CAllows the replication throughput to scale linearly based on the TCP connections

DAllows multiple wavelengths of data to be transmitted over the same circuit

Answer : A

Question 7

You are designing an SRDF/S solution. Network bandwidth can be purchased in increments of single OC1 (52 Mb/s) links. Data compression is not in use. The workload profile is as follows:

Total I/Os per second = 30,000

Read block size = 4 KB

Write block size = 4 KB

Writes = 30%

How many OC1 links will provide sufficient bandwidth?

Answer : D
