Question 1

A customer requires a high-availability SAN for disk access. The disk array and server may each

have multiple ports. How many Fabric switch ports are necessary for full redundancy in a network

with one disk array and one server? (Note: throughput is not a consideration.)

Answer : B

Question 2

Which statement is correct?

AFan-out is the ratio of switch ports to host ports, and indication of switch load at a single host port.

BFan-out is the ratio of storage ports to host ports, an indication of storage load at a single host port.

CFan-out is the ratio of switch ports to storage ports, an indication of switch load at a single storage port.

DFan-out is the ratio of host ports to storage ports, an indication of host traffic load at a single storage port.

Answer : B

Question 3

You notice, from continually monitoring a SAN arry, that an array has a number of soft SCSI bus error. You trace the errors back to a single drive using a vendor's event tool. Which two would correct this? (Choose two)

AYou should pull the drive out immediately and replace it to prevent data corruption on the
RAID set.

BSoft SCSI bus errors can be safely ignored as they do not actually denote any service requirements.

CYou should research the error to determine the impact and proper response including the vendor in these discussions

DReview the logs from the array to identify if there is a pattern of large numbers of these SCSI errors. A large number of these SCSI bus errors may denote a predictive failure.

Answer : C, D

Question 4

A company is designing a Disaster Recovery (DR) plan. They have an RPO of zero. The DR site

is located 250km from the production site. The DR plan must not affect application performance

at the production facility. Which scenario is appropriate?

AA new DR site must be chosen

BSynchronously replicated the data to the DR site

CAsynchronously replicated the data to the DR site

DCreate a split mirror snapshot and replicate the snapshot to the DR site

Answer : A

Question 5

Company.com needs to create a tape backup strategy for a file system. On average the file system will be 60% full. Array based virtualization will be used to create the snapshot, which will only be used for the tape backup. Write activity on the production volume will be minimal during the backup process. Which will provide the least impact to the production application?

ACOW snapshot mounted to a tutor/mount server.

BCOW snapshot mounted to the application server.

CSplit mirror snapshot mounted to a tutor/mount server

DSplit mirror snapshot mounted to the application server.

Answer : A

Question 6

Company.com needs to protect against data corruption. You must assume that it could take the company up to three hours to determine that their data is corrupted. They want to have a snapshot every hour. The production data is not write intensive. If a split mirror snapshot is used, incremental establishment takes 15 minutes. Which solution fulfils their needs and is the most cost effective?

ACreate a COW snapshot every hour. Always keep three snapshots

BCreate a COW snapshot every hour. Always keep four snapshots

CIncrementally establish a split mirror snapshot every hour. Rortate using four snapshot volumes.

DIncrementally establish a split mirror snapshot every 45 minutes. Rotate using five snapshots volumes.

Answer : B

Question 7

After lab testing a solution, which two deliverables should be presented to the implementation team? (choose two)

AList of tested and approved versioning and code

BPerformance metric showing maximum performance

CComplete TCO and ROI documentation for the solution

DTested procedures and process for failover and redundancy

Answer : A, D
