質問 1：
You are tasked with connecting a new pair of hosts to an existing SAN infrastructure. The existing infrastructure is a 2Gb/s Fibre Channel solution on the far side of your facility. What are three concerns for the new infrastructure? (Choose three.)
A. The measured bit error rate (BER) is between "1 in 10^16" and "1 in 10^15"
B. Re-use of existing Gigabit Ethernet cable infrastructure since Gigabit Ethernet cables have the same specifications and limitations asFibre Channel.
C. Cable lengths as long as you measure and insure a proper strength signal as measured in D
D. Patch panels utilizing 50 micron optical cable for the long floor runs and 62.5 micron optical cable for the shorter patch panel to the server.
正解：B,C,D
質問 2：

D. Run reports on the storage utilization and IOPS components
正解：B,C
質問 3：
What is the primary objective of the storage capacity planning process?
A. To reach agreement with application representatives and management over the storage requirements.
B. To produce a capacity plan at agreed intervalswhich fits into the business planning cycle, e.g. the financial year.
C. To calculate the effects on ILM service levels, array and fabric utilization of the estimated demand over the period of the planning horizon.

質問 5：
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?
A. Create a COW snapshot every hour. Always keep three snapshots
B. Incrementally establish a split mirror snapshot every hour.Rortate using four snapshot volumes.
C. Create a COW snapshot every hour. Always keep four snapshots
D. Incrementally establish a split mirror snapshot every 45 minutes. Rotate using five snapshots volumes.
正解：C
質問 6：
A company needs to protect against data corruption using split mirror snapshots. Their RTO is 15 minutes and RPO is one hour. It takes 15 minutes to create an incremental split mirror snapshot. Which scenario fulfills their needs most efficiently?
A. Use one snapshot volume and incrementally establish it every 60 minutes.
B. Use one snapshot volume and incrementally establish it every 30 minutes.
C. Use two snapshot volumes and incrementally establish one volume every 30 minutes.
D. Use two snapshot volumes and incrementally establish one volume every hour.
正解：C
質問 7：
You have been tasked with designing an iSCSI based storage network that support 24 servers at a primary location attached to a 2TB storage array including a tape library with four tape drives. In addition, there are 18 branch offices each with at least one Windows server that eeds to gain access to primary storage, tape, and file sharing. Which two should be considered as part of his design? (Choose two.)
A. Look at available network bandwidth at primary location and to remote facilities and ability of currentnfrastructure to support more devices and bandwidth.
B. Determine if current switches support 802.11g and jumbo frames.
C. Upgrade the remote network to1Gb to every device and install iSCSI hardware adapters.
D. Assess network topology (bandwidth, available ports,current workload) and file server utilization and the onnectivity needs of storage and tape.
