質問 3：
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 5：
An error happened in the data center. According to ITIL principles, when is your job as storage administrator complete?
A. When the problem is fixed
B. When the problem is identified and the vendor is notified
C. When the cause of the error is determined
D. When a plan is developed to ensure the error does not reoccur
正解：D
質問 6：
When performing a strategic risk assessment of the storage infrastructure, you discover a risk scenario and have proposed several risk reduction strategies. Which two measurements differentiate the strategies? (Choose two.)
A. Cost of control
B. Optimal loss estimate
C. Risk transfer
D. Revised severity level
正解：A,D
質問 7：
Your SAN currently has eight server ports and eight disk ports on one 16 port switch. Each server port requires 80 MB/s of one-way bandwidth, spread out evenly among the storage devices. The customer would like to add 28 server ports along with 28 disk ports. Each server will evenly distribute its traffic on each disk. Using 16 port 1 Gb switches, which topology should you select to minimize the number of switches and ISLs required?
A. Star
B. Point-to-point
C. Core-edge
D. Full mesh
正解：C
