質問 1：
A client has requested a new 4TB storage system. They need redundancy built in as well as some scalability. This should be attached to the current network, consisting of SAS and SCSI based servers, on a copper gigabit network. Low price is crucial. Which of the following would be the BEST solution?
A. Four independent 1TB NAS devices.
B. An iSCSI SAN containing five 1TB SATA drives in a RAID 5 configuration, with five empty slots for expansion.
C. Attaching a DAS to one of the existing servers, containing nine 300GB SAS drives in a RAID 5 configuration, with a hot spare drive.
D. A Fiber Channel SAN containing five 1TB FC drives in a RAID 5 configuration, with five empty slots for expansion.
正解：B
質問 2：
An administrator would like to employ a strategy to use SAN space more efficiently. Data that has a high I/O and is accessed often should be moved to SSD and Fiber Channel drives while data accessed less often should be moved to the higher capacity SATA drives. Which of the following features describes this strategy?
A. Storage base lining
B. SAN snapshot
C. Data tiering
D. Capacity planning
正解：C
質問 3：
