質問 2：
You are configuring external storage with Hitachi Device Manager on a VSP. What happens when you set the Cache Mode parameter to Enable?
Response:
A. The VSP will always use the cache in the remote storage system for every operation.
B. After receiving the data into its cache memory,the VSP signals the host that an I/O operation has completed only after it has synchronously written the data to the external storage system.
C. The VSP will always use its cache for every operation.
D. After receiving the data into its cache memory,the VSP signals the host that an I/O operation has completed and then asynchronously destages the data to the external storage system.
正解：D
質問 3：

質問 4：
A VSP customer wants to optimize their multi-pathing environment and improve I/O performance.
Which two Hitachi Dynamic Link Manager (HDLM) features will assist this customer?
(Choose two.)
Response:
A. HDLM analyzes I/O profiles and determines the most appropriate buffering policy.
B. The HDLM server monitors the client hosts' multi-pathing agents and redistributes I/Os so no single path becomes overworked orunder-utilized.
C. HDLM spreads I/O workloads across available paths to ensure that no single path becomes overworked or under-utilized.
D. HDLM provides multiple load-balancing algorithms to balance I/Os across available paths.
正解：C,D
