質問 1：
When using an N+2:1 protection policy on a 5-node Isilon cluster, how much capacity will be used to store a 320 KiB file?
A. 448 KiB
B. 640 KiB
C. 320 KiB
D. 576 KiB
正解：D
質問 2：
Where does SmartCache stage its write cache?
A. SSD
B. NVRAM
C. DISK
D. DRAM
正解：D
質問 3：
A customer plans to consolidate 200 TB of digital images and video content. Performance is important for recently created files. However, the customer wants any content that has not been accessed within 30 days to be stored in the cluster at a much lower cost because performance is no longer critical. Which Isilon configuration should be recommended?
A. S-Series nodes, X-Series nodes, and SmartPools
B. NL-Series nodes and SmartLock
C. X-Series nodes, NL-Series nodes, and SmartPools
D. X-Series nodes and SmartQuotas
正解：C
質問 4：
How does Isilon SnapshotIQ use storage for snapshots?
A. Works with 4 KiB blocks and will always use that amount of storage, no matter what has changed
B. Uses Changed Block Tracking and only saves the changed data blocks
C. Works on the file level and saves the entire file no matter what has changed
D. Uses Changed Block Tracking but always uses a 4 KiB block, even if the data changed is less than that amount
正解：B
質問 5：
What is the maximum volume or aggregate size that can be created with an Isilon Scale-Out NAS system?
A. 20 PB
B. 16 TB
C. 2.3 PB
D. 100 TB
正解：A
質問 6：
Traditional NAS storage architecture deploys simple two-way failover between two controllers in their storage systems, such as highly-available configurations. How is the Isilon architecture different in terms of system resiliency and availability?
A. Isilon OneFS enables each node to be a peer to any other node in an Isilon cluster.
B. Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.
C. Isilon OneFS enables each node to have a designated partner node for simple failover between the pair.
D. Isilon solutions can enable failover to other nodes with the use of client-side drivers.
