質問 2

A potential customer requires 4 PB of usable capacity to store media files. Their data center has limited physical space, so efficient use of that space is important. However, the customer is concerned about using 3 TB or larger drives because of rebuild times.
How does a PowerScale cluster address this concern?

（A）OneFS protects data rather than rebuilding drives. Splitting drives into failure domains reduces risk.

（B）Drive recovery takes the same amount of time regardless of drive size. Short-stroking 4 TB drives to reduce drive seek and access time.

（C）Proactive hot sparing eliminates most drive rebuilds. Endurant Cache reduces the overhead during drive rebuild operations.

（D）Nodes have more drives per rack unit. Proactive hot sparing eliminates most drive rebuilds.

（B）SyncIQ license at source and target clusters. SnapshotIQ license at target cluster only.

（C）SyncIQ license at source cluster only. SnapshotIQ license at source cluster only.

（D）SyncIQ license at source and target clusters. SnapshotIQ license at source and target clusters.

質問 7

What form of journaling redundancy is provided by a PowerScale Gen6 cluster?

（A）Each node maintains a copy of the peer journal.
The local journal is saved on battery backed-up storage.

The local journal is saved on nonvolatile storage.

（C）In the event of a node failure, the peer journal is written to disk on the paired node.

（D）In the event of a node failure, the peer journal is written to nonvolatile storage on the paired node.

質問 12

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 OneFS enables each node to have a designated partner node for simple failover between the pair.

（C）Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.

（D）Isilon solutions can enable failover to other nodes with the use of client-side drivers.

質問 14

You have 1000 users for an application that reads and writes files averaging between one and four MB in size. Each user requires 24 MB of RAM. You want to add another 1000 users for this application, and in preparation for them, you run the isi statistics command.
You discover that the average CPU utilization is 20%; aggregate throughput averages 700 MB/s and the disk QueueD average is 1.5. Your cluster currently has five X200 (12 GB RAM, 1 TB drive) nodes, uses N+2:1 protection and 1 GigE networking.
What should you do to accommodate the next 1000 users?

（A）Add five additional X200 (12 GB, 1 TB drive) nodes

（B）Upgrade two of the 1 GigE NICs to 10 GigE on each node.

（C）Upgrade each X200 node to a total of 24 GB of RAM.

（D）Add five A100 (24 GB RAM) accelerator nodes.
