A potential customer uses a solution from an EMC competitor for NFS storage in their main data center. The existing arrays are five years old, and the customer would like to consolidate them into a single new system.
The entire workload is generated by eight Linux hosts connected to the arrays that process video files. The customer informs you they are not able to collect performance information from the existing arrays.
Which tools can capture the workload requirements?
Response:

• A.netstat and esxtop
• B.MiTrends and netmon
• C.iostat and nfsstat
• D.Wireshark and sysstat

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?
Response:

• A.Upgrade two of the 1 GigE NICs to 10 GigE on each node.
• B.Add five A100 (24 GB RAM) accelerator nodes.
• C.Add five additional X200 (12 GB, 1 TB drive) nodes
• D.Upgrade each X200 node to a total of 24 GB of RAM.

• B.Single stream workflows, aggressive prefetching
• C.Multiple stream workflows, no prefetching
• D.Multiple clients accessing the same data; moderate prefetching

Which level of control does RBAC provide for cluster administration roles?
