NCP-AII Practice Questions

A.  

Local SSD cache allows users to increase the number of NFS threads on the server without impacting storage reliability.

B.  

Using local SSD cache in RAID-0 enables direct GPU access to files without host CPU involvement, further boosting performance.

C.  

Local SSD cache in RAID-0 is necessary to provide redundancy in case one of the drives fails during long training runs.

D.  

A local SSD cache in RAID-0 ensures that most training data is read only once from the network, significantly reducing NFS traffic.

A.  

The command output is ignored if the system powers on without errors.

B.  

At least half of the GPUs report Status_Health = OK.

C.  

All GPUs report Status_Health = OK and Health = OK for each device.

D.  

Only the head node ' s GPUs need to be healthy.

A.  

Group nodes by function during initial setup and assign them to relevant categories in the cluster management tool.

B.  

Configure networking by validating all interfaces on each node, ensuring proper InfiniBand and Ethernet connectivity prior to installing cluster software.

C.  

Install Slurm on the head node and then configure the compute nodes’ default OS images.

D.  

Complete application containerization, run distributed jobs, and skip validation of node health or storage availability.

A.  

Switch from FP64 to FP32 precision.

B.  

Disable GPU affinity.

C.  

Reduce test duration to 12 hours.

D.  

Verify the matrix size is divisible by block size.

A.  

Run a read/write benchmark utility, such as FIO, across the RAID array, looking for expected speed and latency metrics as proof of storage integrity.

B.  

Verify that all configured RAID volumes are mounted and available in the operating system, and that disk utilization levels are within recommended limits.

C.  

Use the mdadm --examine and mdadm --detail commands to review the RAID array’s status, checking for drive failures, array consistency, and error events.
