NCP-AII practice questions, page 6 of 7, with answer review and explanations.

Question 26

After configuring HA, the administrator runs cmsh status and notices the secondary head node reports mysql [FAIL]. What is the most likely cause?

  1. The secondary head node lacks NVIDIA GPU drivers.
  2. The BCM license expired after HA configuration.
  3. The cluster nodes are powered on during the HA configuration.
  4. Network connectivity issues between the primary and secondary head nodes.

Question 27

Why is it important to provide a large and high-performance local cache (using SSDs configured as RAID-0) for deep learning workloads on DGX systems?

  1. Using local SSD cache in RAID-0 enables direct GPU access to files without host CPU involvement, further boosting performance.
  2. Local SSD cache allows users to increase the number of NFS threads on the server without impacting storage reliability.
  3. A local SSD cache in RAID-0 ensures that most training data is read only once from the network, significantly reducing NFS traffic.
  4. Local SSD cache in RAID-0 is necessary to provide redundancy in case one of the drives fails during long training runs.

Question 28

What information does the “ibnodes” command display?

  1. All host & server names
  2. All hosts & switches
  3. All server names
  4. All channel adapters

Question 29

A system administrator needs to install a GPU/DPU in a server. The server has a free PCI-e slot, there are enough free PCI-e lanes, and there is enough room for the card. Which procedure should be followed?

  1. Ensure the server has enough power. Make sure the server is up and running with attached cables. Wear an ESD bracelet.
  2. Ensure the server has enough power. Verify compatibility of cables with server’s platform. Make sure the server is down to remove cables safely. Do not wear an ESD bracelet.
  3. Ensure the server has enough power. Verify compatibility of cables with server’s platform. Make sure the server is down to remove cables safely. Wear an ESD bracelet.
  4. Ensure the server has enough power. Make sure the server is down to remove cables safely. Wear an ESD bracelet.

Question 30

A cluster administrator needs to validate transceiver firmware versions across 200 ports using UFM. Which GUI-based method provides a consolidated view?

  1. Use “Topology” view to visually inspect cable icons.
  2. Navigate to “Devices” > select a switch > “Cables” tab to see ASIC firmware and transceiver versions.
  3. Export all switch logs and grep for “FW Version”
  4. Run mlxlink –d lid- -m on each port manually
