NVIDIA AI Infrastructure Sample Questions (Q190-Q195):

NEW QUESTION # 190
An administrator installs NVIDIA GPU drivers on a DGX H100 system with UEFI Secure Boot enabled. After reboot, the drivers fail to load. What is the first action to resolve this issue?

A. Delete /etc/X11/xorg.conf to force driver reconfiguration.
B. Reinstall drivers using apt-get install nvidia-driver-550 without rebooting.
C. Disable Secure Boot permanently in BIOS/UEFI settings.
D. Enroll the Machine Owner Key (MOK) during system reboot and enter the recorded password.

Answer: D

Explanation:
With UEFI Secure Boot enabled, NVIDIA kernel modules must be trusted before they can load.
Enrolling the Machine Owner Key during reboot and entering the recorded password completes the trust process so the signed NVIDIA driver modules can load successfully.

NEW QUESTION # 191
An InfiniBand server stops working, and a system administrator runs the "ibstat" command that provides the following output:

What is the cause of the issue?

A. The HCA port is faulty.
B. The cable is disconnected.
C. The neighboring switch port is faulty.
D. There is no running SM in the fabric.

Answer: D

Explanation:
The port shows Physical state: LinkUp, so the cable and physical link are up, but the logical State remains Initializing and SM lid is 0. In InfiniBand, a port typically remains initializing when no subnet manager is running or reachable to bring the port to the active state.

NEW QUESTION # 192
If two ports must be connected, but one is SFP and one is QSFP, for example, to connect a 25 GbE HOST CHANNEL ADAPTER to a QSFP port capable of both 100 GbE and 25 GbE, which of the following solutions would best meet this requirement?

A. SFP Connectors
B. QSA Adapter
C. SFP to 1G BASE-T (RJ45) adapter

Answer: B

Explanation:
A QSA adapter is used to connect an SFP/SFP28 transceiver or cable to a QSFP/QSFP28 port when the QSFP port supports the lower-speed mode. This fits the requirement of connecting a 25 GbE SFP-based host adapter to a QSFP port capable of operating at 25 GbE.

NEW QUESTION # 193
Which function is used to collect the cluster counters information?

A. PM
B. FM
C. GM
D. SM

Answer: A

Explanation:
The correct answer is PM, which refers to the Performance Manager or performance-management function used for collecting performance counter information from the InfiniBand fabric. In NVIDIA AI infrastructure, cluster counters are essential for troubleshooting and optimization because they expose link-level and port- level behavior across switches, HCAs, and fabric paths. These counters can include transmitted and received data, symbol errors, link errors, congestion indicators, XmitWait, packet drops, and other telemetry used to detect performance degradation. SM, or Subnet Manager, is responsible for fabric discovery, LID assignment, routing, and maintaining the logical InfiniBand subnet, but it is not primarily the performance-counter collection function. GM and FM are not the standard answers for collecting cluster counters in this context.
NVIDIA UFM Telemetry and diagnostic tooling collect and monitor InfiniBand port statistics such as bandwidth, congestion, errors, and latency, while UFM diagnostic output also includes PM counter dumps. In AI clusters, these counters help identify cabling faults, congestion, degraded links, and issues that can reduce NCCL and RDMA performance.

NEW QUESTION # 194
You are tasked with installing a DGX A100 server. After racking and connecting power and network cables, you power it on, but the BMC (Baseboard Management Controller) is not accessible via the network. You have verified the network cable is connected and the switch port is active. What are the MOST likely causes and initial troubleshooting steps you should take?

A. The BMC is faulty and needs to be replaced. Contact NVIDIA support for RMA.
B. The BMC IP address is not configured or is on a different subnet. Check the BMC's network configuration using the DGX's front panel or via serial console. Verify DHCP is enabled and functioning or manually configure a static IP address.
C. The BMC firmware is corrupted and needs to be reflashed using a USB drive. Check the DGX support site for the latest BMC firmware.
D. The network switch port is not configured for the correct VLAN. Verify the switch port configuration to ensure it is on the same VLAN as the BMC.
E. The BMC is not powered on because the main power supply is faulty. Verify the power supply LEDs are lit and providing power to the system.

Answer: B,D

Explanation:
The most likely causes are network configuration issues (incorrect IP, subnet, or VLAN). The BMC requires a valid IP configuration and network connectivity to be accessible. While other options are possible, they are less common as initial causes.
