NVIDIA AI Infrastructure NCP-AII Prüfungsfragen mit Lösungen (Q177-Q182):

177. Frage
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?

Antwort: A

Begründung:
TheQSA (QSFP to SFP Adapter)is a mechanical and electrical bridge that allows a single-lane SFP/SFP28 transceiver (typically 10G or 25G) to be plugged into a four-lane QSFP/QSFP28 switch port. In AI infrastructure, this is commonly used to connect low-speed management servers or legacy nodes to a high- speed backbone switch without wasting entire 100G/200G ports or requiring specialized breakout cables. The QSA adapter maps the single lane of the SFP module to the first lane of the QSFP port. This is a "pass- through" solution that maintains the signal integrity and latency characteristics of the link. It is the verified hardware solution for port-density mismatch in NVIDIA networking environments.


178. Frage
A system administrator notices a DGX A100 has lost a power supply, but the system is still operating at full performance. What is the minimum number of power supplies needed for the system to operate at full redundancy?

Antwort: B

Begründung:
DGX A100 systems require a minimum of four functioning power supplies to maintain full redundancy and full-performance operation. This allows the system to continue operating reliably even if a power supply failure occurs.


179. Frage
Consider a scenario where you are using NCCL (NVIDIA Collective Communications Library) for multi-GPU training across multiple servers connected via NVLink switches. Which NCCL environment variable would you use to specify the network interface to be used for communication?

Antwort: C

Begründung:
is the correct environment variable to specify the network interface used by NCCL. Is for Infiniband, and the other options are not directly related to specifying the network interface.


180. Frage
Refer to the exhibit. Which type of NVIDIA LinkX cable has a teal color code?

Antwort: A

Begründung:
NVIDIA LinkX teal-colored cables indicate active optical cables. AOCs use optical fiber with active circuitry in the cable ends to support high-speed, longer-distance data center interconnects.


181. Frage
You need to uninstall all NVIDIA drivers and associated packages from a Linux system cleanly. Which command sequence is the most reliable for achieving this after stopping the display manager (e.g., 'sudo systemctl stop gdm3')?

Antwort: A,C,D,E

Begründung:
The appropriate package manager command (like 'apt purge' , 'yum remove' , or 'dnf remove' with the 'nvidia- wildcard) is the most reliable for removing driver packages. If the driver was installed using the ' .'run' installer, running it with '-uninstall' is also effective. Directly deleting directories is not recommended as it may leave behind configuration files and dependencies. Always stop the display manager before uninstalling to avoid conflicts.
