NVIDIA AI Infrastructure Sample Questions (Q42-Q47):

NEW QUESTION # 42
For a 48-hour NCCL burn-in test, which parameters ensure sustained fabric stress while detecting silent data corruption?

A. broadcast_perf -b 4G -e 16G -w 100
B. all_reduce_perf -b 8G -e 32G -z 1 -G 1000
C. reduce_scatter_perf -f 2 -g 8
D. all_reduce_perf -b 8G -e 32G -c 1000 -z 1 -G 1000

Answer: D

Explanation:
all_reduce_perf with large message sizes sustains heavy fabric stress, while the validation/checking option helps detect silent data corruption during the burn-in. The long iteration count and GPU Direct usage keep the NCCL workload active long enough to expose intermittent fabric or data-integrity issues.

NEW QUESTION # 43
A financial institution deploys NVIDIA BlueField DPUs in a shared AI infrastructure where multiple business units use the same physical network. Security administrators want to isolate infrastructure services from tenant workloads while enforcing networking policies independently of the host operating system. Which BlueField capability best satisfies this requirement?

A. Infrastructure offload with isolated security and networking services on the DPU
B. Dynamic expansion of GPU framebuffer memory
C. Hardware acceleration for tensor operations during model training
D. Automatic GPU virtualization through CUDA

Answer: A

Explanation:
BlueField DPUs isolate networking, storage, and security functions from the host system by executing these services on dedicated Arm processors within the DPU. This architecture enhances security, enables infrastructure-level policy enforcement, and reduces dependence on the host operating system. BlueField does not virtualize GPUs, accelerate tensor computation, or increase GPU memory capacity.

NEW QUESTION # 44
An AI infrastructure team upgrades a training cluster from PCIe-only GPU servers to HGX systems with NVLink and NVSwitch. Single-GPU benchmark results remain unchanged, but multi-GPU training jobs complete significantly faster. Which workload characteristic most directly benefits from the new architecture?

A. Local NVMe read performance for training datasets
B. Frequent peer-to-peer communication and collective operations among GPUs
C. Kubernetes control plane scheduling latency
D. Sequential CPU-intensive preprocessing before model execution

Answer: B

Explanation:
NVLink and NVSwitch primarily improve communication between GPUs within the same server.
Workloads involving frequent gradient synchronization, tensor exchange, or collective operations benefit from the substantially higher bandwidth and lower latency compared to PCIe. CPU preprocessing, storage performance, and Kubernetes scheduling are largely unaffected by the GPU interconnect architecture.

NEW QUESTION # 45
Which of the following statements regarding the benefits of using a BlueField DPU for network offload are TRUE? (Select TWO)

A. Automatic compatibility with all existing network protocols without requiring software updates.
B. Increased network throughput due to hardware acceleration.
C. Simplified network configuration compared to traditional NICs.
D. Elimination of the need for a dedicated network interface card (NIC).
E. Reduced CPU utilization on the host server for network-related tasks.

Answer: B,E

Explanation:
BlueField DPUs offload network tasks, freeing up CPU resources and improving network performance through hardware acceleration. Simplified configuration is not always guaranteed, as DPUs often require more configuration due to their advanced features. DPUs do not eliminate the need for a NIC, they are a NIC with advanced processing capabilities.

NEW QUESTION # 46
What command is needed to measure BER (Bit Error Rate)?

A. ethtool -S<device>
B. mlxconfig -d <device> q
C. mlxlink -d <device> -c -e
D. msflint -d <device> q full

Answer: C

Explanation:
mlxlink -d <device> -c -e is used to inspect link status and extended physical-layer counters, including bit error rate information. This makes it the appropriate command for measuring BER on NVIDIA/Mellanox links.
