NEW QUESTION # 110
In your multi-tenant AI cluster, multiple workloads are running concurrently, leading to some jobs experiencing performance degradation. Which GPU monitoring metric is most critical for identifying resource contention between jobs?
Answer: B
Explanation:
GPU Utilization Across Jobs is the most critical metric for identifying resource contention in a multi-tenant cluster. It shows how GPU resources are divided among workloads, revealing overuse or starvation via tools like nvidia-smi. Option B (temperature) indicates thermal issues, not contention. Option C (network latency) affects distributed tasks. Option D (memory bandwidth) is secondary. NVIDIA's DCGM supports this metric for contention analysis.
NEW QUESTION # 111
In a data center, what is the purpose and benefit of a DPU?
Answer: D
Explanation:
A Data Processing Unit (DPU) is a programmable processor that offloads, accelerates, and isolates infrastructure workloads-like networking, storage, and security-from the CPU. This enhances performance, reduces CPU overhead, and improves security by segregating tasks, benefiting AI data centers. It doesn't handle backups or physical infrastructure directly, focusing instead on compute efficiency.
(Reference: NVIDIA DPU Documentation, Overview Section)
NEW QUESTION # 112
Which characteristic best describes inference when comparing inference to deep learning training?
Answer: C
NEW QUESTION # 113
Your AI data center is experiencing fluctuating workloads where some AI models require significant computational resources at specific times, while others have a steady demand. Which of the following resource management strategies would be most effective in ensuring efficient use of GPU resources across varying workloads?
Answer: C
Explanation:
Implementing NVIDIA MIG (Multi-Instance GPU) for resource partitioning is the most effective strategy for ensuring efficient GPU resource use across fluctuating AI workloads. MIG, available on NVIDIA A100 GPUs, allows a single GPU to be divided into isolated instances with dedicated memory and compute resources. This enables dynamic allocation tailored to workload demands-assigning larger instances to resource-intensive tasks and smaller ones to steady tasks-maximizing utilization and flexibility. NVIDIA's
"MIG User Guide" and "AI Infrastructure and OperationsFundamentals" emphasize MIG's role in optimizing GPU efficiency in data centers with variable workloads.
Round-robin scheduling (A) lacks resource awareness, leading to inefficiency. Manual scheduling (C) is impractical for dynamic workloads. Upgrading GPUs (D) increases capacity but doesn't address allocation efficiency. MIG is NVIDIA's recommended solution for this scenario.
NEW QUESTION # 114
When should RoCE be considered to enhance network performance in a multi-node AI computing environment?
Answer: B
Explanation:
RoCE (RDMA over Converged Ethernet) enhances network performance by offloading data transport to the NIC via RDMA, bypassing CPU involvement. It's particularly valuable when high CPU utilization limits bandwidth usage, as it reduces overhead and unlocks full link capacity.
While RoCE can handle storage traffic, it's less effective with high packet loss (requiring reliable networks), making CPU- bound scenarios its prime use case.
