NEW QUESTION # 61
What is an advantage of InfiniBand over Ethernet?
Answer: A
Explanation:
InfiniBand's advantage over Ethernet lies in its lower latency, achieved through a streamlined protocol and hardware offloads, delivering microsecond-scale communication critical for AI clusters. While InfiniBand often offers high bandwidth, Ethernet can match or exceed it (e.g., 400 GbE), and Ethernet supports RDMA via RoCE, making latency the standout differentiator.
(Reference: NVIDIA Networking Documentation, Section on InfiniBand vs. Ethernet)
NEW QUESTION # 62
Your AI team is using Kubernetes to orchestrate a cluster of NVIDIA GPUs for deep learning training jobs.
Occasionally, some high-priority jobs experience delays because lower-priority jobs are consuming GPU resources. Which of the following actions would most effectively ensure that high-priority jobs are allocated GPU resources first?
Answer: A
Explanation:
Configuring Kubernetes pod priority and preemption (B) ensures high-priority jobs get GPU resources first.
Kubernetes supports priority classes, allowing high-priority pods to preempt (evict) lower-priority pods when resources are scarce. Integrated with NVIDIA GPU Operator, this dynamically reallocates GPUs, minimizing delays without manual intervention.
* More GPUs(A) increases capacity but doesn't prioritize allocation.
* Manual assignment(C) is unscalable and inefficient.
* Node affinity(D) binds jobs to nodes but doesn't address priority conflicts.
NVIDIA's Kubernetes integration supports this feature (B).
NEW QUESTION # 63
Your AI team is deploying a multi-stage pipeline in a Kubernetes-managed GPU cluster, where some jobs are dependent on the completion of others. What is the most efficient way to ensure that these job dependencies are respected during scheduling and execution?
Answer: C
Explanation:
Using Kubernetes Jobs with Directed Acyclic Graph (DAG) scheduling is the most efficient way to ensure job dependencies are respected in a multi-stage pipeline on a GPU cluster. Kubernetes Jobs allow you to define tasks that run to completion, and integrating a DAG workflow (e.g., via tools like Argo Workflows or Kubeflow Pipelines) enables you to specify dependencies explicitly. This ensures that dependent jobs only start after their prerequisites finish, automating the process and optimizing resource use on NVIDIA GPUs.
Increasing job priority (A) affects scheduling order but does not enforce dependencies. Deploying all jobs concurrently with pod anti-affinity (C) prevents resource contention but ignores execution order. Manual monitoring (D) is inefficient and error-prone. NVIDIA's "DeepOps" and "AI Infrastructure and Operations Fundamentals" recommend DAG-based scheduling for dependency management in Kubernetes GPU clusters.
NEW QUESTION # 64
Why use NVIDIA GPUDirect Storage in an AI cluster?
Answer: A
Explanation:
NVIDIA GPUDirect Storage is used to create a direct data path between storage and GPU memory. NVIDIA' s GPUDirect Storage Overview Guide states: "GPUDirect Storage (GDS) enables a direct data path for direct memory access (DMA) transfers between GPU memory and storage, which avoids a bounce buffer through the CPU." It also says this direct path can relieve system bandwidth bottlenecks and reduce CPU latency and utilization load.
NVIDIA's GPUDirect Storage technical blog further explains that GPUDirect Storage enables "a direct data path between local or remote storage, like NVMe or NVMe over Fabric (NVMe-oF), and GPU memory." Therefore, the correct answer is C: it enables peer-to-peer memory transfers between GPUs and NVMe storage.
Why the other options are incorrect: GPUDirect Storage is not primarily about TCP/IP transmission between GPUs and CPUs. It does simplify and bypass parts of the traditional CPU-centric storage path, but the more precise answer is direct GPU-memory-to-storage transfer. It does not increase GPU clock rates.
Reference: NVIDIA GPUDirect Storage Overview Guide; NVIDIA Developer Blog - A Direct Path Between Storage and GPU Memory.
NEW QUESTION # 65
What NVIDIA tool should a data center administrator use to monitor NVIDIA GPUs?
Answer: C
Explanation:
The NVIDIA Data Center GPU Manager (DCGM) is the recommended tool for data center administrators to monitor NVIDIA GPUs. It provides real-time health monitoring, telemetry (e.g., utilization, temperature), and diagnostics, tailored for large-scale deployments. NetQ focuses on network monitoring, and there's no
"NVIDIA System Monitor" in this context, making DCGM the correct choice.(Note: The document incorrectly lists D; C is intended.) (Reference: NVIDIA DCGM Documentation, Overview Section)
