A data center is running a cluster of NVIDIA GPUs to support various AI workloads. The operations team needs to monitor GPU performance to ensure workloads are running efficiently and to prevent effectively? (Select two)
potential hardware failures. Which two key measures should they focus on to monitor the GPUs
A.
Disk I/O rates
B.
CPU clock speed
C.
GPU temperature and power consumption
D.
GPU memory utilization
E.
Network bandwidth usage
Correct Answer: C, D
Explanation:
To monitor GPU performance effectively in an AI data center, the focusshould be on metrics directly
tied to GPU health and efficiency: GPU temperature and power consumption(C) are critical to prevent overheating and power-related failures, which can disrupt workloads or damage hardware. High temperatures or excessive power draw indicate potential issues requiring intervention. GPU memory utilization(D) reflects how much of the GPU’s memory is being used by workloads. High utilization can lead to memory bottlenecks, while low utilization might indicate underuse, both affecting efficiency. Disk I/O rates(A) relate to storage performance, not GPU operation directly. CPU clock speed(B) is a CPU metric, irrelevant to GPU monitoring in this context. Network bandwidth usage(E) is important for distributed systems but doesn’t directly assess GPU performance or health. NVIDIA tools like NVIDIA System Management Interface (nvidia-smi) provide these metrics (C and D), making them essential for monitoring.

Question #2 (Topic: Demo Questions)
A large enterprise is deploying a high-performance AI infrastructure to accelerate its machine learning workflows. They are using multiple NVIDIA GPUs in a distributed environment. To optimize the workload distribution and maximize GPU utilization, which of the following tools or frameworks should be integrated into their system? (Select two)
In a distributed environment with multiple NVIDIA GPUs, optimizing workload distribution and GPU
utilization requires tools that enable efficient computation and communication: NVIDIA CUDA(A) is a foundational parallel computing platform that allows developers to harness GPU power for general-purpose computing, including machine learning. It’s essential for programming GPUs and optimizing workloads in a distributed setup. NVIDIA NCCL(D) (NVIDIA Collective Communications Library) is designed for multi-GPU and multinode communication, providing optimized primitives (e.g., all-reduce, broadcast) for collective operations in deep learning. It ensures efficient data exchange between GPUs, maximizing utilization in distributed training. NVIDIA NGC(B) is a hub for GPU-optimized containers and models, useful for deployment but not directly responsible for workload distribution or GPU utilization optimization. TensorFlow Serving(C) is a framework for deploying machine learning models for inference, not for optimizing distributed training or GPU utilization during model development. Keras(E) is a high-level API for building neural networks, but it lacks the low-level control needed for distributed workload optimization, it relies on backends like TensorFlow or CUDA. Thus, CUDA (A) and NCCL (D) are the best choices for this scenario. Reference: NVIDIA CUDA Toolkit documentation; NVIDIA NCCL documentation on nvidia.com
Question #3 (Topic: Demo Questions)
In an AI cluster, what is the purpose of job scheduling?
A.
To gather and analyze cluster data on a regular schedule.
B.
To monitor and troubleshoot cluster performance.
C.
To assign workloads to available compute resources.
D.
To install, update, and configure cluster software.
Correct Answer: C
Explanation:
Job scheduling in an AI cluster assigns workloads (e.g., training, inference) to available compute resources (GPUs, CPUs), optimizing resource utilization and ensuring efficient execution. It’s distinct from data analysis, monitoring, or software management, focusing solely on workload distribution.

Question #4 (Topic: Demo Questions)
Which NVIDIA tool aids data center monitoring and management?
A.
Mellanox Insight
B.
TensorRT
C.
Clara
D.
DCGM
Correct Answer: D
Explanation:
DCGM is the correct answer because NVIDIA DCGM stands for Data Center GPU Manager and is built for monitoring and managing NVIDIA GPUs in data center and cluster environments. NVIDIA’s DCGM documentation states that DCGM provides “continuous GPU telemetry at very low performance overheads” and provides mechanisms to gather, group, and analyze data at the job level.
NVIDIA’s DCGM documentation also states that DCGM-Exporter “allows users to gather GPU metrics and understand workload behavior or monitor GPUs in clusters,” exposing GPU metrics for monitoring tools such as Prometheus. Therefore, DCGM is the NVIDIA tool used for data center GPU monitoring and management. Why the other options are incorrect: TensorRT is for optimizing and running inference. Clara is NVIDIA’s healthcare and medical imaging platform. Mellanox Insight is not the primary NVIDIA data center GPU monitoring and management tool referenced for GPU operations; DCGM is.

Question #5 (Topic: Demo Questions)
How many Mellanox ConnectX-6 Single Port VPI cards are in a DGX A100 system?
The DGX A100 system includes eight Mellanox ConnectX-6 Single Port VPI cards, providing high-speed connectivity (up to 200 Gb/s) for clustering and data transfer. These cards support versatile protocols (InfiniBand or Ethernet), enabling robust multi-node AI workloads, with eight being the standard configuration for this system.
