NVIDIA AI Infrastructure Sample Questions (Q154-Q159):

NEW QUESTION # 154
Consider an AI server equipped with two NVIDIAAI 00 GPUs interconnected with NVLink. You want to maximize the memory bandwidth available to a CUDA application. You observe that the application's performance doesn't scale linearly with the number of GPUs. Which of the following coding techniques or configurations could potentially improve inter-GPU memory access performance?

A. Employ Unified Memory (I-JM) with prefetching to automatically migrate data between GPUs as needed.
B. Use CUDA-aware MPl for inter-GPU communication to leverage NVLink.
C. Ensure all memory allocations are performed on GPU O to minimize data transfer.
D. Disable NVLink to force the application to use PCle, which might provide more consistent performance.
E. Manually manage data transfers between GPUs using 'cudaMemcpyPeer' to exploit NVLink bandwidth. Choose the GPU with more free memory for allocations.

Answer: E

Explanation:
ScudaMemcpyPeer allows explicit, optimized data transfers between GPUs using NVLink. Unified Memory with prefetching can simplify development, but might not always provide the best performance. CUDA-aware MPl is typically used for inter-node communication, not intra-node GPU-GPU. Allocating all memory on one GPU defeats the purpose of multi-GPU acceleration. PCle will be slower than NVLink. Manually managing memory transfers, while complex, gives the programmer the most control over leveraging NVLink bandwidth.

NEW QUESTION # 155
You are installing multiple NVIDIA GPUs in a server for a deep learning cluster. To optimally utilize the GPUs, which software component(s) are MANDATORY after the physical installation and driver setup? (Select TWO)

A. NVIDIA CUDA Toolkit.
B. A text editor.
C. A deep learning framework like TensorFlow or PyTorch.
D. A web browser.
E. A spreadsheet program.

Answer: A,C

Explanation:
The NVIDIA CUDA Toolkit provides the necessary libraries and tools for GPU-accelerated computing. A deep learning framework (TensorFlow or PyTorch) is required to build and train deep learning models that leverage the GPUs. While a web browser and text editor might be useful, they are not mandatory. Spreadsheet applications have no purpose here.

NEW QUESTION # 156
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. reduce_scatter_perf -f 2 -g 8
C. all_reduce_perf -b 8G -e 32G -c 1000 -z 1 -G 1000
D. all_reduce_perf -b 8G -e 32G -z 1 -G 1000

Answer: C

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 # 157
You are tasked with setting up a secure environment for running GPU-accelerated machine learning workloads in Docker containers.
The security requirements dictate that containers should have minimal privileges and access only the necessary resources. Which of the following security measures are most relevant when using NVIDIA GPUs with Docker?

A. Regularly scan Docker images for vulnerabilities using tools like Clair or Trivy and rebuild images with patched dependencies.
B. Use AppArmor or SELinux profiles to restrict the capabilities of the Docker containers, limiting their access to system resources.
C. Grant the Docker containers direct access to the host's hardware devices, including the GPU, to maximize performance.
D. Implement network segmentation and firewalls to isolate the Docker containers from other services and the internet.
E. Run the Docker daemon in rootless mode to reduce the risk of privilege escalation.

Answer: A,B,D,E

Explanation:
Security is paramount, and minimizing privileges is key. Running Docker in rootless mode (A) reduces the attack surface. AppArmor/SELinux (B) confines container capabilities. Regular vulnerability scanning (C) helps prevent attacks based on known weaknesses. Network segmentation (E) limits the impact of a compromised container. Granting direct hardware access (D) increases the risk of privilege escalation and should be avoided in a secure environment. The NVIDIA Container Toolkit facilitates GPU access without requiring direct device passthrough, adhering to principle of least privilege.

NEW QUESTION # 158
A system administrator needs to install the NVIDIA Container Toolkit and perform the following actions:
- Update apt
- Issue the install command
- Configure the Docker daemon to recognize the NVIDIA Container Runtime
- Restart the Docker daemon to complete the installation.
What step should be taken first?

A. Initialize NVIDIA Omniverse configuration
B. Install SNAP package manager
C. Add NVIDIA Repository
D. Stop toolkit process

Answer: C

Explanation:
Before running apt update and installing the NVIDIA Container Toolkit package, the NVIDIA package repository must be added so the package manager can locate and install the correct toolkit packages.
