NEW QUESTION # 55
You are managing an AI training workload that requires high availability and minimal latency. The data is stored across multiple geographically dispersed data centers, and the compute resources are provided by a mix of on-premises GPUs and cloud-based instances. The model training has been experiencing inconsistent performance, with significant fluctuations in processing time and unexpected downtime. Which of the following strategies is most effective in improving the consistency and reliability of the AI training process?
Answer: D
Explanation:
Implementing a hybrid load balancer (B) dynamically distributes workloads across cloud and on-premises GPUs, improving consistency and reliability. In a geographically dispersed setup, latency and downtime arise from uneven resource utilization and network variability. A hybrid load balancer (e.g., using Kubernetes with NVIDIA GPU Operator or cloud-native solutions) optimizes workload placement based on availability, latency, and GPU capacity, reducing fluctuations and ensuring high availability by rerouting tasks during failures.
* Upgrading GPU drivers(A) improves performance but doesn't address distributed system issues.
* Single-cloud provider(C) simplifies management but sacrifices on-premises resources and may not reduce latency.
* Centralized data(D) reduces network hops but introduces a single point of failure and latency for distant nodes.
NVIDIA supports hybrid cloud strategies for AI training, making (B) the best fit.
NEW QUESTION # 56
Which NVIDIA software provides the capability to virtualize a GPU?
Answer: A
Explanation:
NVIDIA vGPU (Virtual GPU) software enables GPU virtualization by partitioning a physical GPU into multiple virtual instances, assignable to virtual machines or containers for accelerated workloads. Horizon is a VMware product, and "virtGPU" isn't an NVIDIA offering, confirming vGPU as the correct solution.
NEW QUESTION # 57
In a large enterprise cluster, frequent out-of-memory errors occur mid-experiment. What operational feature resolves this?
Answer: C
Explanation:
The correct answer is B because out-of-memory issues in shared AI clusters are typically addressed through workload resource management, reservations, and monitoring. NVIDIA Run:ai documentation states that workload management includes "Workload scheduling" to "prioritize and allocate GPUs based on workload needs" and "Monitoring and insights" to "track real-time and historical data on GPU usage to help track resource consumption and optimize costs." It also says NVIDIA Run:ai supports "Fractional GPU usage" so users can "request and utilize only a fraction of a GPU's memory, ensuring efficient resource allocation and leaving room for other workloads." This directly supports option B: resource reservation and usage monitoring in the workload manager.
Containers do not "boost" physical GPU memory, and simply increasing node count automatically does not correct the root cause if jobs are not requesting, reserving, or being monitored for the correct memory usage.
Reference: NVIDIA Run:ai Documentation - Overview, Workload scheduling, Monitoring and insights, Fractional GPU usage.
NEW QUESTION # 58
You are managing an AI infrastructure that includes multiple NVIDIA GPUs across various virtual machines (VMs) in a cloud environment. One of the VMs is consistently underperforming compared to others, even though it has the same GPU allocation and is running similar workloads.What is the most likely cause of the underperformance in this virtual machine?
Answer: A
Explanation:
In a virtualized cloud environment with NVIDIA GPUs, underperformance in one VM despite identical GPU allocation suggests a configuration issue. Misconfigured GPU passthrough settings-where the GPU isn't directly accessible to the VM due to improper hypervisor setup (e.g., PCIe passthrough in KVM or VMware)
-is the most likely cause. NVIDIA's vGPU or passthrough documentation stresses correct configuration for full GPU performance; errors here limit the VM's access to GPU resources, causing slowdowns.
Inadequate storage I/O (Option B) or CPU allocation (Option C) could affect performance but would likely impact all VMs similarly if uniform. An incorrect GPU driver (Option D) might cause failures, not just underperformance, and is less likely in a managed cloud. Passthrough misalignment is a common NVIDIA virtualization issue.
NEW QUESTION # 59
What is a significant benefit of using Slurm in high-performance computing (HPC) environments?
Answer: B
Explanation:
Slurm is a job scheduling system that efficiently allocates computational resources, manages job queues, and optimizes workload distribution in high-performance computing environments.
