Question 10

During a security and capacity review at a financial analytics firm, engineers report the following issue: The team confuses the CUDA runtime with the Kubernetes control plane. The affected work supports risk scoring and historical-data models; traceable controls and predictable throughput are required. Choose TWO: one corrective approach and one result demonstrating it works. (Select TWO.)

  1. A new input distribution is detected, attributed to a model version and evaluated through an approved retraining and rollback process.
  2. Check NVIDIA driver, CUDA runtime, framework build and GPU support together before choosing a software combination for an accelerated workload.
  3. Identify CUDA and a compatible driver and runtime as the GPU-compute programming stack, while keeping host orchestration distinct from parallel device kernels.
  4. A small parallel kernel runs on the GPU under a supported driver and the profiler distinguishes host control from device work.
  5. Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.

Explanation

Correct Answers

C:

Correct corrective action. Identify CUDA and a compatible driver and runtime as the GPU-compute programming stack, while keeping host orchestration distinct from parallel device kernels. This fits the specific reported issue: The team confuses the CUDA runtime with the Kubernetes control plane. The corresponding failure being reduced is: A GPU-equipped system will not accelerate unsupported code simply because a CUDA toolkit is installed; device execution and compatibility must be verified.

D:

Correct independent evidence. A small parallel kernel runs on the GPU under a supported driver and the profiler distinguishes host control from device work. This verifies the corrective approach for the affected risk scoring and historical-data models instead of treating an architecture diagram alone as success.

Incorrect Answers

A:

Not the most direct the action-and-evidence pair for these facts. A new input distribution is detected, attributed to a model version and evaluated through an approved retraining and rollback process. This choice concerns production mlops deployment and feedback loop and may be valid in another design. But this case reports 'The team confuses the CUDA runtime with the Kubernetes control plane', which calls for reasoning about cuda programming model for parallel applications. The targeted response is: Identify CUDA and a compatible driver and runtime as the GPU-compute programming stack, while keeping host orchestration distinct from parallel device kernels.

B:

Not the most direct the action-and-evidence pair for these facts. Check NVIDIA driver, CUDA runtime, framework build and GPU support together before choosing a software combination for an accelerated workload. This choice concerns driver runtime and framework compatibility and may be valid in another design. But this case reports 'The team confuses the CUDA runtime with the Kubernetes control plane', which calls for reasoning about cuda programming model for parallel applications. The targeted response is: Identify CUDA and a compatible driver and runtime as the GPU-compute programming stack, while keeping host orchestration distinct from parallel device kernels.

E:

Not the most direct the action-and-evidence pair for these facts. Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target. This choice concerns inference latency throughput and batching tradeoffs and may be valid in another design. But this case reports 'The team confuses the CUDA runtime with the Kubernetes control plane', which calls for reasoning about cuda programming model for parallel applications. The targeted response is: Identify CUDA and a compatible driver and runtime as the GPU-compute programming stack, while keeping host orchestration distinct from parallel device kernels.

Question 11

During a regional deployment expansion at a media technology business, engineers report the following issue: A workload reports a GPU but its compute library never launches device operations. The affected work supports language and visual-content AI services; different workloads compete for shared acceleration and storage. Which action most directly addresses the described requirement?

  1. Identify CUDA and a compatible driver and runtime as the GPU-compute programming stack, while keeping host orchestration distinct from parallel device kernels.
  2. Identify whether a task uses explicit programmed rules, learns statistical patterns from data or belongs to a broader artificial intelligence application before selecting an ML approach.

Question 12

During a regional deployment expansion at a media technology business, engineers report the following issue: A workload reports a GPU but its compute library never launches device operations. The affected work supports language and visual-content AI services; different workloads compete for shared acceleration and storage. Which acceptance result is most relevant to this workload?

  1. The approved artifact digest and component versions are traceable and reproduce the tested environment on another compatible host.
  2. A representative run measures host-to-device transfer, allocated GPU memory and kernel execution without exceeding supported memory limits.
  3. A small parallel kernel runs on the GPU under a supported driver and the profiler distinguishes host control from device work.
  4. A measured workload shows meaningful end-to-end speedup for parallel computation while the host still handles control and scheduling.

Explanation

Correct Answer

C:

Choose supported, versioned NVIDIA NGC containers or model artifacts and record their provenance and compatibility before deploying them to controlled environments. This choice concerns ngc catalog and managed ai software artifacts and may be valid in another design. But this case reports 'The cluster image includes a CUDA toolkit but no working GPU driver', which calls for reasoning about driver runtime and framework compatibility. The targeted response is: Check NVIDIA driver, CUDA runtime, framework build and GPU support together before choosing a software combination for an accelerated workload.
