Question 60

During a high-traffic model-service launch at an online commerce company, engineers report the following issue: The inference server queues requests to build huge batches during low traffic. The affected work supports product search, recommendations and fraud screening; peak request demand makes degraded predictions visible to customers. Select TWO: the most appropriate action and the strongest verification of that action. (Select TWO.)

  1. A representative image dataset is used to assess the selected vision task and error categories in realistic operating conditions.
  2. Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.
  3. Distinguish training with repeated forward and backward passes and model updates from inference that applies a trained model to new inputs, and size compute for the actual phase.
  4. Recognize multilayer neural representation learning as deep learning within machine learning and choose it when the data and task justify the added training complexity.
  5. Load testing reports end-to-end latency percentiles and completed requests per second at the intended concurrency and batch settings.

Explanation

Correct Answers

B:

Correct corrective action. Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target. This fits the specific reported issue: The inference server queues requests to build huge batches during low traffic. The corresponding failure being reduced is: Maximizing batch throughput without tracking queue delay can violate interactive inference latency even if GPUs appear busy.

E:

Correct independent evidence. Load testing reports end-to-end latency percentiles and completed requests per second at the intended concurrency and batch settings. This verifies the corrective approach for the affected product search, recommendations and fraud screening 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 representative image dataset is used to assess the selected vision task and error categories in realistic operating conditions. This choice concerns computer vision inspection and imaging use cases and may be valid in another design. But this case reports 'The inference server queues requests to build huge batches during low traffic', which calls for reasoning about inference latency throughput and batching tradeoffs. The targeted response is: Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.

C:

Not the most direct the action-and-evidence pair for these facts. Distinguish training with repeated forward and backward passes and model updates from inference that applies a trained model to new inputs, and size compute for the actual phase. This choice concerns training versus inference compute requirements and may be valid in another design. But this case reports 'The inference server queues requests to build huge batches during low traffic', which calls for reasoning about inference latency throughput and batching tradeoffs. The targeted response is: Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.

D:

Not the most direct the action-and-evidence pair for these facts. Recognize multilayer neural representation learning as deep learning within machine learning and choose it when the data and task justify the added training complexity.

Question 61

During a regulated deployment assessment at a healthcare imaging provider, engineers report the following issue: A product team reports GPU utilization without measuring user-visible request time. The affected work supports clinical imaging and model-assisted workflows; patient data constraints and reliable model performance are important. Which action most directly addresses the described requirement?

  1. Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.
  2. Distinguish training with repeated forward and backward passes and model updates from inference that applies a trained model to new inputs, and size compute for the actual phase.
  3. Connect model registry versions, deployment monitoring and controlled retraining decisions in the AI lifecycle instead of assuming a one-time training job ends operations.
  4. Select a GPU for many data-parallel numerical operations and a CPU for branching control or low-parallelism tasks, considering end-to-end bottlenecks.

Explanation

Correct Answer

Which acceptance result is most relevant to this workload?

  1. Load testing reports end-to-end latency percentiles and completed requests per second at the intended concurrency and batch settings.
  2. A pilot measures the contribution of data quality, model design and compute separately before attributing gains to a single factor.
  3. The plan separately estimates training memory and duration and measures inference latency or throughput using the same model family.
  4. An independent rerun identifies its dataset version, preprocessing choices, model checkpoint and held-out evaluation result.

D:

Not the most direct the action-and-evidence pair for these facts. Explain recent AI adoption through the combined availability of larger datasets, improved algorithms and architectures, scalable computing, and practical deployment tooling. This choice concerns data algorithms and model architecture advances and may be valid in another design. But this case reports 'A benchmark measures raw GPU kernels but excludes request serialization and queuing', which calls for reasoning about inference latency throughput and batching tradeoffs. The targeted response is: Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.

E:

Not the most direct the action-and-evidence pair for these facts. The supported framework detects the intended GPUs and successfully executes a representative operation using documented compatible versions. This choice concerns driver runtime and framework compatibility and may be valid in another design.
