Question 220
During a security and capacity review at a financial analytics firm, engineers report the following issue: A feature schema changes in production while the training pipeline uses an older definition. 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.)
Explanation
Correct Answers
Correct corrective action. Connect model registry versions, deployment monitoring and controlled retraining decisions in the AI lifecycle instead of assuming a one-time training job ends operations. This fits the specific reported issue: A feature schema changes in production while the training pipeline uses an older definition. The corresponding failure being reduced is: Real-world data drift or quality degradation can go undetected if inference outcomes and model versions are not monitored after release.
Correct independent evidence. A new input distribution is detected, attributed to a model version and evaluated through an approved retraining and rollback process. 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
Not the most direct the action-and-evidence pair for these facts. Plan data collection, preparation, train and validation splits, experiments and versioned artifacts before production promotion so model behavior is reproducible. This choice concerns ai development lifecycle data and experiment tracking and may be valid in another design. But this case reports 'A feature schema changes in production while the training pipeline uses an older definition', which calls for reasoning about production mlops deployment and feedback loop. The targeted response is: Connect model registry versions, deployment monitoring and controlled retraining decisions in the AI lifecycle instead of assuming a one-time training job ends operations.
Not the most direct the action-and-evidence pair for these facts. Test questions requiring recent internal data return answers supported by the approved retrieved documents and respect access rules. This choice concerns natural language assistants and retrieval use cases and may be valid in another design. But this case reports 'A feature schema changes in production while the training pipeline uses an older definition', which calls for reasoning about production mlops deployment and feedback loop. The targeted response is: Connect model registry versions, deployment monitoring and controlled retraining decisions in the AI lifecycle instead of assuming a one-time training job ends operations.
Not the most direct the action-and-evidence pair for these facts. Identify NVIDIA NIM as a packaged optimized inference microservice option for deploying supported AI models with service APIs, and validate compatibility and endpoint behavior. This choice concerns nvidia nim inference microservices and may be valid in another design. But this case reports 'A feature schema changes in production while the training pipeline uses an older definition', which calls for reasoning about production mlops deployment and feedback loop. The targeted response is: Connect model registry versions, deployment monitoring and controlled retraining decisions in the AI lifecycle instead of assuming a one-time training job ends operations.
