As a result, these questions will not appear in the review screen. You have an Azure Cosmos DB for NoSQL account named account1 that uses autoscale throughput. You need to run an Azure function when the normalized request units per second for a container in account1 exceeds a specific value. Solution: You configure the function to have an Azure Cosmos DB trigger. Does this meet the goal?

Options

• AYes
• BNo

Explanation

{"question_number": 10, "question_summary": "Can an Azure Cosmos DB trigger on an Azure Function fire when normalized RU/s exceeds a threshold?", "correct_answer": "B - No", "explanation": "The Azure Cosmos DB trigger for Azure Functions is powered by the Cosmos DB change feed, which emits events when documents are inserted or updated within a container. It is fundamentally a data-change trigger, not a metrics-based trigger. It has no awareness of RU consumption, normalized throughput, or any performance metric. It cannot be configured to fire when a throughput threshold is exceeded. To respond to metric conditions like high RU/s, Azure Monitor metric alerts (as in Question 9) are the correct mechanism. Therefore, this solution does not meet the goal.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
