AI-200 Security And Observability Practice Question

You are troubleshooting a custom LLM application deployed to an Azure Kubernetes Service (AKS) cluster. Requests are failing intermittently with HTTP 429 errors from Azure OpenAI. You need to implement a resilient observability and retry strategy using Azure Monitor. Which metric should you monitor to identify throttling?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Monitor the 'Requests' metric filtered by Response Code 429 and set up smart detection rules in Application Insights.

HTTP 429 errors correspond to rate limiting (Tokens Per Minute or Requests Per Minute limits exceeded). The 'Processed Prompt Tokens' and 'Generated Tokens' metrics along with Azure Monitor alerts on 'Requests' metric with dimension 'Response Code: 429' are standard.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Monitor 'Disk Queue Length' on the persistent volumes attached to the pods.
Why it's wrong here
Disk performance is unrelated to upstream API rate limiting.
✗
Monitor 'CPU Utilization' of the AKS pods running the client application.
Why it's wrong here
HTTP 429 is generated by the server due to rate limits, not client CPU exhaustion.
✓
Monitor the 'Requests' metric filtered by Response Code 429 and set up smart detection rules in Application Insights.
Why this is correct
Filtering requests by response code 429 directly tracks rate limiting occurrences.
✗
Monitor 'Network Outbound' bytes from the AKS cluster.
Why it's wrong here
Network metrics will not indicate API throttling behavior.
