AZ-204 Practice Question: Connect to and consume Azure services and third-party services

A developer exposes several backend APIs through Azure API Management. Clients must be throttled by subscription to protect the backend. What should be configured?

⚠ Common exam trap

Many exam-takers confuse telemetry or storage features (like Application Insights sampling or Blob soft delete) with API throttling mechanisms, overlooking that API Management's rate-limit and quota policies are the correct and direct solution for subscription-based throttling.

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

API Management rate-limit or quota policy

Azure API Management provides built-in rate-limit and quota policies that allow you to throttle client requests based on subscription keys. These policies enforce limits per subscription scope, protecting backend services from excessive traffic by rejecting requests that exceed the defined rate (e.g., requests per second) or quota (e.g., total calls per month). This directly addresses the requirement to throttle clients by subscription.

Answer analysis

Option-by-option breakdown

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

  • Blob soft delete

    Why it's wrong here

    Blob soft delete has no effect on API traffic.

  • Application Insights sampling

    Why it's wrong here

    Sampling reduces telemetry volume, not API traffic.

  • Private DNS zone only

    Why it's wrong here

    Private DNS resolves names but does not throttle clients.

  • API Management rate-limit or quota policy

    Why this is correct

    APIM policies can enforce rate limits and quotas per subscription or caller.
