Practice question from Azure API Management (AZ-204: Developing Solutions for Microsoft Azure Connect to and Consume Azure and Third-party Services), with the correct answer and a step-by-step solution.

medium · MCQ · Q-15388D

An API Management administrator wants to allow each subscription to make at most 100 calls every 60 seconds. Calls exceeding the limit should be rejected by the gateway. Which inbound policy statement meets this requirement?

  1. A.<rate-limit-by-key calls="100" renewal-period="60" counter-key="@(context.Subscription.Id)" />Correct answer
  2. B.<quota-by-key calls="100" renewal-period="60" counter-key="@(context.Subscription.Id)" />
  3. C.<validate-jwt header-name="Authorization" failed-validation-httpcode="429" />
  4. D.<set-header name="X-Rate-Limit" exists-action="override"><value>100</value></set-header>

Solution

The rate-limit-by-key policy limits short-term request rates and can use the subscription ID as the counter key. Once the limit is exceeded, API Management returns HTTP 429. A quota controls longer-term usage totals, while the other policies do not enforce request-rate limits.
