QuestionQ412

Application Deployment and Security

A development team must create a new API that makes resources available to the open-source community. The API will be used on devices hosting captive portals, and thousands of people will use those portals each day. Which technique prevents the API from consuming excessive resources and keeps the captive portals able to perform their role promptly?

  • A token expiration
  • B pagination
  • C rate limiting
  • D throttling
Explanation

Rate limiting constrains the number of API calls allowed within a specified period, preventing traffic spikes or individual clients from overwhelming backend resources and preserving responsive service for other users. Microsoft documents rate limiting as a way to prevent overload and maintain consistent quality of service.
