Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 264

A developer deploys a web application in a local data center that is now experiencing high traffic load from users accessing data through REST API calls. Which approach enhances the responsiveness and performance of the API?

Answer options

• A. Ensure that all read requests are clearly identified by the PUT method.
• B. Configure API payload to return errors in HTTP 200 responses.
• C. Use HTTP POST or other non-read methods for read requests when possible.
• D. Use HTTP standard authorization header to submit authentication credentials.

Correct answer: D

Explanation

The correct answer is D because using the standard HTTP authorization header helps streamline the authentication process, which is crucial for performance under high load. Options A and C misuse HTTP methods, which can lead to confusion and inefficiency, while option B incorrectly indicates that errors should be sent with a successful status code, which is not a best practice.
