Show answer and explanation
Correct answers: A, B, E
Explanation
In REST-based APIs, HTTP verbs like GET, POST, PUT, and DELETE define the action to be performed. GET is used for retrieving data, while POST is used for creating or updating resources. For secure communication, OAuth is the preferred authentication method over Basic Authentication, as it provides better security and scalability.
- A. Correct.
Correct: HTTP GET is the standard HTTP verb used to retrieve data from a resource in REST-based APIs.
- B. Correct.
Correct: HTTP POST is used to create or update resources, such as modifying interface settings.
- C. Incorrect.
Incorrect: HTTP DELETE is used to remove a resource and is not suitable for retrieving data.
- D. Incorrect.
Incorrect: Basic Authentication is a less secure method and is not recommended for secure communication compared to OAuth.
- E. Correct.
Correct: OAuth is a modern and secure authentication method commonly used in REST-based APIs.
