What is the purpose of the OPTIONS method in REST?
A) To describe the communication options for the target resource
B) To create a new resource
C) To retrieve a resource
D) To delete a resource
Answer:
A) To describe the communication options for the target resource
Explanation:
The OPTIONS method in REST is used to describe the communication options available for the target resource. When a client sends an OPTIONS request, the server responds with information about which HTTP methods are supported for the resource, what headers can be used, and other details relevant to the resource.
OPTIONS is often used in the context of CORS (Cross-Origin Resource Sharing) to determine what kind of HTTP requests the server will accept from different origins.
