What action does a POST request typically perform?

• A. Updates existing resources
• B. Removes resources from the server
• C. Creates a new resource on the server
• D. Retrieves data from the server

Answer: (C)

A POST request is specifically designed to create a new resource on the server. When a client sends a POST request, it typically includes data that instructs the server to create a new entry based on that information. This is in line with the conventions of RESTful APIs, where POST is the method used to submit data to be processed or to create a new resource. For instance, when you fill out a form on a website to create a new user account, and hit the submit button, a POST request is sent to the server with the information you provided. The server processes this request and creates a new user resource in its database, corresponding to the data sent. The other actions mentioned in the options distinguish themselves with different HTTP methods. For example, updating resources is typically performed using the PUT or PATCH methods, while removing resources from the server is done using the DELETE method. Retrieving data is accomplished using the GET method, which is solely for fetching existing data without altering anything on the server. Thus, the nature of a POST request aligns perfectly with the creation of new resources.
