Which HTTP header indicates the type of content the server will respond with?

• A. Content-Type
• B. Accept
• C. Server
• D. User-Agent

Answer: (A)

The main idea here is how the server communicates what kind of data will be in the response body. The header that indicates this is Content-Type. It appears in the server’s response and specifies the media type, such as text/html; charset=UTF-8, application/json, or image/png, so the client can render or process the payload correctly. Other headers have different roles: Accept is sent by the client to say what content types it can handle, not what the server will send. The Server header reveals information about the server software, not the data format. The User-Agent header identifies the client making the request, again not the response content type.
