Q. In the context of web protocols, what does SSL stand for?

A. Secure Socket Layer
B. Simple Socket Layer
C. Secure System Layer
D. Simple System Layer

Solution

SSL stands for Secure Socket Layer, which is a protocol for establishing a secure connection between a web server and a client.

Correct Answer: A — Secure Socket Layer

Q. What is the function of the 'Content-Type' header in an HTTP response?

A. To specify the server type
B. To indicate the type of content being sent
C. To define the encoding type
D. To manage cache settings

Solution

The 'Content-Type' header in an HTTP response indicates the media type of the resource being sent, allowing the client to understand how to process it.

Correct Answer: B — To indicate the type of content being sent

Q. What is the main function of the 'Cache-Control' header in HTTP?

A. To control the server load
B. To manage client-side caching
C. To specify the content type
D. To authenticate users

Solution

The 'Cache-Control' header is used to specify directives for caching mechanisms in both requests and responses, controlling how resources are cached.

Correct Answer: B — To manage client-side caching

Q. What is the primary purpose of the HTTP status code 404?

A. Server Error
B. Not Found
C. OK
