Question

A) Firewall server
B) Proxy server
C) DNS server
D) Mail server

Answer 1

A proxy server intercepts all messages between a client and a server to prevent hacking attacks and provides an extra layer of security.

Step-by-step explanation:

The correct answer is B) Proxy server.

A proxy server intercepts all messages between a client and a server and acts as a middleman, forwarding the requests from the client to the server and the responses from the server to the client. It can help prevent hackers or intruders from directly accessing the network by hiding the IP address of the client and adding an extra layer of security.

For example, if a user wants to access a website, the client sends the request to the proxy server instead of directly connecting to the website's server. The proxy server then forwards the request to the website's server and relays the response back to the client. This way, the client's IP address is kept hidden and the proxy server can filter out any malicious traffic or attacks.
