The correct answer is C. Proxy server.
Explanation:
A gateway is a device that connects two or more different networks and is responsible for forwarding traffic between them. In this case, the server has been configured to act as a gateway between the LAN and an external network.
A proxy server is a networking device that acts as an intermediary between clients and servers. It receives requests from clients and forwards them to servers, and then receives responses from servers and forwards them to clients. This can provide benefits such as increased security and performance.
Increased security: A proxy server can act as a firewall by filtering out unwanted traffic and preventing unauthorized access to the internal network. It can also be used to block access to malicious websites and prevent malware from entering the network. In addition, a proxy server can provide anonymity for users by hiding their IP addresses and encrypting their traffic.
Increased performance: A proxy server can improve performance by caching frequently accessed resources. When a client requests a resource, the proxy server can check its cache to see if it already has a copy of the resource. If it does, it can return the resource to the client without having to fetch it from the server again. This can reduce latency and bandwidth usage, improving overall performance.
Load balancers are used to distribute traffic across multiple servers to improve performance and reliability. IDS (Intrusion Detection System) is a device that monitors network traffic for signs of malicious activity. Wireless controllers are used to manage and control wireless access points in a network.
In conclusion, a proxy server is the correct answer because it offers the ability to increase both performance and security by acting as an intermediary between clients and servers, filtering out unwanted traffic, caching frequently accessed resources, and providing anonymity for users.
