Answer
D. Caches web pages and filters requests
Explanation
A proxy server improves performance by caching web pages and enforcing web filtering policies.
The main role of a proxy server is to cache web pages and filter requests.
A proxy server acts as an intermediary between client devices and the internet, forwarding requests and responses between users and web servers.
Caching: Proxy servers store local copies of frequently accessed web pages and files. When a user requests a cached resource, the proxy delivers it directly, reducing bandwidth usage and speeding up access times.
Filtering: Proxy servers can enforce web filtering policies by blocking access to specific websites or types of content, scanning for malware, and controlling which web resources users can access.
Additional benefits include providing anonymity by masking user IP addresses, optimizing bandwidth, and enhancing security through content inspection and access control.
Proxy servers are widely used in organizations to manage internet usage, improve network performance, and protect internal networks from external threats.
A proxy server improves performance by caching frequently accessed web content and enforces security and access policies by filtering user requests.
