Explanation

A content filter (also called a web filter or URL filter) inspects traffic at the application layer and blocks or allows it based on content criteria such as keywords/words, threat signatures, and URLs. It is commonly used to prevent access to malicious sites, inappropriate content, or specific web categories. A Layer 2 switch (A) makes forwarding decisions based on MAC addresses and cannot inspect content. A load balancer (C) distributes traffic across servers for availability and performance. A traffic analyzer (D), such as a protocol analyzer or sniffer, captures and displays traffic but does not restrict it.
