CompTIA Network+ N10-009 Practice Question

A Firewall is specifically designed to monitor and control incoming and outgoing network traffic based on predetermined security rules, making it the optimal choice for enhancing network security by preventing unauthorized access. In contrast, a Switch mainly connects devices within the same network to enable communication but does not provide advanced security features such as packet inspection. A Router directs data packets between different networks, focusing primarily on network traffic management rather than security enforcement. A Load Balancer distributes network or application traffic across multiple servers, primarily enhancing performance and reliability rather than security.
