A cyber-security analyst is implementing a new network configuration on an existing network access layer to prevent possible physical attacks. Which of the following BEST describes a solution that wou

Implementing port security with one MAC address per network port effectively prevents unauthorized devices from gaining network access when connected to a legitimate port. This solution is relatively simple to deploy on existing switches, causing fewer issues compared to broader network authentication or architectural changes.

Deploying Network Access Protection (NAP) with DHCP and dynamic VLANs involves significant configuration of servers, clients, and network infrastructure, likely causing more deployment issues.

Configuring 802.1X and EAPOL requires a RADIUS server, client supplicants, and extensive network configuration, making it a more complex deployment than simple port security.

Implementing Software-Defined Networking (SDN) and security groups represents a major network architectural overhaul, which is far more complex and disruptive for an existing access layer than port security.
