Explanation
802.1X is a port-based Network Access Control (NAC) standard that authenticates devices (and users) before granting network access - only authorized devices with valid credentials pass through; unauthorized ones are blocked at the switch port level. A (ACL) filters traffic based on IP/MAC addresses but doesn't authenticate devices before they connect. C (QoS) prioritizes network traffic for performance, not security. D (DHCP Snooping) prevents rogue DHCP servers and IP spoofing but doesn't restrict which devices can connect to a port.
Memory tip: Think "802.1X = eXclusive entry" - like a bouncer checking IDs at the door before anyone gets in.
