Exam N10-008 topic 1 question 559 discussion

802.1X: IEEE 802.1X is a network access control standard that provides an authentication framework for controlling access to LANs or WLANs (Wireless Local Area Networks). It ensures that only authorized devices and users are granted access to the network. 802.1X is commonly used in Ethernet and Wi-Fi networks to enforce user-based authentication and security policies before allowing network access. The other options have different meanings: A. 802.1Q: IEEE 802.1Q is the standard for VLAN tagging in Ethernet networks. It allows multiple VLANs to be carried over a single Ethernet link. C. 802.11ax: IEEE 802.11ax, also known as Wi-Fi 6, is a wireless networking standard that improves the efficiency and performance of wireless networks, particularly in high-density environments. D. 802.3af: IEEE 802.3af is the standard for Power over Ethernet (PoE), which allows network devices to receive power over the same Ethernet cable used for data transmission. It's not directly related to network device authentication.

B. 802.1X 802.1X is a standard for network access control (NAC) that is used to require network devices to authenticate before gaining access to a LAN (Local Area Network). It provides a mechanism for authenticating and controlling the access of devices connecting to a network, ensuring that only authorized devices are allowed access.
