Question

Which technology is BEST for port-based authentication to ensure that network clients authenticate before use?

Options

A802.3
B802.15.1
C802.1x
D802.11g

Explanation

The best technology for port-based authentication to ensure network clients authenticate before use is 802.1x. 802.1x is a standard for port-based network access control that provides a mechanism for authenticating devices before granting them access to the network. This technology is commonly used to secure wired and wireless networks. It ensures that only authenticated devices are allowed to access the network (see ISC2 Study Guide, Module 3, under Network Access Control). While 802.11g is a wireless networking standard, 802.3 is an Ethernet standard, and 802.15.1 is a Bluetooth standard, none is specifically designed for port- based authentication.
