Which IEEE mechanism is responsible for the authentication of devices when they attempt to connect to a local network?
Click on the arrows to vote for the correct answerA. B. C. D.
The correct answer is C. 802.1x.
802.1x is an IEEE standard that provides port-based network access control. It is used to authenticate devices when they attempt to connect to a local network.
When a device attempts to connect to a network port, 802.1x sends an authentication request to the device. The device then sends its credentials (such as a username and password) to the authentication server, which verifies the credentials and sends a response to the network switch.
If the authentication is successful, the switch allows the device to access the network. If the authentication fails, the switch denies access to the device.
802.11 is a standard for wireless local area networks (WLANs). It defines the specifications for wireless communication between devices.
802.3x is a standard for Ethernet flow control. It defines a mechanism for devices to signal to each other when they are able to send data.
802.2x is not a valid IEEE standard.
Therefore, the correct answer is C. 802.1x.
