Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 97

An administrator is configuring a switch port for use with 802.1X.
What must be done so that the port will allow voice and multiple data endpoints?

Answer options

• A. Connect a hub to the switch port to allow multiple devices access after authentication.
• B. Configure the port with the authentication host-mode multi-auth command.
• C. Connect the data devices to the port, then attach the phone behind them.
• D. Use the command authentication host-mode multi-domain on the port.

Correct answer: B

Explanation

The correct answer is B because the 'authentication host-mode multi-auth' command allows for multiple devices to authenticate on a single port, which is essential for supporting both voice and data endpoints. Option A is incorrect as a hub is not necessary and does not provide the required authentication capabilities. Option C does not allow for proper authentication of multiple devices, and option D is incorrect as 'multi-domain' is not designed for the same purpose as 'multi-auth'.
