Question

You are the wireless network administrator for your organization. As the size of the organization has grown, you've decide to upgrade your wireless network to use 802.1x authentication instead of preshared keys. You've decided to use LEAP to authenticate wireless clients. To do this, you configured a Cisco RADIUS server and installed the necessary Cisco client software on each RADIUS client. Which of the following is true concerning this implementation?

1) LEAP is a secure authentication method for wireless clients
2) LEAP requires the use of preshared keys
3) LEAP is not compatible with Cisco RADIUS servers
4) LEAP does not require any additional software installation

Answer 1

LEAP is a secure wireless client authentication method that is compatible with Cisco RADIUS servers and requires additional client software installation.

You are considering using Lightweight Extensible Authentication Protocol (LEAP) to enhance security in your expanding wireless network. Among the options provided, the most accurate statement pertaining to LEAP is that it is a secure authentication method for wireless clients. However, it is important to note that LEAP, although developed by Cisco, has been found to have vulnerabilities and is considered less secure than other more modern protocols like EAP-TLS. LEAP does not require the use of preshared keys; it uses a username and password for authentication. Since LEAP is a Cisco-developed protocol, it is fully compatible with Cisco RADIUS servers. Lastly, LEAP does indeed require the installation of additional client software to be used for authentication.
