What is WPA2 also known as? WiFi Privileged access 802.11x 802.8i

802.11x WPA2-Enterprise with 802.1X Authentication 802.1X is an IEEE standard framework for encrypting and authenticating a user who is trying to associate to a wired or wireless network. WPA-Enterprise uses TKIP with RC4 encryption, while WPA2-Enterprise adds AES encryption. 802.1X can be transparent to wireless users. 802.1X utilizes the Extensible Authentication Protocol (EAP) to establish a secure tunnel between participants involved in an authentication exchange.

What is needed to use WPA/WPA2 Enterprise on a Wi-Fi network? A RADIUS server TACAC+ A hardware token It is not possible

A RADIUS server Remote Authentication Dial-In User Service (RADIUS) is a client-server networking protocol that runs in the application layer. The RADIUS protocol uses a RADIUS Server and RADIUS Clients. A RADIUS Client (or Network Access Server) is a networking device (like a VPN concentrator, router, switch) that is used to authenticate users. A RADIUS Server is a background process that runs on a UNIX or Windows server. It lets you maintain user profiles in a central database. Hence, if you have a RADIUS Server, you have control over who can connect with your network. When a user tries to connect to a RADIUS Client, the Client sends requests to the RADIUS Server. The user can connect to the RADIUS Client only if the RADIUS Server authenticates and authorizes the user

Why should you avoid using WEP on the Wi-Fi network? It is an old Cisco-only standard The initialization vectors aren't random enough It is still okay to use but there are better solutions User authentication is too complicated

The initialization vectors aren't random enough (WEP) Wired Equivalent Privacy. Wireless encryption standard. The main problem with WEP is that it only uses one static key when sending data from your computer. This wasn't a problem when WEP first arrived; however, as time went on, hackers cracked the code behind the keys. As such, once a hacker knows the key for your Wi-Fi communication, they can break the encryption and read the data you're sending.
