-
Name five types of network security.
- No security
- Wired Equivalent Protection (WEP)
- Wi-Fi Protected Access (WPA)
- ...............WPA-PSK (Pre-Share Key - also known as WPA Personal)
- ...............WPA-EAP (Extensible Authentication Protocol - also known as WPA Enterprise)
- WPA2
- Open with 802.1X
-
What is the most secure wireless security method?
WPA2-EAP
-
What are three way that WPA-EAP can authenticate users?
- PEAP-MS-CHAPv2 to enable users to connect to a wireless network using their domain credentials.
- Certificates stored on the user's computers
- Certificates stored on smart cards

-
What is the default authentication method Windows 7 uses when connecting to a new WPA-EAP or WPA2-EAP network?
Secure Password (EAP-MSCHAP v2)
-
Name the two types of wireless network profiles
- All-user profiles and
- Per-user profiles
Most mobile computers are used by only a single user. However, if mobile computers inyour organization are shared between multiple users, you might want to configure wirelessnetworks to use per-user profiles. With per-user profiles, one user can connect to a wirelessnetwork without other users being able to use the same wireless network connection.
