At a local college, students are allowed to connect to the wireless network without using a password. Which mode is the access point using?
Explanation: Network mode is not an authentication mode, it refers to WLAN standards for 802.11a/b/g/n/ac/ad and the ability for access points to operate in mixed mode to support different standards, but it is not an authentication mode. Open authentication is a null authentication mode because wireless connectivity is granted to any wireless device. This authentication is used where security is not a concern. Passive mode is not an authentication mode, it refers to the open advertisement of the SSID, standards, and security settings by an access point. Shared-key authentication uses a pre-shared key between the client and the access point.
