Question
A network administrator wants to implement an authentication process for temporary access to an organization's network. Which of the following technologies would facilitate this process?
- A. Captive portal Correct
- B. Enterprise authentication
- C. Ad hoc network
- D. WPA3
Explanation
A captive portal intercepts a new client's web traffic and requires it to authenticate or accept terms before granting network access, which suits temporary access such as guests and visitors. Enterprise authentication (802.1X with a RADIUS server) is designed for permanent users with managed credentials. An ad hoc network is a peer-to-peer wireless mode, not an authentication process. WPA3 secures the wireless link but does not by itself provide a temporary sign-in workflow.
