Community Insight

The question tests knowledge of access control methods, specifically that captive portals are designed for guest and temporary authentication rather than for permanent enterprise authentication or encryption standards.

Captive portals are the standard solution for managing temporary guest access to a network, as they redirect users to an authentication web page. Community consensus strongly supports option A (Captive portal) for this scenario.

Choosing Enterprise authentication (B) is the most common mistake because it involves authentication, but it is designed for permanent employees and requires complex directory integration, not temporary access.

The correct answer is A: Captive portal. Captive portals are specifically designed for temporary access management. The other options are less suitable because: Enterprise authentication (B): This is more suited for permanent employees and requires complex setup Ad hoc network (C): This refers to a temporary network structure, not an authentication method WPA3 (D): This is an encryption standard for securing wireless networks, not specifically for managing temporary access

A. captive portal A Wi-Fi network implementation used in some public facilities that directs attempts to connect to the network to an internal Web page for that facility; generally used to force terms of service on users.

A captive portal is a web page that users see before accessing a public network. Users typically need to provide some form of authentication, such as logging in with temporary credentials, before they can access the network. This is particularly useful for temporary access as it can be used to enforce network access policies and gather user information.

Captive portal is what we all do. It's easy, self-service, and you can log MAC addresses and user email addresses without any work on your part.

Expert Analysis

Why the Answer Is Correct

Captive portals are network access control mechanisms that intercept users' connections and force them to authenticate or accept terms before granting access. This makes them ideal for temporary guest access, as the administrator can issue time-limited credentials or simply collect user information. A community comment correctly notes that captive portals are used in public facilities to force terms of service on users, which matches the temporary access requirement.

Why the Other Options Are Wrong

Enterprise authentication (B) is designed for ongoing, managed access for organizational users, typically via 802.1X or RADIUS, and is too complex for temporary guests. Ad hoc network (C) is a peer-to-peer wireless topology, not an authentication method, so it does not facilitate authentication itself. WPA3 (D) is a wireless security encryption standard, not an authentication process for granting temporary access; it protects data but does not manage user onboarding.

Community Comment Notes

Comment [1] clearly explains why captive portal is correct and dismisses the other options: enterprise authentication is for employees, ad hoc is a network structure, and WPA3 is an encryption standard. Comment [3] reinforces that captive portals allow temporary credentials and policy enforcement. Even comment [2] provides the CompTIA definition, confirming the term 'captive portal' as the right choice.

Exam Strategy

When a question mentions 'temporary access' or 'guest network,' look for the option that explicitly describes a web-based portal for authentication. Remember that WPA3 and ad hoc are about encryption and topology, while enterprise authentication is for permanent users.
