CompTIA Network+ Practice Test

Which mode allows two devices to communicate directly without an access point?

1. Infrastructure mode

2. Point-to-point mode

3. Ad hoc mode

4. Mesh mode

The correct answer is: Ad hoc mode

In networking, Ad hoc mode refers to a setup where two or more devices communicate directly with each other without the need for a central access point or router. This peer-to-peer configuration allows for quick and spontaneous connections, making it ideal for situations where establishing an additional infrastructure would be impractical or unnecessary. Ad hoc mode is commonly used in scenarios like file sharing or gaming sessions among nearby devices, allowing for flexible and straightforward connectivity. Infrastructure mode, in contrast, necessitates the presence of an access point to facilitate communication between devices, serving as a controller that manages data traffic. Point-to-point mode typically refers to a dedicated connection between two endpoints, often in a wired context, and does not specifically address wireless direct communication like Ad hoc. Mesh mode involves multiple devices interconnected to provide more resilient and redundant networking but still relies on specific configurations and access points. Thus, in the context of direct communication between two devices without intermediaries, Ad hoc mode is the appropriate choice.
