The primary purpose of a guest network is to ensure that visitors do not access the private network. A guest network is a separate segment of a network that is set up specifically for users to connect their devices while keeping the main network secure and isolated from unauthorized access. This segregation protects sensitive data and resources on the primary network, preventing security risks that could arise from giving guests direct access to internal resources.

In this setup, guests can access the internet or limited resources as determined by the network administrator, while the core network remains secure. This design is critical in both home and business environments, as it balances the need for connectivity with the importance of security.

The other options may seem plausible but do not encompass the primary motive for establishing a guest network. For example, while unrestricted internet access can be a feature of a guest network, it is not the central focus—it’s about limiting access to private resources. Allowing easy access for all devices is too broad and can lead to security vulnerabilities. Facilitating file sharing among guests contradicts the intent of restricting access to the private network, as it could potentially allow guests to access or share files within the secure environment. Thus, the main objective remains the protection of the primary network against unauthorized access from guests.
