We have seen a variety of cities providing free wifi for their inhabitants. However, when providing the full Internet without authentication, you run the risk of criminal activities to happen using that free Wifi. When you run authentication, it makes access cumbersome. Thus, the idea is to provide free low-capacity Internet without authentication, which would allow you to only consume information (no file download, no gaming, no streaming/video). With the knowledge of risk assessment, the candidate should be able to evaluate the security of such an open access.
