The statement that traffic is dropped if the next hop type is none accurately reflects how routing in Azure functions. In Azure networking, if a route has its next hop type set to 'none', it indicates that there is no valid next hop for that specific route. Consequently, any traffic that attempts to use this route cannot be forwarded and will be discarded. This behavior underscores the importance of correctly defining the next hop in routes to ensure that traffic flows smoothly through the network.

In contrast, the other statements do not align with how Azure routing operates or are not universally true. For example, while system routes can be created, they are not the only type of routes that exist; user-defined routes also play a significant role. Additionally, gateways are only necessary for specific types of traffic routing, such as in hybrid configurations, rather than being mandatory in all routing scenarios. Furthermore, a default route is typically created automatically for outbound traffic, but nuances can affect its application depending on the network configuration. Hence, while various aspects of routing are manageable within Azure, understanding the specific conditions surrounding next hop types is crucial for effective network design and traffic management.
