SonicWall Network Security Administrator (SNSA) Practice Test

A route-based VPN offers several advantages, one of the most significant being its scalability. In a route-based VPN, network devices communicate through established tunnels that can handle changes in the network and manage larger volumes of traffic without requiring extensive configuration. This flexibility allows for easy integration of additional sites or users as network demands grow.

By using routing protocols, route-based VPNs can dynamically adapt to network changes, improving overall efficiency. This adaptability is particularly beneficial in environments where the network topology may frequently change or expand, such as in large enterprises or cloud-based infrastructures.

The other options do not represent valid advantages of a route-based VPN. Higher cost and lower bandwidth are generally not associated with route-based implementations, which are designed to be cost-effective and efficient. Similarly, the security level of a VPN is determined more by the particular implementation, protocols in use, and configurations rather than whether it is route-based or policy-based.
