In which scenario would an “Interface Group” be beneficial?

An "Interface Group" is particularly beneficial when multiple interfaces need to be managed collectively. This setup allows administrators to group several network interfaces together so that they can be configured, monitored, and managed as a single entity. By doing so, it simplifies management tasks and reduces the complexity that can arise from handling each interface individually.

For example, if you have multiple Ethernet ports on a Firebox that share similar security policies or traffic handling preferences, creating an Interface Group allows you to apply the same configurations simultaneously across all grouped interfaces. This not only streamlines administrative efforts but also ensures consistency in network policies.

Choices related to monitoring guest user activity, creating unique firewall rules for every device, or establishing VPN connections primarily address specific use cases rather than the collective management capabilities that an Interface Group provides, thus highlighting its unique advantage in network management.
