What does a lower administrative distance indicate?

1. The route may be less reliable

2. The route may be less preferred

3. The route is more trustworthy

4. The route is completely inactive

The correct answer is: The route is more trustworthy

A lower administrative distance indicates that the route is considered more trustworthy. Administrative distance is a metric used by routers to determine the reliability of different routing protocols. Each routing protocol is assigned a default administrative distance value, which reflects its perceived reliability or trustworthiness. When a router receives information about multiple routes to a destination, it will compare the administrative distances of those routes. The route with the lowest administrative distance is preferred, meaning the router will choose to use that route to reach the destination. In this context, because a lower administrative distance signifies higher trust and reliability in the routing protocol providing the route, this option accurately conveys the concept of administrative distance in routing.
