Understanding Floating Static Routes: A Backup Solution for Dynamic Routing Protocols

Which type of static route is configured with a greater administrative distance to provide a backup route to a route learned from a dynamic routing protocol? A)Floating static route. B)Default static route. C)Summary static route. D)Standard static route.

The correct answer is A) Floating static route.

A floating static route is a type of static route that is configured with a higher administrative distance compared to other routes. The administrative distance is a metric used by routers to determine the trustworthiness or reliability of a particular route. When a router has multiple routes to the same destination, it will prefer the route with the lowest administrative distance.

In the case of a floating static route, it is typically configured as a backup route to a route learned from a dynamic routing protocol. The floating static route will have a higher administrative distance, ensuring that it is only used when the dynamic routing protocol fails to provide a valid route.

This technique allows network administrators to have a backup route in case the primary route learned from the dynamic routing protocol becomes unavailable or unreachable. By configuring the floating static route with a higher administrative distance, the router will only use it when all other routes fail, effectively providing a backup option.

It is worth mentioning that the other options listed in the question are not specifically used as backup routes to dynamic routing protocols.

– A default static route (B) is a static route that is used to forward all traffic that does not match any other specific route in the routing table. It is mainly used as a gateway of last resort.
– A summary static route (C) is a single static route that represents a summary of multiple subnets or networks. It is used to reduce the size of the routing table by consolidating multiple specific routes into a single summary route.
– A standard static route (D) is simply a basic static route with a fixed destination network and next-hop IP address.

Therefore, A) Floating static route is the correct answer for a static route that is configured with a higher administrative distance to provide a backup route for a route learned from a dynamic routing protocol.
