You have heard the term floating static route a lot as you have been studying HA for the WAN. What does this static route technology rely on for proper operation?

Question

Group of answer choices

IPv6

Anycast

Multicast

AD

Answer 1

The correct answer is AD (Administrative Distance).

Floating static routes rely on Administrative Distance to function properly. By assigning a higher administrative distance to the floating static route than the primary dynamic routing protocol, the router knows to use the dynamic route as long as it is available. However, if the primary route fails, the router will then "float" to the static route, since it has a lower administrative distance. This mechanism makes it effective for failover scenarios in high availability configurations.
