What is a floating static route commonly referred to in networking?

1. Default static route

2. Dynamic route

3. Backup static route

4. Permanent route

The correct answer is: Backup static route

A floating static route is commonly referred to as a backup static route. This type of route is configured with a higher administrative distance than the primary route, which typically means it will only be used if the primary route becomes unavailable. The purpose of a floating static route is to provide redundancy in routing, ensuring network availability and reliability. When a primary route fails, the floating static route kicks in to maintain connectivity. This concept is crucial in network design, as it enhances fault tolerance. It is optimal for scenarios where you want to ensure that there is a fallback option available without constantly relying on the secondary path under normal operating conditions. The other options do not accurately describe a floating static route: a default static route serves as a catch-all for traffic destined for an unknown network, dynamic routes are learned and maintained by routing protocols rather than configured manually, and a permanent route usually refers to routes that remain in the routing table unless explicitly removed.
