An engineer must configure a core router with a floating static default route to the backup router at 10.200.0.2. Which command meets the requirements?

An administrative distance of `1` is the default for a directly connected static route, making it a primary route rather than a floating backup.

The command `ip route 0.0.0.0 0.0.0.0 10.200.0.2 10` correctly configures a static default route (`0.0.0.0 0.0.0.0`) to the next-hop `10.200.0.2` with an administrative distance of `10`. This higher AD (compared to the default 1 for static routes) ensures it acts as a floating backup, only being used if a primary route with a lower AD is unavailable.

Omitting the administrative distance defaults it to `1` for a static route, causing it to be preferred over dynamic routes or other static routes with higher ADs, thus not making it a floating route.

`floating` is not a valid keyword for specifying the administrative distance in the `ip route` command; a numeric value must be used.
