Which command can you enter to configure an IPv6 floating static route?
The correct answer is D. router(config)#ipv6 route FE80.0202::/32serial 0/1 201. To configure an IPv6 floating static route, you must specify an administrative distance higher than the primary route's administrative distance, which makes it a backup route.

Why each option
To configure an IPv6 floating static route, you must specify an administrative distance higher than the primary route's administrative distance, which makes it a backup route.
The command uses an administrative distance of 1, which is the default for static routes, meaning it would be a primary static route, not a floating (backup) one.
This command configures a default static route with the default administrative distance, which would be a primary route, not a floating static route.
ipv6 route static resolve default is not a valid command syntax for configuring an IPv6 static route in Cisco IOS.
The command ipv6 route FE80.0202::/32serial 0/1 201 includes an administrative distance of 201. This value is higher than the default administrative distance of 1 for static routes, causing this route to only be installed in the routing table if a primary route with a lower administrative distance becomes unavailable, thereby functioning as a floating static route.
