The correct answer is C. They have a higher administrative distance than the default static route administrative distance D. They are used as back-up routes when the primary route goes down. Floating static routes are backup routes configured with a higher administrative distance than the primary route, ensuring they are only used if the primary route becomes unavailable.

Why each option

Floating static routes are backup routes configured with a higher administrative distance than the primary route, ensuring they are only used if the primary route becomes unavailable.

AThey are routes to the exact /32 destination address

Floating static routes can be to any destination address, not necessarily limited to /32 (host) routes.

BThey are used when a route to the destination network is missing

They are not used when a route is missing, but rather as a backup to an existing, preferred route.

CThey have a higher administrative distance than the default static route administrative distanceCorrect

Floating static routes are configured with an administrative distance higher than the primary route (e.g., a directly connected route, OSPF, or a standard static route), making them less preferred.

DThey are used as back-up routes when the primary route goes downCorrect

Their higher administrative distance means they are only installed in the routing table and used for traffic forwarding if the primary, more preferred route becomes inactive, thus serving as a backup.

EThey are dynamic routes that are learned from a server

Floating static routes are manually configured static routes, not dynamically learned from a server or routing protocol.
