Why would a floating static route be configured with an administrative distance that is higher than the administrative distance of a dynamic routing protocol that is running on the same router?

to be the priority route in the routing table
to be used as a backup route*
to act as a gateway of last resort
to load-balance the traffic

12 
Which two statements describe classful IP addresses? (Choose two.)

All subnets in a network are the same size.*
Only Class A addresses can be represented by high-order bits 100.
Three of the five classes of addresses are reserved for multicasts and experimental use.
The number of bits used to identify the hosts is fixed by the class of the network.*
Up to 24 bits can make up the host portion of a Class C address.
It is possible to determine which class an address belongs to by reading the first bit.

13

What happens to a static route entry in a routing table when the outgoing interface is not available?

The router polls neighbors for a replacement route.
The router redirects the static route to compensate for the loss of the next hop device.
The route is removed from the table.*
The route remains in the table because it was defined as static.
