13.
Which two statements describe classful IP addresses? (Choose two.)
The number of bits used to identify the hosts is fixed by the class of the network.
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.
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.

The network administrator configures the router with the ip route 172.16.1.0 255.255.255.0 172.16.2.2 command. How will this route appear in the routing table?
S 172.16.1.0 is directly connected, Serial0/0
S 172.16.1.0 [1/0] via 172.16.2.2
C 172.16.1.0 [1/0] via 172.16.2.2
C 172.16.1.0 is directly connected, Serial0/0

16.
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.

What are two advantages of static routing over dynamic routing? (Choose two.)
Static routing is more secure because it does not advertise over the network.
Static routing uses fewer router resources than dynamic routing.

Static routing is relatively easy to configure for large networks.
Static routing requires very little knowledge of the network for correct implementation.
Static routing scales well with expanding networks.
