1. 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 scales well with expanding networks
Static routing requires very little knowledge of the network for correct implementation
Static routing uses fewer router resources than dynamic routing*
Static routing is relatively easy to configure for large networks

2. Refer to the exhibit. What routing solution will allow both PC A and PC B to access the Internet with the minimum amount of router CPU and network bandwidth utilization?

Configure a static route from R1 to Edge and a dynamic route from Edge to R1
Configure a static default route from R1 to Edge, a default route from Edge to the Internet, and a static route from Edge to R1*
Configure a dynamic route from R1 to Edge and a static route from Edge to R1
Configure a dynamic routing protocol between R1 and Edge and advertise all routes

3. What is the correct syntax of a floating static route?

ip route 209.165.200.228 255.255.255.248 serial 0/0/0
ip route 209.165.200.228 255.255.255.248 10.0.0.1 120*
ip route 0.0.0.0 0.0.0.0 serial 0/0/0
ip route 172.16.0.0 255.248.0.0 10.0.0.1

4. What is a characteristic of a static route that matches all packets?

It backs up a route already discovered by a dynamic routing protocol
It uses a single network address to send multiple static routes to one destination address
It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route*
It is configured with a higher administrative distance than the original dynamic routing protocol has

5. What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?

dynamic route
default route *
destination route
generic route

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

7. A company has several networks with the following IP address requirements:
IP phones – 50
PCs – 70

172.16.0.0/25
172.16.0.0/24*
172.16.0.0/23
172.16.0.0/22

8 What happens to a static route entry in a routing table when the outgoing interface associated with that route goes into the down state?

The static route is removed from the routing table*
The router polls neighbors for a replacement route
The static route remains in the table because it was defined as static
The router automatically redirects the static route to use another interface
