CCNA S2 Chapter 2
An administrator issues the ipv6 route 2001:db8:acad:1::/32 gigabitethernet0/0 2001:db8:acad:6::1 100 command on a router. What administrative distance is assigned to this route?
100
Refer to the exhibit. The network administrator needs to configure a default route on the Border router. Which command would the administrator use to configure a default route that will require the least amount of router processing when forwarding packets?
Border(config)#ip route 0.0.0.0 0.0.0.0 s0/0/1
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 [1/0] via 172.16.2.2
What are two advantages of static routing over dynamic routing?
Static routing is more secure because it does not advertise over the network. Static routing uses fewer router resources than dynamic routing.
What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?
default route
Which type of static route that is configured on a router uses only the exit interface?
directly connected static route
What is the correct syntax of a floating static route?
ip route 209.165.200.228 255.255.255.248 10.0.0.1 120
Which three IOS troubleshooting commands can help to isolate problems with a static route?
ping, show ip route, show ip interface brief
What is a characteristic of a static route that matches all packets?
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.
Refer to the exhibit. What two commands will change the next-hop address for the 10.0.0.0/8 network from 172.16.40.2 to 192.168.1.2?
A(config)#no ip route 10.0.0.0 255.0.0.0 172.16.40.2, A(config)#ip route 10.0.0.0 255.0.0.0 192.168.1.2
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 default route from R1 to Edge, a default route from Edge to the Internet, and a static route from Edge to R1.
Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5. How would an administrator test this configuration?
Manually shut down the router interface used as a primary route.
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.
Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5. Which route would have to go down in order for this static route to appear in the routing table?
a static route to the 192.168.10.0/24 network
A network administrator has entered a static route to an Ethernet LAN that is connected to an adjacent router. However, the route is not shown in the routing table. Which command would the administrator use to verify that the exit interface is up?
show ip interface brief
What two pieces of information are needed in a fully specified static route to eliminate recursive lookups?
the interface ID exit interface, the IP address of the next-hop neighbor
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
