CNNA Chapter 2

Which block of addresses would be the minimum to accommodate all of these devices if each type of device was on its own network?

172.16.0.0/24

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

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.

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Why are the pings from PC0 to Server0 not successful?

The static route to network 192.168.2.0 is misconfigured on Router1.​

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

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*

What command would be used to configure a static route on R1 so that traffic from both LANs can reach the 2001:db8:1:4::/64 remote network?

ipv6 route 2001:db8:1:4::/64 2001:db8:1:3::2

Which three IOS troubleshooting commands can help to isolate problems with a static route?

ping show ip route 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

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What IPv6 static route can be configured on router R1 to make a fully converged network?

ipv6 route 2001:db8:10:12::/64 S0/0/1

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

Which command would be used on router A to configure a static route to direct traffic from LAN A that is destined for LAN C?

A(config)# ip route 192.168.4.0 255.255.255.0 192.168.3.2

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.*

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.

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

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

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*
