Chapter 2 Review Questions for Networking

Refer to the exhibit. The small company shown uses static routing. Users on the R2 LAN have reported a problem with connectivity. What is the issue?

R1 needs a static route to the R2 LAN.

Refer to the exhibit. Which default static route command would allow R1 to potentially reach all unknown networks on the Internet?

R1(config)# ipv6 route ::/0 G0/1 fe80::2

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

Which three IOS troubleshooting commands can help to isolate problems with a static route? (Choose three.)

ping show ip route show ip interface brief

Refer to the exhibit. The routing table for R2 is as follows: Gateway of last resort is not set 10.0.0.0/30 is subnetted, 2 subnets C 10.0.0.0 is directly connected, Serial0/0/0 C 10.0.0.4 is directly connected, Serial0/0/1 192.168.10.0/26 is subnetted, 3 subnets S 192.168.10.0 is directly connected, Serial0/0/0 C 192.168.10.64 is directly connected, FastEthernet0/0 S 192.168.10.128 [1/0] via 10.0.0.6 What will router R2 do with a packet destined for 192.168.10.129?

send the packet out interface Serial0/0/1

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

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

Refer to the exhibit. 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*

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

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. 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? (Choose two.)

A(config)# ip route 10.0.0.0 255.0.0.0 192.168.1.2 A(config)# no ip route 10.0.0.0 255.0.0.0 172.16.40.2

Refer to the graphic. 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

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

refer to the exhibit above. 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

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

Refer to the exhibit. The network engineer for the company that is shown wants to use the primary ISP connection for all external connectivity. The backup ISP connection is used only if the primary ISP connection fails. Which set of commands would accomplish this goal?

show ip interface brief

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
