CCNA Exploration2: Routing Protocols –
Chapter 2 Exam
01. The output of the Router# show interfaces serial 0/1 command displays the
following:
Serial0/1 is up, line protocol is down.
What is the most likely cause for the line protocol being down?
Serial0/1 is shutdown.
There is no cable connecting the routers.
The remote router is using serial 0/0.
No clock rate has been set.
02. Which address can be used to summarize networks 172.16.0.0/24 thru
172.16.7.0/24?
172.16.0.0/21
172.16.1.0/22
172.16.0.0 255.255.255.248
172.16.0.0 255.255.252.0
03.
Refer to the exhibit.
How will packets destined to the 172.16.0.0 network be forwarded?
Router1 will perform recursive lookup and packet will exit S0/0.
Router1 will perform recursive lookup and packet will exit S0/1.
There is no matching interface associated with network 172.16.0.0 so packets will
be dropped.
There is no matching interface associated with network 172.16.0.0 so packets will
take gateway of last resort and exit out S0/2.
04. A static route that points to the next hop IP will have what administrative
distance and metric in the routing table?
administrative distance of 0 and metric of 0
administrative distance of 0 and metric of 1
administrative distance of 1 and metric of 0
administrative distance of 1 and metric of 1
05. Hosts on two separate subnets cannot communicate. The network administrator
suspects a missing route in one of the routing tables. Which three commands can be
used to help troubleshoot Layer 3 connectivity issues? (Choose three.)
ping
show arp
traceroute
show ip route
show controllers
show cdp neighbor
06.
Refer to the
exhibit. Which static route should be configured on Router1 so that host A will be
able to reach host B on the 172.16.0.0 network?
ip route 192.168.0.0 172.16.0.0 255.255.0.0
ip route 172.16.0.0 255.255.0.0 192.168.0.1
