1. A static route that points to the next hop IP will have
what administrative distance and metric in the routing table?
administrative distance of 1 and metric of 0
2. What address can be used to summarize networks
172.16.1.0/24, 172.16.2.0/24, 172.16.3.0/24, and 172.16.4.0/24?
172.16.0.0/21
3. The routers in the diagram use the subnet assignments
shown. What is the most efficient route summary that can be configured on
Router3 to advertise the internal networks to the cloud?
192.1.1.0/25
4. Refer to the exhibit. What is the significance of the /8
in the route to the 10.0.0.0 network?
It indicates the number of consecutive bits, from the left,
in the destination IP address of a packet that must match 10.0.0.0 to use that
route.
5. 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.
6. A network administrator enters the following command into
Router1: ip route 192.168.0.0 255.255.255.0 S0/1/0. Router1 then receives a
packet that is destined for 192.168.0.22/24. After finding the recently
configured static route in the routing table, what does Router1 do next to
process the packet?
encapsulates the packet into a frame for the WAN link and
forwards the packet out the S0/1/0 interface
7. Refer to the exhibit. Given the output in the exhibit,
how would a clock rate be determined for this link?
The rate configured on the DCE determines the clock rate.
8. Refer to the exhibit. Which set of commands will
configure static routes that will allow the WinterPark and the Altamonte
routers to deliver packets from each LAN and direct all other traffic to the
Internet?
WinterPark(config)# ip route 0.0.0.0 0.0.0.0 192.168.146.1
Altamonte(config)# ip route 10.0.234.0 255.255.255.0
192.168.146.2
Altamonte(config)# ip route 0.0.0.0 0.0.0.0 s0/1
9. 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
traceroute
show ip route
10. Refer to the exhibit. A company network engineer is
assigned to establish connectivity between the two Ethernet networks so that
hosts on the 10.1.1.0/24 subnet can contact hosts on the 10.1.2.0/24 subnet.
The engineer has been told to use only static routing for these company
routers. Which set of commands will establish connectivity between the two
Ethernet networks?
R1(config)# ip route 10.1.1.0 255.255.255.0 192.168.0.2
R2(config)# ip route 10.1.2.0 255.255.255.0 192.168.0.1
11. Which of the following are displayed by the Router# show
cdp neighbors command? (Choose three.)
platform
holdtime
local interface
12. Refer to the exhibit. What two commands are required to
provide connectivity between the 192.168.1.0 and 10.0.0.0 networks without
requiring recursive lookup? (Choose two.)
A(config)# ip route 10.0.0.0 255.0.0.0 s 0/1/0
B(config)# ip route 192.168.1.0 255.255.255.0 s 0/0/0
13. 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)# 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
14. What happens to a static route entry in a routing table
when the outgoing interface is not available?
The route is removed from the table.
15. A router has one static route to each destination
network. Which two scenarios would require an administrator to alter the static
routes that are configured on that router? (Choose two.)
The destination network no longer exists.
A topology change occurs where the existing next-hop address
or exit interface is not accessible.
16. Why is it advisable to enter a next-hop IP address when
creating a static route whose exit interface is an Ethernet network?
In a multi-access network, the router cannot determine the
next-hop MAC address for the Ethernet frame without a next-hop address.
17. 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?
No clock rate has been set.
18. 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 172.16.0.0 255.255.0.0 S0/0/0
19. What two devices are responsible for converting the data
from the WAN service provider into a form acceptable by the router? (Choose
two).
a modem
a CSU/DSU device
20. Which of the following is true regarding CDP and the
graphic shown?
By default, Router A will receive CDP advertisements from
routers B and C.
21. Which two statements describe functions or
characteristics of CDP? (Choose two.)
It starts up automatically and allows the device to detect
directly connected neighbor devices that use CDP.
It allows systems to learn about each other even if
different network layer protocols are configured.
22. Which piece of information is available from examining
the output of the command show ip interface brief?
Interface IP address
