GUARANTEED SUCCESS
Which of the following best describes how a router operates to transmit messages to different
LAN segments? ------- ✔ CORRECT ANSWER ✓✓The router reads the LAN segment address
contained in the message and consults the appropriate routing table for the protocol, then
forwards the message to the appropriate LAN segment.
Which of the following statements about routers are true? (Select two.) ------- ✔ CORRECT
ANSWER ✓✓They examine the destination device address contained in packets to make routing
decisions.
They use logical network and device addresses to route data between networks.
How does a router use frames to route data through a network? ------- ✔ CORRECT ANSWER
✓✓The router checks the MAC address in the frame, replaces the MAC address of the source
with its own MAC address, and sends it to the proper host.
Which internal routing logic organizes routing data using a tree structure, which allows very fast
searches and requires less time to route packets? ------- ✔ CORRECT ANSWER ✓✓Cisco express
forwarding
You are designing a routing solution for your organization. You want to improve routing
efficiency by ensuring that routers save frequently used data link headers to encapsulate
packets.
,Which types of routing logic could you implement? (Select two.) ------- ✔ CORRECT ANSWER
✓✓Fast Switching
Cisco Express Forwarding
Which processes does Cisco express forwarding (CEF) use to optimize packet processing
through a router? (Select two.) ------- ✔ CORRECT ANSWER ✓✓Organizes routing data in the
forwarding information base (FIB).
Maintains adjacency tables.
Which Cisco express forwarding mechanism maintains Layer 2 information linked to a particular
entry in the routing table, reducing the need to send ARP requests before forwarding packets? --
----- ✔ CORRECT ANSWER ✓✓Adjacency tables
Match each default administrative distance with the correct route type. (Each item may be used
once, more than once, or not at all.) ------- ✔ CORRECT ANSWER ✓✓EIGRP internal routes: 90
EIGRP external routes: 170
OSPF: 110
RIP: 120
Static routes: 1
The administrative distance determines the trustworthiness of the route source. Assuming that
two separate routes are available to the same location, the router will use the following criteria
for choosing between these routes. Put the criteria in order. ------- ✔ CORRECT ANSWER ✓✓1 : If
a static route is available, it is selected.
2 : If a router has learned of two routes to a single network through different routing protocols,
it chooses the route with the lowest administrative distance.
3 : If a router has learned of two routes through the same protocol, the router will choose the
route that has the best cost as defined by the routing metric.
,Which of the following best describes a hop count? ------- ✔ CORRECT ANSWER ✓✓The number
of routers needed to get to the destination network.
If you have one router on your network and the IP address doesn't match one of the devices on
your network, where would the default static route direct packets? ------- ✔ CORRECT ANSWER
✓✓To your Internet Service Provider
You have a small network as shown. You have configured RIP on both RouterA and RouterB. The
show ip route command on RouterA shows the following information:

You want to configure a default route so that all packets for unknown networks are sent to
RouterB. Which com ------- ✔ CORRECT ANSWER ✓✓ip default-network 10.0.0.0
You are working at the console of a new router. You want to check the configuration of a
neighboring router called Sales5. You type telnet Sales5 at the router prompt and receive the
following message:
Translating "Sales5"...domain server (255.255.255.255)% Unknown command or computer
name, or unable to find computer address
, What should you do? ------- ✔ CORRECT ANSWER ✓✓Configure an address of a DNS server for
the router to contact
Last night, an administrator connected a new router to his network and enabled the RIP routing
protocol. This morning, when the administrator returned, he discovered the router wasn't
forwarding packets to networks connected to the Serial1 interface. He examines the routing
table using the command show ip route.
What could be the cause of the problem? ------- ✔ CORRECT ANSWER ✓✓The Serial1 interface is
administratively shut down.
The administrator of a corporate network is receiving complaints from internal users that they
cannot access the internet. The administrator displays the routing table of the local router using
the show ip route command.
What should the administrator do on the local router to provide internal users access to the
internet? ------- ✔ CORRECT ANSWER ✓✓Configure a default route using ip route 0.0.0.0 0.0.0.0

You have issued the following command on your router:
Router(config)#ip route 202.22.12.0 255.255.255.0 192.168.1.1
Which of the following are configured by the parameters in this command? (Select two.) -------
✔ CORRECT ANSWER ✓✓The next hop router address is 192.168.1.1.
A route to network 202.22.12.0 is added.
You are the administrator of the network shown. You want to configure the stub network
located in Tampa to forward packets to Chicago, but you do not want the overhead associated
