1. Refer to the exhibit. Router B receives a packet with a
destination address of 10.16.1.97. What will router B do?
use the default route
2. A network is converged and the routing tables are
complete. When a packet needs to be forwarded, what is the first criterion used
to determine the best path in the routing table?
the route with the longest address and mask match to the
destination
3. Refer to the exhibit. Which statement correctly describes
this network?
There is at least one parent and one child route
4. Refer to the exhibit. Router1 has been issued the ip
classless command. What happens to packets destined to host 172.16.3.10?
forward out interface Serial0/0/1
5. The following entry is displayed in the routing table:
R 192.168.8.0/24 [120/2] via 192.168.4.1, 00:00:26,
Serial0/0/1
What type of route is this?
a level 1 ultimate network route
6. What determines if the router implements a classless
route lookup process?
The command ip classless is enabled on the router.
7. Refer to the exhibit. How many routes in this output
qualify for use as ultimate routes?
7
8. Refer to the exhibit. What protocol was used to
distribute the routing information for the network 172.16.1.4?
RIPv2
9. Refer to the exhibit. What can be determined from this
output?
All of the routes listed are network routes.
10. Refer to the exhibit. The graphic contains partial
contents of the routing table on router E. Router E is running version 12.3 of
the IOS and is configured for default routing behavior. Router E receives a
packet to forward. Which route in the routing table will be searched first and
why?
172.16.0.0/25 because it is the first level 1 route
11. Refer to the exhibit. Router1 is running IOS version
12.2. What will the network administrator need to do so that packets for
unknown child routes of 172.16.0.0/24 will not be dropped?
do nothing, ip classless is on by default
12. Refer to the exhibit. With the ip classless command
issued, what will router R2 do with a packet destined for host 172.16.4.234?
send packet out Serial 0/0/1
13. A router has the following entries in its routing table:
S 192.168.0.0/24 [1/0] via 192.168.128.2
O 192.168.0.0/25 [110/2175] via 172.16.1.1, 00:02:15,
FastEthernet0/1
D 192.168.0.0/25 [90/22455] via 172.16.2.2, 00:12:15,
Serial0/0/0
R 192.168.0.0/26 [120/2] via 172.16.3.3, 00:00:15,
Serial0/0/1
The router receives a packet that is destined for a host
with the address 192.168.0.58. Which route would this router use to forward the
packet?
the RIP route
14. Refer to the exhibit. What parent network will
automatically be included in the routing table when the three subnets are
configured on Router1?
172.16.0.0/16
15. Refer to the exhibit. What subnet mask will Router1
apply to child routes of the 172.16.0.0/24 network?
255.255.255.0
16. Refer to the exhibit. The network administrator has
discovered that packets destined for servers on the 172.16.254.0 network are
being dropped by Router2. What command should the administrator issue to ensure
that these packets are sent out the gateway of last resort, Serial 0/0/1?
ip classless
17. Refer to the exhibit. A packet destined for host
128.107.0.5/16 is processed by the JAX router. After finding the static route
in the routing table that matches the destination network for this packet, what
does the router do next?
performs a recursive lookup to find the exit interface used
to forward the packet
18. What occurs when no ip classless is implemented on the
router?
The router will assume it has knowledge of all subnets in
the network and will not search beyond child routes for a better match.
19. A route to a destination network is learned from
multiple routing protocols. What is used by a Cisco router to select the
preferred route to the destination that will be installed in the routing table?
administrative distance
