QUESTION 1:
Under the OSPF process of your router’sconfiguration, you type in “redistribute
igrp 25 metric 35 subnets” in order to redistribute your OSPF and IGRP routing
information. What affect did the “subnets” keyword have in your configuration
change?
A. It resulted in OSPF recognizing non-classful networks.
B. It had no effect since IGRP will summarize class boundaries by default. C.
It forced IGRP into supporting VLSM information.
D. It caused OSPF to accept networks with non-classful masks.
Answer: D
Explanation:
Whenever there is a major net that is subnetted, you need to use the keyword subnet to
redistribute protocols into OSPF. Without this keyword, OSPF only redistributes major
network boundaries. It is possible to run more than one OSPF process on the same router, but
running more than one process of the same protocol is rarely needed, and it consumes the
router’s memory and CPU.

Although IGRP does indeed summarize by class boundaries, OSPF does not by default. The
“subnets” keyword enables OSPF to use VLSM information from the IGRP routes.
C. IGRP does not support VLSM routing information.
QUESTION 2:
Which routing protocols do not need to have their router ID reachable by other routers
within any given network in order to maintain proper network connectivity? (Choose all that
apply)
A. EIGRP
B. OSPF
C. BGP
D. LDP
E. TDP
F. None of the above
Answer: A, B, C
Explanation:
The router ID of each router does not necessarily need to be reached by other routers in
the network for EIGRP and OSPF. BGP uses TCP as the reliable exchange of information
between routers, and BGP routers do not need to even be directly connected. Incorrect
Answers:
D, E. LDP and TDP are not routing protocols.
QUESTION 3:
Which of the following does On Demand Routing use to transport ODR information from
router to router?
A. RIP
B. BGP
C. CDP
D. UDP
E. LSP
Answer: C
Explanation:
ODR uses information from the Cisco Discovery Protocol (CDP).
Incorrect Answers:
A, B, D, E. ODR has nothing to do with RIP, BGP, UDP, or LSP.
QUESTION 4:
A router running multiple protocols learns how to reach a destination through numerous
different methods. Which of the following information will the router use first to determine
the best way to reach the given destination?
A. The length of the network mask of a route. B
The administrative distance of a route.
C. The metric of a route.
D. None of the above.
Answer: A
Explanation:
Refer to the following example:
Let’s look at three routes that have just been installed in the routing table, and see how
they look on the router.
router# show ip route
….
D 192.168.32.0/26 [90/25789217] via 10.1.1.1 R
192.168.32.0/24 [120/4] via 10.1.1.2
O 192.168.32.0/19 [110/229840] via 10.1.1.3
….
If a packet arrives on a router interface destined for 192.168.32.1, which route would the
router choose? It depends on the prefix length, or the number of bits set in the subnet mask.
Longer prefixes are always preferred over shorter ones when forwarding a packet. In this
case, a packet destined to 192.168.32.1 is directed toward 10.1.1.1, because 192.168.32.1
falls within the 192.168.32.0/26 network (192.168.32.0 to 192.168.32.63). It is chosen
based on the longest match, not the fact that it has a lower AD. It also falls within the other
two routes available, but the 192.168.32.0/26 has the longest prefix within the routing table
(26 bits verses 24 or 19 bits).
Likewise, if a packet destined for 192.168.32.100 arrives on one of the router’s interfaces, it’s
forwarded to 10.1.1.2, because 192.168.32.100 doesn’t fall within 192.168.32.0/26
(192.168.32.0 through 192.168.32.63), but it does fall within the 192.168.32.0/24 destination
(192.168.32.0 through 192.168.32.255). Again, it also falls into the range covered by
192.168.32.0/19, but 192.168.32.0/24 has a longer prefix length.
Incorrect Answers:
B, C: The administrative distance and metric is consulted only for routes with the same
network mask length.

QUESTION 5:
Which of the following are key differences between RIP version 1 and RIP version 2?
(Choose all that apply)
A. RIP version 1 supports authentication while RIP version 2 does not. B.
RIP version 2 uses multicasts while RIP version 1 does not.
C. RIP version 1 uses hop counts as the metric while RIP version 2 uses bandwidth
information.
D. RIP version 1 does not support VLSM while RIP version 2 does. E.
RIP version 1 is distance vector while RIP version 2 is not.
F. None of the above are true
Answer: B, D
Explanation:
Both Classless Routing and Multicast updates (224.0.0.9) were impossible with RIP v1 and
are available with RIP version 2.
Incorrect Answers:
A. RIPv2 supports neighbor authentication. RIPv1 does not support this. C.
Both RIP version use hop counts as the metric.
E. Both RIP versions are distance vector routing protocols.
QUESTION 6:
You are deciding which routing protocol to implement on your network. When weighing
the different options, which of the following are valid considerations?
A. Distance vector protocols have a finite limit of hop counts whereas link state protocols
place no limit on the number of hops.
B. Distance vector protocols converge faster than link state protocols.
C. RIP is a distance vector protocol. RIP v2 and OSPF are link state protocols.
D. Distance vector protocols only send updates to neighboring routers. Link state protocols
depend on flooding to update all routers in the within the same routing domain. E. None of
the above
Answer: A
Explanation:
Only A is true.
Incorrect Answers:
B. Link state protocols have the benefit of better convergence than distance vector
protocols.
C. RIPv2 is a distance vector protocol, just like RIP version 1.
D. Link state protocols do not flood updates to every router within the same domain, just
within their area.
Which of the following are Distance Vector routing protocols? (Choose all that
apply)
A. OSPF
B. BGP
C. RIP version 1
D. ISIS
E. EIGRP
F. RIP version 2
Answer: C, E, F
Explanation:
Both RIP version 1 and RIP version 2 are distance vector protocols. EIGRP
is an enhanced distance vector protocol, relying on
the Diffused Update Algorithm (DUAL) to calculate the shortest path to a
destination within a network
Incorrect Answers:
A, D. OSPF and ISIS are link state routing protocols.
B. BGP is a path vector protocol, which is similar to a distance vector protocol, but with a
key difference. A distance vector protocol chooses routes based on hop count, where BGP
chooses routes that traverse the least number of Autonomous Systems, among other things.
