지난 몇년동안 IT산업의 지속적인 발전과 성장을 통해 Cisco 300-101 (Implementing Cisco IP Routing (ROUTE v2.0))시험은 IT인증시험중의 이정표로 되어 많은 인기를 누리고 있습니다. IT인증시험을 Pass4Test덤프로 준비해야만 하는 이유는 Pass4Test덤프는 IT업계전문가들이 Cisco 300-101 (Implementing Cisco IP Routing (ROUTE v2.0))실제시험문제를 연구하여 Cisco 300-101 (Implementing Cisco IP Routing (ROUTE v2.0))시험문제에 대비하여 예상문제를 제작했다는 점에 있습니다.
NO.1 R1 has 5 working interfaces, with EIGRP neighbors existing off each interface. R1 has routes for
subnets 10.1.1.0/ 24, 10.1.2.0/ 24, and 10.1.3.0/ 24, with EIGRP integer metrics of roughly 1 million, 2
million, and 3 million, respectively. An engineer then adds the ip summary-address eigrp 1
10.1.0.0 255.255.0.0 command to interface Fa0/ 0. Which of the following is true?
A. R1 loses and then reestablishes neighborships with all neighbors.
B. R1 no longer advertises 10.1.1.0/ 24 to neighbors connected to Fa0/ 0.
C. 1 advertises a 10.1.0.0/16 route out Fa0/ 0, with metric of around 3 million (largest metric of
component subnets).
D. R1 advertises a 10.1.0.0/16 route out Fa0/ 0, with metric of around 2 million (median metric of
component subnets).
Answer: B
Explanation:
The ip summary-address command does reset neighborships, but only on the interface under which
it is configured. After those neighborships come up, R1 will advertise the summary route, but none
of the subordinate routes inside that summary. The summary route will us a metric equal to the
metric of the lowest metric subordinate route, approximately 1,000,000 in this casE.
NO.2 A router has been configured with the commands router ospf 9, network 172.16.1.0
0.0.0.255 area 8, and network 172.16.0.0 0.0.255.255 area 9, in that order. No other OSPF-related
commands have been configured. The answers list the IP addresses that could be assigned to this
router's Fa0/ 0 interface. Which answers list an IP address/prefix length that would cause the router
to put Fa0/ 0 into area 9? (Choose two.)
A. 172.16.0.1 / 23
B. 172.16.1.1 / 26
C. 172.16.1.1 / 24
D. 172.16.0.255 / 23
E. None of the other answers is correct.
Answer: A,D
Explanation:
The wildcard mask is used for matching the prefix only, and not the prefix lengtH.
As such, 172.16.1.0 0.0.0.255 matches all addresses that begin with 172.16.1, and 172.16.0.0
0.0.255.255 matches all addresses that begin 172.16.
Also, OSPF reviews the network command with the most specific wildcard masks (wildcard masks
with the most binary 0's) first, so an interface IP address beginning with 172.16.1 matches the
command that references area 8.
NO.3 When learning a new route, if a LSA received is not found in the topological database, what
will an internal OSPF router do?
A. The sequence numbers are checked, and if the LSA is valid it is entered into the topology
database.
B. The LSA is placed in the topological database and an acknowledgement is sent to the transmitting
router.
C. The LSA is dropped and a message is sent to the transmitting router.
D. The LSA is flooded immediately out of all the OSPF interfaces, except the interface from which
the LSA was received.
Answer: D
NO.4 By default, which statement is correct regarding the redistribution of routes from other
routing protocols into OSPF?
A. They will appear in the OSPF routing table as type E1 routes.
B. They will appear in the OSPF routing table as type E2 routes.
C. Summarized routes are not accepted.
D. All imported routes will be automatically summarized when possible.
E. Only routes with lower administrative distances will be imported.
Answer: B
Explanation:
Explanation Type E1 external routes calculate the cost by adding the external cost to the internal
cost of each link that the packet crosses while the external cost of E2 packet routes is always the
external cost only. E2 is useful if you do not want internal routing to determine the path. E1 is useful
when internal routing should be included in path selection. E2 is the default external metric when
redistributing routes from other routing protocols into OSPF.
NO.5 A stub area is typically created using what kind of topology?
A. Broadcast
B. Point-to-point
C. Hub and spoke
D. Full Mesh
Answer: C
Explanation:
A stub area is typically created when you have a hub-and-spoke topology, with the spoke being the
stub area, such as a branch ofce. In this case, the branch ofce does not need to know about every
network at the headquarters site; instead, it can use a default route to get there.
NO.6 Refer to the exhibit. Which command would verify if PBR reacts to packets sourced from
172.16.0.0/16?
Select the best response.
A. show ip route
B. show policy-map
C. show access-lists
D. show route-map
Answer: D
NO.7 A ABC Company network administrator is troubleshooting an EIGRP configuration across a
discontiguous network. What must the administrator do to ensure all of the ABC Company routers
have the correct routing information?
A. The administrator must enable classless routing with the command "ip classless"
B. The administrator must disable automatic summarization with the command "no auto-summary"
C. The administrator must specify a default network with the command "ip default-network"
D. Nothing, EIGRP supports discontiguous networks by default.
E. The administrator must enable manual summarization with the command "ip summary-address"
F. None of the other alternatives apply
Answer: B
NO.8 Which command should you use to verify what networks are being routed by a given OSPF
process?
A. show ip ospf
B. show ip route
C. show ip protocol
D. show ip ospf database
E. None of the other alternatives apply
Answer: C
