be used to filter network information.
CCNA Questions
Which PPP authentication methods will you use when configuring PPP on an interface of a Cisco router?
(Select two options.)
A. SSL
B. SLIP
C. PAP
D. LAPBc
E. CHAP
F. VNP
Answer :
Answer: C E
Explanation:
Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP)
authenticate the endpoints on either end of a point-to-point serial link. Chap is the preferred method today
because the identifying codes flowing over the link are created using a MD5 one-way hash, which is more
secure that the clear-text passwords sent by PAP.

Which of the following routes will be used to forward data in a situation where a routing table contains
static, RIP, and IGRP routes destined to the same network with each set to its default administrative
distance?
A. The RIP route
B. The static route
C. The IGRP route
D. All three will load balance.
Answer :
Answer: B
Explanation:
To decide which route to use, IOS uses a concept called Administrative Distance. Administrative distance is a
number that denotes how believable an entire routing protocol is on a single router. The lower the number, the
better, or more believable the routing protocol.
Route Type Administrative Distance
• Static 1
• IGRP 100
• RIP 120

Which of the following factors determines the OSPF router ID when configuring a router with both
physical and logical interfaces?
A. The lowest network number of any interface.
B. The highest network number of any interface.
C. The highest IP address of any logical interface.
D. The middle IP address of any logical interface.
E. The lowest IP address of any physical interface.
F. The highest IP address of any physical interface.
G. The lowest IP address of any logical interface.
Answer :
Answer: F
Explanation:
The OSPF topology database includes information about routers and the subnets, or links, to which they are
attached. To identify the routers in the neighbor table’s topology database, OSPF uses a router ID (RID) for
each router. A router’s OSPF RID is that router’s highest IP address on a physical interface when OSPF starts
running.
Note: The OSPF router ID is a 32-bit IP address selected at the beginning of the OSPF process. The highest IP
address configured on the router is the router ID. If a loopback address is configured, then it is the router ID. In
case of multiple loopback addresses, the highest loopback address is the router ID. Once the router ID is elected
it doesn't change unless the IP address is removed or OSPF restarts.

Question : CCNA
You would like to deny Network 1 (shown in the following figure) from accessing the Internet. Where would be the most efficient location to apply the access list ?
access-list 75 deny 172.16.60.0 0.0.0.255
access-list 75 permit any
A. On the Homer router, Fa0/0 inbound
B. On the Homer router, Fa0/0 outbound
C. On the Homer router, S0/0 inbound
D. On the Homer router, S0/0 outbound
E. On the Marge router, S0/1 inbound
F. On the Marge router, S0/1 outbound
G. On the Marge router, S1/0 inbound
H. On the Marge router, S1/0 outbound
Answer :
F. When applying standard access lists, it's always best to apply them closest to the destination. Because they can only permit or deny based on the source address, placing them too close to the source might allow or deny too much access. For example, if the access list were placed on the Fa0/0 port of the Homer router, Network 1 would not be able to access any resources on the network. All other answers are incorrect because they are not the closest to the Internet destination

Questions : CCNA Exam Preprations
You have an internal web server that must be accessed from the corporate Internet connection. This internal web server has the IP address 172.16.55.10. The router accesses the Internet through the FastEthernet0/1 interface. What NAT syntax is necessary to forward HTTP requests to the internal web server?
A. ip nat outside destination tcp 80 fastEthernet0/1 172.16.55.10 80
B. ip nat inside source static tcp 172.16.55.10 80 interface fastEthernet 0/1 80
C. ip nat outside source tcp 80 172.16.55.10 80 interface fastEthernet0/1 80
D. ip nat inside destination static tcp 172.16.55.10 80 interface fastEthernet 0/1 80
B. The ip nat syntax can be quite cryptic because the Cisco router gives you plenty of flexibility with the form and directions of NAT translation. In this case, we are looking to create a Static NAT translation to allow TCP port 80 (HTTP) to pass through the Cisco router to the internal web server. There are two ways to accomplish this; we can create a Static NAT translation from the inside perspective or from the outside perspective. In this question, the only correct answer is the translation performed from the inside: ip nat inside source static tcp 172.16.55.10 80 interface fastEthernet 0/1 80. If we were to perform the Static NAT translation from the outside perspective, we would not be given the option to choose to translate from an interface (fastEthernet 0/1, in this case). Answers A, C, and D would result in an invalid syntax message.
Questions : CCNA Exam
Which of the following commands will enable you to specify the datagram size in a ping to 10.1.1.1?
A. Router>ping -l
B. Router#ping
C. Router#ping 10.1.1.1
D. Router>ping 10.1.1.1
B. You must use an extended ping in order to specify the datagram size when pinging an IP address. In order to do an extended ping in the Cisco IOS, you must be in Privileged EXEC mode, and the command is ping without specifying an IP address. Answer A is incorrect because that is a DOS command, not an IOS command. Answer C is incorrect because you do not specify the IP address after the ping keyword. Answer D is incorrect because you must be in Privileged EXEC mode.
Questions : CCNA Exams
Which of the following are Application layer protocols? (Choose the 3 best answers.)
A. Telnet
B. JPEG

access-list 50 permit 192.168.5.32 0.0.0.15
access-list 50 permit 192.168.5.48 0.0.0.7
access-list 50 permit 192.168.5.0 0.0.0.0
A. The packet would be denied because of the implicit deny statement.
B. The packet would be permitted because of the permit 192.168.5.32 0.0.0.15 statement.
C. The packet would be permitted because of the permit 192.168.5.48 0.0.0.7 statement.
D. The packet would be permitted because of the permit 192.168.5.0 0.0.0.0 statement.
A. The packet would be denied because of the implicit deny statement at the end of the access list. Answer B is incorrect because the first permit statement only matches the range of addresses from 192.168.5.16-31. Answer C is incorrect because the third permit statement only matches the range of addresses from 192.168.5.48-63. Answer D is incorrect because the last permit statement only matches the 192.168.5.0 network address.
