Question 1
[am4show have=’p2;’]Refer to the exhibit. A TFTP server has recently been installed in the Atlanta office. The network administrator is located in the NY office and has made a console connection to the NY router. After establishing the connection they are unable to backup the configuration file and IOS of the NY router to the TFTP server. What is the cause of this problem?
A. The NY router has an incorrect subnet mask.
B. The TFTP server has an incorrect IP address.
C. The TFTP server has an incorrect subnet mask.
D. The network administrator computer has an incorrect IP address.
Answer: C[/am4show]
Question 2
[am4show have=’p2;’]Refer to the exhibit. A network administrator has configured a Catalyst 2950 switch for remote management by pasting into the console the configuration commands that are shown in the exhibit. However, a Telnet session cannot be successfully established from a remote host. What should be done to fix this problem?
| interface vlan 1 ip address 192.168.17.253 255.255.255.240 no shutdown exit ip default-gateway 192.168.17.1 line vty 0 15 password cisco login exit |
A. Change the first line to interface fastethernet 0/1.
B. Change the first line to interface vlan 0/1.
C. Change the fifth line to ip default-gateway 192.168.17.241.
D. Change the fifth line to ip route 0.0.0.0 0.0.0.0 192.168.17.1.
E. Change the sixth line to line con 0.
Answer: C[/am4show]
Question 3
[am4show have=’p2;’]Refer to the exhibit. The two connected ports on the switch are not turning orange or green. What would be the most effective steps to troubleshoot this physical layer problem? (Choose three)
A. Ensure that the Ethernet encapsulations match on the interconnected router and switch ports.
B. Ensure that cables A and B are straight-through cables.
C. Ensure cable A is plugged into a trunk port.
D. Ensure the switch has power.
E. Reboot all of the devices.
F. Reseat all cables.
Answer: B D F[/am4show]
Explanation
The ports on the switch are not up indicating it is a layer 1 (physical) problem so we should check cable type, power and how they are plugged in.
Question 4
[am4show have=’p2;’]Refer to the exhibit. A person is trying to send a file from a host on Network A of the JAX Company to a server on Network Z of the XYZ Company. The file transfer fails. The host on Network A can communicate with other hosts on Network A. Which command, issued from router RTA, would be the most useful for troubleshooting this problem?
A. show flash:
B. show history
C. show version
D. show interfaces
E. show controllers serial
Answer: D[/am4show]
Question 5
[am4show have=’p2;’]Refer to the exhibit. A user cannot reach any web sites on the Internet, but others in the department are not having a problem. What is the most likely cause of the problem?
A. IP routing is not enabled.
B. The default gateway is not in the same subnet.
C. A DNS server address is not reachable by the PC.
D. A DHCP server address is not reachable by the PC.
E. NAT has not been configured on the router that connects to the Internet.
Answer: C[/am4show]
Question 6
[am4show have=’p2;’]Refer to the exhibit. A network administrator is troubleshooting a connectivity problem on the serial interfaces. The output from the show interfaces command on both routers shows that the serial interface is up, line protocol is down. Given the partial output for the show running-config in the exhibit, what is the most likely cause of this problem?
A. The serial cable is bad.
B. The MTU is incorrectly configured.
C. The Layer 2 framing is misconfigured.
D. The IP addresses are not in the same subnet.
Answer: C[/am4show]
Question 7
[am4show have=’p2;’]While troubleshooting a connectivity issue from a PC you obtain the following information:
Local PC IP address: 10.0.0.35/24
Default Gateway: 10.0.0.1
Remote Sever: 10.5.75.250/24
You then conduct the following tests from the local PC:
Ping 127.0.0.1 – Successful
Ping 10.0.0.35 – Successful
Ping 10.0.0.1 – Unsuccessful
Ping 10.5.75.250 – Unsuccessful
What is the underlying cause of this problem?
A. A remote physical layer problem exists.
B. The host NIC is not functioning.
C. TCP/IP has not been correctly installed on the host.
D. A local physical layer problem exists.
Answer: D[/am4show]
Question 8
[am4show have=’p2;’]Refer to the exhibit. A host is connected to switch port fa0/3. The host and switch have been fully configured for IP connectivity as shown. However, the indicator LED on switch port fa0/3 is not on, and the host cannot communicate with any other hosts including those connected to VLAN 2 on the same switch. Based on the given information, what is the problem?
A. switch port fa0/3 is not configured as a trunk port
B. there is a bad cable
C. the switch has been assigned an incorrect subnet mask
D. switch port fa0/3 has been blocked by STP
E. the switch and the host must be in the same subnet
Answer: B[/am4show]
Question 9
[am4show have=’p2;’]Refer to the exhibit:
Serial0/0 does not respond to a ping request from a host on the FastEthernet0/0 LAN. How can this problem be corrected?
A. Enable the Serial 0/0 interface.
B. Correct the IP address for Serial 0/0.
C. Correct the IP address for FastEthernet 0/0.
D. Change the encapsulation type on Serial 0/0.
E. Enable autoconfiguration on the Serial 0/0 interface.
Answer: A[/am4show]
Explanation
Serial0/0 is “administratively down”, that means this interface is shutting down.
Question 10
[am4show have=’p2;’]Refer to the exhibit. Why was this message received?
| Router#telnet 10.3.1.2 Trying 10.3.1.2 … Open Password required, but none set |

Question 11
[am4show have=’p2;’]Refer to the exhibit. Which two of the output fields could help you determine if a broadcast storm has occurred? (Choose two.)
A. giants
B. no buffer
C. collisions
D. ignored
E. dribble condition
Answer: B D[/am4show]
would you please sombody describe men question no2?
The answer is C because A) does not belong B) is incorrect D) Is another way to define the route out and E) is incorrect because you are not dealing with the console to telnet.
C) is correct because if you break the mask down it comes out to 192.168.17.241 – 192.168.17.254 which is decided by the .240 mask
@romina
The switch IP address and the default gateway address are actually on different subnets. IP and gateway addresses must be on the same network so the gateway address should be changed.
@Romina, it’s called subnetting….
question 1 was on my icnd1 exam.
Anyone,
I plan on taking exam next week. What other sims/labs did you get besides the OSPF 6 router?
Thanks in Advance!
question 2/
mask 240 = /28 = 16 – 2 hosts or 14 hosts
How is it possible?!?! the IP address 192.168.17.253 just has one more ip, or 192.168.17.254.
This question is totally weird to me!
Probably the best way to understand a question like this is to recreate it in your own CCNA lab. It is a combination of understanding subnetting and when you can actually try it in your own lab it makes all the difference in the world instead of trying to memorize this. I got a CCNA lab here http://www.certificationkits.com/ccna-certification-kits/ with three 1841 routers and a 3550 switch and two 2950s(they also include a 100 page subnet workbook that has about 150 practice questions). You can easily recreate scenarios like this and see it work. I got a 978 this morning on my exam between my lab and here. Best of luck, on to the next Cisco exam!
@max,
192.168.17.253/28 is just host-IP,but not network-subnet IP.So,32-28=4,2^4=16(box size=increment). 192.168.17.240 is the network-subnet IP (or lets say subnet ID).
192.168.17.255 is the broadcast IP for this subnet,and 192.168.17.241-192.168.17.254 is the range for valid host IPs.If we change IP of gateway to the IP that falls to this range,then we can access to the switch remotely.So,192.168.17.241 falls to this range.
Q1 – According to the router, the network is 172.16.1.96 /29, but the server thinks it’s 172.16.1.96 /28. The highest usable address is 172.16.1.102, which includes the server address. So, the server should be able to communicate with NY. It will only have problems with addresses 172.16.1.103 – 172.16.1.111. So, that entire question is wrong.
@JamesK, I think what they are going for here is recognizing that that the CIDR and server subnet don’t match. It’s all about the process of troubleshooting.
Konan, you are right! When I take a look on this question I was tired hehe. I was studying it for a long time. Well, sorry and thanks for your help
Q1 – @JamesK, totally agree. Would still pick answer C, but the question is stupid as the TFTP communication from NY router will work with the TFTP server.
Passed my 100-101 exam today and question 1,2 were there.. all the best

Guys you should get free dumps and many other helping materials from [ http://adf.ly/o7ba3 ]
Its a direct and safe download and the download speed is ultra high.
Also the dumps is super easy to download.
Enjoy.
had both of these which I answered as shown here. However must have been another troubleshooting question in there as I got something in there wrong.
Please add more troubleshooting questions if you remember more than these two questions.
I’m planning on taking the test by 8/9. Please contribute if you took the 100-101.
Yesterday pass the exam, most of the questions are from 9tut website, good luck for all.
Took exam yesterday, both these questions were on it.
Question 2
C is correct because different network
why wouldn’t Q2 be 192.168.17.240 for the IP default gateway? I understand .241 – .254 are valid hosts IP’s. So we would use the first available host IP .241 for the IP default gateway
Questions 1-2 were in exam on 20/11/2014, more than 45 questions were from 9tut !
Hi , passed the ICND today with 947/1000. If you have some questions, just ask -> boogey_leo@yahoo.fr
The Q1 & Q2 were in exam today
sandy pls do we need command for the troubleshooting questions or its just multichoice answers all through
Hey I’m planning on taking CCNA in a couple of weeks. I have been extensively studying from 9tut. Can anyone please tell me if its just enough to go through 9tut? Will I pass if I do that? My confidence level is very low and I just want to pass this very badly.
For Qs2:
Subnet mast 255.255.255.240. convert 240 to binary and we get lowest bit as 16. Therefore increment is 16.
start address: 192.168.17.0 – 192.168.17.15
…………………192.168.17.16 (keep adding 16 till u reach address within 192.168.17.253)
…………………192.168.17.240 – 192.168.17.255 ( – thats the network range) – therefore 192.168.17.241 becomes valid router IP
…………………192.168.18.0
q1 in icnd1 exam
Took exam today. both Q1 and Q2 were in the exam exactly as they are
Q1 in exam
@ Anonymous what else did you study beside the material that is here on 9tut.net. I wanna book for the test this week but i am not sure if I am 100% ready for the exam… please help with info in regards with study material. thanks.
This question came in the exam today
29/4/2015
Both of these questions were in my exam yesterday nearly word for word.
why default-gateway 192.168.17.241 for 2nd question,why not default-gateway 192.168.17.1 ??
Passed both question was on
Admin is not the password
Hi Everyone. any advise how i can guarantee pass for icnd1. The exam costs a lot of money and i dont want to fail. God Bless.
guys i got free dumps with nuggets from this following link
wurl. cc/dumps
why does question 1 is C, i think the subnet mask is all right
question 1 can’t be C, the subnet mask needs to match the mask for the LAN int on the router (/29 or .248)
meant to say “has to be C.”
@all: We had to move all the questions and answers out of 9tut. We can only keep the explanation. You can download the questions and answers at: https://mega.co.nz/#!oIdESYbD!yyu33vygrfKPy4rcmcbV6qW2fxINNoTokuDM3CjA_og
Re: question 1, the subnet mask can be different as long as the ip addresses are both in the same network. Both the TFTP server and the router LAN router interface are both in the 172.16.1.96 network. Try it on live gear or packet tracer and it works just fine.
why can i not see the questions??
@tyler: You can download the questions in a PDF file at: https://www.9tut.net/icnd1-2-questions-and-answers
Q1, I think the TFTP server address is meant to be 172.16.1.103 or higher, to .110
172.16.1.97/29->172.16.1.97-172.16.1.102 are valid IP addresses
172.16.1.101/28->172.16.1.97-172.16.1.110 are valid IP addresses
Ok it is a case of overlapping subnets but the TFTP address of 172.16.1.101 should work ok, as the address is covered by the smaller subnet of 172.16.1.97/29.
Someone correct me if this is wrong but this is how I remember the overlapping subnets explanation in my CCNA book.
Curious.. I believed the answer is correct TFTP server has an incorrect subnet mask because is connected to the switch I don’t think vlsm would apply here.. Either way I checked all Ip addresses and all them are correct.
Curious so I decided to setup a lab with this configuration and I got good connectivity with TFTP Server with subnet mask 255.255.255.240.. The problem that I see with this question is that a def. gateway is no showing on TFTP server and for this to work I have to set up a def. gateway on TFTP Server… maybe that would answer your question….. Cisco bein difficult as always.
Hi,
Where can I have access to Sims/labs of ICND1 so test like in the real exam?
Thanks

Q7
if the host can ping his own IP
(Ping 127.0.0.1 – Successful
Ping 10.0.0.35 – Successful)
that means the local physical layer is fine.
the host is not able to ping the other computer/router .
I believed the answer is
A. A remote physical layer problem exists.
why no body question the answer?
@Anonymous: In Q7, Ping to the Default Gateway is unsuccessful. So, there should be a problem within local physical layer.(According to my understanding)
