Operations

hi 9tut..thanks for your site..it’s very helpful..

i still confuse the answer of Q3..

Address to interface router should be used network address, right ? why we used ip address to assign the fa to router ?

My answer is D, since it should subnet the 224 to 240 because the host number in A is 13 hosts..

is it correct answer ? please kindly advised ..thanks..

D is the correct answer for Q3

Hi 9tut, seems that answers B,C,D,F are all correct for question 5. Why C got left out? Can you explain?

The destination IP address is also the IP address of PC2 so there is nothing to “replace” here.

hi 9tut,
This website is very good and I really got confidence on sim questions after going thru ur website.
I took the exam 3 times and failed and I lost interest. But today , I am thinking to retake after going thru ur website.
Do you have switch related questions ? Like, 9 hosts connected to one hub and hub is connected to swithc1. There is one more set of 10 hosts connected to swithc2. switch1 willl be connected to switch2.
New host is connected to switch1 and please explain me what will happen in the flooding of frames? Does switch need some config after connecting new host?
And also, I have seen DHCP drag and drop questions. I did not prepare for part1 exam atleast. do you have any questions on this?
I appreciate your help.
Thanks a lot in advance.

For the 9 hosts connected to one hub please read http://www.certprepare.com/forum/index.php?showtopic=143

I am not sure about DHCP Drag drop question, review your knowledge about this subject. Maybe you should read DHCP Group of 4 Questions http://www.9tut.com/component/content/article/41-ccnahotspotquestions/67-dhcp-group-of-four-questions

hey 9tut can u explain the difference between
no cdp run & no cdp enable as in Q-4
as i got it
no cdp run will shut down the cdp all over the router
but no cdp enable will just affect the interface

@mahmoud

You are correct. The question stated only the s0/0 should have cpd disabled, which is why the ‘no cdp enable’ command was used only on int s0/0

Bi-An

Thats backwards the subnet mask would give 13 subnets not 13 hosts, d is correct because it’s the only address given tht’s not a Subnet or broadcast.

passed the exam today.. this was one of the question – but couldnt remember the options..

PS#telnet http://www.cico.co
Translating “www.cico.co”…domain server (255.255.255.255)
% Unknown command or computer name, or unable to find computer address

9tut

Question 3 indicates RIP version 1 is being used. RIP V1 is classfull so wouldn’t subnetting not work correctly because the router is not passing on the subnet mask of 255.255.255.224?

Thank you

I had given my ICND exam 1 recently. Got 700. Will be giving the exam next week? There was a question: to identify the cable from the diagram: Ethernet Cross-over Cable, Serial Cross-over Cable, Ethernet Straight Cable, Serial Straight Cable, Rollover cable.

Does anyone have the diagrams for all these cables?

Answer to above question: Ethernet cross over cable.

A. a rollover cable
B. an Ethernet crossover cable
C. a serial crossover cable

D. an Ethernet straight-through cable
Answer: B

the ans ethernet crossover you can google it

I took ICND1 yesterday (Passed 🙂 ) and Question 5 was there. Thanks

Question 5,answer (F) confuses me.What is the forwarding FastEthernet interface ?Please help me understand.

Senzo the initial source mac will be PC1 this is then replaced by the outgoing fast ethernet interface in this case it is fa0/1 remember the logic source\destination macs change when they go through routers where as source\dest ip addresses never change

Hello All,
pleased to meet you, i have gone thru the operations questions, however I don’t have this one clear. Would someone kindly explain?
From question 1. Answer: E – The router-to-router connection is wasting address space.
How do you get this information?
Thanks all.

Hi Spainvasion,

Question 1. Answer: E – The router-to-router connection is wasting address space.

For serial to serial connection, we always try to aim for /30 subnet which the remaining 2 bits will give us 2 host address and to maximize the use of IP addresses…

The correct answer should be;

192.168.100.0 /30
255.255.255.252
1111 1111.1111 1111.1111 1111.1111 1100
increment of 4
2^4-2=2 hosts address available per subnet

192.168.100.0-192.168.100.3 (you will notice that only 192.168.100.1 and 192.168.100.2 are available for this subnet)
192.168.100.4-192.168.100.7 (you will notice that only 192.168.100.5 and 192.168.100.6 are available for this subnet)

hope it helps. 🙂

Hi skyyyyy2001,
Thanks a lot for your explanation, very kind from you. I now understand the answer.
I have been studying a lot for ccent and I think i will do my exam in about 3 weeks time.
Hopefully I will pass.
Regards.
🙂

good luck my friend, I just had mine this morning. Passed my exam at 876, some questions are tricky, remember to keep practise subnetting.

🙂

Hi skyyyyy2001,
congratulations!! I am glad you passed!!
yes i am practicing subnetting everyday.
I need helop to understand a question from one of my practice test. Maybe you you or someone else knows about this.
in the question there is basically a screenshot from a pc ipconfig all configuration.
the ips are as follows:
IP: 172.16.236.227
Subnet mask: 255.255.255.0
Default Gateway: 172.16.236.1
DHCP server: 172.16.3.2
DNS1:10.4.8.1
DNS2:10.5.2.22
Primary Wins: 10.69.2.87
Secondary Wins: 10.69.235.228

The question then is which ip address represents the first server that this computer is trying to contact
to resolve an internet website url to an up address???
I selected DNS1:10.4.8.1 and it says is wrong.

It says the right answer is: Primary Wins: 10.69.2.87
How can this be? wins is for netbios correct?
Can some help me to understand why my answer is wrong?
Thanks in advance.

Sorry a typo, i meant:
to resolve an internet website url to an ip address???
also is not the dns server the one who translates url to ip address?
I come from mcsa and not sure why i am getting the wrong answer.
Thanks in advance.

Hi Spainvasion,

I got this from MS website… me too (coming from a MCSA and MCITP-SA background) agreed it should be DNS though…

WINS and DNS are both name resolution services for TCP/IP networks. While WINS resolves names in the NetBIOS namespace, DNS resolves names in the DNS domain namespace. WINS primarily supports clients that run older versions of Windows and applications that use NetBIOS. Windows 2000, Windows XP, and Windows Server 2003 use DNS names in addition to NetBIOS names. Environments that include some computers that use NetBIOS names and other computers that use domain names must include both WINS servers and DNS servers.

Hi all
Thanks to 9tut for this great website.
I am wondering if there is any website like this for Microsoft certifications / Linux Certifications.
Please let me know.
Thanks

Further discussion about the differences between routers and wireless APs can be found in the following section.Figure 1 A Single Home RouterIn Figure 1 Home Router A implements network address translator NAT functionality for IPv4 traffic and router functionality for IPv6 traffic. From a home network addressing perspective multi-subnet configurations and intra-home routing are unwarranted.

I passed tonight with 975/1000.
Questions 1,3,4 and 5 were on the test. Almost the same ones.

Passed ICND1 today. I had about 3 or 4 of these questions on it. Thanks 9tut. I will donate in a few minutes. I appreciate the site.

Passed ICND1 today with 962…..I only had question 5 on my exam. The only difference was the IP addresses

Studied with:
Odom ICND1 Book
Todd Lamle CCNA book
Chris Bryant (thebryantadvantage.com)

I got question 3. But remember by heart subnetting. There were 5 or 6 questions about subnetting. Actually I don’t remember if they were more.

9tut plz tell me as CCNA= ICND1+ICND2, so it upto us, either we give CCNA or ICND1 & ICND2 one by one. If m i right ? plz advise me what i will do ?

@abdullah
yes, you can take the CCNA exam or ICND1 and then ICND2 or ICND2 and then ICND1. it’s your decision

Thanks xallax
can you give me latest dumps for ccna

try http://www.ciscovce.com 🙂

Know these as they are on point and great practice!

passed ICND1 = 1000/1000
PASSED ICND2 = 1000/1000

@Prev your scores were different on the other page, guess you can’t remember what they are.

PASSED YESTERDAY- Q3 WAS ON IT.

I retook it -lol

maybe you’re just lying?

When a host has an active DNS server entry and an active WNS server entry, which one does it go to first to resolve a url to an IP address?

@flukeangler
“In theory, if DNS is available, WINS is only necessary if pre-Windows 2000 clients or servers need to resolve names. In reality, especially in large enterprise environments, applications such as SMS 2003 with its use of the 1A record, MS SQL Server 2000 for use of named pipes, and Exchange Server 2000 and 2003 both require WINS for full functionality.”
http://en.wikipedia.org/wiki/Windows_Internet_Name_Service

from the above we can state that nowadays windows xp/vista/7 hosts first go DNS, then to WINS

thank you so much 9tut I love your site. You are a genius and I appreciate your help.
you are providing a genuine platform for all the people interested to learn and share their skills thanks much man. God bless you.

xallax I bought some dumps from ciscovce and am having a problem extracting the data can you assist michaelangelodean@yahoo.com Thanks

@big mikey
please check mail/yahoo messenger. thanks

In answer to bebo:

Yes, you are correct. “no cdp run” will globally disable CDP. To leave cdp running in the router (or switch for that matter), but disable it on a specific interface, use the command no cdp enable.

Remeber, CDP is enabled on Cisco routers and switches by default.

Hi I wrote my exam for ICND1 on Dec21,2011. Got failed 799 the passing score was 804.
I had a question in which I was asked the Bandwidth of the router.
Q.1
The router was showing 100000 Kbits/Sec
and the options were:
a) 128 Kbits
b) 256 kbit
c) 512 kbits
d) 1.544 kbit it was like that, what is the right answer and why, or how we can calculate it

Q2
Then there was a question about Class A subnetting.
What is true about class A subent
a) Its start in 3rd octet with 192
b) Start in 3rd octet with 128
c) Start in 3rd octet with 00
d) Start in 3rd octet with 0

Hi all..

In the Question 2.

When we receive a “Destination Unreachable” it means that we don’t have a route for the network. So, for me the right answer is
A – The routing on Router2 is not functioning properly. Not D – The gateway address of HostA is incorrect or not configured. Because in this case, we can’t check the host fully configuration…

What do you guys think?

@nathan
traceroute shows you the devices that the icmp packets go through as it goes towards the end destination.
from the exhibit we can tell that the icmp packets did not even pass the very first device – which is the default gateway.

Very hefpful questions.. Thanks to 9tut I’ve passed today. Now onto ICND2.

Got q1 and q5 on the exam.

Can anyone tell whether the command (config)#’router rip’ starts the rip process. This was a question with some like
i )it starts RIP process but no route update advertisements are being sent.
ii) It starts RIP process and route update advertisements also start.
iii ) It does not start RIP process.
Can anyone rephrase the original question and answer what is true ?

it does start rip afaik but it wont advertise any routes, so in practice rip wont do anything, you need to add the network command before rip will do anything
hope that helped that is how i understand it at least ^^

Got this question on the Transcender exam prep and on the ICND1 exam. The correct answer is ii) It does not start RIP process.

According to the explaination by Transcender, it states that by entering the command Config#Router RIP, it puts you in RIP Configuration, but RIP does not start until after you enter the Network command.

Question 1, 2, 4 included in yesterday ICND1 exam

je vais passer mon exam vendredi prochain sDv

I just passed the ICND1 with 925/1000 today 🙂
Q1,3 and 5 were there with different subnets but same idea

Passed ICND1,

Got question3 TODAY

Yay, thanks 9tut and all fellow Cisco enthusiast for your help….. Passed icnd1 today with 825, could have done better but excited to pass after failing twice.
Cbt nuggets and I attended the icnd1 and 2 courses.

why Q1 B is not true ?

@abed
B is true.

the question asks for problems with the design

thanks 9tut…passed ICND1 today. Got que 3

passed today!!!

Got Q#3 today.. failed anyways. 2nd attempt 787, what happened to scoring on average 100 points higher on 2nd attempt?

@ABED

Because area 3 has 200 users on the network with a subnet mask of /24….. /24 has 254 available hosts on its subnet ,, so area 3 ip address IS adequate for the umber is users.

The question asked for problems. so “inadequate” wouldn’t apply to area 3.

Got question 5 on the 13th.

Passed ICND1 today must say going through the sample Qs from here and the vse’s assisted much… out of the 50 qs I had only one new which was a drag and drop listing protocols on the left ( UDP , TCP , Ethernet , SNMP and SMTP I rekon) to match them with ( Network access layer , internet layer , transport layer and application layer) if the host has initiated a mail task using reliable protocols. Before I donate would like to say chrs.

donné une idée svp; pour passer mon icnd1dans quelque jour

bonjour aidez moi svp pour passer mon icnd1 guezmajo@yahoo.fr

hello help me please to pass my icnd1 guezmajo@yahoo.fr

3 and 5 in exam passed today

@9tut
Ques 2:
If host does not have gateway set :
1. The Ping process starts the next ping request.
2. The Ping process creates an ICMP Echo Request message and sends it to the lower process.
3. The source IP address is not specified. The device sets it to the port’s IP address.
4. The destination IP address is not in the same subnet and is not the broadcast address.
5. The default gateway is not set. The device drops the packet.

in your example you show:
PC>tracert 192.168.4.7
Tracing route to 192.168.4.7 over a maximum of 30 hops:
1 62 ms 62 ms 46 ms 192.168.3.254
2 * * * Request timed out ***not destination host unreachable***
I.E. your timing out because the packet was never sent. As opposed to the icmp “destination host unreachable” message that would be generated in response to a message that was received. So the default gateway would have to be set correctly in order for that to occur.

@Mike Reno: The traceroute command lists all the IP adresses of each hop it goes through. Suppose the default gateway were set correctly but it could not reach the next hop (right behind that default gateway) then you would see the IP address 192.168.3.254 listed there. But here you cannot see that IP -> host A could not reach that default gateway -> The gateway address of HostA is incorrect or not configured.

@9tut
my point is: in practice you will not see “destination host unavailable” as a result of missing or incorrect gateway. You will see timeout. I.E.

PC>tracert 11.11.11.1 ***default gateway is set to 10.10.10.1***

Tracing route to 11.11.11.1 over a maximum of 30 hops:

1 51 ms 47 ms 63 ms 10.10.10.1
2 94 ms 78 ms 78 ms 192.168.0.3
3 78 ms 125 ms 125 ms 11.11.11.1

Trace complete.

PC>tracert 11.11.11.1 ***default gateway is set to 10.10.10.10***

Tracing route to 11.11.11.1 over a maximum of 30 hops:

1 * * * Request timed out.
2 * * * Request timed out.
3 * * * Request timed out.

I appreciate you are not the creators of the questions and provide a valuable service in facilitating understanding “best answers” and I get the purpose of this exercise. Still the question is a bit of stinker. Actually I think it’s outright invalid unless someone can tell me under exactly what real “incorrect/missing gateway config” I will see the destination host unreachable message. I would really like to know from any readers if this question has actually appeared on a recent test.

@Mike Reno — You may be correct regarding “Request Timed Out” instead of “Destination Unreachable” >>> But either in the exam or in the Real World one should use the preferred logical Answer first then look for any thing else.
When you have no default gateway set on the PC it won’t show you any IP address in return in the Traceroute command.
You have been given 4 options and you have to select the best possible answer only. And most importantly what Cisco thinks is the best answer.

Question 1

Can help me explain why C is part of the answer. me i wold have replaced C with F.

Question 1

Can someone help me explain why C is part of answer in Q1. Me i would have gone for F instead of C.

Scored a 987 today. Q3 & 5 were on the exam.

Had questions 2,3,4,5. Passed 9/23/12 with a 974. This website is awesome and is a great representation of whats on the test. I had the DORA drag and drop, and also the WAN protocol DAD. The security testlet was on there. Chose banner as part of my answers and got 100% in that area. I had lots of subnetting questions, so if you are not comfortable with subnetting, practice. For studying I used this site, cisco (for the subnetting game, and also went through their review questions), and attended a CCNA course at a certified cisco learning partner. Also had the implementation drag and drop. thanks 9tut, on to ICND2. Good luck everyone.

@Rango I had the same doubt about Question 1 – Answer C.
What I understand is.. by using a mask /24 all the available IP addresses starting from 192.168.2.2 till 192.168.2.254(not using the first and last address in the range) are occupied by the Area 2(IP address space). While by using a mask /25 .. we could take out the IP address range 192.168.2.129 – 192.168.2.254 from Area2 (IP address space) and use to create a separate IP address Space and hence conserve them or rather prevent them from getting wasted.
The questions are very tricky and not clear to understand easily what is being asked. I am not sure if my explanation is correct. If anyone have any other view please explain.

Passed my ICND1 on the 13th with 950 this question was on the Test. Thanks 9tut you guys helped alot. Really cant remember which ones where on the test but i know some of them were so make sure you know these and why answers are correct dont just memories the answers and think you will pass.

Question 1

C) This is correct since using a /25 mask allows up to 126 hosts which is more than required.
F) This is incorrect – I suspect. The large number of hosts is not ideal but IP will not reach any limitations in addressing once the subnet mask is increased. This is a bit of a trick question though since you could argue that as the question is posed IP does have a limitation since not all hosts can be addressed with the given mask. Given the options though I’d choose A, C, E as suggested

To amend my previous comment. /25 allows up to 127 – 2 = 125 hosts.

@thedude
/25 allows for 126 hosts. you might have a closed network without a default gateway.

Power over ethernet and port security are characterstics of access layer

I am totally having some unfortunate luck with all of my Cisco attempts for 640-802 and then stepping down to doing the two part 640-822 and 640-166. On my last two failed attempts with the 802 exam, I failed both exams by 10 points which caused me to go hysterical. When I decided to go for the 640-822 test, I studied hard for another 3 weeks with all sorts of tools provided:
– Leadpass
– CBT Nuggets
– Testout
– Boson 7.0 Netsim
– ITU
– Cisco Press ICND1 book by Wendell Odom
– Cisco Packet Tracer
– 9tut
– ExamCollection
– VCE
– subnettingquestions.org
and I still ended up failing for with a 775/1000. I was for sure that I passed the exam when I was killing all of my practice material. I definitely do not know what is going on and this is extremely disturbing. I keep seeing others with great success stories, and I’m trying to reach that pinnacle also to relay my experiences, but damn, I’m in a hole I can’t get out of. Can anyone out there feed me some of the latest dumps for the ICND1 exam. I would definitely appreciate this as I’m trying to be a family member in the Cisco world.
I can be reached easily at cehiem@yahoo.com…

Question 1 Explained:

A /24 allows for 254 Hosts on 1 subnet, for class C. This is far too few hosts with 500 users.

C /24 allows for 254 Hosts. With only 60 users area 2 would be fine on /25 – which allows 126 hosts. Technically /26 would be enough as it allows 62 hosts. But you want to leave room to expand.

E Using a /26 is a big waste when you only have 2 devices. That allows for 62 hosts. A /30 would be adequate as it gives 2 hosts. /29 might be more optimal as it provides 6 Hosts for expansion.

As for the ‘incorrect’ answers:
B – Area 3 has 200 users and a /24 allows more than enough with 254 hosts.

D – I believe this refers to classful routing, the diagram clearly shows different subnet masks, thus there is no reason to imply a reason to not us VLSMs.

F – Networks operate that are far larger than 500 users. Without knowing the router model and spec you could never know if this is true or not. For the present technology, 500 is nothing to worry about.

I tested setting wrong gateway and got “destination host unreachable” on my PC. 🙂

@mahmoud bebo – just one thing, you can’t disable cdp globally and have it run on an interface. But you can do it the other way around.

question 1 and 5 were today in the test i did today…

I am just confirming everything Dallas mentioned, he is right for the things to study. I had the exact exam in March and scored a 700. My SIMS were at front of the exam, don’t panic when you see them. Good Luck next time for those of us who have not crossed threshold of CCENT and Congratulations to those who have. 9tut you are the best!!!!!!!!!!!!

Got Q’s 1 & 5 on my ICND 1 today

Q1 was in the test today

Question 1, A
The subnet allows 510 adresses, why should der be a problem?
Can someone explain that?

Question 1, A
The subnet allows 510 addresses, why should there be a problem?
Can someone explain that?

Found the solution. My calculation was incorrect. The subnet allows just 254 hosts!

Taking ICND1 again on Monday..missed it by about 50 points last week..best score yet…looking to pass it next time…good luck to those getting ready..

I appreciate you sharing this blog article.Thanks Again. Will read on… best proxies http://stormproxies.com

Questions 1 and 5 were on my ICND1 today

Question 3 was in my exam 2 days ago

Can I please get explanation for question 1?
