DHCP Simulator

notthing simulatin here

Click the “R1-3” on th upper right corner for simulator.

@Anonymous: Please click the “R1-3” button on the right side to access the CLIs of the routers.

Hello, When I click on R1-R3 to see configuration, I only see three blank screens. Can we get this updated plz?

@anon: You need to type your “show” commands to get the output like in the CLIs.

Please read the explanation at https://www.9tut.net/icnd1/labsim/dhcp-sim (Question 2)
but is blank where are the explanations for Q??

@STUDing hard: This link (https://www.9tut.net/icnd1/labsim/dhcp-sim) is accessible. Please try again.

Big thank you 9tut
thanks

Hi guys,

what is the answer?

Users complain that they are unable to reach internet sites. You are troubleshooting internet connectivity problem at main office. Which statement correctly identifies the problem on Router R1?

A. Interesting traffic for NAT ACL is incorrectly configured.
B. NAT configurations on the interfaces are incorrectly configured
C. NAT translation statement incorrectly configured.
D. Only static NAT translation configured for the server, missing Dynamic NAT or Dynamic NAT overloading for internal networks.

@Digong…

Is this the configuration as it was shown on the test you took because what you posted as the run con is incorrectly posted according to the 9Tut Sim, it shows the link to the ISP as ip nat inside and the other as outside which would be wrong and (B) would be the correct answer..

If what you posted is from the test then it has to be something far different like perhaps NAT translation statement incorrectly configured

-ip nat inside source list LOCAL interface Ethernet0/0 overload
-iproute 0.0.0.0 0.0.0.0 209.165.200.226

I would guess the IP address is wrong, it’s pointing to the IP of the inbound interface of the ISP… 209.165.200.266

Someone correct me if I’m wrong on this assumption.

its just blank

I had the same output – what is the answer?

@Digong – Isn’t ip route 0.0.0.0 0.0.0.0 209.165.200.226 the default route with a the next hop to the ISP interface?

E0/0 IP Addr is: interface Ethernet0/0
description ***Link to ISP***
ip address 209.165.200.225 255.255.255.224
ip nat outside
ip virtual-reassembly in

The correct answer is the letter A.

Why?

1. The NAT interfaces configuration area correct. The ip nat statement on interfaces (inside/outside) are in place, pointing to the correct direction.

2. Interfaces address are correct.

3. The GLOBAL command to create a the PAT (NAT overloaded) are correct. The (overload) is applied to outside interfaces, in this case eth0/0. The statement also is pointing to a existing access-list.

4. The access-list is WRONG!!!! This access-list is pointing a local host address. The 127.0.0.1 is assigned to local host (local loopback). So the INTERESTED traffic is not PROCEEDING trough the NAT statement.

enjoy….

@Digong If you have the other router config, please post them.

@Elitebook what do you mean pointing to the correct direction I thought the isp is suppose to have the same IP NAT configured as the others?

I still don’t know how to make the sims work, Help!!

use IE

The questions are not opening today on any sims (prem member) is this maint time ?

That is the questions on the quiz not opening, just to be clear.

Thank you

hi.Admin I bought a subscription but unable to access to DHCP Simulator.

@Anonymous: Please type your “show” commands into the single-line textboxes. If your problem still exists, please take a screenshot of your problem and send to support@9tut.net so that we can help you.

I don’t see the explanations for the quiz for this testlet, Question “Why is R3 not receiving IPP address via DHCP. Could some one explain what would be the configuration for the connection?

The line between R2 and R3 is in admin shutdown, but the testlet quiz says that is not the correct answer, please fix the quiz!

I have passed the exam so many questions from this new updated questions above .only issue I was having was that in dhcp sim question when I use sh run command for R1 and also for others R2 and R3 it was not displaying all the info in the output like dhcp pool , nat, ntp info were missing ? Anyone knows why it was like that? Or I was doing something wrong ?

And thanks to 9tut

in the command “ip dhcp pool DHCPASSIGN3”
network 192.168.20.0 255.255.255.252
Is 192.168.20.0 255.255.255.252 looks wrong? because the LAN connected to R3 is 10.100.10.0
Is that dhcp pool should be according to 10.100.10.0?

Please help. THANK YOU

@DHCP
– 1st the DHCP statement is completely missing at R3
– 2nd the Hosts on LAN 10.x.x.x are the ones requesting the DHCP address – not the ‘target’ address for DHCP pool

Where can I find practice questions for simulations?
Regards

I just sat the ICND1 exam, and this DHCP and the Security simulation were 100% the same. And I passed.

same lab on my exam today

Hi all, 9tut,

I will pass my CCENT in 15 days, (for 1st time passing cisco exam). Does anyone can tell me if for the simtest, only the ”show running-config” command is enough? I mean could it happend that we need to play command as show ip interfaces brief, or many else? Also, does the short-cut are activated? like sh run etc…

Many thank for answer
Kind regards

i passed the exam yesterday, some questions about rip,acl, informational messages, spot the difference, debug and ipv6, and drop and match the questions,
9tut cover partial
sim are two were there.
Show Configuration Simulator. and
Security Testlet Simulator.
but i think it is better to remember all of these three just in case >> DHCP Simulator here.
i passed because of 9 tut the materials i studied, thanks 9tut

I totally agree with Hi all!!!
I had Dhcp and security testlet!!! Beware!!! Study the explanations, don’t just learn by heart the answers!!!
Thank you 9tut!!!!!!!!!!!!!!!!!!!!!!!!!!! 930+/1000

The only command that i needed was “show run” in sims

no packet tracer file I can download to practice this sim?

I’m assuming these no special configuration need for this simulation, we just need to run show run command to get the answer?

Hi, has anyone taken the icnd1 in the past month or so who can verify if the sims above are still being used ? 🙂

I’m booked to take at the weekend

@GettingReady

how did you test go?

I took the test last week and missed it by 50 points however these sims are def on the test I took on March 30- Going again this April 5th

Anyone else take ICND1 recently and can confirm if any of these SIMS are still coming up? What about the questions?

@KB, hopefully you passed the 2nd time. Did the same SIMS come up the 2nd time?

Has anyone taken ICND1 recently and are these the sims? I heard an OSPF sim was on the exam? What about the questions?

@Elite Book. The show running posted is different from simlet on 9 tut, but I agree with your answer and analysis. Just wanted to add that interface Ethernet 0/2 has an access list that would block addresses in the 10.100.20.0/24 network. Then, even if the NAT had a proper access-list and had translated incoming traffic with the 10.100.20.0/24 network, the traffic would have been blocked when trying to come out of Ethernet 0/2. Am I wrong?

Same questions as others, anyone taken it recently and got these sims?

in some sims in the real exam the show running config is disabled fyi!!!!
