Show Configuration Sim

April 11th, 2010 in LabSim Go to comments

This task requires the use of various show commands from the CLI of Router1 to answer 5 multiple-choice questions. This does not require any configuration.


NOTE: The show running-configuration and the show startup-configuration commands have been disabled in this simulation.
To access the multiple-choice questions, click on the numbered boxes on the right of the top panel.
There are 5 multiple-choice questions with this task. Be sure to answer all 5 questions before leaving this item.

Question 1

What is the broadcast address of the subnet of the LAN connected to Router1?
A –
B -
C -
D –
E –


Answer: A


The “show running-configuration” and “show startup-configuration” have been disabled as stated above so we should use the show ip interface command to get information about the LAN network connected to Router1.


From the output we learn that the ip address of the FastEthernet interface of Router1 is and the subnet mask is /28. Therefore:

Increment: 16 (/28=1111 1111.1111 1111.1111 1111.1111 0000)
Network address:
Broadcast address: (15 = 0 + 16 – 1)

-> The broadcast address of this subnetwork is

Question 2

What is the bandwidth on the WAN interface of Router1?
A – 16 Kbit/sec
B – 32 Kbit/sec
C – 64 Kbit/sec
D – 128 Kbit/sec
E – 512 Kbit/sec
F – 1544 Kbit/sec


Answer: E


To find out the bandwidth on the WAN (serial) interface of Router1 we need to use the show interfaces serial 0/0 command:


Therefore the bandwidth on the WAN is 512 Kbit/sec.

Question 3

What interfaces on Router1 have not had any configurations applied? (Choose two)

A – Ethernet 0
B – FastEthenet 0/0
C – FastEthernet 0/1
D – Serial 0
E – Serial 0/0
F – Serial 0/1


Answer: C F


Use the show ip interface brief to identify what interfaces Router 1 have. Notice that Router1 does not have Ethernet 0 and Serial 0 interfaces. FastEthernet 0/0 and Serial 0/0 were configured with their IP addresses therefore only FastEthernet 0/1 and Serial0/1 have not had any configurations applied.

Question 4

Including the address on the Router1 FastEthernet interface, how many hosts can have IP addresses on the LAN to which Router1 is connected?
A – 6
B – 14
C – 62
D – 128


Answer: B


The mask address of interface Fa0/0 of Router1 is /28 (as shown in question 1), which has four 0 bits (1111 1111.1111 1111.1111 1111.1111 0000). Therefore there are 24 – 2 = 14 assignable IP addresses for hosts on the LAN.

Question 5

The hosts in the LAN are not able to connect to the Internet. Which commands will correct this issue?
A – Router1(conf)# interface fa0/0
Router1(conf-if)# no shutdown
B – Routed (conf)# interface fa0/1
Router1(conf-if)# no shutdown
C – Router1(conf)# interface s0/0
Router1(conf-if)# no shutdown
D – Router1(conf)# interface s0/1
Router1(conf-if)# no shutdown
E – Router1(conf)# interface s0/0
Router1(conf-if)# ip address
F – Router1(conf)# interface s0/1
Routerl (conf-if)# ip address


Answer: C


We should check the statuses of all the interfaces on Router1 with the show ip interface brief command:


From the output, we learn that the status of Serial0/0 interface which connects to ISP router is currently “administratively down”. This status indicates this interface is shutting down so we need to turn it on.

    Same security sim in icnd1 exam with the exception of /29 subnet. With this sim use show ip interface brief and show interfaces serial0/0 commands

    Hello Everyone,

    Passed ICDN today 970/1000 – THANK YOU 9tut and community.
    Not only you guys ROCK, but also EVERY question/answer on this site is dead on target.
    In my exam today I had three SIM questions, one of which was the “Show Configuration Sim” posted here.
    The only advice I can reinstate is to watch out as the numbers, answers and requirements for each questions (specially the SIMs) DO change and the answers will not be exactly the same. Though the question is precisely the same.
    Lastly, the membership fee on this site is well worth every penny. It really helped me to pass my exam today. Going for ICDN2 next week.

    This was in exam,too. We dont have to configure anything, but use show commands. So master it.

    hi all.
    I took ICND1 23-07-2015 and passed 907/1000………….thanks 9tut. I only study this site and got 907/1000 so, if you study extra sites you will be better than me. yeh there is no any configuration only practice “show commands” and practice all the SIMs.

    Hi guys im doing my ICND1 exam 2morrrow, and i have gone through the icnd1 questions over and I plan to go though them again 2 or 3 times.
    I am basically getting them all right, with the odd exception of me reading the question to quickly and answering it before looking at all the answers.
    If I can answer all these questions right, will I pass the exam?
    I also noticed there isnt much IPV6 and access lists in these questions, where on the cisco website they say that these ar included in this exam. Do i only need to know the basic theory behind them? or be able to configure them too? any help when ver you can please 😉
    Thank you in advance to all who reply and to 9tut for these dumps too!!

    This SIM was on ICND1 exam today, questions were very similar, answers were different. For all SIM problems, make sure you know how to use show commands to analyze the network. Exam did not have any configuration SIMs. If you study 9tut inside-out, you’ll be good to go. Cheerio.

    this was in my exam. DONT memorize the answers because they change it up. memorize the commands to get the answers. there are only 4 commands you need. they change up the BW speed answer

    It’s now /29 not /28 anymore please change it ,thx

    Charles, they change this up every time. None of this matched my test. Memorize the commands, not the answers.
