CCNA – Drag and Drop 1

February 27th, 2011 Go to comments

Here you will find answers to drag and drop Questions

Question 1:

A dental firm is redesigning the network that connects its three locations. The administrator gave the networking team 192.168.164.0 to use for addressing the entire netwok. After subnetting the address, the team is ready to assign the addresses. The administrator plans to configure ip subnet-zero and use RIP v2 as the routing protocol. As a member of the networking team, you must address the network and at the same time conserver unused addresses for future growth. With those goals in mind, drag the host addresses on the left to the correct router interface. Once of the routers is partially configured. Move your mouse over a router to view its configuration. Not all of the host addresses on the left are necessary.

vlsm1


Answer:

vlsm1_solution

Explanation:

In short, we should start calculating from the biggest network (with 16 hosts) to the smallest one using the formula 2n – 2 (n is the number of bits we need to borrow).Therefore:

16 hosts < 25 – 2 (we need to borrow 5 bits -> /27)

11 hosts < 24 – 2 (borrow 4 bits -> /28)

5 hosts < 23 – 2 (borrow 3 bits -> /29)

From the available ip addresses, we see that each of them has only one suitable solution (they are 192.168.164.149/27,192.168.164.166/28 and 192.168.164.178/29)

The smallest network is the Floss S0/0 which only requires 2 hosts = 22 – 2 (need to borrow 2 bits ->/30). There are 2 suitable answers: 192.168.164.189/30 and 192.168.164.188/30 but notice that 192.168.164.188/30 is the network address so we can not use it (because 188 = 4 * 47) -> we have to choose 192.168.164.189 as the correct solution.

In fact, it is not the formal way to solve a VLSM question so I recommend you to review your CCNA book if you haven’t grasped it well yet.

Question 2:

In order to complete a basic switch configuration, drag each switch IOS command on the left to its purpose on the right

commanddragdrop


Answer:

1) enable

2) configure terminal

3) hostname

4) Interface vlan 1

5) no shutdown

6) ip address

7) ip default-gateway

Question 3:

The Missouri branch office router is connected through its s0 interface to the Alabama Headquarters router s1 interface. The Alabama router has two LANs. Missouri users obtain Internet access through the Headquarters router. The network interfaces in the topology are addressed as follows: Missouri: e0 – 192.168.35.17/28; s0 – 192.168.35.33/28; Alabama: e0 – 192.168.35.49/28; e1 – 192.168.35.65/28; s1 – 192.168.35.34/28. The accounting server has the address of 192.168.35.66/28. Match the access list conditions on the left with the goals on the right. (Not all options on the left are used.)

accesslist1


Answer:

1) deny ip 192.168.35.16 0.0.0.15 host 192.168.35.66

2) deny ip 192.168.35.55 0.0.0.0 host 192.168.35.66

3) permit ip 192.168.35.0 0.0.0.255 host 192.168.35.66

Explanation:

1) The wildcard mask of the command “deny ip 192.168.35.16 0.0.0.15 host 192.16.35.66″ is 0.0.0.15, which is equal to network mask of 255.255.255.240 = /28. So the access list will deny all traffic from network 192.168.35.16/28 from accessing host 192.16.35.66, which is the IP address of accounting server.

2) The command “deny ip 192.168.35.55 0.0.0.0 host 192.168.35.66″ will deny host 192.168.35.55, which is a user and belongs to interface e0 of Alabama router (192.168.35.49/28) from accessing accounting server.

3) Because there is an implicit “deny all” command at the end of each access list so the command “permit ip 192.168.35.0 0.0.0.255 host 192.168.35.66″ will only let network 192.168.35.0/24 access accounting server whilst prevent traffic from other networks.

Question 4:

A host with the address of 192.168.125.34/27 needs to be denied access to all hosts outside its own subnet. To accomplish this, complete the command in brackets, [access-list 100 deny protocol address mask any], by dragging the appropriate options on the left to their correct placeholders on the right.

accesslist2


Answer:

1) ip

2) 192.168.125.34

3) 0.0.0.0

Full command: access-list 100 deny ip 192.168.125.34 0.0.0.0

Question 5:

Drag and drop the network user application to the appropriate description of its primary use (not all options are used)

networkapplication


Answer:

1) web browser

2) instant message

3) e-mail

4) database

5) collaboration

Question 6:

This topology contains 3 routers and 1 switch. Complete the topology.

Drag the appropriate device icons to the labeled Device




Drag the appropriate connections to the locations labeled Connections.

Drag the appropriate IP addresses to the locations labeled IP address

(Hint: use the given host addresses and Main router information)

To remove a device or connection, drag it away from the topology.

Use information gathered from the Main router to complete the configuration of any additional routers. No passwords are required to access the Main router . The config terminal command has been disabled for the HQ router. The router does not require any configuration.

Configure each additional router with the following

Configure the interfaces with the correct IP address and enable the interfaces.




Set the password to allow console access to consolepw

Set the password to allow telnet access to telnetpw

Set the password to allow privilege mode access to privpw

Note: Because routes are not being added to the configurations, you will not be able to ping through the internetwork.

All devices have cable autosensing capabilities disabled.

All hosts are PC’s

    subnet-zero = first and last subnets on a network that has been split into subnets. you are allowed to use these 2 subnets by default on modern cisco devices

    Q.1 on ICND2 test

  12. taffybouy
    January 28th, 2013

    Question 1 is not right, it can’t be……

    I assume the first usable IP is in use for the interface in question (can’t get any router to give me any partial config by hovering)

    If the above is correct then how can you move from a IP of 192.168.164.149/27 to the next subnet which is less than 32 away i.e 192.168.164.166/28 which should be 192.168.164.180/28

    Maybe I’m missing something important from the router configs?

    Won’t work on firefox, chrome or explorer

  13. hi all
    February 1st, 2013

    ip subnet-zero command allow you to use first and last sub network :)
    Since Cisco by default providing it hence you don’t need to configure this command any more as far as mentioned in question.

    Is it actually a lab question?

  26. Jelena
    April 12th, 2013

    Hi, I have passed CCNA week ago, with score 1000/1000 :)
    Exam was easy, all questions known, labs were ACL2, EIGRP and VTP.
    For preparing I’ve used Cisco CCNA Exploration curriculums, Odom’s books, 9tut, Spike and Acme dumps.
    My advise is first go through all subjects in Odom’s books or
    exploration curriculum, try to pick up all concepts, then go through 9tut questions and labs, if you have any doubts go back to book, and in the end practise some dump to gain in speed.
    There were sume bugs in VTP sim, try to give it same time to stabilize, and then try again.
    Thanks a lot to 9tut and examcollection!!!
    And very best to all of you :)

    p.s. If anyone have questions I’ll try to help so ask ;)

    Hi,
    I’m new to the site and find it very helpful so far..I’m studying for my CCENT (ICND-1)….
    What are the 4 SIMS that can come up on the Exam?
    I want to chose the 2 exam option..

    I got told that STP, ACLs, Vlans and Nat are all ICND 2 (not ICND-1)
    where can I get definitive ICND-1 questions only?
    Right now, I am slightly confused and need to know what to study for ICND-1 and what not to study for ICND-1.

    THanks for your help.

  33. ace me
    May 16th, 2013

    I’m confused. On question number one, when submitting for the hosts aren’t you borrowing from the right? When subnetting for networks you borrow from the left using the equation (2^n-2). When submitting for hosts you use the equation (2^n) only. If you need five hosts then it should be /27. If you need 16 hosts then it should be /29. If you need 11 hosts then it should be /28.

    And to make it a bit more complicated, technically if you only need 16 hosts, you would use /28. However this would not leave room for expansion. Am I missing something?

    The /30 is correct because we need 2 networks not hosts. In this case we would use the equation 2^n-2

  34. Michal
    May 20th, 2013

    @ace me
    /28 = 14 hosts. always remember about network and broadcast addresses.
    for 16 hosts you should use /27 subnet masks

    About question 4.

    It needs to be denied access to all hosts outside its own subnet but I am confused the answer is: access-list 100 deny ip 192.168.125.34 0.0.0.0

    and I thought to deny all the subnet better put the subnet address 192.168.125.32.
    So access-list 100 deny ip 192.168.125.32 0.0.0.0

    hello ! 9tut Guys, thenx so much for ur awesome and unquantifiably biulful materials,GLORY TO GOD FOR UR EXISTENCE, I passed yesterday with 881/1000, all questions were from 9tut and spike dumps, with approximately minor modifications.

    simulations were : ACCESS-LIST2, VTP, AND EIGRP-
    (EIGRP sim had alot of problems in configurations, the second router was not responding during confinguration so i decided to leave it),

    Qn 465 Spike What is effect of no login command?

    The answers provided are
    a) Telnet access is denied.
    b) Telnet access requires a new password at the first login.
    c) Telnet access requires a new password.
    d) There is a virtually limitless supply of IP addresses.

    Ans is a)
    But in reality this implies no password is required for login. Please check on your routers!!
