Premium Member: You can practice this sim with our simulator here.[/am4show]

Refer to the topology below and answer the following questions.

Topology.jpg

Question 1

[am4show have=’p2;’]Why is the Branch2 network 10.10.20.0/24 unable to communicate with the Server farm 1 network 10.10.10.0/24 over the GRE tunnel?

A. The GRE tunnel destination is not configured on the R2 router.
B. The GRE tunnel destination is not configured on the Branch2 router.
C. The static route points to the tunnel0 interface that is misconfigured on the Branch2 router.
D. The static route points to the tunnel0 interface that is misconfigured on the R2 router.

 

Answer: C[/am4show]

Explanation

The Branch2 network is communicating to the Server farm, which is connected to R2, via GRE Tunnel so we should check the GRE tunnel first to see if it is in “up/up” state with the “show ip interface brief” command on the two routers.

On Branch2:

Branch2_show_ip_interface_brief.jpg

On R2:

R2_show_ip_interface_brief.jpg

We see interfaces Tunnel0 at two ends are “up/up” which are good so we should check for the routing part on two routers with the “show running-config” command and pay attention to the static routing of each router. On Branch2 we see:

R2_show_run_static.jpg

The destination IP address for this static route is not correct. It should be 192.168.24.1 (Tunnel0’s IP address of R2), not 192.168.24.10 -> Answer C is correct.

Note: You can use the “show ip route” command to check the routing configuration on each router but if the destination is not reachable (for example: we configure “ip route 10.10.10.0 255.255.255.0 192.168.24.10” on Branch2, but if 192.168.24.10 is unknown then Branch2 router will not display this routing entry in its routing table.

Note: The IP address or configuration may be different in the exam.

Question 2

[am4show have=’p2;’]Why has the Branch3 router lost connectivity with R1? Use only show commands to troubleshoot because usage of the debug command is restricted on the Branch3 and R1 routers?

A. A PPP chap hostname mismatch is noticed between Branch3 and R1.
B. A PPP chap password mismatch is noticed between Branch3 and R1.
C. PPP encapsulation is not configured on Branch3.
D. The PPP chap hostname and PPP chap password commands are missing on the Branch3 router.

 

Answer: A[/am4show]

Explanation

First we should check Branch3 (and R1) with the “show ip interface brief” command to find any Layer1/Layer 2 issue.

Branch3_show_ip_interface_brief.jpg

We see the interfaces connecting between them are in “up/down” states which indicates an Layer 2 issue so we should check the configuration of these interfaces carefully with the “show running-config” command and pay attention to these interfaces.

R1_show_run_interface.jpg

and on Branch3:

Branch3_show_run_interface.jpg

We learn from above config is R1 is using CHAP to authenticate Branch3 router (via the “ppp authentication chap” command on R1). Branch3 router is sending CHAP hostname “Branch_3” and CHAP password “Branch3_Secret!” to R1 to be authenticated. Therefore we should check if R1 has already been configured with such username and password or not with the “show running-config” command on R1:

R1_show_run_username.jpg

On R1 we see the configured username is “Branch3”, not “Branch_3” so the usernames here are mismatched and this is the problem -> Answer A is correct.

Question 3

[am4show have=’p2;’]Which statement about the router configurations is correct?

A. PPP PAP is authentication configured between Branch2 and R1.
B. Tunnel keepalives are not configured for the tunnel0 interface on Branch2 and R2.
C. The Branch2 LAN network 192.168.11.0/24 is not advertised into the EIGRP network.
D. The Branch3 LAN network 192.168.10.0/24 is not advertised into the EIGRP network.
E. PPP CHAP is authentication configured between Branch1 and R1.

 

Answer: D[/am4show]

Explanation

In this question we have to check each option to see if it is correct. When we check Branch3 router we notice that “network 192.168.10.0” command is missing under “router eigrp 100” -> Answer D is correct.

Branch3_show_run_eigrp.jpg

Question 4

[am4show have=’p2;’]Why did Branch1 router lose WAN connectivity with R1 router?

A. The IP address is misconfigured on PPP multilink interface on the Branch1 router.
B. The PPP multilink group is misconfigured on the Branch1 serial interfaces.
C. The PPP multilink group is misconfigured on the R1 serial interfaces.
D. The Branch1 serial interfaces are placed in a shutdown condition.

 

Answer: A[/am4show]

Explanation

This question clearly stated there is a WAN connectivity issue between R1 and Branch1 so we should check both of them with the “show ip interface brief” command. On R1:

R1_show_ip_interface_brief.jpg

On Branch1:

Branch1_show_ip_interface_brief.jpg

We can see that although the Multilink1 interfaces are in “up/up” state but they are not in the same subnet. According to the IP address scheme shown on the topology we can deduce the Multilink interface on Branch1 has been misconfigured, it should be 192.168.14.2 instead.

  10. failed01
    February 8th, 2017

    This sim was on the exam, but I remembered my answered on Q1 was b, because I saw there was no tunnel destination configure on the tunnel. Is it right or wrong?

  11. failed01
    February 8th, 2017

    As for Q2 my answer was d, because when I show run I did not see the ppp chap username and ppp chap password on Branch3 serial interface configuration. I guess they frequently change the content of the sims configuration even though same scenario, question, and topology.

    I need to get this in my exam, seems to be a really easy one – Only 2 commands, show ip interface brief and show running-config. But yeah, need to know the concepts which by the explanation given here is clear and crisp. Fingers crossed this should come.

  31. AFRICA
    July 31st, 2017

    Hi all, I would like to share my little experience with you. I had no IT background but engaged in CCNA self-study since 1st march 2017. I took and passed ICND1 on June 7th (864/832). I have just passed ICND2 today (895/811). I have come to understand that studying and understanding the concepts is first step. The second step is to practice as much as needed (I have only used Packet Tracer). I you have some video or voice tracks, listen to them continually (on the go or at home). Start with dumps when you have learned and nailed all the concepts. 9TUT is the best (for me), here you have all you need to have a good idea of the Exams contents. BUT, understanding the concepts and practicing are better than anything (both for exam preparation and work experience).

    For ICND2, I have had three simlet (EIGRP, OSPF and GRE). Attention, Cisco is changing composition of questions and answers. So, use your sh run, sh ip int brief and sh ip route (and any other cd if necessary) to gather all the facts. For other questions, you might find 80% or less of 9TUT questions in the exam.

    Good luck

    Good Day,

    If I miss or get one question wrong per lab sim on the actual exam, will I still have a change to pass ICND2? Because I tried answering the Sims Here with my basic knowledge without reading the explanation yet.

    OSPF = 30/40
    EIGRP = 40/40
    GRE/multilink = 30/40

    And total it with my obtained say 80 percent from the multiple choice questions.

    What I’m asking is how are the points distributed.

    THank you all.

    Hi All and 9tut,
    Nice explanation however;
    on GRE multilink Sim question 1, the correct answer is marked as C. however looking at the routing table of the branch router does not show a static route. And the results of sh ip route does not list the server farm 10.10.10.0/24 network as indicated in the explanation section. is there anything I am missing ?

  62. @Alen
    May 3rd, 2018

    I also caught that along with the overall explanation using Branch 2 while the sim question uses Branch 1. This might be the reason for you second guessing yourself.

    If you go by Branch 2 then yes “ip route 10.10.10.0 255.255.255.0 192.168.24.10” is the wrong ip. If you go by Branch 1 the tunnel statement should be right under “no ip http secure-server” but it isnt.

    I did my ICND2 today and passed, after the 2nd attempt. From my own personal experience, Dumps are just there for guidance, they do not actually guarantee you to pass. If you relied too much on dumps it will actually stop you from studying hard. The questions keep changing, the lab sim are still much valid. EIGRP, OSPF and Gre. There was some drag and drop about K values in EIGRP and some on cloud virtualization. Many new questions that i have not seen on any of the dumps I used but overall, if you can actually study all the questions on this site, you properly going to pass. There are some new questions on SPAN, what protocol will block DHCP from passing STP, VTP, 80.2.1Q and DTP. Any question on APIM IP SLA. IPV6 OSPF questions as well. Thanks 9tut. Am sharing this information because I gained a lot from people who shared their experience earlier, this gave me the motivation to study the more.

    Explanation

    On R4 we see EIGRP is configured with AS 2 (router eigrp 2) while other routers are using AS 1 (router eigrp 1). Therefore R4 cannot see other routers and vice versa.

    I only see the explanation no question.
