GRE Multilink Sim

October 20th, 2016 in LabSim Go to comments

Refer to the topology below and answer the following questions.

Topology.jpg

Question 1

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

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

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

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.

    Failed ICND2 exam today. It is indeed hard and run out of time also.

    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 just took and failed 200-105 test. There was a question on it about SNMP and OID, I don’t remember it exactly, been looking for info on it everywhere with no luck. Does anyone out there remember the question I’m referring to? Would really like to know.

    Yes, you’ll fail it first time. Not an easy test. Eventually you will succeed.

    For the ICND1 should we be going through the Composite Quizzes also?

    ICND1 – Composite Quizzes
    ICND1 – Security Testlet Simulator
    ICND1 – Show Configuration Simulator
    ICND1 – DHCP Simulator

    Failing is not an option, specially when you’re short on cash!
    Study hard and test your knowledge on regular questions and do the labs and understando how to troubleshoot them and you will pass in 1st attempt!

    Which feature can you use to restrict SNMP queries to a specific OID tree?

    I got it wrong! right answer is “a view record”

    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.

    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.
