EIGRP Troubleshooting Sim
Question
Refer to the topology. Your company has connected the routers R1, R2 and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.
The EIGRP routing protocol is configured. You are required to troubleshoot and resolve the EIGRP issues between the various routers. Use the appropriate show commands to troubleshoot the issues.
Instead of posting the output of “show run” commands we post here the commands entered on each router to reduce some useless lines. Also you can try solving questions by yourself before reading the answers.
| R1: int lo0 ip address 10.1.1.1 255.255.255.255 int e0/0 ip address 192.168.16.1 255.255.255.0 int s1/1 ip address 192.168.13.1 255.255.255.0 bandwidth 1000 int s1/3 ip address 192.168.12.1 255.255.255.0 ! router eigrp 1 network 192.168.12.0 network 192.168.13.0 network 192.168.16.0 |

Note: In the exam, this sim uses IOS version 15 so “no auto-summary” is the default setting of EIGRP. You don’t have to type it.

Question 1
The loopback interfaces on R4 with the IP addresses of 10.4.4.4/32, 10.4.4.5/32 and 10.4.4.6/32 are not appearing in the routing table of R5. Why are the interfaces missing?
A. The interfaces are shutdown, so they are not being advertised.
B. R4 has been incorrectly configured to be in another AS, so it does not peer with R5.
C. Automatic summarization is enabled, so only the 10.0.0.0 network is displayed.
D. The loopback addresses haven’t been advertised, and the network command is missing on R4.
Answer: B
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.
Question 2
Which path does traffic take from R1 to R5?
A. The traffic goes through R2.
B. The traffic goes through R3.
C. The traffic is equally load-balanced over R2 and R3.
D. The traffic is unequally load-balanced over R2 and R3.
Answer: A
Explanation
For this question we have to check the routing table of R1 to find out the answer. Use the “show ip route” command on R1 we will get something like this:
There are three interfaces on R5 which are Loopback0: 10.5.5.5 ; Loopback1: 10.5.5.55; Ethernet0/0: 192.168.123.5 and all of them are advertised via 192.168.12.2 so we can conclude traffic from R1 to R5 goes through R2 (192.168.12.2 is the IP address of S2/1 interface of R2).
Note: Maybe there is another version of this question in the exam in which the answer should be “The traffic is equally load-balanced over R2 and R3″. Therefore please check the “show ip route” output carefully to see if there are more than one route to the destination.
Question 3
Router R6 does not form an EIGRP neighbor relationship correctly with router R1. What is the cause for this misconfiguration?
A. The K values mismatch.
B. The AS does not match.
C. The network command is missing.
D. The passive-interface command is enabled.
Answer: C
Explanation
From the configuration of R6 we learn that R6 is missing “network 192.168.16.0″ command (the network between R1 & R6) under EIGRP so EIGRP neighbor relationship will not be formed between them.
Question 4
Study the following output taken on R1:
| R1#ping 10.5.5.55 source 10.1.1.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.5.5.55, timeout is 2 seconds: Packet sent with a source address of 10.1.1.1 . . . . . Success rate is 0 percent (0/5) |
Why are the pings failing?
A. The network statement is missing on R5.
B. The loopback interface is shut down on R5.
C. The network statement is missing on R1.
D. The IP address that is configured on the Lo1 interface on R5 is incorrect.
Answer: C
Explanation
R1 does not advertise its loopback 0 (10.1.1.1) to EIGRP therefore a ping to destination 10.5.5.55 (R5) from 10.1.1.1 will not be successful because R5 does not know how to reply to R1.
small correction
ping 10.5.5.55 from R1 router it wil ping
but
ping 10.1.1.1 from R5 router it will not ping
pls check and update pls
I have gotten Watson working on version 1.1.7 (older) of VCE Player.
It should now work for people who’ve gotten the error “this exam was created with a later version of…”
I’m going to leave the .vce file up on Dropbox for 1 hour.
Can someone please download it and try it out?
Let me know if it’s working correctly, and what version of VCE player you used to test it.
If it works for others, I’ll upload it to a permanent place, for all.

Hello Everybody,
Anyone could send me the latest drum please in my email: hasanmon786@gmail.com
My exam on 26th of December.
Thanks
passed yesterday (15 December) with score 1000.
sims (ACL1 & ACL2 & Eigrp AS 112)
note : in the EIGRP simulation , you have to configure two routers, central1 and central2.
central2 router is pre-configured with the wrong AS number , so you have to disable it first and then configure it with AS 112 , this router has 3 fa interfaces , when you add them to EIGRP don’t use the interface IP and wildcard 0.0.0.0 , because it wont work , instead use wildcard of 0.0.0.255
on central1 router you will only enable EIGRP on the interface connected to central2 router.
GOOD LUCK.

Can someone tell me what to expect on the SIM’s, all of the ones here have problems and find the correct answer, like any other question, but the SIM’s on the Cisco site shows the SIM’s as being find the problem and fix it. Actually there are two types of SIM’s one that is fix, like in the example of changing the router name and then there are the Simlets where apparently you use the show commands to find the problem and answer the questions. That is pretty straight forward, but the other SIM’s i am still not sure what to expect for problems and how many. can someone explain?
guys a very quick question, has anyone taken the CCNA for the second time? if you did, can you please tell me which lab you did in you exam. Any one has any idea. Thank you.
@ Anonymus: you go “ping” ENTER and then specify the source, destination etc (in enable mode)
@ Rick: I follow comments on this page for a while, as I have my CCNA 200-120 next week. By the looks of things people get the following SIMs lately: ACL1, ACL2, this EIGRP or the other EIGRP one from this site. There seems to be anything between 50 and 60 questions on the exam. 3 big SIMs, lots of multiple/single choice and some small Simlets. I’m studying from Watson dump from ExamColletion – as lot of comments point to that one being valid 100% (plus this is the only one that works on my iPad :)
Hope this approach works :D
Someone correct me if I’m wrong here…
PS: Additional to Watson Dump people seem to get one Ether-channel question that’s not in the dump. Google it.
Can anyone send the latest dump in pdf to Arcell_m@yahoo.com? Am taking the exam this week.
What i was actually looking for is the ACL1 SIM, the one on here is just a SIM with questions and not a CLI SIM that you troubleshoot and correct. So i’m a bit confused as to what that ACL 1 is.
