Premium Member: You can test your knowledge with these questions first via this link.
[/am4show]
Note: If you are not sure about EIGRP, please read my EIGRP tutorial.
Question 1
[am4show have=’p2;’]What does a router do if it has no EIGRP feasible successor route to a destination network and the successor route to that destination network is in active status?
A. It routes all traffic that is addressed to the destination network to the interface indicated in the routing table.
B. It sends a copy of its neighbor table to all adjacent routers.
C. It sends a multicast query packet to all adjacent neighbors requesting available routing paths to the destination network.
D. It broadcasts Hello packets to all routers in the network to re-establish neighbor adjacencies.
Answer: C[/am4show]
Explanation
When a router has no EIGRP feasible successor and the successor route to that destination network is in active status (the successor route is down, for example) a route recomputation occurs. A route recomputation commences with a router sending a query packet to all neighbors. Neighboring routers can either reply if they have feasible successors for the destination or optionally return a query indicating that they are performing a route recomputation. While in Active state, a router cannot change the next-hop neighbor it is using to forward packets. Once all replies are received for a given query, the destination can transition to Passive state and a new successor can be selected.
(Reference: http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080093f07.shtml#rout_states)
Question 2
[am4show have=’p2;’]Which statements are true about EIGRP successor routes? (Choose two)
A. A successor route is used by EIGRP to forward traffic to a destination.
B. Successor routes are saved in the topology table to be used if the primary route fails.
C. Successor routes are flagged as ‘active* in the routing table.
D. A successor route may be backed up by a feasible successor route.
E. Successor routes are stored in the neighbor table following the discovery process.
Answer: A D[/am4show]
Question 3
[am4show have=’p2;’]Which type of EIGRP route entry describes a feasible successor?
A. a backup route, stored in the routing table
B. a primary route, stored in the routing table
C. a backup route, stored in the topology table
D. a primary route, stored in the topology table
Answer: C[/am4show]
Explanation
Feasible successor is a route whose Advertised Distance is less than the Feasible Distance of the current best path. A feasible successor is a backup route, which is not stored in the routing table but stored in the topology table.
Question 4
[am4show have=’p2;’]Refer to the exhibit. Based on the exhibited routing table, how will packets from a host within the 192.168.10.192/26 LAN be forwarded to 192.168.10.1?
A. The router will forward packets from R3 to R2 to R1
B. The router will forward packets from R3 to R1
C. The router will forward packets from R3 to R1 to R2
D. The router will forward packets from R3 to R2 to R1 AND from R3 to R1
Answer: D[/am4show]
Explanation
From the routing table we learn that network 192.168.10.0/30 is learned via 2 equal-cost paths (192.168.10.9 &192.168.10.5) -> traffic to this network will be load-balancing.
Question 5
[am4show have=’p2;’]Refer to the exhibit. Given the output from the show ip eigrp topology command, which router is the feasible successor?

Answer: B[/am4show]
Explanation
First we must notice that all the 4 answers are parts of the “show ip eigrp topology” output. As you can see, there are 2 parameters in the form of [FD/AD] in each answer. For example answer C has [46152000/41640000], it means that the FD of that route is 46152000 while the AD is 41640000.
To become a feasible successor, a router must meet the feasibility condition:
“To qualify as a feasible successor, a router must have an AD less than the FD of the current successor route“
In four answer above, only answer B has an AD of 128256 and it is smaller than the FD of the current successor route (41152000) so it is the feasible successor -> B is correct.
Question number confuses me…the explanation on this page says the FIRST number and the SECOND number are (FD/AD)
Yet on the EIGRP tutorial page, it says the FIRST number is and i quote “the metric from Router0 to the destination” and the SECOND number is the AD
Which is it?
Maybe you mean the output of “sh ip route”?
There you have [AD/Metric]
But C & D as well is the same concept which is AD is less than FD.
sorry I was wrong there. apology
in the sh ip route what you can see is ad/metric where AD is Administrative Distance not advertise distance.
Q4
In the output for #show ip route
should be
192.168.10.0 via 192.168.10.10 NOT 192.168.10.9
via 192.168.10.6 NOT 192.168.10.5
The address of the next hub routers is Wrong.
cheers
@Andrew your are right with that, the IP address of the next hop router in both case are wrong, but by other part, the answer option only say the Router Name, and no see problem about with this error in the figure. but its very important can see this error
@Andrew, and all, you know it’s funny ! we are studying ICND and CCNA for less than a year and I individually saw many mistakes in Cisco exams like above, in my ICND1 exam I found two mistakes during exam and I commented it, however those mistake didn’t change the answer but how come that such a huge company exam designer are acting like this ! Do they have CCNA ? 😀
( In my exam , in one Router , after running #sho ip int br , it shows an IP address for Fa0/0 while by running #sho inter fa 0/0 it shows slightly different one like one IP after that 😀 )
@Amir Reza, in my ICND1 test I haven the same error, Why cisco dont see that king of error
I can’t understand the explanation of Q5. It seems to me that the AD number is smaller in all the ratios for all possible answers here.
@ Kerim Mirek
Q1 is confusing me, too. I’ve also seen this question/answer on other sides but in my mind the text in the question is wrong (like you described) or the answer is wrong.
@ Kerim Mirek / Q1, again
I got the answer from a colleaguge.
Passive State means the router does not search for a new route (because the successor route or feasible route and related interface are working)
Active State means the router is searching for a new route (because the successor route and feasible route does not work, e.g the related interface is down)
BTW nailed my ICND2 with a perfect score now a CCNA!
To clear up some confusion for you for EIGRP the metrics/k values and AS do indeed have to match in order for two routers to form a neighbor Adjacency in EIGRP. The below I am pasting is directly from Cisco quick reference guide:
“Neighbor Discovery and Route Exchange
When EIGRP first starts, it uses hellos to build a neighbor table. Neighbors are directly attached routers that have a matching AS number and k values. (The timers don’t have to agree.) The process of neighbor discovery and route exchange between two EIGRP routers is as follows:”
@ Kerim.
in Q1, I think the point is that EIGRP will always search for a back-up (or feasible successor) route. In the question it mentions that the successor is “active” – i think they just mean “up and running”. If the successor is up and running, EIGRP will still search for a back-up route, for when the successor fails. If the successor route is down, it will search for a successor and a feasible successor..
i don’t think they just mis-typed *In*-active.
Took ICND2 earlier today, 986 / 1000.
Question 2 from this page was on there.
hi all
subscribe to that channel http://www.youtube.com/user/Joynetworks for free
thanks
2,3 were there
Passed today my ICND@2 by 1000. Got different configuration of the Eigrp & frame Relay labs where there were different DLCIs and IP addresses, but same process was used to get answers (show commands, show ip protocols, show ip interface brief ).
A question about GLBP and a question about netflow were on my test. You can find them here: http://www.examtut.com/2013/09/new-questions-in-ccna-200-120-hsrp-vrrp.html
Study 9tut and this guy i found him really helpful. He has unique way of teaching http://www.danscourses.com If you can do all his videos again and again. Trust me you will get the concept. Also one thing i learned today is if you don’t know the concept it’ll be hard for you in the exam.
All the best to every one in their path. Keep me in your good wishes.
Q5 changed a bit, an entry was shown with FD like
172.16.1.1 (Serial0.1), from 10.0.0.2, Send flag is 0x0
Composite metric is (53973248/128256), Route is Internal
after applying feasible successor rule, in options you had to select which route is successor route
a.
b.
c. 172.16.1.1
d. 10.0.0.2
Took the exam today. Pass 986/1000. Q2 were on there.
Thanks 9tut.
took the exam yesterday and passed with 1000/1000. 9tut is superb..many questions from here. There was one question related with EIGRP Feasible successor network which was not mentioned .
Find the network which is feasible successor
R3# show ip eigrp topology
IP-EIGRP Topology Table for AS(1)/ID(3.3.3.3)
Codes: P – Passive, A – Active, U – Update, Q – Query, R – Reply,
r – reply Status, s – sia Status
P 10.0.13.0/24, 1 successors, FD is 2560
via Connected, Serial1/0
P 10.0.23.0/24, 1 successors, FD is 2560
via Connected, Serial1/1
P 10.0.45.0/24, 2 successors, FD is 3840
via 10.0.34.4 (3840/1280), Serial1/2
via 10.0.35.5 (3840/1280), Serial1/3
P 10.0.34.0/24, 1 successors, FD is 2560
via Connected, Serial1/2
P 10.0.35.0/24, 1 successors, FD is 2560
via Connected, Serial1/3
P 192.168.5.0/24, 1 successors, FD is 3072
via 10.0.35.5 (3072/512), Serial1/3
via 10.0.34.4 (4352/1792), Serial1/2
No idea how you got the answer to question 5.
EIGRP will pick the 2nd best route to be the feasible successor. To me that seems like answer C where the FD is way lower then the FD is answer b
@Simon EIGRP looks at the advertised distance (after the slash) for choosing a feasible successor not the feasible distance (before the slash) of the potential route.
Tested today, 8/20. #2, 4 were on there.
Me either just can’t seem to understand Q5 for nothing…
Also for Question 5. We can easily guess B is the answer just because the question says 1 Successor and the Answer B has Hop Count as 1 and all the other options have Hop Count as 2.
took the exam today and pass with 907. Question 2 and 4 were on there.
location United States Florida.
test ICND 2

Got 1000 today, thanks to 9tut
A new EIGRP question came up that i had not seen before,
cant remember it completely but it gave either 3 or 4 routers, A, B, C & D
with a number of networks, all routers were EIGRP enabled & no auto summary in the config
you needed to give the ip addresses that would appear in A’s routing table (pick 3 of 6)
so understand vlsm & possibly summarization (if the question changes)
Sorry I don remember more but i wasnt concentrating on remembering the questions!
Q3 on my exam today
hello; the questions 5 ; this answer is B ? Is Correct ?? thanks
Going to take exam at 11:30 today..nervoused..:(
question 5 : Yes answer is B
128256 < 41152000
To be FS your AD most be lower than the FD of the successor
Hello chris, how did it go . Pls share with us. Thanks.
Q4 was there
passed on 3/13. question 3 on it. tks 9tut
Q1 it should state “inactive” not ” in active” two very different things.
Q1 is written correctly and the answer is C. When a route in the EIGRP topology table has a status of “A” for active, that means the router is actively looking to confirm a route to that network with its neighbors. The way EIGRP actively looks is by querying its EIGRP neighbors. In the topology table “A” is bad and “P” is good (P means passive or “stable”.)
I got Q2, Q3, Q4 today in my ICND2 exam.
Thanks 9tut.
Had a new EIGRP question.
It showed a topology with 4 routers configured in the same AS.
They all had auto summary enabled and had IPs from class A, B and C assigned across their interfaces.
Question was which EIGRP routes would appear in the R1 routing table.
Selected the 3 classFULL addresses (/8, /16 and /24) and passed with 1000 🙂
GO LOOOK AT 9tut CCNA EIGRIP THIS ICND2 study page is missing questions. And know your k weights I had a 1 question on them
And the post above me is on test
Got Q4 today in Moscow.
guys download dumps with nuggets free from this following link
wurl. cc/dumps
Just took the test today – 980/1000 ALL 5 questions came from this page. Thanks 9tuts! Also got Frame Relay, EIGRP and OSPF labs
THERE IS NO NEED FOR ANY DUMPS – just study one book (Wendel or Todd) and the you tube lessons available free for visual knowledge. Along with 9tuts these are enough for 900 and over marks with ease.
But you MUST understand the concepts and not mug up the answer as they change the options and answers
@all: We had to move all the questions and answers out of 9tut. We can only keep the explanation. You can download the questions and answers at: https://mega.co.nz/#!oIdESYbD!yyu33vygrfKPy4rcmcbV6qW2fxINNoTokuDM3CjA_og
@9tut everytime I try downloading the file it gives me a error.
@Anonymous: You can use this link instead: http://www.4shared.com/office/WXdZDq7Xce/ICND1_2_Questions_July_2015.html
Hey thank you for this website. Some of the stuff in my Cisco press books didn’t even cover things that were on the test like the hello and dead timers for OSPF. Maybe my books were old, I don’t know. Thanks again for this website it really helped me understand what I was looking at and it made a bunch of things clear. It’s worth it folks but don’t just memorize, you need to actually understand whats happening. I used CBT Nuggets, Youtube, Cisco Press ICND1 and ICND2 books and 9Tut.
9tut – I am not able to access the page for “CCNA”. Please help. It is throwing an error!
Hi,
plz send me a link icnd2 lab question.
please can you include the questions and the explanation together for clarification? thanks
Just to echo what Godwin said – any chance we could get the questions that go with the answers please? Thanks
can some one explain again for question where it asked the feasible successor?? i think its question 3? also where can i find virtual test simulator?
Hi all,
can someone send me the dumps for icnd to krimlakh at h o t m a i l
