You have two paths for the 10.10.10.0 network - one that has a feasible distance of 3072 and the other of 6144. What do you need to do to load balance your EIGRP routes?
A.
Change the maximum paths to 2
B.
Change the configuration so they both have the same feasible distance
C.
Change the variance for the path that has a feasible distance of 3072 to 2
D.
Change the IP addresses so both paths have the same source IP address
They were claiming that they have removed EIGRP from blueprints, as i guess they just lied out there...there are lot of deep/detailed questions about EIGRP which i have not met neither in Wendell Odom nor on Netacad.
Word on the street is that ExamTopics just bundled the old CCNA exam questions into the 200-301 category. So a lot of this material won't actually be on the exam.
No BC is incorrect ! Yes, EIGRP does allow equal path and unequal path load balancing , but you can't change feasible distance, only one answer is requested therefore it's C only
it´s C
Variance needs to be changed to make the feasible distance of the 6144 path within the feasible distance of the 3072 path. In this case, a variance of 2 would make the feasible distance of the 3072 path within twice the feasible distance of the 6144 path, thus allowing for load balancing.
BC are correct choice here.
B: By changing the the configuration and make feasible distance same for both, will enable ECMP (Equal Cost Multiple Path) Load-balancing. It will load balance the traffic.
C: By changing the Variance by 2 (Means allowing other feasible distance upto x 2) of 3072.
In other words, If I apply variance 2 on 3072, I'm allowing other distance by to 6144 can be Load- balance. This is called Enequal-cost load-balancing. which is only supported by EIGRP. I hope this helps.
I believe the answer should be C. Variance is something used to create unequal cost load balancing. I've never read anything that just says to change the configuration so they have the same feasible distance. Using variance is practically an EIGRP staple.
From what I understood, both B and C represent the same thing, i.e., by changing variance to 2 allows value to be same(2*3072=6144) which is C & B states to change the configuration to achieve same feasible distance which is if variance 2 is given both will have the same feasible distance. So I guess the answers are correct.
Can someone explain the answer?
I would assume only C is a correct solution:
B: is feasible distance not a calculated number?
“feasible distance: Best metric among all path to a network. It is calculated by adding the advertised/reported distance advertised by the neighbor and the cost calculated by that current router to reach the neighbor.”
https://www.geeksforgeeks.org/eigrp-cost-calculation/
C: Makes sense since 3072 multiplied by variance 2 is 6144
https://study-ccna.com/eigrp-authentication-load-balancing/
I would say its only B. The Distance needs to be the same but not forced 2.
Probaly both are right but B is the better answer.
However there are just 4 answers and no "Choose two".
is true, from the same source of LTTAM here is the answer: Every routing protocol supports equal cost path load balancing. In addition, Interior Gateway Routing Protocol (IGRP) and EIGRP also support unequal cost path load balancing
