Refer to the exhibit. ROUTE.com has just implemented this EIGRP network. A network
administrator came to you for advice while trying to implement load balancing across part of
their EIGRP network.
If the variance value is configured as 2 on all routers and all other metric and K values are
configured to their default values, traffic from the Internet to the data center will be load
balanced across how many paths?

The variance is 2, the lowest metric is 30, so I would say answer is D. 4 ways:
10+10+10
20+10+10
20+20+20
40+10+10

AD 40 > FD 30, which means 20+20+20 can’t be FS. C is right.

Agree.
FS of ADEH is 30 then multiplies variance 2 equals 60, any route with FD metric less or equal 60 can be placed in routing table.
A+D+E+H
A+B+E+H
A+F+E+H
A+F+G+H
A+D+E+B+C+H 10+10+10+15+15=60
but “maximum-path” is in default, so no more than four paths are allowed.

Routes that are neither successor nor feasible successor (RD < FD) route can never be added to IP routing tables, regardless of the variance setting.
B+E+H RD=20
F+E+H RD=20
So only three routes can be used fol load balancing.

Not FS, but successor, sorry 🙂

I had issues with this one… we’re constructing Router A’s topology table, not H
