Question

In EIGRP best path is known as the successor, where as backup path is known as __________

(a) Feasible successor

(b) Back-up route

(c) Default route

(d) There is no backup route in EIGRP

This question was addressed to me during an interview for a job.

My enquiry is from EIGRP topic in section Point to Point Protocol & Error Detection of Computer Network

Answer 1

Correct answer is (a) Feasible successor

To elaborate: Feasible successor is the backup path. The backup path is used alternatively used whenever the best path fails. It is not used primarily because it is comparatively expensive than the best path.
