B – Prefix Length is correct.
If you have a questrion – what makes the route unique: PREFIX LENGTH, this is foundation
AD or metrics is addituonal attribute
A.
The question was asked incorrectly.
B is correct. The longest-match will always win.
Correct answer is A
When building the RIB, by default, the routing protocol with the lowest administrative distance value will always win when the router is determining which routes to place into the routing table. For example, if a router receives the 10.0.0.0/8 prefix via external EIGRP, OSPF, and internal BGP, the OSPF route will be placed into the routing table. If that route is removed or is no longer received, the external EIGRP route will be placed into the routing table. And finally, if both the OSPF and external EIGRP routes are no longer present, the internal BGP route is used.
No, it is B
