Study the exhibit carefully. In this network, if all required configurations are true for routing. Subnet
10.1.1.0/24 is sourced by RA and advertised via BGP, OSPF, and EIGRP. Finally, RG knows this
subnet. Which routing protocol and administrative distance can be used by RG to reach subnet
10.1.1.0/24?
A.
EIGRP, AD 90
B.
EIGRP, AD 170
C.
OSPF, AD 110
D.
BGP, AD 20
Explanation:
Administrative distance is the feature that routers use in order to select the best path when there
are two or more different routes to the same destination from two different routing protocols.
Administrative distance defines the reliability of a routing protocol. Each routing protocol is
prioritized in order of most to least reliable (believable) with the help of an administrative distance
value.
