Answer 2

1. Distance Vector [routing with rumor]
2. Link State Protocol

Question 2

send their entire routing table to directly connected neighbors

Answer 2

Distance Vector [RIP]

Question 3

send information about directly connected links to all the routers in the network.

Answer 3

Link-State Protocol [OSPF]

Question 4

has some characteristics of a link state routing protocol, and some characteristics of a distance vector routing protocol.

Answer 4

Hybrid Protocol [EIGRP]

successor

Question 9

EIGRP - The metric value for the lowest-metric path to reach a destination.

Answer 9

Feasible distance (FD)

Question 10

EIGRP - The distance reported by a router to reach a prefix.
