CompTIA Network+ Network+ Routing Protocols and Concepts 2

Question 1

OSPF calculates the best path using which algorithm?

Accepted Answer

Dijkstra's Shortest Path First algorithm

Answer

OSPF uses Dijkstra's Shortest Path First (SPF) algorithm to build a complete map of the network and calculate the lowest-cost path to each destination.

Question 2

What is the maximum hop count allowed in RIPv2 before a route is considered unreachable?

Accepted Answer

15

Answer

RIPv2 allows a maximum hop count of 15; a hop count of 16 represents infinity and marks the route as unreachable.

Question 3

Which routing protocol divides networks into 'areas' to reduce routing overhead and improve scalability?

Accepted Answer

OSPF

Answer

OSPF uses a hierarchical area structure with Area 0 as the backbone, limiting LSA flooding and reducing the size of link-state databases in each area.

Question 4

Which two components does EIGRP use by default in its composite metric calculation?

Accepted Answer

Bandwidth and delay

Answer

EIGRP uses bandwidth and delay as its default metric components, though it can optionally include load, reliability, and MTU in the calculation.

Question 5

What does routing protocol 'convergence' describe?

Accepted Answer

When all routers in the network have consistent, accurate routing information

Answer

Convergence is the state where all routers in a network have synchronized, accurate, and consistent routing tables reflecting the current network topology.
