Question

What layer does Protocol OSPF belong to in the DOD model? and in the OSI Model? Port#? What does it stand for and what does it do?

A) DOD Model: Internet Layer, OSI Model: Network Layer, Port# 89, Stands for Open Shortest Path First, interior gateway protocol for routing.
B) DOD Model: Host-to-Host Layer, OSI Model: Transport Layer, Port# 89, Stands for Open Systems Protocol Framework, manages network communication.
C) DOD Model: Network Access Layer, OSI Model: Data Link Layer, Port# 89, Stands for Open Shortest Path First, calculates the shortest path in a network.
D) DOD Model: Application Layer, OSI Model: Application Layer, Port# 89, Stands for Open Systems Protocol Framework, supports application-level interactions.

Answer 1

The OSPF protocol belongs to the Internet Layer in the DOD model and the Network Layer in the OSI model. It uses port number 89 and stands for Open Shortest Path First, which is an interior gateway protocol for routing.

Step-by-step explanation:

The correct answer is A) DOD Model: Internet Layer, OSI Model: Network Layer.

OSPF stands for Open Shortest Path First and it is an interior gateway protocol for routing. It works at the network layer in the OSI model and the internet layer in the DOD model.

The protocol uses port number 89 to communicate and calculate the shortest path in a network.
