Which two statements about the purpose of the OSI model are accurate? (CCNA 200-301)
Which two statements about the purpose of the OSI model are accurate? (Choose two)
A) Defines the network functions that occur at each layer.
B) Facilitates an understanding of how information travels throughout a network.
C) Changes in one layer do not impact other layer.
D) Ensures reliable data delivery through its layered approach.
Solution
Correct answer: A) Defines the network functions that occur at each layer and B) Facilitates an understanding of how information travels throughout a network.
The OSI model is designed to provide a conceptual framework that helps understand and describe how different network protocols interact and work together to provide network services. It does this by dividing the network communication process into seven layers, each with a specific function. This layered approach helps you understand the complexity of network communication by breaking it down into manageable parts. Furthermore, the model ensures reliable data delivery by defining how each layer contributes to the overall process of sending and receiving data in a network.
