What are two benefits of using a layered network model? (Choose two.)
- It assists in protocol design.
- It speeds up packet delivery.
- It prevents designers from creating their own model.
- It prevents technology in one layer from affecting other layers.
- It ensures a device at one layer can function at the next higher layer.
Some vendors have developed their own reference models and protocols. Today, if a device is to communicate on the Internet, the device must use the TCP/IP model. The benefits of using a layered model are as follows:
- assists in protocol design
- fosters competition between vendors
- prevents a technology that functions at one layer from affecting any other layer
- provides a common language for describing network functionality
- helps in visualizing the interaction between each layer and protocols between each layer
