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.

It assists in protocol design. It prevents technology in one layer from affecting other layers.
