There is no two-layered OSI model in CCNA.
7-layer there is (physical, link, network, transport, session, presentation, application).
4-layer there is (physical, network, transport, application), being the first an abstraction of physical+link and being the last an abstraction of session, presentation and application. This model is used because of the CCNA point of view, having no relevant meaning the abstracted layers.

Which two layers of the osi model have the same function as the TCPIP?
physical and data link
Which two layers of the OSI model describe the same functions as the transport and internet layers of the TCP IP model?

What 2 OSI layers are considered to be implemented in hardware?
the first two layers of OSI model i.e. physical layer & data link layer are involved in hard ware installation.
In which two layers of the osi model do NIC's belong?
NIC's can perform in the Data Link Layer of the OSI model. However, they can also perform services in the Physical Layer.(Network+ Guide to Networking Answer)Physical and Data Link layers

Discuss role of protocols at different layers of the OSI model?
Protocols at each of the OSI layers govern how they are to talk to each other. Each layer of the OSI model has different responsibilities and they may have multiple protocols that they could use. The sender and receiver in networks must agree on a common ground for communication, which is the protocol. Depending on what you are trying to accomplish there are different protocols at different layers of the OSI model. Basically, you need the two systems to agree on how to do that. That is the role of a protocol.
What layer is supdivided into two sub layers in the OSI model?
Layer 2 is divided into the LLC and MAC sublayers.
What layers of the OSI model are implemented in hardware?
The physical and link layers (layers 1 and 2) are implemented in hardware. The remaining five layers use these two layers to communicate across a network, and are done by software.
