Your colleague at work is confused about the protocols running on the Network Layer of the OSI model and the Network Access Layer of the TCP/IP model and which layer refers to which layer. To help out, how would you explain the difference between the two layers and what protocol operates on each? (Choose two)

Both Network Layer and Network Access Layer refers to the Layer 3 of the OSI model and Layer 3 of the TCP/IP model

Network Access Layer of the TCP/IP model refers to both the Physical Layer and Data Link Layer of the OSI model; some protocols are Frame Relay, and ATM

Network Access Layer of the TCP/IP model refers to the Network Layer of the OSI model; some protocols are Frame Relay, and ATM

Network Layer of the OSI model refers to the Internet Layer of the TCP/IP model; some protocols are EIGRP, OSPF, BGP

Network Layer of the OSI model refers to the Internet Layer of the TCP/IP model; some protocols are Frame Relay, and ATM

Explanation

The Network Access Layer of the TCP/IP model defines a way to transmit frames across the physical connection. This layer is related to the two lower layers of the OSI model; the Physical layer and the Data Link layer. Some protocols involved in this layer are ATM, Ethernet, and Frame Relay. Network Layer of the OSI model refers to the Internet Layer of the TCP/IP model; some protocols are EIGRP, OSPF, and BGP. The Application Layer of the TCP/IP model defines a way for users to interact with applications (programs). The Internetwork Layer provides routing mechanism for messages across the internetwork. The Transport layer is responsible for providing end-to-end communication through extended two-way conversation.
