N10-005 Question #165: Real Exam Question with Answer & Explanation

The correct answer is D: Physical layer. The lowest layer of the OSI Reference Model is the physical layer, which is responsible for the "nitty gritty" details of transmitting information from one place to another on a network. The layer just above the physical layer is the data link layer, called the network interface

Question

The network interface layer of the TCP/IP model corresponds with which of the following layers of the OSI model? (Select TWO).

Options

ATransport layer
BNetwork layer
CSession layer
DPhysical layer
EPresentation layer
FData link layer

Explanation

The lowest layer of the OSI Reference Model is the physical layer, which is responsible for the "nitty gritty" details of transmitting information from one place to another on a network. The layer just above the physical layer is the data link layer, called the network interface layer or just the link layer in the TCP/IP architectural model. Its primary job is to implement networks at the local level, and to interface between the hardware-oriented physical layer, and the more abstract, software- oriented functions of the network layer and those above it.
