There is not universal agreement on the names of the layers in the TCP/IP networking model. Which of the following is one of the functions of the bottom layer which is sometimes called the Network Access or Link Layer?
There is not universal agreement on the names of the layers in the TCP/IP networking model. Which of the following is one of the functions of the bottom layer which is sometimes called the Network Access or Link Layer?
The bottom layer of the TCP/IP networking model, often called the Network Access or Link Layer, defines the procedures for interfacing with physical network hardware such as Ethernet devices. Its primary function is to manage the direct connections between different network nodes and handle how data is physically transmitted over the network.
I would venture D
I took the exam twice, and these questions were not even in the ballpark for the GSEC. A moderator may not show my comment here. These questions are ancient.
The TCP/IP model does not have universally agreed upon layer names, but the functions of each layer are well-defined. Looking at the options: A) End-to-end data delivery is a function of the Transport layer. B) Routing of packets is a function of the Internet layer. C) IP addressing and encryption happen at multiple layers, but are not specifically functions of the bottom layer. D) Interfacing with actual physical network hardware like Ethernet is a function of the bottom Network Access or Link layer. So the correct option is D
Answer C
