SSCP · Question #1102
Which form of media is handled at the Physical Layer (Layer 1) of the OSI Reference Model?
The correct answer is E. Ethernet. The Physical Layer (Layer 1) of the OSI model deals with the physical transmission of raw bit streams over a physical medium, and Ethernet defines the physical and data link layers for local area networks.

Why each option
The Physical Layer (Layer 1) of the OSI model deals with the physical transmission of raw bit streams over a physical medium, and Ethernet defines the physical and data link layers for local area networks.
MAC (Media Access Control) addresses and protocols operate at the Data Link Layer (Layer 2) for device addressing and frame transmission.
L2TP (Layer 2 Tunneling Protocol) operates at the Data Link Layer (Layer 2), encapsulating other protocols for secure tunneling.
SSL (Secure Sockets Layer) and TLS operate at the Presentation Layer (Layer 6) and Session Layer (Layer 5) of the OSI model, providing secure communication for application-layer protocols.
HTTP (Hypertext Transfer Protocol) operates at the Application Layer (Layer 7) of the OSI model, facilitating web communication.
Ethernet, specifically its physical aspects like twisted-pair cables, fiber optics, and electrical signals, operates at the Physical Layer (Layer 1) of the OSI model, defining how bits are transmitted over a network medium.
