CCSP · Question #33
A virtual network interface card (NIC) exists at layer __________ of the OSI model.
The correct answer is A. 2. A virtual network interface card (NIC), like its physical counterpart, operates at Layer 2 (Data Link Layer) of the OSI model, responsible for media access control (MAC) addressing and frame transmission.

Why each option
A virtual network interface card (NIC), like its physical counterpart, operates at Layer 2 (Data Link Layer) of the OSI model, responsible for media access control (MAC) addressing and frame transmission.
A virtual network interface card (NIC) functions at Layer 2, the Data Link Layer, of the OSI model. At this layer, NICs are responsible for framing data into frames, handling Media Access Control (MAC) addressing, and enabling communication between devices on the same local network segment.
Layer 4 is the Transport Layer, responsible for end-to-end communication, segmentation, and reassembly of data (e.g., TCP/UDP), which is above the function of a NIC.
Layer 6 is the Presentation Layer, responsible for data formatting, encryption, and compression, which is handled by software above the data link layer.
The OSI model has seven layers, so Layer 8 does not exist as a standard layer within the model.
