Zorluk: KolayOSI Model Layers and Functions

A network technician is monitoring traffic on a local network segment and observes data organized into frames containing physical MAC addresses for node-to-node delivery. At which layer of the OSI model does this hardware addressing and framing occur?

  1. Data Link layerCevap
  2. B
    Network layer
  3. C
    Transport layer
  4. D
    Physical layer

Cevap

Data Link layer
The Data Link layer (Layer 2) is specifically responsible for node-to-node transfer on the same local network segment. It packages network layer data into frames and uses hardware (MAC) addresses to direct traffic between physical network interfaces.

Adım Adım Çözüm

1
Identify the Protocol Data Unit (PDU) and addressing type described in the scenario.
The scenario mentions data organized into 'frames' using physical 'MAC addresses'.
Different OSI layers use specific PDUs and address types.
2
Map frames and MAC addresses to the corresponding OSI layer.
Frames and MAC (Media Access Control) addressing operate specifically at Layer 2.
Layer 2 (Data Link layer) encapsulates network layer packets into frames for transmission across a local physical segment using MAC addresses.
