Zorluk: KolayOSI Model Layers and Functions

A network technician is installing an unmanaged network switch to connect multiple client computers within a single office subnet. At which layer of the Open Systems Interconnection (OSI) model does this device primarily operate to forward Ethernet frames using MAC addresses?

  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) of the OSI model is responsible for node-to-node data transfer across a shared physical network segment. Standard switches inspect destination MAC addresses within incoming Ethernet frames to determine which port should receive the data.

Adım Adım Çözüm

1
Identify the primary addressing mechanism and PDU mentioned in the scenario
The device forwards Ethernet frames based on Media Access Control (MAC) addresses.
MAC addresses are hardware-level identifiers burned into network interface cards.
2
Map MAC address frame switching to the corresponding OSI model layer
Layer 2 is designated as the Data Link layer.
Standard network switches operate at Layer 2 to inspect frame header MAC addresses and deliver frames to the correct physical port.
