A network technician installs a standard Layer 2 Ethernet switch to connect multiple client computers in an office network. What is the primary operational function of this device?
- Forwarding Ethernet frames based on destination MAC addresses while separating collision domains per portCevap
- BForwarding IPv4 packets based on destination IP addresses while breaking up broadcast domains on every port
- CHosting and managing virtual machine instances directly on bare-metal hardware as a hypervisor
- DGathering neighboring device hardware details using Layer 3 routing protocol hello packets
Cevap
The primary operational function of a Layer 2 switch is forwarding Ethernet frames using MAC addresses and placing each switch port into its own independent collision domain.
A standard Layer 2 switch learns source MAC addresses and builds a MAC address table to forward incoming frames to their intended destination ports. Each physical port on the switch acts as an isolated collision domain, preventing frame collisions.
