Difficulty: EasyNetwork Components Roles and Functions

A network technician needs to connect multiple endpoint devices in a local office environment. The operational requirement dictates that each connected device must reside in its own dedicated collision domain while all devices remain within a single, shared broadcast domain for local communication. Which network component fulfills this primary role?

  1. Layer 2 switchAnswer
  2. B
    Network router
  3. C
    Ethernet hub
  4. D
    Type 1 hypervisor

Answer

Layer 2 switch
A Layer 2 switch provides microsegmentation, placing every connected port into its own individual collision domain. However, unless VLANs are configured, all switch ports reside within a single broadcast domain, allowing broadcast frames to reach all connected endpoints.

Step-by-Step Solution

1
Identify collision domain capabilities
Each microsegmented port on a Layer 2 switch forms its own distinct collision domain.
Switches buffer frames per port and support full-duplex operation, eliminating collisions between endpoints.
2
Identify broadcast domain capabilities
By default, all ports on an unconfigured Layer 2 switch belong to the same broadcast domain.
Switches flood Layer 2 broadcast frames out all active ports except the receiving port within the same VLAN.
