Zorluk: KolayNetwork Components Roles and Functions

A network administrator needs to segment a local network into distinct broadcast domains to prevent excessive broadcast traffic from degrading performance. Which network device natively creates a separate broadcast domain on each of its physical interfaces?

  1. RouterCevap
  2. B
    Unmanaged Layer 2 Switch
  3. C
    Ethernet Hub
  4. D
    Type 2 Hypervisor

Cevap

The router is the network component that natively creates separate broadcast domains on each of its physical interfaces.
Routers operate at Layer 3 of the OSI model and separate networks into distinct IP subnets. Because routers do not forward Layer 2 broadcast packets by default, each physical interface on a router forms a separate broadcast domain.

Adım Adım Çözüm

1
Identify the OSI layer boundary required to block Layer 2 broadcast traffic.
Layer 3 (Network Layer) boundaries prevent Layer 2 broadcast frames (such as MAC address FF:FF:FF:FF:FF:FF) from passing between connected networks.
Broadcast traffic is confined to its local subnet unless specifically routed or relayed by design.
2
Determine which component performs default Layer 3 boundary isolation.
Routers connect independent Layer 3 networks and terminate Layer 2 broadcast domains on each interface.
Each physical interface of a router is assigned to a distinct IP subnet and acts as an independent broadcast domain boundary.
