Zorluk: KolaySwitching Concepts and VLANs

An IT technician notices that excessive broadcast packets are reaching every workstation connected to a 48-port switch, leading to unwanted network overhead. The technician needs to divide the switch into smaller, isolated broadcast domains without adding physical hardware. Which switching feature should be implemented to achieve this goal?

  1. Virtual Local Area Networks (VLANs)Cevap
  2. B
    Spanning Tree Protocol (STP)
  3. C
    802.1Q Native VLAN tagging
  4. D
    Full-duplex link negotiation

Cevap

Virtual Local Area Networks (VLANs)
Virtual Local Area Networks (VLANs) allow network administrators to partition a single physical switch into multiple logical Layer 2 broadcast domains. Broadcast traffic sent by a device in one VLAN will only be forwarded to ports assigned to that same VLAN, effectively reducing broadcast overhead without requiring additional physical switch hardware.

Adım Adım Çözüm

1
Identify the primary network issue described in the scenario.
The physical switch forms a single large broadcast domain, causing broadcast traffic to reach all connected hosts.
By default, all switch ports reside in the same Layer 2 broadcast domain.
2
Determine the required switching mechanism to divide broadcast domains logically.
Configuring Virtual Local Area Networks (VLANs) isolates traffic between port groups on a single physical switch.
VLANs break a single physical switch into logical Layer 2 boundaries, containing broadcast traffic within each specific VLAN.
