Zorluk: KolaySwitching Concepts and VLANs

A network administrator configures separate VLANs for the Accounting and Marketing departments on the same physical Layer 2 switch. Which of the following best describes the primary operational benefit of this configuration?

  1. It divides the physical switch into distinct logical broadcast domains, isolating traffic between departments.Cevap
  2. B
    It allows devices in the Accounting department to communicate directly with devices in the Marketing department without requiring a routing device.
  3. C
    It converts Layer 2 Ethernet frames directly into Layer 3 IP packets at the switchport interface.
  4. D
    It configures the switch to select the connected switch with the highest numerical priority value as the Spanning Tree root bridge.

Cevap

It divides the physical switch into distinct logical broadcast domains, isolating traffic between departments.
The option describing broadcast domain segmentation is correct. Virtual LANs (VLANs) logically separate switch ports into discrete broadcast domains, isolating Layer 2 traffic between different groups or departments to enhance network performance and security.

Adım Adım Çözüm

1
Identify the primary function of Virtual Local Area Networks (VLANs) on a Layer 2 switch.
VLANs logically segment a single physical switch into separate broadcast domains.
By default, all ports on an unconfigured switch belong to a single broadcast domain. VLANs break up this single domain.
2
Analyze the impact on network traffic and departmental isolation.
Broadcast traffic sent by a host in one VLAN is contained strictly within that VLAN.
Containing broadcast traffic improves performance and security across different administrative departments.
