Zorluk: KolaySwitching Concepts and VLANs

An network administrator is deploying Virtual Local Area Networks (VLANs) on a newly installed Layer 2 enterprise switch. Which of the following statements accurately describe key operational characteristics of VLANs? (Select TWO).

  1. VLANs divide a single physical switch into multiple separate broadcast domains.Cevap
  2. Hosts assigned to different VLANs on the same physical switch require a Layer 3 routing function to communicate.Cevap
  3. C
    Hosts assigned to different VLANs on the same switch can communicate directly at Layer 2 without a gateway.
  4. D
    VLAN tagging operates at Layer 4 of the OSI model to segment TCP connection ports.
  5. E
    Configuring VLANs automatically disables Spanning Tree Protocol (STP) on all switch ports.

Cevap

VLANs divide a single physical switch into multiple separate broadcast domains, and hosts assigned to different VLANs on the same switch require a Layer 3 routing function to communicate.
VLANs logically partition a physical Layer 2 switch into independent broadcast domains. Because each VLAN is isolated at Layer 2, any communication between hosts located on different VLANs requires inter-VLAN routing performed by a Layer 3 device.

Adım Adım Çözüm

1
Analyze Layer 2 segmentation properties of VLANs
Creating VLANs breaks a physical switch into distinct logical segments, where each segment acts as its own independent broadcast domain.
Broadcast traffic generated on one VLAN is restricted solely to ports assigned to that specific VLAN.
2
Determine requirements for inter-VLAN communication
Traffic destined for a host in another VLAN must pass through a Layer 3 device (such as a router or Layer 3 switch).
Layer 2 switches do not forward frames between different broadcast domains without IP routing capabilities.
