Zorluk: KolayVLAN Configuration and 802.1Q Trunking

A network technician needs to configure a switch interface that connects to an upstream distribution switch. The link must carry traffic for multiple VLANs concurrently over the single physical link using IEEE 802.1Q tagging. Which interface configuration command must be applied to achieve this functionality?

  1. switchport mode trunkCevap
  2. B
    switchport mode access
  3. C
    switchport mode dynamic auto
  4. D
    spanning-tree portfast

Cevap

The interface must be configured using `switchport mode trunk` to carry traffic for multiple VLANs over a single physical link.
The command `switchport mode trunk` configures an Ethernet interface to operate as an 802.1Q trunk link, allowing frames from multiple VLANs to be tagged and multiplexed across a single physical link between network devices.

Adım Adım Çözüm

1
Identify the requirement for cross-switch link multi-VLAN traffic transport
The link must multiplex frames from multiple broadcast domains using IEEE 802.1Q header tags.
Standard access ports strips or drops tags and belong to only one VLAN.
2
Select the appropriate switchport interface command
Applying `switchport mode trunk` explicitly sets the operational mode to trunking.
Trunk ports inspect 802.1Q tags and pass traffic for all allowed VLANs across the switch interconnect.
