Zorluk: KolayVLAN Configuration and 802.1Q Trunking

A network technician is configuring an 802.1Q trunk link between two switches to carry traffic across multiple VLANs. Which VLAN designation is assigned to handle untagged frame traffic traversing this trunk by default?

  1. Native VLANCevap
  2. B
    Access VLAN
  3. C
    Voice VLAN
  4. D
    Management VLAN

Cevap

Native VLAN
In 802.1Q trunking, the native VLAN is explicitly designated to forward untagged traffic received on or sent across a trunk port without inserting an 802.1Q VLAN tag.

Adım Adım Çözüm

1
Identify the operation of 802.1Q trunking.
802.1Q trunking adds a 4-byte header tag to frames belonging to specific VLANs to distinguish them across switches.
Trunk links carry traffic for multiple VLANs over a single physical link.
2
Determine how untagged frames are handled on a trunk link.
Untagged frames do not contain an 802.1Q header tag and are mapped directly to the designated native VLAN.
By default, 802.1Q encapsulation defines a native VLAN to support backward compatibility and untagged legacy traffic.
