QuestionQ2

Layer 2 Switching and VLANs

Which two statements are true about configuring VLANs?

Choose two
  • A You must assign an IRB interface to each VLAN.
  • B You must assign a VLAN name or ID and a Layer 2 interface to the VLAN.
  • C You can assign one or more VLANs to a trunk mode interface.
  • D You can assign one or more VLANs to an access mode interface.
Explanation

A VLAN is defined with a VLAN name or identifier and Layer 2 interface membership. A trunk-mode interface carries traffic for multiple VLANs, while an access-mode interface is limited to one VLAN. An IRB interface is only needed to provide Layer 3 routing for a VLAN.
