Explanation
To pass traffic from multiple VLANs and set a custom native VLAN, an interface must be configured as a trunk port.
Common mistakes.
- B. This option is identical to A, but it's a duplicate and not the designated correct answer.
- C. The
switchport mode dynamiccommand relies on DTP negotiation, which may not always result in a trunk link or allow for consistent native VLAN configuration across different switches. - D. The
switchport mode accesscommand configures an interface to carry traffic for only a single VLAN, which fails the requirement to pass traffic from two different VLANs.
Concept tested. Trunk port configuration with native VLAN
