A. B. C. D.D.
The command that should be used to configure traffic for a VLAN that is untagged by the switch as it crosses a trunk link is the "switchport trunk native vlan" command.
Explanation: A trunk link is a link that carries traffic for multiple VLANs between switches. In order for traffic to be properly handled, the VLAN ID needs to be identified and tagged on the traffic as it crosses the trunk link. However, there may be situations where some VLANs do not need to be tagged, such as when the traffic is being sent to a device that does not support VLAN tagging.
In this scenario, the "switchport trunk native vlan" command is used to configure the native VLAN for the trunk link. The native VLAN is the VLAN that is not tagged as it crosses the trunk link. By default, the native VLAN is VLAN 1.
So in this case, the engineer needs to configure the native VLAN for the trunk link to the desired VLAN ID, which is VLAN 10 according to the answer choices. Therefore, the correct answer is D. "switchport trunk native vlan 10"
