You configured a port on a Cisco Nexus 7000 switch as a trunk port. Which VLANs are allowed on the trunk port based on the port configuration in the exhibit?

B. Only Native VLAN 1 will be allowed.
C. VLANs 1 to 3967, and 4048 to 4094 are allowed.
D. VLANs 1 to 3900, and 4048 to 4094 are allowed.
E. VLANs 1 to 4094 are allowed.
Correct Answer: C
Explanation/Reference:
Explanation:
Sets the allowed VLANs for the trunk interface. The default is to allow all VLANs on the trunk interface: 1 to 3967 and 4048 to 4094. VLANs 3968 to 4047 are the default VLANs reserved for internal use by default; this group of VLANs is configurable. By default, all VLANs are allowed on all trunk interfaces.
You cannot add internally allocated VLANs as allowed VLANs on trunk ports. The system returns a message if you attempt to list an internally allocated VLAn as an allowed VLAN.
