A. B. C. D.A
The correct answer is D. 2 through 1005.
By default, a Cisco switch can support up to 1005 VLANs, numbered 2 through 1005. VLAN 1 is the default VLAN for all Cisco switches, and it cannot be deleted or modified. VLANs 1002 through 1005 are reserved for Token Ring and FDDI VLANs and are not usable for Ethernet VLANs.
So, VLANs 2 through 1001 are available for Ethernet VLANs, and they can be added, modified, and removed on a Cisco switch by default. However, VLANs 1002 through 1005 cannot be deleted or modified.
Therefore, option D (2 through 1005) is the correct answer.
