Your customer is a large hotel that would like to use a single VLAN per floor and isolate each room's wired network port from the others. Which CX switch feature should you recommend for the simplest solution?
Correct Answer:
C
To isolate wired ports on the same VLAN on a large scale (such as hotel rooms) but allow communication within the same VLAN for common areas, Private VLANs (PVLANs) are recommended. PVLANs allow segmentation within a single VLAN by dividing it into primary and secondary VLANs, controlling communication between ports.
VPN and VXLAN are overlay technologies for different purposes.
UBT (User-Based Tunneling) is related to wireless user segmentation, not wired port isolation.
Therefore, PVLANs provide the simplest and most effective solution to isolate room ports within a single VLAN.
