You are implementing HPE Aruba Networking CX switches in a hotel environment.
Which feature would allow you to use a single subnet for the wired guests, allowing them to utilize only default gateway services and communicate with each other in a conference room but not elsewhere?
A. By assigning the guest users in the conference room to an isolated VLAN and the gateway to a primary VLA
B. By assigning the guest users in the conference room to a community VLAN and the gateway to a primary VLA
C. By assigning the guest users in the conference room to a primary VLAN and the gateway to an isolated VLA
D. By assigning the guest users in the conference room to an isolated VLAN and the gateway to a community VLA
Explanation:
In a hotel environment where a single subnet is used for wired guests, but guest devices in a conference room need to communicate with each other (and with the default gateway), while remaining isolated from other guests elsewhere, Community VLANs are appropriate.
Community VLANs allow hosts within the same VLAN community to communicate with each other and the default gateway but are isolated from hosts in other communities.
Isolated VLANs block communication between ports and only allow communication to the gateway.
Therefore, assigning conference room guests to a community VLAN and the gateway to a primary VLAN allows the desired communication model.
