Which two statements about private VLANs are true? (Choose two.)
A.
Only one isolated VLAN can be mapped to a primary VLAN.
B.
Only one community VLAN can be mapped to a primary VLAN.
C.
Multiple isolated VLANs can be mapped to a primary VLAN.
D.
Multiple community VLANs can be mapped to a primary VLAN.
Only one isolated VLAN can be mapped to a primary VLAN–since the isolated VLAN itself is isolated, it makes no sense to have multiple isolated VLANs, as you should just be able to reuse the single isolated VLAN for hosts that you want to be in the ‘isolated’ state who can only talk to promiscuous ports (usually the DG).
1. You can configure only one isolated VLAN in a PVLAN
2 .You can configure multiple community VLANs in a PVLAN domain
Isolated VLANs—Ports within an isolated VLAN cannot communicate directly with each other at the Layer 2 level.
Community VLANs—Ports within a community VLAN can communicate with each other but cannot communicate with ports in other community VLANs or in any isolated VLANs at the Layer 2 level.
