Wait, are we sure about D? I thought QinQ was more for enterprise setups.

I disagree with B, the service VLAN ID can differ from the user VLAN ID.

A is definitely true, all users on the same PON share the outer VLAN.

I vaguely remember QinQ being used for data services, so option D might be right, but I need to double-check how inner tags work for user identification.

I practiced a question similar to this, and I believe option C is correct since different VLANs can indeed map user data to different GEM ports.

I think option B sounds familiar, but I can't recall if the service VLAN ID always has to match the user VLAN ID when using a single tag.

I remember something about VLANs in FTTx, but I'm not sure if all users on the same PON port really share the same outer VLAN.

The last statement about QinQ being generally used for data services and inner tags identifying different users seems reasonable. I'll select that one.

I'm a bit unsure about the third statement regarding mapping user data into different GEM ports based on VLANs. I'll need to think that one through more.

The second statement about the service VLAN ID and user VLAN ID being the same when using a single tag is also making sense to me. I'll choose that one too.
