Explanation

This question involves Q-in-Q (IEEE 802.1ad) double-tagging / Provider Bridge configuration. PE1 acts as a service-VLAN (S-VLAN) push point: it adds S-VLAN 10 for CE1 OAM traffic and S-VLAN 20 for CE2 data traffic before forwarding frames toward PE2 across the provider network. PE2's role is to receive these double-tagged frames and pop (remove) the outer S-VLAN tag, then forward the inner C-VLAN traffic to the correct downstream interface. The correct configuration for PE2 must be applied on the interface facing the correct downstream CE/server segment (Interface Ge0/1 in option D). The configuration must include service instance mapping that matches incoming S-VLAN tags (S-VLAN 10 → VLAN 100 for the OAM server, S-VLAN 20 for the data gateway) and rewrite rules to pop or translate those outer tags appropriately. Options A, B, and C either use the wrong interface (Ge0/0 faces the wrong segment) or apply an incorrect VLAN mapping that does not satisfy both the OAM and data traffic forwarding requirements simultaneously.
