Which two statements are correct about L2PT? (Choose two.)
A.
L2PT requires 802.1Q tunneling enablement to effectively tunnel L2 protocols.
B.
802.1Q tunnels all L2 protocols by default.
C.
L2PT encapsulates L2 PDUs by enabling the ingress switch to rewrite the PDUs’ source MAC
addresses before forwarding them onto the service provider network.
D.
You cannot enable L2PT and VLAN translation on the same VLAN.

These are correct
A – You configure L2PT at the [edit vlans vlan-name dot1q-tunneling] hierarchy level, meaning Q-in-Q tunneling is (and must be) enabled.
D – Note: VLAN translation is not compatible with L2PT. (You configure VLAN translation with the mapping swap statement at the [edit vlans interface] hierarchy level.)
=============
C – proven wrong here ===>
L2PT encapsulates Layer 2 PDUs by enabling the ingress provider edge (PE) device to rewrite the PDUs’ destination media access control (DMAC) addresses before forwarding them onto the service provider network.
