Which two statements about Metro Ethernet services are true? (Choose two.)
A.
EPL is a point-to-point service from one customer site to another across an MPLS backbone.
B.
EVPL is a multipoint service that emulates a LAN over an MPLS backbone.
C.
EPLAN is a multipoint service that emulates a LAN over an MPLS backbone.
D.
EVPL is a point-to-point service from one customer site to another across an MPLS backbone.
E.
ELAN is a point-to-point service from one customer site to another across an MPLS backbone.
F.
EVPL is a multipoint service with a root node that is suitable for multicast services.
A & B are correct.
E-Lines (EPL and EVPL) must be point-to-point.
E-LANs (EPLAN and EVPLAN) must be multi-point to multi-point.
A, C & D are all correct.

B is wrong as EVPL is a p2p service.
I think A C D are valid
However, D is more correct than C. EPLAN can use VPLS over an MPLS core OR an Ethernet core. EVPL MUST use an MPLS core. So, A and C are the correct answers. Please see the following:

Sorry, A and D are the correct answers, since D is more correct than C.
