Which network virtualization technologies can be used with an Ethernet VPN (EVPN) deployment in NSX-T Data Center? (Choose two.)
A. Virtual Extensible Local Area Network (VXLAN)
B. Multiprotocol Border Gateway Protocol (MP-BGP)
C. Open Shortest Path First (OSPF)
D. Multiprotocol Label Switching (MPLS)
E. Virtual Routing and Forwarding (VRF)
VXLAN and MPLS are encapsulcation type.
MP-BGP plus VRF are technocaligy that make up the EVPN.
Therefore B & E are correct answer.
E and B use A. Since only two can be chosen the best answers are E & B.

L3 Ethernet VPN (EVPN): Provides the northbound connectivity option to advertise all VRFs on an NSX Tier-0 gateway through MP-BGP EVPN AFI (Route Type 5) to a Provider Edge and maintain the isolation on the data plane using VXLAN encapsulation by using one VNI per VRF.
Correcting myself. The most likely to be true answers should be A and E.
In EVPN with NSX-t you can find mpls, vxlan, mp-bgp and VRF litle. So OSPF is not one of the answer. About the remaining. MPLS is a protocol based on labels, mp-BGP a protocol extension for BGP . The key word is virtualization techinques.. so VRF(E) is one the answer and the other by discard vxlan switch is some kind of virtualization(A).
However from my point of view htis question is ambiguous. For example VRF should be VRF-litle to be 100% accurate and mpls could considered as data-path virtualization.
