Which encapsulation supports an interface that is configured for an EVN trunk?
A . 802.1Q
B . ISL
C . PPP
D . Frame Relay
E . MPLS
F . HDLC

Answer: A

Explanation:

Restrictions for EVN An EVN trunk is allowed on any interface that supports 802.1q encapsulation, such as FastEthernet, Gigabit Ethernet, and port channels.

A single IP infrastructure can be virtualized to provide up to 32 virtual networks end-to-end. If an EVN trunk is configured on an interface, you cannot configure VRF-Lite on the same interface. OSPFv3 is not supported; OSPFv2 is supported.
