Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 318

Which encapsulation supports an interface that is configured for an EVN trunk?

Answer options

• A. 802.1Q
• B. ISL
• C. PPP
• D. Frame Relay
• E. MPLS
• F. HDLC A

Correct answer:

Explanation

The correct answer is A. 802.1Q, as it is the standard encapsulation method used for VLAN tagging and is required for EVN trunks. ISL (B) is a Cisco proprietary protocol that is not as commonly used and does not support EVN. The other options (C, D, E, F) are not relevant for VLAN trunking in the context of EVN.
