EVPN is a VPN technology that can only provide layer 2 network interconnection.
The correct answer is B. FALSE. B (FALSE) is correct because EVPN (Ethernet VPN) is not limited to Layer 2 - it supports both Layer 2 (bridging/VLAN extension) and Layer 3 (IP routing/VRF) services within the same framework, making it a flexible multi-service VPN technology built on BGP. Why A (TRUE) is…

Explanation
B (FALSE) is correct because EVPN (Ethernet VPN) is not limited to Layer 2 - it supports both Layer 2 (bridging/VLAN extension) and Layer 3 (IP routing/VRF) services within the same framework, making it a flexible multi-service VPN technology built on BGP.
Why A (TRUE) is wrong: Saying EVPN is "only" Layer 2 ignores its Layer 3 capabilities, including symmetric IRB (Integrated Routing and Bridging) and prefix advertisement, which allow full IP routing between sites without a separate L3VPN solution.
Memory tip: Think of EVPN as "Everything VPN" - the "E" stands for Ethernet historically, but the technology evolved to handle both Ethernet (L2) and IP (L3) forwarding. If you remember that modern EVPN is often deployed in data centers for VXLAN overlays that carry both L2 and L3 traffic, you won't confuse it with a pure L2 technology.
