Quick Answer
The answer is EVPN, which matches to the description of a Layer 2 VPN control plane using BGP for MAC and VXLAN distribution. This is correct because EVPN (Ethernet VPN) operates as a modern control plane for Layer 2 services, using BGP to advertise MAC addresses and integrate with VXLAN for overlay tunneling, whereas L3VPN handles IP routing at Layer 3 with VRF, and both L2VPN and VPLS are data-plane-driven Layer 2 solutions—VPLS being multipoint and VPWS point-to-point. On the ENCOR 350-401 exam, this drag-and-drop question tests your ability to distinguish MPLS VPN types by their operational layer and control plane mechanisms; a common trap is confusing VPLS with EVPN since both provide multipoint L2 connectivity, but remember that VPLS uses traditional LDP or BGP signaling for pseudowires while EVPN uses BGP as a modern control plane for MAC distribution. A helpful memory tip: think “E” for EVPN = “E” for Ethernet control plane, while VPLS is just “V” for virtual private LAN service without a separate control plane.
350-401 MPLS Practice Question
This 350-401 practice question tests your understanding of mpls. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below.

Correct answer & explanation
✓
L3VPN: Operates at Layer 3 using IP routing and VRF
L3VPN uses IP routing (Layer 3) and VRF, L2VPN emulates Layer 2 services like Ethernet, VPLS is a multipoint L2VPN, VPWS is a point-to-point L2VPN, and EVPN is a modern L2VPN control plane.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 350-401 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
