Quick Answer
The answer is the l2vpn evpn address family. This is correct because EVPN with VXLAN encapsulation relies on BGP as the control plane to distribute MAC addresses and VTEP reachability, and the l2vpn evpn address family is specifically designed to carry EVPN routes, including Type-2 (MAC/IP) and Type-3 (IMET) routes, enabling efficient MAC/VTEP learning across a data center interconnect. On the Cisco SPCOR 350-501 exam, this question tests your ability to distinguish the correct BGP address family for modern EVPN deployments versus legacy options like vpnv4 for L3VPNs or l2vpn vpls-vpws for older VPLS solutions—a common trap is confusing these with the EVPN-specific address family. A helpful memory tip: think “EVPN = l2vpn evpn” as the two-layer VPN that bridges Layer 2 over Layer 3, and remember that the “evpn” keyword in the address family name directly signals its purpose for MAC/VTEP learning.
This 350-501 practice question tests your understanding of architecture. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An SP is deploying EVPN with VXLAN encapsulation in a data center interconnect. The design requires that the control plane for MAC/VTEP learning is based on BGP. Which BGP address family must be configured?
l2vpn evpn
The l2vpn evpn address family is used for EVPN control plane with BGP.
l2vpn vpls-vpws
Why wrong: This is for VPLS, not EVPN.
vpnv4
Why wrong: vpnv4 is for MPLS L3VPN, not EVPN control plane.
ipv4 unicast
Why wrong: IPv4 unicast is for standard IP routing, not EVPN MAC/VTEP learning.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
l2vpn evpn
The l2vpn evpn address family is used for EVPN. Option A is vpnv4 for L3VPN, Option B is l2vpn vpls-vpws (legacy), Option C is ipv4 unicast. Thus D is correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
l2vpn evpn
Why this is correct
The l2vpn evpn address family is used for EVPN control plane with BGP.

l2vpn vpls-vpws
Why it's wrong here
This is for VPLS, not EVPN.
vpnv4
Why it's wrong here
vpnv4 is for MPLS L3VPN, not EVPN control plane.
ipv4 unicast
Why it's wrong here
IPv4 unicast is for standard IP routing, not EVPN MAC/VTEP learning.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 350-501 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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An ISP is deploying EVPN-VXLAN for its data center interconnect. Which statement about control-plane learning is correct?
hardWhy C: Option A is correct because EVPN uses BGP as the control plane to advertise MAC/VPN routes. Option B is wrong because IRB is for integrated routing and bridging, not control-plane learning. Option C is wrong because MP-BGP is used, not OSPF. Option D is wrong because VXLAN is data-plane encapsulation.
