The correct statements are that EVPN route type 2 advertises MAC and IP addresses, route type 3 handles inclusive multicast, and VXLAN encapsulation uses a UDP header. These three options are correct because EVPN-VXLAN relies on BGP EVPN route types to distribute reachability information across the overlay, with type 2 carrying host MAC and IP bindings, type 3 signaling multicast group membership for BUM traffic, and VXLAN encapsulating Ethernet frames in UDP over a Layer 3 underlay. On the Cisco SPCOR 350-501 exam, this topic tests your understanding of how control-plane learning (via EVPN route types) differs from traditional data-plane flooding, and a common trap is assuming VXLAN always requires ingress replication for BUM traffic—it can also use multicast or ARP suppression. Another trap is forgetting that VXLAN is a Layer 2 overlay over a Layer 3 underlay, not the reverse. Memory tip: think “2 for MAC/IP, 3 for multicast, UDP for the tunnel.”
350-501 Services Practice Question
This 350-501 practice question tests your understanding of services. 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. 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.
Which THREE of the following are correct statements about EVPN-VXLAN in a data center fabric? (Select three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
EVPN route type 3 is used for BUM traffic forwarding.
Options A, B, and D are correct. EVPN-VXLAN uses BGP EVPN route type 2 for MAC/IP advertisement, route type 3 for inclusive multicast, and VXLAN encapsulation uses a UDP header. Option C is wrong: VXLAN uses multicast or BGP EVPN but not necessarily ingress replication for BUM traffic; it can use multicast or ARP suppression. Option E is wrong: VXLAN is a Layer 2 overlay over a Layer 3 underlay.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
EVPN route type 3 is used for BUM traffic forwarding.
Why this is correct
Route type 3 is the inclusive multicast route.

Read the scenario before looking for a memorised answer.
✓
VXLAN encapsulation adds a 50-byte outer header (14 Ethernet + 20 IP + 8 UDP + 8 VXLAN).
Why this is correct
VXLAN adds 50 bytes (or 54 if VLAN tag considered).

✓
EVPN route type 2 is used to advertise MAC and IP addresses.
Why this is correct
Route type 2 carries MAC and IP binding.
Related concept
Read the scenario before looking for a memorised answer.
✗
VXLAN is a Layer 3 overlay that requires an IGP in the overlay.
Why it's wrong here
VXLAN is a Layer 2 overlay; no IGP in overlay.
✗
VXLAN always requires IP multicast in the underlay for BUM traffic.
Why it's wrong here
BUM can be handled by ingress replication or multicast.
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 350-501 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.
