Quick Answer
The answer is Route Type 1 (Ethernet Auto-Discovery) because in an EVPN-VPWS deployment, this route type is responsible for advertising MAC address reachability information, specifically carrying the MAC address for split-horizon filtering and per-EVI/ per-ES AD routes. While Route Type 2 handles MAC/IP advertisement in EVPN multipoint scenarios, VPWS is a point-to-point service where MAC learning is not typically required; instead, Route Type 1 embeds the MAC address to enable proper forwarding and prevent loops. On the Cisco SPCOR 350-501 exam, this concept tests your understanding of how EVPN-VPWS differs from EVPN-MPLS, and a common trap is confusing Route Type 2 as the primary MAC advertiser in VPWS. Remember the memory tip: "VPWS is a point-to-point wire, so Route Type 1 is the one that carries the MAC for the split-horizon stack."
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.
A service provider is deploying EVPN-VPWS to replace legacy pseudowire connections for point-to-point Layer 2 services. They notice that MAC addresses learned from a CE device are not properly advertised to the remote PE. Which EVPN route type is responsible for advertising MAC address reachability information in a VPWS scenario?
Route Type 1 (Ethernet Auto-Discovery)
Ethernet AD routes include MAC address information for split-horizon.
Route Type 2 (MAC/IP Advertisement)
Why wrong: Route Type 2 is for MAC/IP advertisement but not mandatory for VPWS.
Route Type 5 (IP Prefix)
Why wrong: Route Type 5 is for IP prefix advertisement, not MAC.
Route Type 3 (Inclusive Multicast)
Why wrong: Route Type 3 is used for multicast, not unicast MAC.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Route Type 1 (Ethernet Auto-Discovery)
Option A is correct because Route Type 1 (Ethernet Auto-Discovery) is used for VPWS per-EVI and per-ES AD routes, which include MAC mobility information. Route Type 2 is for MAC/IP advertisement, but in VPWS, MAC learning is not required typically; however, Route Type 1 carries the MAC address for split-horizon filtering. Option B (RT-2) is for MAC/IP but not the primary for VPWS. Option C (RT-3) is for inclusive multicast. Option D (RT-5) is for IP prefix.
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.

Why it's wrong here
Route Type 2 is for MAC/IP advertisement but not mandatory for VPWS.
Route Type 5 (IP Prefix)
Why it's wrong here

Route Type 3 is used for multicast, not unicast MAC.
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.
