- A
Wireless clients are assigned to the same virtual network (VN) as wired clients for consistent policy.
Correct because SD-Access unifies wired and wireless policy by placing both types of endpoints into the same VN.
- B
The wireless LAN controller in SD-Access must be a dedicated fabric role separate from the fabric edge.
Why wrong: Incorrect because the WLC can be integrated as a fabric edge or border node; there is no separate dedicated role.
- C
CAPWAP tunnels are used between the access point and the fabric edge for data traffic.
Why wrong: Incorrect because CAPWAP is used only between the AP and the WLC in the underlay; the fabric edge uses VXLAN for data traffic.
- D
The fabric uses a separate wireless overlay network for wireless traffic.
Why wrong: Incorrect because SD-Access uses a single VXLAN-based fabric overlay for both wired and wireless traffic.
- E
The access point encapsulates wireless traffic directly into VXLAN when the WLC is fabric-enabled.
Correct because when the WLC is fabric-enabled, the AP can encapsulate wireless client traffic directly into VXLAN, reducing overhead.
Quick Answer
The correct answer is that the access point does not encapsulate wireless traffic directly into VXLAN; instead, the fabric-enabled wireless controller (WLC) handles VXLAN encapsulation to the fabric edge. This is because in Cisco SD-Access wireless integration, the CAPWAP tunnel between the AP and WLC operates only in the underlay, while the fabric data plane uses VXLAN to map wireless clients to the same virtual network as wired clients, ensuring consistent policy enforcement. On the ENCOR 350-401 exam, this question tests your understanding of how the SD-Access fabric unifies wired and wireless traffic without a separate overlay, often trapping candidates who assume the AP performs VXLAN encapsulation directly. A common memory tip is: “AP talks CAPWAP, WLC talks VXLAN”—the WLC acts as the fabric edge or border, not the AP, so the VXLAN tunnel originates from the WLC, not the access point.
CCNP SD-Access Architecture Practice Question
This 350-401 practice question tests your understanding of sd-access architecture. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

Correct answer & explanation
Wireless clients are assigned to the same virtual network (VN) as wired clients for consistent policy.
In SD-Access, wireless clients are mapped to the same virtual network (VN) as wired clients, enabling consistent policy. The wireless controller (WLC) can be deployed as a fabric edge or border, not as a separate dedicated role. The CAPWAP tunnel is only used between the AP and the WLC in the underlay; once the WLC is fabric-enabled, it uses VXLAN to the fabric edge. The fabric does not require a separate wireless overlay; it uses the same VXLAN data plane. The AP does not encapsulate traffic directly into VXLAN; that is done by the fabric edge or the WLC.
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.
