Question 822 of 2,015

SD-WAN Architecture →mediumDrag & DropObjective-mapped

Quick Answer

The correct final step in the SD-WAN zero-touch provisioning flow order is that the device downloads its full configuration and joins the fabric. This sequence is critical because ZTP is designed to automate the entire onboarding process without manual intervention: the device first obtains an IP address via DHCP, then contacts the cloud portal to authenticate and receive the list of vManage controllers, after which it establishes a secure DTLS connection to vManage, downloads its complete configuration, and finally joins the control plane to become part of the fabric. On the ENCOR 350-401 exam, this drag-and-drop question tests your understanding of the precise order of ZTP events, with a common trap being the misplacement of the DTLS tunnel establishment before the vManage list retrieval. A useful memory tip is to think of the acronym "D-C-D-J" for DHCP, Cloud portal, DTLS, and Join—remember that the full configuration download must occur before the device can join the fabric.

350-401 SD-WAN Architecture Practice Question

This 350-401 practice question tests your understanding of sd-wan 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.

Drag and drop the steps of SD-WAN zero-touch provisioning (ZTP) flow into the correct order, from first to last.

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Device boots and obtains IP via DHCP

The ZTP flow begins with the device obtaining an IP address via DHCP, then contacting the cloud portal to authenticate and receive the vManage list, followed by establishing a DTLS connection to vManage, downloading the full configuration, and finally joining the 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.

What to study next

Got this wrong? Here's your next step.

Identify which 350-401 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.

✓ A.Device boots and obtains IP via DHCP
✓ B.Device resolves vManage hostname via DNS
✓ C.Device establishes DTLS tunnel to vManage
✓ D.Device downloads full configuration from vManage
✓ E.Device applies configuration and becomes operational

Why A: ZTP starts with the device contacting the DHCP server for an IP address, then resolving the vManage hostname via DNS, establishing a DTLS connection to vManage, downloading the full configuration, and finally applying the configuration to become operational.
