MS-102 Deploy and manage a Microsoft 365 tenant Practice Question
This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant. 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.
Which TWO actions are required to configure a custom domain for your Microsoft 365 tenant?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add the domain name in the Microsoft 365 admin center.
Option D is correct because adding the custom domain name in the Microsoft 365 admin center is the first step to register the domain with the tenant. Option E is correct because Microsoft requires you to prove ownership of the domain by adding a specific TXT record (or sometimes a CNAME or MX record) to the public DNS zone; this verification step ensures only the domain owner can configure it for the tenant.
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.
✗
Add an SPF TXT record in the public DNS zone.
Why it's wrong here
SPF is for email authentication, not domain verification.
✗
Add a CNAME record for autodiscover.
Why it's wrong here
Autodiscover CNAME is for Exchange connectivity, not verification.
✗
Add an MX record in the public DNS zone.
Why it's wrong here
MX record is for mail routing, not domain verification.
✓
Add the domain name in the Microsoft 365 admin center.
Why this is correct
You must first register the domain in the admin center.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse optional service-specific DNS records (like SPF, MX, or autodiscover CNAME) with the mandatory domain ownership verification record, leading them to select A, B, or C instead of the correct verification TXT record option.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft 365 uses the Domain Ownership Verification process defined in RFC 8555 (ACME-like) but adapted for its own portal; the TXT record must contain a unique verification string generated by the admin center, and Microsoft’s DNS servers periodically query the public DNS to confirm the record exists. A subtle behavior is that the verification TXT record can be removed after successful verification, but many administrators leave it in place to avoid re-verification if the domain is re-added. In real-world scenarios, if you skip the verification step and only add the domain name, Microsoft 365 will not allow you to assign user accounts or enable services for that domain.
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.
TExam Day Tips
→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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
