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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An administrator needs to open a Microsoft 365 support request because all users are experiencing intermittent service outages for Exchange Online. Before contacting support, which two pieces of information should the administrator have ready to ensure efficient troubleshooting? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Tenant ID (or Microsoft 365 tenant domain name)
The Tenant ID (or Microsoft 365 tenant domain name) is required by Microsoft Support to uniquely identify your tenant in their systems, enabling them to pull up your service configuration, subscription details, and relevant health data. This identifier is essential for routing the support request to the correct engineering team and for correlating the issue with backend telemetry.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

While helpful, the number of affected users is not mandatory for the initial support ticket; it can be provided later.
✓
Detailed description of the problem and troubleshooting steps attempted
Why this is correct
A clear problem description helps support understand the issue and reduces back-and-forth.

✗
Network bandwidth graph from the past 24 hours
Why it's wrong here
Network details are usually provided if the problem is determined to be network-related, but not essential at first.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'nice-to-have' diagnostic data (like the number of affected users or network graphs) with the mandatory identification and problem description that Microsoft Support requires to initiate a case.
Detailed technical explanation
How to think about this question
The Tenant ID is a globally unique GUID (e.g., 12345678-1234-1234-1234-123456789abc) that Microsoft uses to index all tenant resources in Azure Active Directory and Exchange Online. When opening a support case, providing this ID allows the support engineer to immediately access tenant-specific service health dashboards, audit logs, and throttling policies without requiring additional authentication steps.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
