The correct answer is the Tenant ID and the current service health status. The Tenant ID is a globally unique, immutable identifier that Microsoft Support uses to locate your specific tenant in their backend systems and verify administrative permissions, making it essential for any support request. The current service health status is equally critical because support engineers will immediately check the Microsoft 365 Service Health Dashboard to determine if your issue is a known, widespread incident; having this information ready prevents redundant troubleshooting and accelerates the creation of a service request. On the MS-102 exam, this question tests your understanding of the support escalation process and common troubleshooting workflows, often appearing as a “choose two” scenario where distractors like “last sign-in time” or “license count” seem plausible but are not required. A common trap is assuming you need error logs first, but Microsoft Support always starts with service health. Memory tip: “Tenant ID for identity, Service Health for severity.”
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 a critical service issue is affecting all users. Which two pieces of information should the administrator have readily available before contacting support? (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
The Tenant ID (A) is a unique, immutable identifier for the Microsoft 365 tenant, required by Microsoft Support to locate the tenant in their systems and verify administrative access. The current service health status (C) is critical because the support engineer will first check the Microsoft 365 Service Health Dashboard (admin.microsoft.com/Adminportal/Home?source=applauncher#/servicehealth) to confirm the issue is a known service incident; having this information ready avoids redundant troubleshooting and speeds up the creation of a service request.
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.
✓
Tenant ID
Why this is correct
The Tenant ID is required to verify the organization and locate the tenant in support systems.
Related concept
Read the scenario before looking for a memorised answer.
✗
User principal names of affected users
Why it's wrong here
For a tenant-wide issue, individual user details are not needed; support needs tenant-level info.
✓
Current service health status
Why this is correct
The support team will ask for the service health dashboard status to confirm the issue and find any active advisories.

✗
Billing contact information
Why it's wrong here
Billing info is related to commercial aspects, not technical support requests.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume user principal names (UPNs) are needed for any support request, but Microsoft Support requires the Tenant ID and service health status for tenant-wide issues, not individual user identifiers.
Detailed technical explanation
How to think about this question
The Tenant ID is a GUID (Globally Unique Identifier) stored in Azure AD and can be retrieved via the Azure portal, Microsoft 365 admin center, or PowerShell (Get-AzureADTenantDetail). The Service Health Dashboard uses the Microsoft 365 Service Communications API to provide real-time incident status; having the current status (e.g., advisory or incident ID) allows the support engineer to immediately correlate the issue with an existing service degradation, bypassing initial triage 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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Variation 1. 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.)
medium
✓ A.Tenant ID (or Microsoft 365 tenant domain name)
B.Number of affected users
✓ C.Detailed description of the problem and troubleshooting steps attempted
D.Network bandwidth graph from the past 24 hours
Why A: 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.
