MS-900 Practice Question: A company with 1,000 users has Microsoft 365 E3…
A company with 1,000 users has Microsoft 365 E3 subscriptions. They are experiencing a major outage affecting all users and need guaranteed 1-hour response time for a critical support issue. What should they purchase?
⚠ Common exam trap
Test-takers frequently assume Standard Support (included) always provides a 1-hour critical response, but Microsoft differentiates response times by subscription type (Business vs. Enterprise), and for E3 (Enterprise), the critical response is 2 hours, not 1.

Correct answer & explanation
✓
Professional Direct Support
Professional Direct Support provides a guaranteed 1-hour response time for critical severity issues, which is required for the company's major outage affecting all 1,000 users. Standard Support, included with Microsoft 365 E3, offers a 1-hour response for critical issues only for Business-level subscriptions; for Enterprise subscriptions like E3, the critical response time is 2 hours. Professional Direct Support also includes proactive guidance and a named support engineer, making it the correct choice for guaranteed 1-hour response.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Standard Support (included)
Why it's wrong here
The Standard Support plan included with Microsoft 365 E3 provides unlimited incident submission and access to Microsoft documentation, but it does not include any guaranteed response time. Response times for incident requests vary based on severity and can be significantly longer than one hour, especially for lower-severity issues. Additionally, Standard Support does not offer proactive services or dedicated technical account management, which are only available through paid support offerings like Professional Direct.

Professional Direct Support
Why this is correct
Professional Direct Support is a paid support add-on for Microsoft 365 that provides a guaranteed one-hour response for critical severity (Sev A) issues, ensuring urgent problems are addressed promptly. It also includes proactive services such as health checks, change management assistance, and access to Microsoft subject matter experts. This plan is specifically designed for organizations that require rapid, SLA-backed assistance and ongoing technical guidance.
- ✗
Azure Support Basic
Why it's wrong here
Azure Support Basic is a free support plan that is exclusive to Microsoft Azure services, not Microsoft 365. It provides only billing and subscription-related assistance and does not cover technical troubleshooting for Microsoft 365 workloads. Therefore, while the company may use Azure, this plan would not provide any support for their Microsoft 365 E3 subscription, let alone a one-hour response guarantee.
- ✗
Partner support via a Microsoft CSP
Why it's wrong here
Cloud Solution Provider (CSP) partners can offer support for Microsoft 365, but the response time and service quality are determined by the partner's own operational agreements, not by Microsoft. Microsoft does not automatically guarantee a one-hour response when using a CSP; such a commitment would need to be explicitly contracted in the partner agreement. Unless the partner has signed a specific SLA with the customer, the support experience can vary significantly, so this option does not meet the requirement.
