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
✓
An authorized admin must submit a support request to Microsoft.
Option A is correct because Customer Lockbox requires an authorized admin to explicitly approve or deny a Microsoft engineer's access request. This ensures that no data access occurs without the customer's explicit consent, aligning with the principle of 'approval-based access control' for support scenarios.
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
The trap here is that candidates often confuse Customer Lockbox with internal admin access controls (like Privileged Access Management) or assume it's available on lower-tier plans like E3, when in fact it requires E5/G5 licensing and is specifically for Microsoft-initiated support access.
Detailed technical explanation
How to think about this question
Customer Lockbox operates by intercepting Microsoft engineer access requests at the tenant boundary, requiring an authorized admin (e.g., Global Admin or Compliance Admin) to approve or deny within a defined time window (typically 12 hours). Under the hood, it integrates with Microsoft's Just-In-Time (JIT) access system and Azure AD audit logs, ensuring all approval actions are recorded for compliance. In a real-world scenario, if a Microsoft engineer needs to troubleshoot a critical Exchange Online issue, the Lockbox workflow ensures the customer retains control over data access, which is crucial for regulated industries like finance or healthcare.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
