MS-900 Practice Question: Describe Microsoft 365 pricing, licensing, and support
This MS-900 practice question tests your understanding of describe microsoft 365 pricing, licensing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 is reviewing an ARM template for a storage account. The template includes a storage account with Standard_LRS redundancy. Which Microsoft 365 licensing feature does this relate to?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Purview audit log storage
The ARM template's Standard_LRS redundancy is used for Azure storage accounts, which underpin Microsoft 365's audit log storage in Microsoft Purview. Audit logs are stored in Azure Blob Storage, and Standard_LRS (Locally Redundant Storage) is the default redundancy tier for this data, providing three copies within a single datacenter. This directly links to the Purview audit log storage feature, not user-facing storage quotas or limits.
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.
✗
OneDrive for Business storage
Why it's wrong here
OneDrive storage is part of SharePoint Online.
✓
Microsoft Purview audit log storage
Why this is correct
Purview can use Azure Storage accounts for long-term retention of audit logs, and ARM templates can be used to deploy the storage.

Read the scenario before looking for a memorised answer.
✗
SharePoint Online storage quotas
Why it's wrong here
SharePoint Online uses its own storage, not ARM-deployed storage accounts.
✗
Exchange Online mailbox limits
Why it's wrong here
Exchange Online mailboxes are not provisioned via ARM templates.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Azure storage redundancy (Standard_LRS) with Microsoft 365 user storage features like OneDrive or SharePoint quotas, but the question specifically ties to the backend infrastructure for audit log storage in Microsoft Purview.
Detailed technical explanation
How to think about this question
Microsoft Purview audit log storage uses Azure Blob Storage with Standard_LRS as the default redundancy, meaning data is replicated three times within a single Azure region's datacenter. For compliance and eDiscovery scenarios, organizations can increase redundancy to GRS or RA-GRS for cross-region disaster recovery, but this incurs additional costs. The ARM template's Standard_LRS setting directly maps to the underlying Azure storage account that hosts audit logs, which is separate from user-facing storage services like OneDrive or SharePoint.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
