Correct answer & explanation
✓
To retrieve audit records of file access and modifications in the HR SharePoint site from the last 90 days.
The PowerShell cmdlet `Search-UnifiedAuditLog` is used to retrieve audit records from the Microsoft 365 unified audit log. The `-StartDate` and `-EndDate` parameters define the time range (last 90 days), and the `-RecordType` parameter filters for SharePoint audit events. The `-Operations` parameter with `FileAccessed` and `FileModified` specifies that only file access and modification events should be returned, making this command's purpose to retrieve audit records of file access and modifications in the HR SharePoint site from the last 90 days.
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 may confuse the `Search-UnifiedAuditLog` cmdlet with cmdlets that manage retention or deletion, because the question mentions 'files' and '90 days' which can mislead test-takers into thinking it applies a policy or deletes data, when in fact it only retrieves audit records.
Trap categories for this question
Command / output trap
Retention policies are not set via this command.
Detailed technical explanation
How to think about this question
The unified audit log in Microsoft 365 captures events from Exchange Online, SharePoint Online, OneDrive for Business, Azure AD, and other services. The `Search-UnifiedAuditLog` cmdlet queries the AuditLog service via the Office 365 Management Activity API, and results can be exported or piped to other cmdlets for analysis. In real-world scenarios, this command is often used for forensic investigations or compliance audits to track user activity, such as identifying unauthorized access or data exfiltration attempts.

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.
