The answer is Microsoft Purview Audit (Premium). This solution is the correct choice because it provides a default 2-year retention policy for all user and admin activity audit logs, directly meeting the compliance regulation requirement to retain audit logs for 2 years. Additionally, Audit Premium offers faster, historical searches through high-bandwidth access to the Audit Log Search API and intelligent insights, enabling efficient querying of large volumes of data—a capability that Standard Audit lacks, as it only retains logs for 90 days. On the SC-900 exam, this question tests your understanding of the key differences between Audit (Standard) and Audit (Premium), often appearing as a scenario where compliance mandates long-term retention and search performance. A common trap is confusing retention with licensing; remember that Audit Premium is the only Purview solution that extends default retention beyond 90 days. Memory tip: think “Premium for the long-term” — Premium gives you 2 years, Standard gives you 90 days.

Correct answer & explanation
✓
Microsoft Purview Audit (Premium)
Microsoft Purview Audit (Premium) provides a 2-year retention capability for audit logs, which meets the compliance regulation requirement. Additionally, it offers faster, historical searches through features like high-bandwidth access to the Audit Log Search API and intelligent insights, enabling efficient querying of large volumes of audit data. Standard Audit only retains logs for 90 days by default and lacks the performance optimizations for historical searches.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Microsoft Purview Data Lifecycle Management
Why it's wrong here
Data Lifecycle Management manages retention and deletion of content (emails, files), not audit logs.
✗
Microsoft Purview eDiscovery (Premium)
Why it's wrong here
eDiscovery is used for legal hold, search, and export of content, not for audit log retention.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the 90-day default retention of Audit (Standard) with the 2-year requirement, or mistakenly think Data Lifecycle Management or eDiscovery can fulfill audit log retention and search needs, when only Audit (Premium) combines long-term retention with high-performance historical search capabilities.
Detailed technical explanation
How to think about this question
Audit (Premium) leverages a dedicated, high-throughput pipeline that ingests audit records into a separate, optimized store with indexed fields (e.g., Operation, UserId, ClientIP) for sub-second query responses even across millions of events. It supports a 2-year default retention for all audit records (with optional 10-year add-on), and the Audit Log Search API can handle up to 2,000 requests per minute per tenant, compared to Standard's 200 requests per minute. In a real-world scenario, a security team investigating a breach spanning 18 months would use Audit (Premium) to run complex KQL queries across the entire period without timeouts or throttling.

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.
