    AZ-305 · Question 03 · Domain 1.1: Logging and Monitoring

    You are designing a security monitoring solution using Microsoft Sentinel.

    The compliance department requires that all security incident data and associated logs be retained for exactly 7 years. The data must be available for interactive querying for the first 90 days, and afterward, it must be retained at the lowest possible cost while still being accessible for compliance audits within 48 hours if requested.

    Which data retention strategy should you configure in the Log Analytics workspace?

    Answer options:

    A.

    Set the workspace retention to 7 years.

    B.

    Set the workspace retention to 90 days and export logs to an Azure Storage account with a lifecycle policy moving data to the Archive tier.

    C.

    Set the workspace retention to 90 days and configure Archive tier retention for up to 7 years.

    D.

    Configure a Data Collection Rule to route data older than 90 days to Azure Data Explorer.

    How to approach this question

    Look for the native feature in Log Analytics designed specifically for long-term, low-cost retention.

    Full Answer

    C.Set the workspace retention to 90 days and configure Archive tier retention for up to 7 years.✓ Correct
    Azure Monitor Log Analytics workspaces natively support an Archive tier. You can set the interactive retention (Analytics tier) to 90 days, and then configure the Archive tier to retain the data for up to 7 years. This provides the lowest cost for long-term retention while keeping the data within the workspace for search jobs if an audit occurs.

    Common mistakes

    Choosing the storage account export option. While valid historically, native Archive tier is the current best practice for Sentinel/Log Analytics.
