Artifact Analysis archives vulnerability metadata in Cloud Storage buckets. When images are scanned, recent vulnerability data is typically available through Artifact Analysis APIs, but metadata older than 30 days is retained in Cloud Storage. To compile a compliance report that includes older images, you need to check the Artifact Analysis storage buckets where this archived data is kept.
• Option A: A Pub/Sub subscription only captures events from the point of subscription onward and would not contain older metadata.
• Option C: Pulling images from Artifact Registry does not provide historical vulnerability metadata.
• Option D: Cloud Trace logs do not store the detailed vulnerability findings required for your compliance report.
