Which OCI service or feature is best suited for capturing and analyzing network traffic metadata...

Goal: Capture and analyze traffic metadata for anomalies and troubleshooting.

Option A: NSGs control traffic but don’t capture metadata—incorrect.

Option B: Flow Logs record detailed traffic metadata (e.g., IPs, ports), perfect for analysis—correct.

Option C: Route Tables manage routing, not metadata—incorrect.

Option D: Service Gateway enables service access, not traffic logging—incorrect.

Conclusion: Flow Logs are best suited.

Oracle documentation confirms:

"Flow Logs capture network traffic metadata within a VCN, enabling anomaly detection and connectivity troubleshooting.”This supports Option B. Reference:Flow Logs Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/flowlogs.htm).
