You are managing a critical application hosted on OCI. To enhance security, you have enabled DNSSEC for your domain using OCI DNS. You want to automate the process of monitoring the health and validity of your DNSSEC configuration and receive alerts if any issues are detected. Which OCI service can be MOST effectively used for this DNSSEC monitoring purpose?

Goal: Automate DNSSEC health monitoring with alerts.
Option A: Vulnerability Scanning is for compute instances, not DNSSEC—incorrect.
Option B: Monitoring Service tracks metrics and logs, supports custom DNSSEC metrics, and provides alarms—correct.
Option C: Audit Service logs API calls, not DNSSEC health—incorrect.
Option D: Logging Analytics analyzes logs but lacks direct alerting—less effective than Monitoring. Conclusion: Option B is the most effective for automated monitoring and alerts. Oracle documentation notes: "OCI Monitoring Service allows you to monitor metrics and logs, including DNSSEC-related data, and set alarms for proactive notifications." This supports Option B.
