Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Autonomous Database Access Control Lists (ACLs).
Why this is correct
ACLs restrict public IP access to specific allowed ranges on public Autonomous Database endpoints.
- ✗
Virtual Cloud Network (VCN) Security Lists only.
Why it's wrong here
Security lists apply to VCN subnets, but public Autonomous Databases require Access Control Lists for IP filtering.
- ✗
OCI Web Application Firewall (WAF) rule sets.
Why it's wrong here
WAF is designed for HTTP/HTTPS web traffic, not direct SQL database connections (TNS/JDBC).
- ✗
OCI Identity and Access Management (IAM) dynamic groups.
Why it's wrong here
IAM dynamic groups are for resource authentication, not network-level IP filtering.
