Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Modify the SQL*Net configuration file (sqlnet.ora) stored in the database home.
Why it's wrong here
Shared Autonomous Database instances do not allow direct OS file modifications.
- ✗
Deploy an OCI Web Application Firewall (WAF) policy in front of the database port.
Why it's wrong here
WAF is designed for HTTP/HTTPS web traffic, not Oracle SQL*Net protocol connections.
- ✗
Attach a VCN Security List directly to the Autonomous Database service endpoint IP.
Why it's wrong here
Autonomous Database on shared infrastructure is managed by Oracle; customer VCN security lists cannot be directly attached to shared ATP instances.
- ✓
Configure an Access Control List (ACL) specifying the allowed IP CIDR block in the OCI Console.
Why this is correct
ACLs limit incoming network traffic to specified IP addresses or VCNs.
