Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Security lists or network security groups allowing traffic on port 1522
Why this is correct
Autonomous Database uses port 1522 for mTLS / TLS connections.
- ✓
DNS configuration to resolve the private IP address of the database endpoint
Why this is correct
