Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A NAT Gateway with public IP attachment
Why it's wrong here
NAT Gateways provide general internet access, whereas Oracle services can be accessed privately via Service Gateways.
- ✗
An Internet Gateway with security list ingress rules
Why it's wrong here
Internet Gateways require public IPs and expose instances to the internet.
- ✓
A Service Gateway and a route table rule pointing traffic destined for Oracle Services to the Service Gateway
Why this is correct
Service Gateways enable private access to Oracle services (such as OS Management) from private subnets.
- ✗
A Local Peering Gateway connected to Oracle's internal network
Why it's wrong here
Local peering connects VCNs, not VCNs to Oracle regional services.
