Correct answer & explanation
✓

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure a Service Gateway in your VCN and add a route rule with the destination set to the Object Storage service CIDR.
Why this is correct
A Service Gateway allows your VCN to securely access OCI services like Object Storage privately over OCI's internal network backbone.
- ✗
Attach a NAT Gateway to your VCN and route traffic destined for Object Storage through it.
Why it's wrong here
A NAT Gateway provides outbound internet access for private subnets, which is not required for private regional access to OCI services.
- ✗
Deploy an Internet Gateway and use security lists to block all inbound traffic except Object Storage traffic.
Why it's wrong here
An Internet Gateway connects a VCN to the public internet, which violates the requirement of avoiding the public internet.
- ✗
Set up a Local Peering Gateway and peer your VCN directly to the Object Storage public namespace.
Why it's wrong here
A Local Peering Gateway is used to connect two VCNs within the same region, not for connecting a VCN to OCI native services.
