Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OCI API Gateway
Why it's wrong here
API Gateway is designed for managing HTTP/REST API endpoints, not database TCP/IP replication traffic.
- ✗
An Internet Gateway with public IP addresses
Why it's wrong here
Routing sensitive database redo logs over the public internet is a security risk and unnecessary when using remote VCN peering or DRGs.
- ✓
Remote VCN Peering
Why this is correct
Remote VCN Peering connects VCNs across different regions, allowing secure IP communication for Data Guard redo transport.
- ✗
Local VCN Peering gateway
Why it's wrong here
Local VCN peering is restricted to resources within the same region.
