1Z0-997-26 Security Practice Question
You are configuring a Remote Peering Connection (RPC) between two Dynamic Routing Gateways (DRGs) in different OCI regions. What is required to ensure secure, private data transmission between the two VCNs?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Establish a Remote Peering Connection between the DRGs and configure matching route table entries and security rules.
Remote VCN peering across regions requires a DRG attachment for each VCN, an RPC configured on both DRGs, and a peering connection request accepted by the target region's DRG, with appropriate security lists and routing tables.
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 public IP addresses on all participating compute instances.
Why it's wrong here
Public IP addresses are unnecessary for private remote VCN peering.
- ✓
Establish a Remote Peering Connection between the DRGs and configure matching route table entries and security rules.
Why this is correct
RPCs leverage Oracle's private backbone, requiring proper DRG configuration, peering acceptance, route tables, and security lists.
- ✗
Route all inter-region traffic through public Internet Gateways with IPsec tunneling.
Why it's wrong here
RPCs traverse the private Oracle backbone network without requiring internet gateways or IPsec tunnels.
- ✗
Deploy an OCI NAT Gateway in each region.
Why it's wrong here
NAT Gateways are for outbound internet access, not inter-region VCN communication.
