1Z0-997-26 Workload Migration Practice Question
Your organization is designing a disaster recovery strategy as part of a workload migration project to OCI. The business requirement states that in the event of a regional outage in OCI region A, workloads must fail over to OCI region B with a Recovery Point Objective (RPO) of zero and a Recovery Time Objective (RTO) of less than 15 minutes. Which OCI networking feature should you deploy to interconnect the two regions for database replication?
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
✓
OCI Dynamic Routing Gateway (DRG) with Remote Peering Connection (RPC)
To connect VCNs across different OCI regions with low latency and high security for database replication (such as Data Guard), you should use OCI Remote Peering across Local Peering Gateways or Remote Peering Connections (RPC) through Dynamic Routing Gateways (DRGs).
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 Local Peering Gateway (LPG)
Why it's wrong here
LPGs can only peer VCNs within the same OCI region, not across different regions.
- ✓
OCI Dynamic Routing Gateway (DRG) with Remote Peering Connection (RPC)
Why this is correct
DRG with RPC enables secure, high-bandwidth peering of VCNs across different OCI regions over Oracle's backbone network.
- ✗
OCI Service Gateway
Why it's wrong here
Service Gateway provides private access to Oracle services (like Object Storage) within the same region, not cross-region VCN-to-VCN connectivity.
- ✗
OCI Internet Gateway with IPsec VPN tunnels over the public internet
Why it's wrong here
Routing inter-region traffic over public IPsec VPN tunnels introduces unnecessary latency and bandwidth bottlenecks compared to backbone RPC peering.
