Oracle Cloud Infrastructure 2020 Architect Associate — Question 5

Your company decided to move a few applications to Oracle Cloud Infrastructure (OCI) in the US West (us-phoenix-1) region.
You need to design a cloud-based disaster recovery (DR) solution with a requirement to deploy the DR resources in the US East (us-ashburn-1) region to minimize network latency.
What is the recommended deployment?

Answer options

• A. Deploy production and DR applications in two separate virtual cloud networks (VCNs), each in different regions, and then use VCN local peering gateways for connectivity.
• B. Deploy production and DR applications in two separate VCNs, each in different regions. Connect them using a VCN remote peering connection.
• C. Deploy production and DR applications in the same VCN. Create production subnets in one AD, and DR subnets in another AD (assume a multi-AD region).
• D. Deploy production and DR applications in two separate VCNs in different availability domains (ADs) within the primary region, and then use a VCN remote peering connection for connectivity.

Correct answer: D

Explanation

The correct answer is D because it ensures that the production and DR applications are separated in different VCNs while also maintaining a connection via a remote peering connection. Options A and C do not meet the requirement of deploying resources in different regions, and option B does not specify the correct availability domain setup for the primary region, which is critical for disaster recovery strategies.
