Oracle Cloud Infrastructure 2019 Developer Associate — Question 89

You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical data. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public internet.
Which is the recommended disaster recovery plan?

Answer options

• A. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.
• B. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.
• C. Create a DR environment in Ashburn and provision a FastConnect virtual circuit using DRG between the regions.
• D. Create a DR environment in Ashburn. Associate a dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.

Correct answer: A

Explanation

Option A is correct because it allows for VCN peering within the same region, ensuring that the DR site is adequately isolated from the production environment while remaining compliant with the requirements. The other options involve either remote peering or VPN connections, which may not meet the criteria of keeping data transfer off the public internet or do not utilize the same region effectively.
