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. The recommended disaster recovery plan is
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 DRsites.
Step-by-step explanation:
- Local VCN peering is the process of connecting two VCNs in the same region and tenancy so that their resources can communicate using private IP addresses without routing the traffic over the internet or through your on-premises network.
- You have a central VCN that has resources that you want to share with other VCNs.
- A VCN is a customizable private network in Oracle Cloud Infrastructure. Just like a traditional data center network, a VCN provides you with complete control over your network environment.
- A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments.
- A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice.
