Developers are testing the application running on 10 EC2 instances managed by an Auto Scaling group in subnet 172.31.0.0\/24 within VPC A with CIDR block 172.31.0.0\/16. The Developers noticed connection timeout errors in the application logs while connecting to an Oracle database running on an Amazon EC2 instance in the same region within VPC B with CIDR block 172.50.0.0\/16.

Change the default route of VPC A to point ENI of the Oracle Database that has an IP address assigned within the range of 172.50.0.0\/16 <br \/><strong>B.<\/strong> Create and attach internet gateways for both VPCs. Configure default routes to the internet gateways for both VPCs.
