Question 160
Answert should be 4 Would use VPC with private (DB) and public (WEB) subnets: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_VPC.Scenarios.html Multi AZ requirement forces me to multiply subnets by two. Reasons: For DB: Your VPC must have at least one subnet in at least two of the Availability Zones in the region where you want to deploy your DB instance. A subnet is a segment of a VPC’s IP address range that you can specify and that lets you group instances based on your security and operational needs http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_VPC.WorkingWithRDSIns tanceinaVPC.html For Web: After creating a VPC, you can add one or more subnets in each Availability Zone. Each subnet must reside entirely within one Availability Zone and cannot span zones http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Subnets.html
