Answer: Use public and private subnets, with the web tier in public subnets and the application and database tiers in private subnets
The recommended strategy for network segmentation in this scenario is to use public and private subnets, with the web tier in public subnets (accessible from the internet) and the application and database tiers in private subnets (not accessible from the internet). This isolates the sensitive components from direct internet access while allowing the web tier to be publicly accessible.
