A company is designing a VPC for a three-tier application. They need to ensure that the web tier can be accessed from the internet, the application tier can only be accessed by the web tier, and the database tier can only be accessed by the application tier. Which subnet design should they use?

A single subnet with network ACLs

Private subnets for all tiers with a NAT gateway for internet access

Public subnet for web, private subnets for application and database, with security groups controlling traffic

A company wants to deploy an application across multiple Availability Zones to ensure high availability. Where should the EC2 instances be placed?

In the same Availability Zone but different subnets

In different Availability Zones within the same Region

A company has a global application with both static content and dynamic API calls. They want to reduce latency for both types of traffic and also provide a stable endpoint for clients that need to whitelist IP addresses. Which solution should they use?

Use Amazon CloudFront for static content and AWS Global Accelerator for dynamic API traffic

Use Amazon Route 53 with latency-based routing

Use only AWS Global Accelerator for all traffic

Use only Amazon CloudFront for all traffic
