In a scenario where you are tasked with deploying a multi-tier application on Microsoft Azure, the application consists of a web front end, an application logic tier, and a database tier. Each tier has distinct requirements: the web front end must handle variable traffic loads efficiently, the application logic tier requires high availability and scalability to process business logic, and the database tier needs to support global distribution with low latency for read and write operations. Considering cost optimization, compliance with data residency laws, and the need for minimal management overhead, which combination of Azure services would you choose for each tier? (Choose two correct options)

Explanation:
Option A is correct because Azure Virtual Machines provide the necessary flexibility for the web front end, Azure Virtual Machine Scale Sets ensure scalability and availability for the application logic tier, and Azure SQL Database offers a managed service with high availability for the database tier. Option E is also correct as Azure App Service is a fully managed platform for building web applications, Azure Kubernetes Service offers orchestration for containerized applications ensuring scalability and availability, and Azure Cosmos DB provides global distribution and low latency for the database tier, aligning with the requirements for global reach and minimal management overhead.
