A company is migrating a multi-tier application to Azure. The application consists of a web front end, an application tier, and a database. The security team requires that the database tier is not directly accessible from the internet. Which Azure architecture should be used to meet this requirement?

Place the database tier in a separate VNet and peer it with the application tier's VNet, but give the database a public IP address.

Use Azure App Service for all tiers and rely on the platform's built-in security.

Place all tiers in the same subnet and rely on the database's built-in authentication to protect it.

Place the web and application tiers in a public subnet, and the database tier in a private subnet with no public IP address, using network security groups (NSGs) to control traffic.

A company is migrating a legacy customer relationship management (CRM) application to Azure. During discovery, they find the application has a hard-coded dependency on an on-premises Active Directory (AD) for authentication and a local file share for document storage. The business wants to minimize code changes and avoid re-architecting. Which migration strategy best fits these constraints?

Replatform the application to Azure App Service and use Azure SQL Database for the backend.

Refactor the application to use Azure AD for authentication and Azure Blob Storage for documents.

Rehost the application to Azure VMs and extend the on-premises AD to Azure AD Domain Services, then use Azure Files for the document share.

Retire the CRM and replace it with a SaaS CRM solution.

A financial services firm is migrating a 2 TB transactional database to Azure SQL Managed Instance. The migration window is limited to a 4-hour maintenance window on a weekend. The database must remain available for reads and writes until the final cutover. Which approach should they use to minimize downtime and ensure data consistency?

Use Azure Data Factory to continuously copy the entire database to Azure SQL Managed Instance during the maintenance window.

Perform a full backup, restore to Azure, and then during the maintenance window stop the application, take a tail-log backup, restore it, and switch the connection string.

Stop the application, take a full backup, transfer it to Azure, and restore it. This is the simplest and most reliable method.

Use Azure Site Recovery to replicate the entire database server to Azure and then fail over.

A company is migrating a monolithic application to Azure. The application has a SQL Server database and a web front end. The business wants to reduce infrastructure costs and improve scalability, but they have limited development resources and cannot afford a full rewrite. They also need to maintain the ability to scale the web tier independently from the database. Which migration strategy best meets these requirements?

Replatform the application to Azure App Service and Azure SQL Database, making minimal code changes to support the platform.

Refactor the application into microservices and deploy to Azure Kubernetes Service (AKS).

Replace the application with a SaaS solution.

Rehost the application to Azure VMs and keep the database on-premises.

Which element is essential for a successful rollback plan?

A new database schema for the target

A validated backup of the source environment

A public IP address for the target environment

A plan to delete the source environment immediately
