Domain 4.3: Design migrations

An enterprise is planning to migrate 800 VMware virtual machines to Azure. Before migrating, the architecture team needs to understand the network dependencies between the VMs to group them into accurate migration waves. They want to collect this dependency data without installing any agents on the guest operating systems of the 800 VMs. Which Azure Migrate feature should you use?

You are planning to migrate a 5 TB on-premises Oracle database to Azure Database for PostgreSQL. The business requires that the migration process causes no more than 15 minutes of downtime for the application. Which TWO components are required to achieve this near-zero downtime migration? (Select TWO)

A company has a legacy monolithic application running on an on-premises Windows Server 2008 R2 virtual machine. The application code is lost, and it cannot be modified or recompiled. The company wants to move this application to Azure to close their on-premises datacenter. They want to minimize the effort and risk of the migration. Which migration strategy (from the 7 R's) should you recommend?

A research institute needs to migrate 200 Terabytes of scientific data from their on-premises SAN to Azure Data Lake Storage Gen2. Their datacenter has a 100 Mbps internet connection, which is heavily utilized by daily operations. They calculate that transferring this data over the network would take over 6 months. They need the data in Azure within 3 weeks. Which Azure service should you recommend?

You are planning a massive migration of 500 VMware virtual machines from an on-premises datacenter to Azure. You need to discover the VMs, assess their readiness for Azure, and map the network dependencies between the VMs to group them into migration waves. The security team strictly prohibits installing any agents or software directly on the guest operating systems of the VMs. Which tool should you use?

A hospital is migrating a 10 TB on-premises Oracle database to Azure Database for PostgreSQL. The database supports a critical patient care application. The migration must result in near-zero downtime. The application can only be taken offline for a maximum of 15 minutes to update connection strings. Which TWO tools/services must you use in combination to achieve this migration? (Select TWO)

A company has 50 legacy ASP.NET web applications running on Windows Server 2012 IIS servers on-premises. The company wants to modernize these applications by migrating them to Azure App Service. Before migrating, they need to assess which applications are compatible with App Service and identify any code changes required (e.g., unsupported IIS features, hardcoded paths). Which tool should you use?

A media production company needs to migrate 150 TB of historical video archives from their on-premises SAN to Azure Blob Storage. The company's datacenter has a 100 Mbps internet connection. This connection is heavily utilized by daily operations, and only 20 Mbps can be dedicated to the migration effort. You need to recommend a migration strategy that completes the transfer as quickly as possible without impacting daily operations. What should you recommend?

CASE STUDY: Tailspin Toys Tailspin Toys is a global manufacturing company with 50,000 employees across 30 countries. They currently operate a mix of on-premises infrastructure (500 servers across 5 data centers) and Azure (20 subscriptions with 100+ VMs and various PaaS services). Their annual IT budget is $50 million, with plans to migrate 70% of workloads to Azure within 2 years. Business Requirements: The company needs to reduce IT costs by 30%, improve disaster recovery (current RTO: 24 hours -> target: 2 hours), enhance security posture to meet ISO 27001 and SOC 2 compliance, and enable remote work for 80% of employees. All solutions must support future growth of 20% annually. Technical Constraints: Some legacy applications cannot be modified and must run on Windows Server 2012. Network connectivity requires 10 Gbps throughput to Azure with <20ms latency. GDPR compliance mandates that EU customer data must remain in European Azure regions. You need to design a migration strategy for the legacy Windows Server 2012 applications. The solution must minimize operational overhead and maintain compliance while ensuring the applications remain supported. Which compute solution should you recommend?

You are planning the migration of 200 on-premises VMware virtual machines to Azure. You need to group the VMs into 'migration waves'. To do this accurately, you must understand which VMs communicate with each other so you don't migrate a web server without its corresponding database server. You want to gather this data automatically over a 30-day period. Which Azure Migrate feature should you use?

You are designing the migration of a mission-critical 5 TB Oracle database to Azure Database for PostgreSQL. The business requires that the database migration results in near-zero downtime for the application. The application will be pointed to the new Azure database during a brief 15-minute maintenance window. Which migration strategy and tool should you recommend?

Your company is migrating a portfolio of applications to Azure. One specific application is a monolithic ASP.NET web app running on Windows Server 2008. The development team wants to move it to Azure App Service to reduce operational overhead. They will use the Azure App Service Migration Assistant to package the app and deploy it to Azure without changing the application's source code. Which migration strategy (from the 7 R's) does this represent?
