Domain 4.3: Migrations

You are planning a massive migration of 1,000 VMware virtual machines to Azure. You need to discover the VMs, assess their readiness for Azure, right-size them based on historical performance data, and map the network dependencies between the VMs to group them into migration waves. The security team strictly prohibits installing any agents on the guest operating systems of the VMs. Which tool should you use?

You are migrating a mission-critical, on-premises Oracle database to Azure Database for PostgreSQL. The database is 5 TB in size. The business requires that the migration be performed with near-zero downtime. The application will be pointed to the new Azure database during a brief 15-minute maintenance window. Which TWO tools/services should you use in combination to achieve this? (Select TWO)

A research institute has 200 TB of scientific data stored on an on-premises NAS device. They need to migrate this data to Azure Data Lake Storage Gen2. Their on-premises internet connection is only 100 Mbps, and it is heavily utilized by daily operations. They want to complete the migration within 2 weeks. Which migration solution should you recommend?

**CASE STUDY: Contoso Manufacturing** **Overview:** Contoso Ltd is a global manufacturing company with 50,000 employees across 30 countries. They currently operate a mix of on-premises infrastructure (500 VMware VMs 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 R2. Network connectivity requires 10 Gbps throughput to Azure with <20ms latency. GDPR compliance mandates that EU customer data must remain in European Azure regions. **Question:** Contoso is ready to migrate the 500 VMware VMs to Azure. They want to group the VMs into migration waves based on actual network traffic dependencies to ensure multi-tier applications are migrated together. Which Azure Migrate feature should they use?

You are planning a large-scale migration of 500 on-premises VMware virtual machines to Azure. You need to group the VMs into 'migration waves' based on their network dependencies (e.g., Web server talks to App server, App server talks to DB server). The security team prohibits installing any agents on the guest operating systems of the VMs. Which tool and feature should you use?

You are migrating a 5 TB on-premises Oracle database to Azure Database for PostgreSQL. The business requires that the migration results in less than 15 minutes of application downtime. You plan to use the Azure Database Migration Service (DMS). Which TWO actions must you perform to achieve this near-zero downtime migration? (Select TWO)

A media company needs to migrate 150 TB of historical video archives from their on-premises SAN to Azure Blob Storage. Their on-premises internet connection is only 100 Mbps, and it is heavily utilized by daily operations. They need to complete the migration within 3 weeks. Which TWO solutions should you recommend to meet the timeframe without impacting daily operations? (Select TWO)

You are assessing an on-premises ASP.NET web application running on IIS for migration to Azure App Service. You need to determine if the application uses any features that are incompatible with Azure App Service (such as COM components or ISAPI filters) before attempting the migration. Which TWO tools can you use to perform this assessment? (Select TWO)

You are planning a large-scale migration of 500 VMware VMs to Azure. You need to discover the on-premises servers, map their network dependencies to group them into migration waves, and get cost estimates for running them in Azure. Which TWO tools should you use? (Select TWO)

You are migrating a 5 TB on-premises SQL Server database to Azure SQL Managed Instance. The application requires 24/7 availability, and the business has mandated that the migration cutover downtime must be less than 15 minutes. Which migration strategy should you use?

A company wants to migrate a legacy ASP.NET web application to Azure. The application currently runs on Windows Server 2012 R2. The business wants to reduce OS maintenance overhead and leverage auto-scaling, but they do not have the budget to rewrite the application code. Which TWO migration strategies represent a 'Replatform' approach for this application? (Select TWO)

You are planning the migration waves for a complex enterprise environment. You have identified a 3-tier application: Web servers, App servers, and a Database server. The database server is also accessed by a separate reporting application. To ensure minimal disruption and optimal performance post-migration, which TWO principles should guide your wave planning? (Select TWO)

CASE STUDY: Contoso migrating 500 servers to Azure. RTO 2h, RPO 15m, GDPR compliance, 10Gbps ExpressRoute required. QUESTION: You are planning the migration of the 500 servers, including web apps and databases. Which THREE tools should you include in your migration strategy? (Select THREE)

You are planning a migration of 300 VMware VMs to Azure. You need to perform dependency mapping to group VMs into migration waves. Security prohibits installing agents on the VMs. What should you use?

You need to migrate 100 TB of historical video files to Azure Blob Storage. The on-premises internet connection is only 100 Mbps. You need to complete the migration within 2 weeks. What should you use?

You are migrating a mission-critical on-premises SQL Server database to Azure SQL Managed Instance. The migration must have near-zero downtime. Which TWO components should you use? (Select TWO)
