Part A

Quiz

20 exam-style questions, roughly in the order of the units. Click an answer to see the explanation. Your best score is saved and shown on the path page; use Retry at the end to go again.

1. Which CAF methodology covers moving existing workloads to Azure?

C. Adopt covers migration and innovation; Ready prepares the landing zone before.

2. A VM moves to Azure as-is with no code changes. Which migration strategy?

C. Rehost changes the hosting, not the application.

3. An app moves from VMs to App Service with only configuration changes. Which strategy?

A. Small changes to run on PaaS are refactoring/replatforming.

4. A monolith is split into microservices on AKS during migration. Which strategy?

C. Rearchitecting changes the application's architecture to use cloud-native capabilities.

5. An on-premises CRM is replaced by Dynamics 365. Which strategy?

B. Moving to a SaaS product replaces the workload.

6. What's the central hub for discovery, assessment and migration of servers, databases and web apps?

C. Azure Migrate integrates discovery, assessment and migration tools.

7. How does Azure Migrate discover on-premises VMware VMs agentlessly?

A. The appliance discovers servers, performance data and dependencies.

8. Which assessment sizing gives right-sized Azure VMs based on actual utilization?

A. Performance-based sizing uses collected CPU, memory and disk data; as-is sizing copies on-premises specs.

9. Before migrating, you need to know which servers talk to each other so you move them together. Which feature?

C. Dependency analysis (agentless or agent-based) maps server-to-server connections.

10. Which program offers guidance, tools, partners and incentives for migrations?

A. The program combines expert guidance, partners and offers to accelerate migration.

11. Which tool estimates savings and TCO of moving to Azure, including licensing benefits?

C. The business case compares on-premises cost with Azure cost, including Azure Hybrid Benefit.

12. Windows Server and SQL Server licenses with Software Assurance can be reused in Azure to cut costs. What's this called?

B. Azure Hybrid Benefit applies existing licenses to Azure VMs and SQL services.

13. On-premises SQL Server databases must move to Azure SQL Managed Instance with minimal downtime. Which tool?

A. DMS supports online migrations that keep the target in sync until cutover.

14. Which tool checks SQL Server databases for compatibility issues and recommends the right Azure SQL target and size?

C. Assessment tools flag blocking issues and right-size the target SKU.

15. What's the difference between an online and an offline database migration?

A. Online migration minimizes downtime to the final cutover.

16. A one-time copy of 5 TB from an on-premises file server to Blob Storage over a fast network, scripted. Which tool?

A. AzCopy is the command-line tool for high-performance copies to and from Azure Storage.

17. File servers must be migrated while users keep working, with files tiered to Azure gradually. Which option?

B. File Sync keeps on-premises and cloud in sync during and after migration.

18. Which service orchestrates online file share migrations (e.g. NAS to Azure Files) with discovery and scheduling?

D. Storage Mover is a managed migration service for file shares.

19. 80 TB must be moved to Azure; the network link would take months. Which option?

A. Data Box ships a secure device (about 80 TB usable); Data Box Heavy handles up to ~1 PB.

20. A few TB on your own disks must be shipped to an Azure datacenter. Which service?

D. Import/Export uses your own drives; Data Box uses Microsoft-supplied devices.

Part B

Design exercise

On paper · about 25 minutes

Ridgeway Manufacturing leaves its datacenter within 12 months.

  1. Task

    Assess and build the business case

    Describe the discovery and assessment steps and the cost levers.

    Done when
    • Discovery, dependencies and sizing are covered.
    • At least two cost levers are named.
    Model answer

    Azure Migrate appliance → discovery + performance data (≥1 month) + agentless dependency analysis → move groups → performance-based assessments → business case. Cost: Azure Hybrid Benefit, reservations/savings plan, right-sizing, retire unused servers.

  2. Task

    Choose a strategy per workload

    Apply the Rs to VMs, the planning app, the SQL databases and the intranet.

    Done when
    • Every workload has an R.
    • The ERP downtime target is respected.
    Model answer
    • Most VMs: rehost with Azure Migrate server migration.
    • Planning app: refactor to App Service (App Service migration assistant).
    • SQL: assess, then SQL Managed Instance; ERP via DMS online migration (cutover < 30 min).
    • Intranet: retire.
  3. Task

    Move the files

    Plan the CAD archive and the active shares.

    Done when
    • Offline and online transfer are both used where appropriate.
    Model answer

    Archive: Data Box (two devices or Data Box Heavy) into Blob (Cool/Cold), then delta sync with AzCopy. Active shares: Azure File Sync (or Storage Mover) to Azure Files with a short cutover.
