- A
Set up log shipping to an Azure SQL Database
Why wrong: Log shipping is not supported for Azure SQL Database; it only works with SQL Server on VMs.
- B
Perform an offline migration using Azure Database Migration Service
Why wrong: Offline migration requires downtime and still needs to address non-supported features like FileTables.
- C
Export a BACPAC file from the source and import it to Azure SQL Database
Why wrong: BACPAC export/import is offline and may fail if the database contains unsupported features.
- D
Use Azure Database Migration Service with online mode after removing FileTables
Online migration minimizes downtime. Remove unsupported features first, then migrate using DMS.

DP-300 Plan and implement data platform resources Practice Question
This DP-300 practice question tests your understanding of plan and implement data platform resources. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You need to migrate an on-premises SQL Server 2019 database to Azure SQL Database with minimal downtime. The database is 500 GB and uses some features not supported in Azure SQL Database, such as FileTables. What is the best migration strategy?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Azure Database Migration Service with online mode after removing FileTables
Option D is correct because Azure Database Migration Service (DMS) with online mode supports minimal-downtime migrations by continuously replicating ongoing changes from the source SQL Server to Azure SQL Database. However, FileTables are not supported in Azure SQL Database, so they must be removed from the source database before migration. This approach ensures near-zero downtime while addressing the unsupported feature.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume log shipping (Option A) is viable for Azure SQL Database, but log shipping is not supported for Azure SQL Database as it requires SQL Server Agent and file-level restore operations, which are not available in that PaaS offering.
Detailed technical explanation
How to think about this question
Azure Database Migration Service online mode uses the transactional replication technology under the hood to capture and apply changes from the source to the target continuously. The migration involves an initial full data load followed by a continuous sync phase, and only at the final cutover is a brief pause required. In real-world scenarios, removing unsupported features like FileTables may require redesigning the application to use Azure Blob Storage or alternative file storage solutions before migration.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
