AZ-400 Configure processes and communications Practice Question
This AZ-400 practice question tests your understanding of configure processes and communications. 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.
Your team is migrating from on-premises TFS to Azure DevOps Services. You need to ensure that all existing work item history and attachments are preserved. Which migration approach should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the Azure DevOps Migration Tools (open source)
Option C is correct because the Azure DevOps Migration Tools (an open-source project) are specifically designed to migrate work items, including history, attachments, and links, from on-premises TFS to Azure DevOps Services. These tools handle the complex data transformations required to preserve the full fidelity of work item data, which is not possible with simpler export/import methods.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Export to Excel and import using Azure DevOps Office Integration
Why it's wrong here
Excel import does not preserve history or attachments.
✗
Manually recreate work items in Azure DevOps
Why it's wrong here
Manual recreation loses all historical data.
✓
Use the Azure DevOps Migration Tools (open source)
Why this is correct
These tools are designed to preserve full history, attachments, and links.

✗
Use the Azure DevOps REST API to migrate work items
Why it's wrong here
The REST API can migrate data but requires extensive custom code and does not preserve all history.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume the REST API is sufficient for full migration, but it lacks built-in support for preserving history and attachments, requiring custom development that is more error-prone than using the purpose-built open-source tools.
Detailed technical explanation
How to think about this question
The Azure DevOps Migration Tools use the TFS/Azure DevOps REST API under the hood but implement batching, retry logic, and field mapping to preserve revision history, work item links, and attachments as blobs. A subtle behavior is that the tools can handle field mappings between different process templates (e.g., Scrum to Agile) and can migrate test cases, shared steps, and test plans, which are often overlooked in manual or API-only approaches. In real-world scenarios, organizations with thousands of work items and years of history rely on these tools to maintain audit trails and regulatory compliance.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
