You can download the full log or view summarized output (build duration, test results, artifact links, etc.). Follow: Example scenario: If your .NET build failed during dotnet test, you open the “Test” step log — Azure DevOps shows which specific test failed, the error message, and even a link to the exact line of code if integrated with Repos. Tip: You can also use log filters (e.g., “Errors only”) to focus on failed tasks quickly. 2⃣ How do you troubleshoot failed builds or deployments?

Troubleshooting starts by identifying where and why the pipeline failed. Steps:

What interviewers expect

• A clear definition tied to DevOps in Azure DevOps projects
• Trade-offs (performance, maintainability, security, cost)
• When you would and would not use it in production

Real-world example

In a production Azure DevOps application, teams apply this when handling user-facing features or integration boundaries. For example, you might use it during a sprint where reliability and observability matter—logging metrics, validating edge cases, and documenting the decision in an ADR so future developers understand why the approach was chosen.

How to explain in the interview

1. Define the concept in one or two sentences.
2. Context — where it fits in Azure DevOps architecture.
3. Example — a specific project, bug, or performance win.
4. Trade-off — what you gain vs what you sacrifice.

Tip: Practice aloud on Toolliyo mock interview or the Interview Q&A section before your real interview.
