This AZ-400 practice question tests your understanding of implement an instrumentation strategy. 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 are deploying a Java application to Azure App Service using Azure Pipelines. You want to automatically capture JVM metrics (heap usage, garbage collection) and correlate them with deployment events. What should you do?
Use Azure Monitor diagnostic settings for the App Service.
Why wrong: For Azure platform logs.
Enable Application Insights Java agent in the App Service.
Automatically collects JVM metrics.
Attach a profiler from Visual Studio to the App Service process.
Why wrong: Not suitable for production.
Configure App Service diagnostic logs to capture stdout/stderr.
Why wrong: Does not capture JVM internals.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable Application Insights Java agent in the App Service.
Option A is correct because Application Insights Java agent automatically collects JVM metrics and can be correlated with deployment markers. Option B is wrong because App Service logs don't include JVM metrics. Option C is wrong because diagnostic settings are for Azure resource logs, not JVM. Option D is wrong because Visual Studio profiler is not a production monitoring tool.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Use Azure Monitor diagnostic settings for the App Service.
Why it's wrong here
For Azure platform logs.
Enable Application Insights Java agent in the App Service.
Why this is correct
Automatically collects JVM metrics.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
