- A
Enable Azure DevOps Audit Streams to send audit events to a Log Analytics workspace. Configure a Log Analytics workspace with 7-year retention. Create a dashboard and alert rules for compliance.
Audit Streams captures all required events and Log Analytics provides long-term retention and near real-time querying.
- B
Use Azure Event Grid to subscribe to pipeline run events and store them in Azure Cosmos DB with TTL for 7 years.
Why wrong: Event Grid does not provide built-in retry or guaranteed ordering, and Cosmos DB TTL is not suitable for retention compliance.
- C
Add a step at the end of each pipeline to upload pipeline logs as pipeline artifacts with a retention policy of 7 years.
Why wrong: Artifacts do not capture secret access events or user identity in a queryable format.
- D
Instrument each pipeline with custom tasks that send telemetry to Application Insights. Set Application Insights to 7-year retention.
Why wrong: Application Insights is not designed for audit logs and may not capture secret access events.
AZ-400 Implement an instrumentation strategy Practice Question
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 the DevOps lead for a fintech company. The organization uses a multi-tenant Azure DevOps environment with hundreds of pipelines. The compliance team requires that every pipeline run must be auditable with the following attributes captured: who triggered the run, what code changes were included, which artifacts were produced, and whether any secrets (e.g., Azure Key Vault references) were accessed during the run. Additionally, all audit data must be retained for 7 years and be queryable within 5 minutes of a pipeline completion. Current state: pipelines use Azure Key Vault for secrets, and YAML pipelines are defined with variables referencing Key Vault. You need to design an instrumentation strategy to meet these requirements. What should you do?
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
Enable Azure DevOps Audit Streams to send audit events to a Log Analytics workspace. Configure a Log Analytics workspace with 7-year retention. Create a dashboard and alert rules for compliance.
Option A is correct because using Azure DevOps Audit Streams to send events to a Log Analytics workspace provides long-term retention and near real-time querying. Azure DevOps Audit logs capture all required attributes including pipeline runs, secret access, and user identity. Application Insights (B) is for application telemetry, not pipeline audit. Event Grid (C) is event-driven but doesn't store historical data for 7 years query. Pipeline artifacts (D) don't include audit trail of who triggered or secret access.
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
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
How to think about this question
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.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
