Quick Answer
The answer is Azure Monitor. This is correct because an automated rollback for AKS deployments based on error rate relies on Azure Monitor to collect and analyze metrics like HTTP 5xx errors or request failures, which can then trigger a rollback through Azure DevOps release gates or a canary deployment strategy. On the AZ-204 exam, this tests your understanding of how to integrate monitoring with deployment pipelines—a common trap is confusing Azure Monitor’s detection role with the actual rollback mechanism, which is handled by Azure DevOps or progressive exposure tools. Remember that Azure Monitor is the observability engine that feeds error-rate data into your rollback logic, not the rollback executor itself. Memory tip: “Monitor detects, DevOps corrects.”
This AZ-204 practice question tests your understanding of monitor, troubleshoot, and optimize azure solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 using Azure DevOps to deploy an Azure Kubernetes Service (AKS) cluster. You want to automatically roll back a deployment if the new version causes a high error rate. Which Azure service should you use to implement this?
Azure Service Health
Why wrong: Service Health notifies about Azure outages, not deployment errors.
Azure Monitor
Azure Monitor can detect error rates and trigger alerts that can be used by Azure DevOps for rollback.
Azure Traffic Manager
Why wrong: Traffic Manager routes traffic, not rollback.
Azure Policy
Why wrong: Azure Policy enforces compliance rules, not rollback.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Monitor
Option D is correct because Azure Monitor autoscale is not for rollback; you need to use a deployment strategy with health probes and maybe a tool like Azure Deployment Manager or progressive exposure in Azure DevOps. However, the most direct answer for automated rollback based on metrics is to configure a canary deployment with Azure App Configuration or use Azure DevOps release gates. The question asks for a service, and Azure Monitor can detect errors, but for automated rollback, you typically use Azure DevOps with monitoring. Among the options, Azure Monitor combined with Azure DevOps release gates is the best. But given the limited options, 'Azure Monitor' is the core service for error detection. The correct answer is 'Azure Monitor' because it provides the metrics that trigger the rollback. Option A is wrong because Azure Policy is for compliance. Option B is wrong because Azure Service Health is for Azure platform issues. Option C is wrong because Azure Traffic Manager is for DNS traffic routing.
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.
Azure Service Health
Why it's wrong here
Service Health notifies about Azure outages, not deployment errors.
Azure Monitor
Why this is correct
Azure Monitor can detect error rates and trigger alerts that can be used by Azure DevOps for rollback.

Azure Policy
Why it's wrong here
Azure Policy enforces compliance rules, not rollback.
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.
