AZ-400 Monitoring, Feedback & Security 3

Question 1

Which Azure Monitor feature lets you group related alerts into a single notification to reduce alert fatigue during an incident?

Accepted Answer

Smart alert grouping (alert correlation)

Answer

Smart alert grouping in Azure Monitor correlates fired alerts that are likely related into a single incident, reducing notification noise.

Question 2

Your pipeline must enforce that only signed container images are deployed to AKS. Which Kubernetes admission mechanism combined with Azure Policy achieves this?

Accepted Answer

Azure Policy for AKS using the image signature verification constraint

Answer

Azure Policy for AKS supports image integrity policies that verify image signatures (via Notation/Ratify) before allowing pods to start.

Question 3

A developer wants to see real-time telemetry while debugging a locally running service instrumented with Application Insights. Which feature streams live data?

Accepted Answer

Live Metrics Stream

Answer

Live Metrics Stream in Application Insights provides near-real-time telemetry (within 1 second) from a running application for immediate feedback.

Question 4

You need to ensure that Azure DevOps pipeline artifacts are not tampered with between stages. Which practice best addresses this supply chain security concern?

Accepted Answer

Sign artifacts with a code-signing certificate and verify the signature in downstream stages

Answer

Signing pipeline artifacts and verifying signatures in downstream stages ensures integrity and detects tampering across pipeline stages.

Question 5

Your SRE team wants to set an error budget based on a 99.9% SLO for an API. Which Application Insights query approach helps track budget burn rate?

Accepted Answer

Write a KQL query calculating the ratio of failed requests to total requests over a rolling window

Answer

A KQL query that computes failed/total request ratio over a rolling window directly measures SLO compliance and error budget consumption.
