Question 940
A production VM encounters sustained disk latency, yet dashboards omit guest metrics and process-level context. Choose TWO measures that implement and verify an effective Azure DevOps response to this specific situation. (Choose TWO.)
- Bypass review and testing for azure vm insights memory disk and process telemetry whenever the release deadline is urgent, applying the change to production immediately.
- Dismiss the known risk for azure vm insights memory disk and process telemetry and keep no evidence or accountable owner after deployment.
- Declare azure vm insights memory disk and process telemetry successful solely from a green pipeline status and skip checking its actual control outcome.
- Configure Azure VM Insights or suitable agent-based data collection for memory, disk, process, and guest metrics.
- Create a controlled resource threshold and verify the matching guest metric, alert, and operating-system log event.
Explanation
Correct Answers
D:Configure Azure VM Insights or suitable agent-based data collection for memory, disk, process, and guest metrics. Host and guest measurements differ; default platform telemetry may not expose the failing application resource. Missing memory or storage insight can prolong outages despite apparently normal CPU utilization.
E:Create a controlled resource threshold and verify the matching guest metric, alert, and operating-system log event. Host and guest measurements differ; default platform telemetry may not expose the failing application resource.
Incorrect Answers
A:Bypass review and testing for azure vm insights memory disk and process telemetry whenever the release deadline is urgent, applying the change to production immediately. It conflicts with the stated operating condition: Host and guest measurements differ; default platform telemetry may not expose the failing application resource.
B:Dismiss the known risk for azure vm insights memory disk and process telemetry and keep no evidence or accountable owner after deployment. It conflicts with the stated operating condition: Host and guest measurements differ; default platform telemetry may not expose the failing application resource.
C:Declare azure vm insights memory disk and process telemetry successful solely from a green pipeline status and skip checking its actual control outcome. It conflicts with the stated operating condition: Host and guest measurements differ; default platform telemetry may not expose the failing application resource.
Question 941
A release fails while uploading artifacts to Blob Storage, but the team sees only pipeline job errors without storage request codes. Which implementation BEST addresses the operational issue?
- Configure Azure VM Insights or suitable agent-based data collection for memory, disk, process, and guest metrics.
- Enable relevant Azure Storage, network, and private-endpoint diagnostics with actionable request and dependency metrics.
- Configure Azure Monitor diagnostic settings and workspace routing for critical DevOps workloads and relevant resource metrics.
- Enable appropriate Azure Monitor Container Insights collection and alerts for nodes, pods, restarts, and utilization.
Explanation
Correct Answer
B:Enable relevant Azure Storage, network, and private-endpoint diagnostics with actionable request and dependency metrics. Deployment failures may come from storage and network dependencies even when the build itself is correct. Blind spots in service dependencies can cause repeated job retries without identifying root cause.
Incorrect Answers
A:Configure Azure VM Insights or suitable agent-based data collection for memory, disk, process, and guest metrics. That applies to azure vm insights memory disk and process telemetry, not azure storage and network diagnostics for deployment troubleshooting.
C:Configure Azure Monitor diagnostic settings and workspace routing for critical DevOps workloads and relevant resource metrics. That applies to azure monitor platform metrics and log analytics integration, not azure storage and network diagnostics for deployment troubleshooting.
D:Enable appropriate Azure Monitor Container Insights collection and alerts for nodes, pods, restarts, and utilization. That applies to azure container insights for aks node and pod reliability, not azure storage and network diagnostics for deployment troubleshooting.
Question 942
A release fails while uploading artifacts to Blob Storage, but the team sees only pipeline job errors without storage request codes. How should the team validate the intended result?
- Trigger a controlled pod failure in staging and verify restart, node, and container metrics and logs are correlated.
- Follow a test request through dependency timings, exceptions, and correlated operation IDs in telemetry.
- Reproduce an authorized failed request and correlate status code, endpoint resolution, and network telemetry.
- Trigger a controlled failed workflow and verify alert delivery, affected branch, job identity, and owner acknowledgment.
Explanation
Correct Answer
C:Reproduce an authorized failed request and correlate status code, endpoint resolution, and network telemetry. Deployment failures may come from storage and network dependencies even when the build itself is correct.
Incorrect Answers
A:Trigger a controlled pod failure in staging and verify restart, node, and container metrics and logs are correlated. That applies to azure container insights for aks node and pod reliability, not azure storage and network diagnostics for deployment troubleshooting.
B:Follow a test request through dependency timings, exceptions, and correlated operation IDs in telemetry. That applies to application insights request correlation and distributed tracing, not azure storage and network diagnostics for deployment troubleshooting.
D:Trigger a controlled failed workflow and verify alert delivery, affected branch, job identity, and owner acknowledgment. That applies to github actions run health and workflow failure alerts, not azure storage and network diagnostics for deployment troubleshooting.
Question 943
A release fails while uploading artifacts to Blob Storage, but the team sees only pipeline job errors without storage request codes. What is the underlying reason the existing approach fails?
- Aggregate request totals cannot identify which distributed dependency is responsible for slow or failing transactions.
- Host and guest measurements differ; default platform telemetry may not expose the failing application resource.
- Deployment failures may come from storage and network dependencies even when the build itself is correct.
- CI reliability is an operational service and must surface broken or stalled workflows to accountable responders.
Explanation
Correct Answer
C:Deployment failures may come from storage and network dependencies even when the build itself is correct. Blind spots in service dependencies can cause repeated job retries without identifying root cause.
Incorrect Answers
A:Aggregate request totals cannot identify which distributed dependency is responsible for slow or failing transactions. That applies to application insights request correlation and distributed tracing, not controlling principle for azure storage and network diagnostics for deployment troubleshooting.
B:Host and guest measurements differ; default platform telemetry may not expose the failing application resource. That applies to azure vm insights memory disk and process telemetry, not controlling principle for azure storage and network diagnostics for deployment troubleshooting.
D:CI reliability is an operational service and must surface broken or stalled workflows to accountable responders. That applies to github actions run health and workflow failure alerts, not controlling principle for azure storage and network diagnostics for deployment troubleshooting.
Question 944
A release fails while uploading artifacts to Blob Storage, but the team sees only pipeline job errors without storage request codes. Which recurring control most directly sustains the required behavior?
- Retain relevant diagnostic categories and alert on sustained authentication or connectivity failures.
- Monitor agent health and keep data-collection rules aligned with current VM image versions.
- Maintain diagnostic policy coverage and review missing telemetry as subscriptions and environments expand.
- Review agent collection health and resource dimensions when clusters and workloads are upgraded.
Explanation
Correct Answer
A:Retain relevant diagnostic categories and alert on sustained authentication or connectivity failures. Blind spots in service dependencies can cause repeated job retries without identifying root cause.
Incorrect Answers
B:Monitor agent health and keep data-collection rules aligned with current VM image versions. This helps sustain a control for azure vm insights memory disk and process telemetry; it does not directly stop recurrence of azure storage and network diagnostics for deployment troubleshooting described in this case.
C:Maintain diagnostic policy coverage and review missing telemetry as subscriptions and environments expand. This helps sustain a control for azure monitor platform metrics and log analytics integration; it does not directly stop recurrence of azure storage and network diagnostics for deployment troubleshooting described in this case.
D:Review agent collection health and resource dimensions when clusters and workloads are upgraded. This helps sustain a control for azure container insights for aks node and pod reliability; it does not directly stop recurrence of azure storage and network diagnostics for deployment troubleshooting described in this case.
Question 945
A release fails while uploading artifacts to Blob Storage, but the team sees only pipeline job errors without storage request codes. What is the MOST important consequence if this issue remains unresolved?
- A cluster can appear healthy at the VM level while customer applications repeatedly fail.
- Important production failures may be hidden when expected log and metric streams were never enabled.
- Investigators may repair the wrong service when requests cannot be traced across boundaries.
- Blind spots in service dependencies can cause repeated job retries without identifying root cause.
Explanation
Correct Answer
D:Blind spots in service dependencies can cause repeated job retries without identifying root cause. This is the directly relevant business or security consequence of azure storage and network diagnostics for deployment troubleshooting. Root cause: Deployment failures may come from storage and network dependencies even when the build itself is correct.
