Cisco Exam 300-910 Topic 17 Question 98 Discussion

Actual exam question for Cisco's 300-910 exam

Question #: 98
Topic #: 17

A DevOps engineer is supporting a containerized application with multiple components running across the Kubernetes cluster. Metrics from the container (CPU and memory) and application (requests per second and heap size) are being collected by Prometheus and displayed with Grafan

a. Users report transaction timeout problems with the application, but the metric graphs all look within normal levels.

Which type of failure would prevent the engineer from seeing the problem using the captured metrics?

AGrafana has lost connectivity to Prometheus, which causes graphs to display only the cached data.

BCPU and memory metrics from Kubernetes nodes are not accurate due to the way that containers share resources.

CSome containers are crashing regularly and being restarted automatically by Kubernetes.

DThe metricbeat agent has crashed and is no longer sending new data to Prometheus, so the metrics are not updating.

The issue is likely due to some containers crashing and being restarted automatically by Kubernetes. This would prevent the captured metrics from accurately reflecting the real-time performance of the application.
