When static routes are added to a router in a network using a CI/CD pipeline, an Ansible playbook is used to make these changes. Which steps must be added to the pipeline to validate that the changes have the intended effect on the traffic flow?

Add a step to run the debug ip routing command before the change, and add a step after the change to issue the no debug ip routing command.
Add a step to capture the routing table before the change, and add a step after the change to capture it again. Calculate the difference between the two for review.
Add a step to ping a host on each of the static routes before the change, and a step after to repeat the same check. Calculate the difference between the two checks for review.
Add a step to run the same playbook again with the debug option enabled and use grep on the log output to ensure that the commands are not applied again.

QUESTION: 39

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:

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?
Grafana has lost connectivity to Prometheus, which causes graphs to display only the cached data.
CPU and memory metrics from Kubernetes nodes are not accurate due to the way that containers share resources.
Some containers are crashing regularly and being restarted automatically by Kubernetes.
The metricbeat agent has crashed and is no longer sending new data to Prometheus, so the metrics are not updating.
