Exam Professional-Cloud-Architect Topic 4 Question 175 Discussion

Actual exam question for Google's Professional-Cloud-Architect exam
Question #: 175
Topic #: 4

Your company has an application running as a Deployment in a Google Kubernetes Engine (GKE) cluster When releasing new versions of the application via a rolling deployment, the team has been causing outages The root cause of the outages is misconfigurations with parameters that are only used in production You want to put preventive measures for this in the platform to prevent outages What should you do?

A. Configure liveness and readiness probes in the Pod specification B. Configure an uptime alert in Cloud Monitoring C. Create a Scheduled Task to check whether the application is available D. Configure health checks on the managed instance group

Suggested Answer: D Vote an answer

This option can help prevent outages caused by misconfigurations with parameters that are only used in production. Liveness and readiness probes are mechanisms to check the health and availability of the Pods and containers in a GKE cluster. Liveness probes determine if a container is still running, and if not, restart it.
Readiness probes determine if a container is ready to serve requests, and if not, remove it from the load balancer. By configuring liveness and readiness probes in the Pod specification, you can ensure that your application can handle traffic and recover from failures gracefully during a rolling update. The other options are not optimal for this scenario, because they either do not prevent outages, but only alert or monitor them (B, C), or do not apply to GKE clusters, but to Compute Engine instances (D).
