uptime and monitoring will not stop outages in application, howver you will be informed on time to respond to the issue. A. Configuring liveness and readiness probe in each pod will stop starting pods from receiving traffic before they are declared ready and available. hence before taking down a working pod.

why not A ? * Configuring liveness and readiness probes in the Pod specification is important to detect when a container in a Pod becomes unresponsive or starts experiencing problems. However, it does not directly prevent outages caused by misconfigurations with parameters that are only used in production. Liveness and readiness probes can help to detect issues with the application, but they do not provide information about the health of the underlying infrastructure. Misconfigurations with parameters that are only used in production can cause problems with the infrastructure itself, which may not be detected by liveness and readiness probes. In summary, while configuring liveness and readiness probes is important, it should be done in addition to other preventive measures such as configuring an uptime alert in Cloud Monitoring to ensure timely detection of outages and reduce their impact on the application.

Option B: Configuring health checks on the managed instance group is not relevant in this scenario, as the application is running in a GKE cluster, not on a managed instance group. Option C: Creating a Scheduled Task to check whether the application is available may help to detect outages, but it will not prevent them from occurring. To prevent outages, you should focus on identifying and addressing the root cause of the problem. Option D: Configuring an uptime alert in Cloud Monitoring may help to detect outages, but it will not prevent them from occurring. To prevent outages, you should focus on identifying and addressing the root cause of the problem.
