Question 1 of 166

You support a Node.js application running on Google Kubernetes Engine (GKE) in production. The application makes several HTTP requests to dependent applications. You want to anticipate which dependent applications might cause performance issues. What should you do?

    Correct Answer: B

    To anticipate which dependent applications might cause performance issues in a Node.js application running on Google Kubernetes Engine (GKE) and making several HTTP requests, the best approach is to instrument all applications with Stackdriver Trace and review inter-service HTTP requests. Stackdriver Trace allows you to track the time taken by each service and identify bottlenecks, providing the most direct insight into performance issues related to HTTP requests among dependent applications.

Question 2 of 166

You created a Stackdriver chart for CPU utilization in a dashboard within your workspace project. You want to share the chart with your Site Reliability Engineering

(SRE) team only. You want to ensure you follow the principle of least privilege. What should you do?

    Correct Answer: C

    To grant the Site Reliability Engineering (SRE) team the least privilege necessary to view the specific Stackdriver chart for CPU utilization, you should use the 'Share chart by URL' feature and provide the URL to the SRE team. Additionally, assigning the SRE team the Monitoring Viewer IAM role in the workspace project will give them read-only access to the chart's data without granting them unnecessary permissions. This ensures they can view the chart without making configurations or accessing other data unrelated to their role.

Question 3 of 166

Your organization wants to implement Site Reliability Engineering (SRE) culture and principles. Recently, a service that you support had a limited outage. A manager on another team asks you to provide a formal explanation of what happened so they can action remediations. What should you do?

    Correct Answer: B

    In Site Reliability Engineering (SRE) practices, transparency and shared learning are key components. Developing a postmortem that includes the root causes, resolution, lessons learned, and a prioritized list of action items, and then sharing it on the engineering organization's document portal ensures that the information is accessible to the broader team. This approach promotes a culture of continuous improvement and helps prevent similar issues in the future. By making postmortems widely available, organizations can learn from past incidents and improve their reliability practices as a whole.

Question 4 of 166

You have a set of applications running on a Google Kubernetes Engine (GKE) cluster, and you are using Stackdriver Kubernetes Engine Monitoring. You are bringing a new containerized application required by your company into production. This application is written by a third party and cannot be modified or reconfigured. The application writes its log information to /var/log/app_messages.log, and you want to send these log entries to Stackdriver Logging. What should you do?

    Correct Answer: B

    To send log entries from the application to Stackdriver Logging, deploying a Fluentd daemonset to GKE is the appropriate solution. Fluentd is a highly customizable logging agent that can be configured to collect logs from specific files within your application's pods, including logs not written to standard output (stdout) or standard error (stderr). In this case, you can create a customized input configuration for Fluentd to tail the /var/log/app_messages.log file and an output configuration to forward these logs to Stackdriver Logging. This approach allows you to handle the log files without modifying the application, which is a necessary constraint.

Question 5 of 166

You are running an application in a virtual machine (VM) using a custom Debian image. The image has the Stackdriver Logging agent installed. The VM has the cloud-platform scope. The application is logging information via syslog. You want to use Stackdriver Logging in the Google Cloud Platform Console to visualize the logs. You notice that syslog is not showing up in the "All logs" dropdown list of the Logs Viewer. What is the first thing you should do?

    Correct Answer: D

    You should SSH to the VM and execute the commands to check if the agent is running. The first step in troubleshooting why the syslog is not appearing in the Logs Viewer is to confirm that the Stackdriver Logging agent (fluentd) is operational. If the agent isn’t running, it won’t be able to collect and send logs to Stackdriver. Therefore, confirming the agent’s status should be the initial action to take.
