You use a multiple step Cloud Build pipeline to build and deploy your application to Google Kubernetes Engine (GKE). You want to integrate with a third-party monitoring platform by performing a HTTP POST of the build information to a webhook. You want to minimize the development effort. What should you do?

1. A. Add logic to each Cloud Build step to HTTP POST the build information to a webhook.
2. B. Add a new step at the end of the pipeline in Cloud Build to HTTP POST the build information to a webhook.
3. C. Use Stackdriver Logging to create a logs-based metric from the Cloud Buitd log
4. D. Create an Alert with a Webhook notification type.
5. E. Create a Cloud Pub/Sub push subscription to the Cloud Build cloud-builds PubSub topic to HTTP POST the build information to a webhook.

Correct Answer: D

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?

1. A. Instrument all applications with Stackdriver Profiler.
2. B. Instrument all applications with Stackdriver Trace and review inter-service HTTP requests.
3. C. Use Stackdriver Debugger to review the execution of logic within each application to instrument all applications.
4. D. Modify the Node.js application to log HTTP request and response times to dependent application
5. E. Use Stackdriver Logging to find dependent applications that are performing poorly.

Correct Answer: B

You are managing the production deployment to a set of Google Kubernetes Engine (GKE) clusters. You want to make sure only images which are successfully built by your trusted CI/CD pipeline are deployed to production. What should you do?

1. A. Enable Cloud Security Scanner on the clusters.
2. B. Enable Vulnerability Analysis on the Container Registry.
3. C. Set up the Kubernetes Engine clusters as private clusters.
4. D. Set up the Kubernetes Engine clusters with Binary Authorization.

You support a high-traffic web application and want to ensure that the home page loads in a timely manner. As a first step, you decide to implement a Service Level Indicator (SLI) to represent home page request latency with an acceptable page load time set to 100 ms. What is the Google-recommended way of calculating this SLI?

1. A. Buckelize Ihe request latencies into ranges, and then compute the percentile at 100 ms.
2. B. Bucketize the request latencies into ranges, and then compute the median and 90th percentiles.
3. C. Count the number of home page requests that load in under 100 ms, and then divide by the total number of home page requests.
4. D. Count the number of home page requests that load in under 100 m
5. E. and then divide by the total number of all web application requests.

Correct Answer: C

In the SRE principles book, it's recommended treating the SLI as the ratio of two numbers: the number of good events divided by the total number of events. For example: Number of successful HTTP requests / total HTTP requests (success rate)

You are responsible for creating and modifying the Terraform templates that define your Infrastructure. Because two new engineers will also be working on the same code, you need to define a process and adopt a tool that will prevent you from overwriting each other's code. You also want to ensure that you capture all updates in the latest version. What should you do?

1. A. • Store your code in a Git-based version control system.• Establish a process that allows developers to merge their own changes at the end of each day.• Package and upload code lo a versioned Cloud Storage bucket as the latest master version.
2. B. • Store your code in a Git-based version control system.• Establish a process that includes code reviews by peers and unit testing to ensure integrity and functionality before integration of code.• Establish a process where the fully integrated code in the repository becomes the latest master version.
3. C. • Store your code as text files in Google Drive in a defined folder structure that organizes the files.• At the end of each da
4. D. confirm that all changes have been captured in the files within the folder structure.• Rename the folder structure with a predefined naming convention that increments the version.
5. E. • Store your code as text files in Google Drive in a defined folder structure that organizes the files.• At the end of each day, confirm that all changes have been captured in the files within the folder structure and create a new .zip archive with a predefined naming convention.• Upload the .zip archive to a versioned Cloud Storage bucket and accept it as the latest version.

Correct Answer: B
