Question #6 (Topic: Single Topic)
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?
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?
A. Add logic to each Cloud Build step to HTTP POST the build information to a webhook.
B. Add a new step at the end of the pipeline in Cloud Build to HTTP POST the build information to a webhook.
C. Use Stackdriver Logging to create a logs-based metric from the Cloud Build logs. Create an Alert with a Webhook notification type.
D. Create a Cloud Pub/Sub push subscription to the Cloud Build cloud-builds PubSub topic to HTTP POST the build information to a webhook.
Answer: D
Question #7 (Topic: Single Topic)
You use Spinnaker to deploy your application and have created a canary deployment stage in the pipeline. Your application has an in-memory cache that loads
objects at start time. You want to automate the comparison of the canary version against the production version. How should you configure the canary analysis?
objects at start time. You want to automate the comparison of the canary version against the production version. How should you configure the canary analysis?
A. Compare the canary with a new deployment of the current production version.
B. Compare the canary with a new deployment of the previous production version.
C. Compare the canary with the existing deployment of the current production version.
D. Compare the canary with the average performance of a sliding window of previous production versions.
Answer: A
Question #8 (Topic: Single Topic)
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?
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?
A. Bucketize the request latencies into ranges, and then compute the percentile at 100 ms.
B. Bucketize the request latencies into ranges, and then compute the median and 90th percentiles.
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.
D. Count the number of home page request that load in under 100 ms, and then divide by the total number of all web application requests.
Answer: C
Question #9 (Topic: Single Topic)
You deploy a new release of an internal application during a weekend maintenance window when there is minimal user tragic. After the window ends, you learn
that one of the new features isn't working as expected in the production environment. After an extended outage, you roll back the new release and deploy a fix.
