Google Cloud Certified - Professional Cloud DevOps Engineer Exam Questions and Answers

Question 9

You support a web application that is hosted on Compute Engine. The application provides a booking service for thousands of users. Shortly after the release of a new feature, your monitoring dashboard shows that all users are experiencing latency at login. You want to mitigate the impact of the incident on the users of your service. What should you do first?

Options:

A.

Roll back the recent release.

B.

Review the Stackdriver monitoring.

C.

Upsize the virtual machines running the login services.

D.

Deploy a new release to see whether it fixes the problem.

Question 10

You are managing an application that exposes an HTTP endpoint without using a load balancer. The latency of the HTTP responses is important for the user experience. You want to understand what HTTP latencies all of your users are experiencing. You use Stackdriver Monitoring. What should you do?

Options:

A.

• In your application, create a metric with a metricKind set to DELTA and a valueType set to DOUBLE.• In Stackdriver's Metrics Explorer, use a Slacked Bar graph to visualize the metric.

B.

• In your application, create a metric with a metricKind set to CUMULATIVE and a valueType set to DOUBLE.• In Stackdriver's Metrics Explorer, use a Line graph to visualize the metric.

C.

• In your application, create a metric with a metricKind set to gauge and a valueType set to distribution.• In Stackdriver's Metrics Explorer, use a Heatmap graph to visualize the metric.

D.

• In your application, create a metric with a metricKind. set toMETRlc_KIND_UNSPECIFIEDanda valueType set to INT64.• In Stackdriver's Metrics Explorer, use a Stacked Area graph to visualize the metric.

Question 11

You need to define Service Level Objectives (SLOs) for a high-traffic multi-region web application. Customers expect the application to always be available and have fast response times. Customers are currently happy with the application performance and availability. Based on current measurement, you observe that the 90th percentile of latency is 120ms and the 95th percentile of latency is 275ms over a 28-day window. What latency SLO would you recommend to the team to publish?

Options:

A.

90th percentile – 100ms95th percentile – 250ms

B.

90th percentile – 120ms95th percentile – 275ms

C.

90th percentile – 150ms95th percentile – 300ms

D.

90th percentile – 250ms95th percentile – 400ms

Question 12

Your team deploys applications to three Google Kubernetes Engine (GKE) environments development staging and production You use GitHub reposrtones as your source of truth You need to ensure that the three environments are consistent You want to follow Google-recommended practices to enforce and install network policies and a logging DaemonSet on all the GKE clusters in those environments What should you do?

Options:

A.

Use Google Cloud Deploy to deploy the network policies and the DaemonSet Use Cloud Monitoring to trigger an alert if the network policies and DaemonSet drift from your source in the repository.

B.

Use Google Cloud Deploy to deploy the DaemonSet and use Policy Controller to configure the network policies Use Cloud Monitoring to detect drifts from the source in the repository and Cloud Functions tocorrect the drifts

C.

Use Cloud Build to render and deploy the network policies and the DaemonSet Set up Config Sync to sync the configurations for the three environments

D.

Use Cloud Build to render and deploy the network policies and the DaemonSet Set up a Policy Controller to enforce the configurations for the three environments
