Free Google Professional-Cloud-DevOps-Engineer Exam Questions

Question 1

You have an application running in Google Kubernetes Engine. The application invokes multiple services per request but responds too slowly. You need to identify which downstream service or services are causing the delay. What should you do?

A : Analyze VPC flow logs along the path of the request.

B : Investigate the Liveness and Readiness probes for each service.

C : Create a Dataflow pipeline to analyze service metrics in real time

D : Use a distributed tracing framework such as OpenTelemetry or Stackdriver Trace.

Answer: C

Question 2

You are designing a system with three different environments: development, quality assurance (QA), and production. Each environment will be deployed with Terraform and has a Google Kubernetes Engine Enterprise (GKE Enterprise) cluster created so that application teams can deploy their applications. Config Sync will be used and templated to deploy infrastructure-level resources in each GKE Enterprise cluster. All users (for example, infrastructure operators and application owners) will use GitOps. How should you structure your source control repositories for both infrastructure as code (IaC) and application code?

A : Cloud Infrastructure (Terraform) repository is shared: different directories are different environments GKE Enterprise Infrastructure (Config Sync Kustomize manifests) repository is shared: different overlay directories are different environments Application (app source code) repositories are separated: different branches are different features

B : Cloud Infrastructure (Terraform) repository is shared: different directories are different environments GKE Enterprise Infrastructure (Config Sync Kustomize manifests) repositories are separated: different branches are different environments Application (app source code) repositories are separated: different branches are different features

C : Cloud Infrastructure (Terraform) repository is shared: different branches are different environments GKE Enterprise Infrastructure (Config Sync Kustomize manifests) repository is shared: different overlay directories are different environments Application (app source code) repository is shared: different directories are different features

D : Cloud Infrastructure (Terraform) repositories are separated: different branches are different environments GKE Enterprise Infrastructure (Config Sync Kustomize manifests) repositories are separated: different overlay directories are different environments Application (app source code) repositories are separated: different branches are different features

Answer: A

Question 3

What are some of the aspects involved in assessing the impact of an event in incident management?

A : The specific time of day the event occurred

B : The number of follow-up action items required

C : The number of teams involved in resolving the issue

D : The nature of the event, impact to end users, impact to the business, dependent stakeholders at risk, and financial loss to the business

Answer: D

D : Cloud Infrastructure (Terraform) repositories are separated: different branches are different environments GKE Enterprise Infrastructure (Config Sync Kustomize manifests) repositories are separated: different overlay directories are different environments Application (app source code) repositories are separated: different branches are different features

Answer: A

Question 5

You work for a company that manages highly sensitive user data. You are designing the Google Kubernetes Engine (GKE) infrastructure for your company, including several applications that will be deployed in development and production environments. Your design must protect data from unauthorized access from other applications while minimizing the amount of management overhead required. What should you do?

A : Create one cluster for the organization with separate namespaces for each application and environment combination.

B : Create one cluster for each environment (development and production) with each application in its own namespace within each cluster.

C : Create one cluster for the organization with separate namespaces for each application.

D : Create one cluster for each application with separate namespaces for production and development environments.

Answer: B
