Free Google Professional-Cloud-Developer Exam Questions

Question 1

Your team has created an application that is hosted on a Google Kubernetes Engine (GKE) cluster. You need to connect the application to a legacy REST service that is deployed in two GKE clusters in two different regions. You want to connect your application to the target service in a way that is resilient. You also want to be able to run health checks on the legacy service on a separate port. How should you set up the connection? (Choose two.)

A : Traffic Director with a sidecar proxy to connect the application to the service.

B : a proxyless Traffic Director configuration to connect the application to the service.

C : nfigure the legacy service's firewall to allow health checks originating from the proxy.

D : nfigure the legacy service's firewall to allow health checks originating from the application.

E : nfigure the legacy service's firewall to allow health checks originating from the Traffic Director control plane.

Answer: A,C

Question 2

Azgomi is a community application that facilitates communication between people in close proximity, used for event planning and organizing sporting events, and for businesses to connect with their local communities. Azgomi's unique style of hyper-local community communication and business outreach is in demand around the world. The executive statement is to expand the number one local community app globally. The solution concept is to expand their existing service in new regions to better serve their global customers, and hire and train a new team to support these regions in their time zones. Azgomi wants to ensure the application scales smoothly and provides clear uptime data, and that they analyze and respond to any issues that occur. Their existing technical environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform.

Azgomi's investors want to expand their footprint and support the increase in demand they are seeing. They require the application to expand availability to new regions, support 10x as many concurrent users, ensure a consistent experience for users when they travel to different regions, obtain user activity metrics to better monetize their product, ensure compliance with regulations in new regions, reduce infrastructure management time and cost, and adopt Google-recommended practices for cloud computing. The technical requirements include providing secure communications between the on-premises data center and cloud-hosted applications and infrastructure, providing usage metrics and monitoring, requiring authentication and authorization for APIs, implementing faster and more accurate validation of new features, providing actionable information for logging and performance metrics, and scaling to meet user demand.

A recent security audit discovered that Azgomi's database credentials for their Compute Engine-hosted MySQL databases are stored in plain text on persistent disks. Azgomi needs to reduce the risk of these credentials being stolen.

What actions do you suggest for them?

A : Create a service account and download its key. Use it to authenticate to Cloud KMS for database credentials.

B : Create a service account and use its key to authenticate to Cloud KMS for a decryption key to access the database credentials.

C : Create a service account and give it the roles/iam.serviceAccountUser role. Authenticate using Cloud SQL Proxy while impersonating this account.

D : Grant the roles/secretmanager.secretAccessor role to the Compute Engine service account and use Secret Manager API to store and access the database credentials.

Answer: C

Question 3

Your team detected a spike of errors in an application running on Cloud Run in your production project. The application is configured to read messages from Pub/Sub topic A, process the messages, and write the messages to topic B. You want to conduct tests to identify the cause of the errors. You can use a set of mock messages for testing. What should you do?

A : ploy the Pub/Sub and Cloud Run emulators on your local machine. Deploy the application locally, and change the logging level in the application to DEBUG or INFO. Write mock messages to topic A, and then analyze the logs.

B : the gcloud CLI to write mock messages to topic A. Change the logging level in the application to DEBUG or INFO, and then analyze the logs.

C : ploy the Pub/Sub emulator on your local machine. Point the production application to your local Pub/Sub topics. Write mock messages to topic A, and then analyze the logs.

D : the Google Cloud console to write mock messages to topic A. Change the logging level in the application to DEBUG or INFO, and then analyze the logs.

Answer: C

Question 4

A stateless web application for a marquee is being developed for Google Cloud. It is expected that the incoming user traffic will be unpredictable, with some days having no traffic while other days will have large spikes. The application should be able to automatically scale up and down, while minimizing the cost associated with running the application.

What actions do you need to take?

A : Use Python and Firestore to build the application, then deploy it to a managed instance group with autoscaling on Compute Engine.

B : Create the application with C# and Firestore, and deploy it to App Engine's flexible environment.

C : Build the application using Python and Firestore, then deploy it to Cloud Run.

D : Develop the application with Python and CloudSQL, and deploy it to App Engine's standard environment.

Answer: C

Question 5

You are supporting a business-critical application in production deployed on Cloud Run. The application is reporting HTTP 500 errors that are affecting the usability of the application. You want to be alerted when the number of errors exceeds 15% of the requests within a specific time window. What should you do?

A : eate a Cloud Function that consumes the Cloud Monitoring API. Use Cloud Scheduler to trigger the Cloud Function daily and alert you if the number of errors is above the defined threshold

B : vigate to the Cloud Run page in the Google Cloud console, and select the service from the services list. Use the Metrics tab to visualize the number of errors for that revision, and refresh the page daily.

C : eate an alerting policy in Cloud Monitoring that alerts you if the number of errors is above the defined threshold.

D : eate a Cloud Function that consumes the Cloud Monitoring API. Use Cloud Composer to trigger the Cloud Function daily and alert you if the number of errors is above the defined threshold.

Answer: C
