Google Professional Cloud Developer Exam Practice Test Instant Access

Question 1

You are a developer at a large organization. Your team uses Git for source code management (SCM). You want to ensure that your team follows Google-recommended best practices to manage code to drive higher rates of software delivery. Which SCM process should your team use?

AEach group of developers creates a feature branch from the main branch for their work, commits their changes to their branch, and merges their code into the main branch before each major release.

BEach developer commits their code to the main branch before each product release, conducts testing, and rolls back if integration issues are detected.

CEach group of developers copies the repository, commits their changes to their repository, and merges their code into the main repository before each product release.

DEach developer creates a branch for their own work, commits their changes to their branch, and merges their code into the main branch after peer review.

Answer : D

CEach developer creates a branch for their own work, commits their changes to their branch, and merges their code into the main branch daily.

DEach group of developers creates a feature branch from the main branch for their work, commits their changes to their branch, and merges their code into the main branch after the change advisory board approves it.

Answer : D

Use a centralized repository. A centralized repository is a single location where all of your team's code is stored. This makes it easy for everyone to access the latest code, and it also helps to prevent conflicts. Use branches. Branches are a way to create a separate version of the code for development purposes. This allows developers to work on new features or bug fixes without affecting the main branch of the code.

Question 3

You are developing an event-driven application. You have created a topic to receive messages sent to Pub/Sub. You want those messages to be processed in real time. You need the application to be independent from any other system and only incur compute costs when new messages arrive. You want to configure the simplest and most efficient architecture What should you do?

ADeploy your code on Cloud Functions. Use a Pub/Sub trigger to invoke the Cloud Function. Use the Pub/Sub API to create a pull subscription to the Pub/Sub topic and read messages from it.

BDeploy your code on Cloud Functions. Use a Pub/Sub trigger to handle new messages in the topic.

CDeploy the application on Google Kubernetes Engine. Use the Pub/Sub API to create a pull subscription to the Pub/Sub topic and read messages from it

DDeploy the application on Compute Engine. Use a Pub/Sub push subscription to process new messages in the topic.

Question 4

You are deploying a Python application to Cloud Run using Cloud Build. The Cloud Build pipeline is shown below:

You want to optimize deployment times and avoid unnecessary steps What should you do?

ARemove the step that pushes the container to Artifact Registry.

BAdd the ---cache-from argument to the Docker build step in your build config file.

CStore image artifacts in a Cloud Storage bucket in the same region as the Cloud Run instance.

DDeploy a new Docker registry in a VPC and use Cloud Build worker pools inside the VPC to run the build pipeline.

Question 5

You have an ecommerce application hosted in Google Kubernetes Engine (GKE) that receives external requests and forwards them to third-party APIs external to Google Cloud. The third-party APIs are responsible for credit card processing, shipping, and inventory management using the process shown in the diagram.

Your customers are reporting that the ecommerce application is running slowly at unpredictable times. The application doesn't report any metrics You need to determine the cause of the inconsistent performance What should you do?

AInstall the Ops Agent inside your container and configure it to gather application metrics.

BInstall the OpenTelemetry library for your respective language, and instrument your application.

CModify your application to read and forward the x-Cloud-Trace-context header when it calls the
downstream services
D Enable Managed Service for Prometheus on the GKE cluster to gather application metrics.

Answer : B

Question 6

You are developing a new web application using Cloud Run and committing code to Cloud Source Repositories. You want to deploy new code in the most efficient way possible. You have already created a Cloud Build YAML file that builds a container and runs the following command: gcloud run deploy. What should you do next?

ACreate a Pub/Sub topic to be notified when code is pushed to the repository. Create a Pub/Sub trigger that runs the build file when an event is published to the topic.

BCreate a build trigger that runs the build file in response to a repository code being pushed to the development branch.

CCreate a webhook build trigger that runs the build file in response to HTTP POST calls to the webhook URL.

DCreate a Cron job that runs the following command every 24 hours: gcloud builds submit.

Answer : B

https://cloud.google.com/build/docs/triggers

Cloud Build uses build triggers to enable CI/CD automation. You can configure triggers to listen for incoming events, such as when a new commit is pushed to a repository or when a pull request is initiated, and then automatically execute a build when new events come in. You can also configure triggers to build code on any changes to your source repository or only on changes that match certain criteria.

Question 7

You are developing an application hosted on Google Cloud that uses a MySQL relational database schem

a. The application will have a large volume of reads and writes to the database and will require backups and ongoing capacity planning. Your team does not have time to fully manage the database but can take on small administrative tasks. How should you host the database?

AConfigure Cloud SQL to host the database, and import the schema into Cloud SQL.

BDeploy MySQL from the Google Cloud Marketplace to the database using a client, and import the schema.

CConfigure Bigtable to host the database, and import the data into Bigtable.

DConfigure Cloud Spanner to host the database, and import the schema into Cloud Spanner.

EConfigure Firestore to host the database, and import the data into Firestore.

Answer : A
