Google's Professional Cloud Developer You have an application that uses an HTTP Cloud Function to process user activity from both desktop browser and mobile application clients. This function will serve as the endpoint for all metric submissions using HTTP POST.Due to legacy restrictions, the function must be mapped to a domain that is separate from the domain requested by users on web or mobile sessions. The domain for the Cloud Function is https://fn.example.com. Desktop and mobile clients use the domain https://www.example.com. You need to add a header to the function'sHTTP response so that only those browser and mobile sessions can submit metrics to the Cloud Function. Which response header should you add?

Google's Professional Cloud Developer You have an HTTP Cloud Function that is called via POST. Each submission's request body has a flat, unnested JSON structure containing numeric and text data. After the Cloud Function completes, the collected data should be immediately available for ongoing and complex analytics by many users in parallel. How should you persist the submissions?

What should you do?

Google's Professional Cloud Developer Your company needs a database solution that stores customer purchase history and meets the following requirements:✑ Customers can query their purchase immediately after submission.✑ Purchases can be sorted on a variety of fields.✑ Distinct record formats can be stored at the same time.Which storage option satisfies these requirements?

Google's Professional Cloud Developer You recently developed a new service on Cloud Run. The new service authenticates using a custom service and then writes transactional information to a CloudSpanner database. You need to verify that your application can support up to 5,000 read and 1,000 write transactions per second while identifying any bottlenecks that occur. Your test infrastructure must be able to autoscale. What should you do?

Google's Professional Cloud Developer You are using Cloud Build for your CI/CD pipeline to complete several tasks, including copying certain files to Compute Engine virtual machines. Your pipeline requires a flat file that is generated in one builder in the pipeline to be accessible by subsequent builders in the same pipeline. How should you store the file so that all the builders in the pipeline can access it?

Google's Professional Cloud Developer Your company’s development teams want to use various open source operating systems in their Docker builds. When images are created in published containers in your company’s environment, you need to scan them for Common Vulnerabilities and Exposures (CVEs). The scanning process must not impact software development agility. You want to use managed services where possible. What should you do?

Google's Professional Cloud Developer You are configuring a continuous integration pipeline using Cloud Build to automate the deployment of new container images to Google Kubernetes Engine (GKE). The pipeline builds the application from its source code, runs unit and integration tests in separate steps, and pushes the container to Container Registry. The application runs on a Python web server.The Dockerfile is as follows:FROM python:3.7-alpine -COPY . /app -WORKDIR /app -RUN pip install -r requirements.txtCMD [ "gunicorn", "-w 4", "main:app" ]You notice that Cloud Build runs are taking longer than expected to complete. You want to decrease the build time. What should you do? (Choose two.) E. Store application source code on Cloud Storage, and configure the pipeline to use gsutil to download the source code.

Google's Professional Cloud Developer You are building a CI/CD pipeline that consists of a version control system, Cloud Build, and Container Registry. Each time a new tag is pushed to the repository, a Cloud Build job is triggered, which runs unit tests on the new code builds a new Docker container image, and pushes it into Container Registry. The last step of your pipeline should deploy the new container to your production Google Kubernetes Engine (GKE) cluster. You need to select a tool and deployment strategy that meets the following requirements:• Zero downtime is incurred• Testing is fully automated• Allows for testing before being rolled out to users• Can quickly rollback if neededWhat should you do?
