The service will need to scale as quickly as possible to respond to changing load. What should you do?

• A. Use a Horizontal Pod Autoscaler to scale the containers, and expose them via a ClusterIP Service.
• B. Use a Vertical Pod Autoscaler to scale the containers, and expose them via a ClusterIP Service.
• C. Use a Vertical Pod Autoscaler to scale the containers, and expose them via a NodePort Service.
• D. Use a Horizontal Pod Autoscaler to scale the containers, and expose them via a NodePort Service.

Your company has a successful multi-player game that has become popular in the US. Now, it wants to expand to other regions. It is launching a new feature that allows users to trade points.
This feature will work for users across the globe. Your company's current MySQL backend is reaching the limit of the Compute Engine instance that hosts the game. Your company wants to migrate to a different database that will provide global consistency and high availability across the regions. Which database should they choose?

• A. Cloud SQL
• B. BigQuery
• C. Cloud Spanner
• D. Cloud Bigtable

You are responsible for improving the security of your Cloud Run services to protect these services against supply chain threats. You need to ensure that there are adequate security controls such as SLSA Level 3 builds for container images and non-falsifiable provenance for container images by using Google Cloud tools. What should you do?

• A. Use Cloud Build to build container images. Configure a Binary Authorization policy on the Cloud Run job.
• B. Use Cloud Build to build container images. Use Cloud Scheduler to automate delivery of your applications to a series of target environments in a defined sequence.
• C. Ask developers to build container images locally and ensure strict version controls by using Container Registry.
• D. Use Cloud Deploy to generate authenticated and non-falsifiable build provenance for container images.

You are using Cloud Run to host a global ecommerce web application. Your company's design team is creating a new color scheme for the web app. You have been tasked with determining whether the new color scheme will increase sales. You want to conduct testing on live production traffic. How should you design the study?

• A. Use an external HTTP(S) load balancer to route traffic to the original color scheme while the new deployment is created and tested. After testing is complete, reroute all traffic to the new color scheme. Analyze the results to determine whether there is a statistically significant difference in sales.
• B. Use an external HTTP(S) load balancer to mirror traffic to the new version of your application.
  Analyze the results to determine whether there is a statistically significant difference in sales.
• C. Enable a feature flag that displays the new color scheme to half of all users. Monitor sales to see whether they increase for this group of users.
• D. Use an external HTTP(S) load balancer to route a predetermined percentage of traffic to two different color schemes of your application. Analyze the results to determine whether there is a statistically significant difference in sales.

You developed a Python script that retrieves information from files that are uploaded to Cloud Storage and writes the information to Bigtable. You have completed testing on your local environment and created the python-script service account with the Bigtable User IAM role. You want to deploy the code with the appropriate authentication while following Google-recommended practices. What should you do?

• A. 1. Deploy your code to Cloud Run functions. Create a Cloud Storage trigger.
  2. Create a service account key for authentication
• B. 1. Deploy your code to Cloud Run functions. Create a Cloud Storage trigger.
  2. Configure IAM binding for authentication.
• C. 1. Deploy your image to Cloud Run. Create a trigger in Cloud Scheduler that triggers the service every minute.
  2. Create a service account key for authentication.
• D. 1. Deploy your image to Cloud Run. Create a trigger in Cloud Scheduler that triggers the service every minute.
  2. Configure IAM binding for authentication.
