For this question, refer to the TerramEarth case study.
TerramEarth has equipped unconnected trucks with servers and sensors to collet telemetry dat a. Next year they want to use the data to train machine learning models. They want to store this data in the cloud while reducing costs. What should they do?

• A.Have the vehicle' computer compress the data in hourly snapshots, and store it in a Google Cloud storage (GCS) Nearline bucket.
• B.Push the telemetry data in Real-time to a streaming dataflow job that compresses the data, and store it in Google BigQuery.
• C.Push the telemetry data in real-time to a streaming dataflow job that compresses the data, and store it in Cloud Bigtable.
• D.Have the vehicle's computer compress the data in hourly snapshots, a Store it in a GCS Coldline bucket.

You are building a continuous deployment pipeline for a project stored in a Git source repository and want to ensure that code changes can be verified deploying to production. What should you do?

• A.Use Spinnaker to deploy builds to production using the red/black deployment strategy so that changes can easily be rolled back.
• B.Use Spinnaker to deploy builds to production and run tests on production deployments.
• C.Use Jenkins to build the staging branches and the master branch. Build and deploy changes to production for 10% of users before doing a complete rollout.
• D.Use Jenkins to monitor tags in the repository. Deploy staging tags to a staging environment for testing.
  After testing, tag the repository for production and deploy that to the production environment.
