For this question, refer to the Dress4Win case study. You want to ensure that your on-premises architecture meets business requirements before you migrate your solution.
What change in the on-premises architecture should you make?

• A. Replace RabbitMQ with Google Pub/Sub.
• B. Containerize the micro services and host them in Google Kubernetes Engine.
• C. Downgrade MySQL to v5.7, which is supported by Cloud SQL for MySQL.
• D. Resize compute resources to match predefined Compute Engine machine types.

You have a Python web application with many dependencies that requires 0.1 CPU cores and 128 MB of memory to operate in production. You want to monitor and maximize machine utilization. You also to reliably deploy new versions of the application. Which set of steps should you take?

• A. Perform the following:
  1) Create a managed instance group with n1-standard-1 type machines.
  2) Build a Compute Engine image from the production branch that contains all of the dependencies and automatically starts the Python app.
  3) Rebuild the Compute Engine image, and update the instance template to deploy new production releases.
• B. Perform the following:
  1) Create a Kubernetes Engine cluster with n1-standard-1 type machines.
  2) Build a Docker image from the production branch with all of the dependencies, and tag it with the version number.
  3) Create a Kubernetes Deployment with the imagePullPolicy set to "IfNotPresent" in the staging namespace, and then promote it to the production namespace after testing.
• C. Perform the following:
  1) Create a managed instance group with f1-micro type machines.
  2) Use a startup script to clone the repository, check out the production branch, install the dependencies, and start the Python app.
  3) Restart the instances to automatically deploy new production releases.
• D. Perform the following:
  1) Create a Kubernetes Engine (GKE) cluster with n1-standard-4 type machines.
  2) Build a Docker image from the master branch will all of the dependencies, and tag it with "latest".
  3) Create a Kubernetes Deployment in the default namespace with the imagePullPolicy set to "Always".
  Restart the pods to automatically deploy new production releases.

You are using Cloud SQL as the database backend for a large CRM deployment. You want to scale as usage increases and ensure that you don't run out of storage, maintain 75% CPU usage cores, and keep replication lag below 60 seconds. What are the correct steps to meet your requirements?

• A. 1) Enable automatic storage increase for the instance.
  2) Change the instance type to a 32-core machine type to keep CPU usage below 75%.
  3) Create a Stackdriver alert for replication lag, and shard the database to reduce replication time.
• B. 1) Create a Stackdriver alert when storage exceeds 75%, and increase the available storage on the instance to create more space.
  2) Deploy memcached to reduce CPU load.
  3) Change the instance type to a 32-core machine type to reduce replication lag.
• C. 1) Enable automatic storage increase for the instance.
  2) Create a Stackdriver alert when CPU usage exceeds 75%, and change the instance type to reduce CPU usage.
  3) Create a Stackdriver alert for replication lag, and shard the database to reduce replication time.
• D. 1) Create a Stackdriver alert when storage exceeds 75%, and increase the available storage on the instance to create more space.
  2) Deploy memcached to reduce CPU load.
  3) Create a Stackdriver alert for replication lag, and change the instance type to a 32-core machine type to reduce replication lag.

Your company has just recently activated Cloud Identity to manage users. The Google Cloud Organization has been configured as wed. The security learn needs to secure protects that will be part of the Organization.
They want to prohibit IAM users outside the domain from gaining permissions from now on. What should they do?

• A. Configure Cloud Scheduler o trigger a Cloud Function every hour that removes all users that don ' t belong to the Cloud identity domain from all projects.
• B. Create a technical user (e g . crawler@yourdomain com), and give it the protect owner rote at root organization level Write a bash script that
  * Lists all me IAM rules of all projects within the organization
  * Deletes all users that do not belong to the company domainCreate a Compute Engine instance m a project within the Organization and configure gcloud to be executed with technical user credentials Configure a cron job that executes the bash script every hour.
• C. Configure an organization policy to restrict identities by domain
• D. Configure an organization policy to block creation of service accounts

For this question, refer to the Helicopter Racing League (HRL) case study. HRL is looking for a cost-effective approach for storing their race data such as telemetry. They want to keep all historical records, train models using only the previous season ' s data, and plan for data growth in terms of volume and information collected.
You need to propose a data solution. Considering HRL business requirements and the goals expressed by CEO S. Hawke, what should you do?

• A. Use BigQuery for its scalability and ability to add columns to a schema. Partition race data based on season.
• B. Use Cloud SQL for its ability to automatically manage storage increases and compatibility with MySQL. Use separate database instances for each season.
• C. Use Cloud Spanner for its scalability and ability to version schemas with zero downtime. Split race data using season as a primary key.
• D. Use Firestore for its scalable and flexible document-based database. Use collections to aggregate race data by season and event.
