Your application is logging to Stackdriver. You want to get the count of all requests on all
/api/alpha/* endpoints.
What should you do?

• A. Add a Stackdriver counter metric for endpoint:/api/alpha/*.
• B. Export the logs to Cloud Pub/Sub and count lines matching /api/alpha.
• C. Add a Stackdriver counter metric for path:/api/alpha/.
• D. Export the logs to Cloud Storage and count lines matching /api/alpha.

You recently deployed an application to GKE where Pods are writing files to a Compute Engine persistent disk. You have created a PersistentVolumeClaim (PVC) and a PersistentVolume (PV) object on Kubernetes for the disk, and you reference the PVC in the deployment manifest file.
You recently expanded the size of the persistent disk because the application has used up almost all of the disk space. You have logged on to one of the Pods, and you notice that the disk expansion is not visible in the container file system. What should you do?

• A. Recreate the application Pods by running the kubectl delete deployment DEPLOYMENT_NAME
  && kubectl apply deployment.yaml command, where the DEPLOYMENT_NAME parameter is the name of your deployment and deployment.yaml is its manifest file.
• B. Set the spec.resources.requests.storage value of the PVC object to match the size of the persistent disk. Apply the updated configuration by using kubectl.
• C. Set the spec.capacity.storage value of the PV object to match the size of the persistent disk.
  Apply the updated configuration by using kubectl.
• D. In the Pod, resize the disk partition to the maximum value by using the fdisk or parted utility.

You are developing a mobile application that allows users to create and manage to-do lists. Your application has the following requirements:
- Store and synchronize data between different mobile devices.
- Support offline access.
- Provide real-time updates on each user's device.
You need to implement a database solution while minimizing operational effort. Which approach should you use?

• A. Use Firestore as the database. Configure Firestore offline persistence to cache a copy of the Firestore data. Listen to document changes to update applications whenever there are document changes.
• B. Create a Bigtable instance. Design a database schema to avoid hotspots when writing data. Use a Bigtable change stream to capture data changes.
• C. Create a Cloud SQL for MySQL instance. Implement a data model to store to-do list information.
  Create indexes for the most heavily and frequently used queries.
• D. Implement a SQLite database on each user's device. Use a scheduled job to synchronize each device database with a copy stored in Cloud Storage.

You are a developer of a new customer-facing help desk chat service that is built on Cloud Run.
Your customers use the chat option on your website to get support. The application saves each transcript as a text file with a unique identifier in a Cloud Storage bucket. After the conversation is done and before the chat window is closed, the customer receives a link to the chat transcript.
You want to provide access to the chat transcript link for 2 hours. You need to configure this access using an approach that prioritizes security and follows Google-recommended practices.
What should you do?

• A. Set the ACL permission on the Cloud Storage bucket. Set the permission of each text file to allUsers with READER access. Delete each text file 2 hours after it is created.
• B. Set the permission on the Cloud Storage bucket with the text files to allUsers. Delete each text file
  2 hours after it is created.
• C. Create a signed URL for each text file that expires after 2 hours.
• D. Create a new Cloud Storage bucket for each user. Grant the user access to the bucket with a conditional IAM role that expires after 2 hours.
