You are building a mobile application that will store hierarchical data structures in a database.
The application will enable users working offline to sync changes when they are back online. A backend service will enrich the data in the database using a service account. The application is expected to be very popular and needs to scale seamlessly and securely. Which database and IAM role should you use?

• A.Use Bigtable, and assign the roles/bigtable.viewer role to the service account.
• B.Use Firestore in Datastore mode and assign the roles/datastore.viewer role to the service account.
• C.Use Firestore in Native mode and assign the roles/datastore.user role to the service account.
• D.Use Cloud SQL, and assign the roles/cloudsql.editor role to the service account.

Your team currently uses Bigtable as their database backend. In your application's app profile, you notice that the connection to the Bigtable cluster is specified as single-cluster routing, and the cluster's connection logic is configured to conduct manual failover when the cluster is unavailable.
You want to optimize the application code to have more efficient and highly available Bigtable connectivity. What should you do?

• A.Configure the app profile to use multi-cluster routing.
• B.Set up Memcached so that queries hit the cache layer first and automatically get data from Bigtable in the event of a cache miss.
• C.Configure a Dataflow template, and use a Beam connector to stream data changes.
• D.Increase the Bigtable client's connection pool size.

You are developing an HTTP API hosted on a Compute Engine virtual machine instance that needs to be invoked by multiple clients within the same Virtual Private Cloud (VPC). You want clients to be able to get the IP address of the service.
What should you do?

• A.Ensure that clients use Compute Engine internal DNS by connecting to the instance name with the url https://[API_NAME]/[API_VERSION]/.
• B.Ensure that clients use Compute Engine internal DNS by connecting to the instance name with the url https://[INSTANCE_NAME].[ZONE].c.[PROJECT_ID].internal/.
• C.Reserve a static external IP address and assign it to an HTTP(S) load balancing service's forwarding rule.
  Clients should use this IP address to connect to the service.
• D.Reserve a static external IP address and assign it to an HTTP(S) load balancing service's forwarding rule.
  Then, define an A record in Cloud DNS. Clients should use the name of the A record to connect to the service.

Your team is trying to reduce their cloud spend, and you want to evaluate your GKE Autopilot cluster costs. When reviewing the manifests, you see that resource requests are currently not specified. Your application is stateless and fault-tolerant, and there are no specific hardware or memory requirements on nodes. You want to modify the cluster to be scalable and cost-effective as quickly as possible while maintaining a cluster with sufficient computing resources. What should you do?

• A.Request that your Pods run as Spot Pods, and use the cloud.google.com/gke-spot=true label in your YAML manifest.
• B.Set up Cloud Trace and Cloud Monitoring, identify the maximum memory used in the past
  30 days, and set the YAML manifest to request that amount of memory.
• C.Request the Balanced compute class in your YAML manifest.
• D.In the YAML deployment configuration manifest, request and set the maximum CPU to 5 vCPU.

You need to migrate an internal file upload API with an enforced 500-MB file size limit to App Engine.
What should you do?

• A.Use CPanel to upload files.
• B.Use signed URLs to upload files.
• C.Use FTP to upload files.
• D.Change the API to be a multipart file upload API.
