You are planning to migrate a MySQL database to the managed Cloud SQL database for Google Cloud. You have Compute Engine virtual machine instances that will connect with this Cloud SQL instance. You do not want to whitelist IPs for the Compute Engine instances to be able to access Cloud SQL.
What should you do?

（A）Enable private IP for the Cloud SQL instance.

（B）Whitelist a project to access Cloud SQL, and add Compute Engine instances in the whitelisted project.

（C）Create a role in Cloud SQL that allows access to the database from external instances, and assign the Compute Engine instances to that role.

（D）Create a CloudSQL instance on one project. Create Compute engine instances in a different project.Create a VPN between these two projects to allow internal access to CloudSQL.

質問 4

You recently joined a new team that has a Cloud Spanner database instance running in production. Your manager has asked you to optimize the Spanner instance to reduce cost while maintaining high reliability and availability of the database. What should you do?

（A）Use Cloud Trace to monitor the requests per sec of incoming requests to Spanner, and reduce Spanner processing units by small increments until you find the minimum capacity required.

（B）Use Snapshot Debugger to check for application errors, and reduce Spanner processing units by small increments until you find the minimum capacity required.

（C）Use Cloud Logging to check for error logs, and reduce Spanner processing units by small increments until you find the minimum capacity required.

（D）Use Cloud Monitoring to monitor the CPU utilization, and reduce Spanner processing units by small increments until you find the minimum capacity required.

質問 6

You configured your Compute Engine instance group to scale automatically according to overall CPU usage. However, your application's response latency increases sharply before the cluster has finished adding up instances. You want to provide a more consistent latency experience for your end users by changing the configuration of the instance group autoscaler.
Which two configuration changes should you make? (Choose two.)

（A）Remove the health-check for individual VMs in the instance group.

（B）Add the label "AUTOSCALE" to the instance group template.

（C）Increase the target CPU usage for the instance group autoscaler.

（D）Decrease the target CPU usage for the instance group autoscaler.

（E）Decrease the cool-down period for instances added to the group.

質問 7

You are a lead developer working on a new retail system that runs on Cloud Run and Firestore in Datastore mode. A web UI requirement is for the system to display a list of available products when users access the system and for the user to be able to browse through all products. You have implemented this requirement in the minimum viable product (MVP) phase by returning a list of all available products stored in Firestore.
A few months after go-live, you notice that Cloud Run instances are terminated with HTTP 500:
Container instances are exceeding memory limits errors during busy times. This error coincides with spikes in the number of Datastore entity reads. You need to prevent Cloud Run from crashing and decrease the number of Datastore entity reads. You want to use a solution that optimizes system performance. What should you do?

（A）Modify the Cloud Run configuration to increase the memory limits.

（B）Modify the query that returns the product list using integer offsets.

（C）Modify the query that returns the product list using cursors.

（D）Modify the query that returns the product list using limits.

質問 8

Your application stores customers' content in a Cloud Storage bucket, with each object being encrypted with the customer's encryption key. The key for each object in Cloud Storage is entered into your application by the customer. You discover that your application is receiving an HTTP 4xx error when reading the object from Cloud Storage. What is a possible cause of this error?

（A）You attempted the read operation on the object with the base64-encoded SHA256 hash of the customer's key.

（B）You attempted the read operation without the base64-encoded SHA256 hash of the encryption key.

（C）You entered the same encryption algorithm specified by the customer when attempting the read operation.

（D）You attempted the read operation on the object with the customer's base64-encoded key.
