The business wants to keep costs low. Which web service platform and database should you use for the application?

• A.Cloud Run and BigQuery
• B.Cloud Run and Cloud Bigtable
• C.A Compute Engine autoscaling managed instance group and BigQuery
• D.A Compute Engine autoscaling managed instance group and Cloud Bigtable

You are working at a sports association whose members range in age from 8 to 30. The association collects a large amount of health data, such as sustained injuries. You are storing this data in BigQuery. Current legislation requires you to delete such information upon request of the subject. You want to design a solution that can accommodate such a request. What should you do?

• A.Use a unique identifier for each individual. Upon a deletion request, delete all rows from BigQuery with this identifier.
• B.When ingesting new data in BigQuery, run the data through the Data Loss Prevention (DLP) API to identify any personal information. As part of the DLP scan, save the result to Data Catalog.
  Upon a deletion request, query Data Catalog to find the column with personal information.
• C.Create a BigQuery view over the table that contains all data. Upon a deletion request, exclude the rows that affect the subject's data from this view. Use this view instead of the source table for all analysis tasks.
• D.Use a unique identifier for each individual. Upon a deletion request, overwrite the column with the unique identifier with a salted SHA256 of its value.

Your ecommerce platform uses a regional Cloud SQL for PostgreSQL database to store critical order information. The business requests a recovery time objective (RTO) of less than 10 minutes and a recovery point objective (RPO) of 2 minutes to ensure business continuity in the event of a full regional outage. You need to design a disaster recovery strategy for the Cloud SQL database that meets the business ' s strict RTO and RPO requirements. Your design must avoid operational complexity. What should you do?

• A.Configure the Cloud SQL instance with a cross-region read replica. In a disaster, promote the read replica to a standalone, primary instance.
• B.Use Database Migration Service to continuously replicate the database to another instance in a different region. In a disaster, redirect application traffic to the replica.
• C.Schedule hourly automated backups of the Cloud SQL instance to a multi-regional Cloud Storage bucket. In a disaster, restore the latest backup to a new instance in a different region.
• D.Configure the primary instance for high availability (HA). In the event of a regional outage, trigger a failover to the standby instance.
