Your company has PostgreSQL databases on-premises and on Amazon Web Services (AWS).
You are planning multiple database migrations to Cloud SQL in an effort to reduce costs and downtime. You want to follow Google-recommended practices and use Google native data migration tools. You also want to closely monitor the migrations as part of the cutover strategy.
What should you do?

• A. Use Database Migration Service for one-time migrations, and use third-party or partner tools for change data capture (CDC) style migrations.
• B. Use Database Migration Service to migrate all databases to Cloud SQL.
• C. Use data replication tools and CDC tools to enable migration.
• D. Use a combination of Database Migration Service and partner tools to support the data migration strategy.

You are evaluating Cloud SQL for PostgreSQL as a possible destination for your on-premises PostgreSQL instances. Geography is becoming increasingly relevant to customer privacy worldwide. Your solution must support data residency requirements and include a strategy to:
configure where data is stored control where the encryption keys are stored govern the access to data What should you do?

• A. Replicate Cloud SQL databases across different zones.
• B. Create a Cloud SQL for PostgreSQL instance on Google Cloud for the data that does not need to adhere to data residency requirements. Keep the data that must adhere to data residency requirements on-premises. Make application changes to support both databases.
• C. Use features like customer-managed encryption keys (CMEK), VPC Service Controls, and Identity and Access Management (IAM) policies.
• D. Allow application access to data only if the users are in the same region as the Google Cloud region for the Cloud SQL for PostgreSQL database.

You are using Memorystore for Redis to cache frequently accessed data and improve your application's performance. Recently, your application is experiencing sudden spikes in latency when interacting with the Memorystore for Redis instance. Upon checking the logs, you discover a high number of "evicted keys" messages. You want to reduce the occurrences of latency spikes and their impact on the application. What should you do-

• A. Scale the Memorystore instance to a larger memory size.
• B. Increase the time to live (TTL) value of all the keys within the cache.
• C. Enable read replicas. Deploy additional read replica instances to distribute read workloads.
• D. Redeploy your application to the same zone as the Memorystore instance.

HelioBank is deploying Cloud SQL for MySQL in europe-west1 to support payment processing for example.com. The compliance team requires that data at rest be encrypted with a key that they own and manage in a specific European location, and they must control the key lifecycle including rotation and disablement. They also need all client connections to be encrypted from end to end.
What should they configure?

• A. Create the Cloud SQL for MySQL instance using customer managed encryption keys from Cloud KMS in the required region and require SSL or TLS for client connections
• B. Create the Cloud SQL for MySQL instance with Google managed encryption keys and secure access using VPC Service Controls
• C. Create the Cloud SQL for MySQL instance with Google managed encryption keys and require SSL or TLS
• D. Create the Cloud SQL for MySQL instance using customer managed encryption keys and place it behind Cloud VPN for all client connectivity
