Your organization stores marketing data such as customer preferences and purchase history on Bigtable. The consumers of this database are predominantly data analysts and operations users. You receive a service ticket from the database operations department citing poor database performance between 9 AM-10 AM every day. The application team has confirmed no latency from their logs. A new cohort of pilot users that is testing a dataset loaded from a third-party data provider is experiencing poor database performance. Other users are not affected. You need to troubleshoot the issue. What should you do?
A. Isolate the data analysts and operations user groups to use different Bigtable instances.
B. Check the Cloud Monitoring table/bytes_used metric from Bigtable.
C. Use Key Visualizer for Bigtable.
D. Add more nodes to the Bigtable cluster.
You are building a data warehouse on BigQuery. Sources of data include several MySQL databases located on-premises.
You need to transfer data from these databases into BigQuery for analytics. You want to use a managed solution that has low latency and is easy to set up. What should you do?
A. Create extracts from your on-premises databases periodically, and push these extracts to Cloud Storage. Upload the changes into BigQuery, and merge them with existing tables.
B. Use Cloud Data Fusion and scheduled workflows to extract data from MySQL. Transform this data into the appropriate schema, and load this data into your BigQuery database.
C. Use Datastream to connect to your on-premises database and create a stream. Have Datastream write to Cloud Storage. Then use Dataflow to process the data into BigQuery.
D. Use Database Migration Service to replicate data to a Cloud SQL for MySQL instance. Create federated tables in BigQuery on top of the replicated instances to transform and load the data into your BigQuery database.
Your organization has a security policy to ensure that all Cloud SQL for PostgreSQL databases are secure. You want to protect sensitive data by using a key that meets specific locality or residency requirements. Your organization needs to control the key's lifecycle activities. You need to ensure that data is encrypted at rest and in transit. What should you do?
A. Create the database with Google-managed encryption keys.
B. Create the database with customer-managed encryption keys.
C. Create the database persistent disk with Google-managed encryption keys.
D. Create the database persistent disk with customer-managed encryption keys.
You finished migrating an on-premises MySQL database to Cloud SQL. You want to ensure that the daily export of a table, which was previously a cron job running on the database server, continues. You want the solution to minimize cost and operations overhead. What should you do?
A. Use Cloud Scheduler and Cloud Functions to run the daily export.
B. Create a streaming Datatlow job to export the table.
C. Set up Cloud Composer, and create a task to export the table daily.
D. Run the cron job on a Compute Engine instance to continue the export.
Your company is developing a global ecommerce website on Google Cloud. Your development team is working on a shopping cart service that is durable and elastically scalable with live traffic. Business disruptions from unplanned downtime are expected to be less than 5 minutes per month. In addition, the application needs to have very low latency writes. You need a data storage solution that has high write throughput and provides 99.99% uptime. What should you do?
A. Use Cloud SQL for data storage.
B. Use Cloud Spanner for data storage.
C. Use Memorystore for data storage.
D. Use Bigtable for data storage.
You are running a transactional application on Cloud SQL for PostgreSQL in Google Cloud. The database is running in a high availability configuration within one region. You have encountered issues with data and want to restore to the last known pristine version of the database. What should you do?
A. Create a clone database from a read replica database, and restore the clone in the same region.
B. Create a clone database from a read replica database, and restore the clone into a different zone.
C. Use the Cloud SQL point-in-time recovery (PITR) feature. Restore the copy from two hours ago to a new database instance.
D. Use the Cloud SQL database import feature. Import last week's dump file from Cloud Storage.
Your digital-native business runs its database workloads on Cloud SQL. Your website must be globally accessible 24/7. You need to prepare your Cloud SQL instance for high availability (HA). You want to follow Google-recommended practices. What should you do? (Choose two.)
A. Set up manual backups.
B. Create a PostgreSQL database on-premises as the HA option.
C. Configure single zone availability for automated backups.
D. Enable point-in-time recovery.
E. Schedule automated backups.
You are configuring a new application that has access to an existing Cloud Spanner database. The new application reads from this database to gather statistics for a dashboard. You want to follow Google-recommended practices when granting Identity and Access Management (IAM) permissions. What should you do?
A. Reuse the existing service account that populates this database.
B. Create a new service account, and grant it the Cloud Spanner Database Admin role.
C. Create a new service account, and grant it the Cloud Spanner Database Reader role.
D. Create a new service account, and grant it the spanner.databases.select permission.
You are writing an application that will run on Cloud Run and require a database running in the Cloud SQL managed service. You want to secure this instance so that it only receives connections from applications running in your VPC environment in Google Cloud. What should you do?
A. 1. Create your instance with a specified external (public) IP address.
2.
Choose the VPC and create firewall rules to allow only connections from Cloud Run into your instance.
3.
Use Cloud SQL Auth proxy to connect to the instance.
B. 1. Create your instance with a specified external (public) IP address.
2.
Choose the VPC and create firewall rules to allow only connections from Cloud Run into your instance.
3.
Connect to the instance using a connection pool to best manage connections to the instance.
C. 1. Create your instance with a specified internal (private) IP address.
2.
Choose the VPC with private service connection configured.
3.
Configure the Serverless VPC Access connector in the same VPC network as your Cloud SQL instance.
4.
Use Cloud SQL Auth proxy to connect to the instance.
D. 1. Create your instance with a specified internal (private) IP address.
2.
Choose the VPC with private service connection configured.
3.
Configure the Serverless VPC Access connector in the same VPC network as your Cloud SQL instance.
4.
Connect to the instance using a connection pool to best manage connections to the instance.
You are managing a small Cloud SQL instance for developers to do testing. The instance is not critical and has a recovery point objective (RPO) of several days. You want to minimize ongoing costs for this instance. What should you do?
