Google Cloud Certified - Professional Cloud Database Engineer 認定 Professional-Cloud-Database-Engineer 試験問題 (Q80-Q85):

質問 # 80
You are starting a large CSV import into a Cloud SQL for MySQL instance that has many open connections. You checked memory and CPU usage, and sufficient resources are available. You want to follow Google-recommended practices to ensure that the import will not time out. What should you do?

A. Ensure that the service account has the Storage Admin role.
B. Increase the number of CPUs for the instance to ensure that it can handle the additional import operation.
C. Increase the amount of memory allocated to your instance.
D. Close idle connections or restart the instance before beginning the import operation.

正解：D

解説：
CPU and memory are OK so that elimiates B and D. C is nonsense which leaves A. This is supported by Google's own documention (read recommended practices) which says close unused operations and re-start the instance. This is the best way to ensure maximum resources for the import operation.

質問 # 81
You are working on a new centralized inventory management system to track items available in 200 stores, which each have 500 GB of dat a. You are planning a gradual rollout of the system to a few stores each week. You need to design an SQL database architecture that minimizes costs and user disruption during each regional rollout and can scale up or down on nights and holidays. What should you do?

A. Use Oracle Real Application Cluster (RAC) databases on Bare Metal Solution for Oracle.
B. Use a Biglable cluster with autoscaling.
C. Use sharded Cloud SQL instances with one or more stores per database instance.
D. Use Cloud Spanner with a custom autoscaling solution.

正解：C

質問 # 82
You are the database administrator of a Cloud SQL for PostgreSQL instance that has pgaudit disabled. Users are complaining that their queries are taking longer to execute and performance has degraded over the past few months. You need to collect and analyze query performance data to help identity slow-running queries.
What should you do?

A. White a Logs Explorer query to identify database queries with high execution times.
B. View Cloud SQL operations to view historical query information.
C. Review application logs to identify database calls.
D. Use the Query Insights dashboard to identify high execution times.

正解：D

解説：
A Cloud SQL instance configured for HA is also called a regional instance and has a primary and secondary zone within the configured region. Within a regional instance, the configuration is made up of a primary instance and a standby instance. Through synchronous replication to each zone's persistent disk, all writes made to the primary instance are replicated to disks in both zones before a transaction is reported as committed. In the event of an instance or zone failure, the standby instance becomes the new primary instance. Users are then rerouted to the new primary instance. This process is called a failover.

質問 # 83
Your company's mission-critical, globally available application is supported by a Cloud Spanner database.
Experienced users of the application have read and write access to the database, but new users are assigned read-only access to the database. You need to assign the appropriate Cloud Spanner Identity and Access Management (IAM) role to new users being onboarded soon. What roles should you set up?

A. roles/spanner.databaseReader
B. roles/spanner.viewer
C. roles/spanner.databaseUser
D. roles/spanner.backupWriter

正解：A

解説：

質問 # 84
You are developing a Python application that will connect to AlloyDB for PostgreSQL as the backend datastore. Your organization's security requirements do not allow the use of usernames and passwords for database authentication. How should you develop your application-

A. Use the AlloyDB Python connector. Use automated IAM authentication for connectivity.
B. Use any PostgreSQL-compatible Python client. Use a service account name and credential as the username and password respectively during connection.
C. Use any PostgreSQL-compatible Python client. Connect to the AlloyDB cluster by using Identity- Aware Proxy (IAP).
D. Use the AlloyDB Python connector. Enforce SSL connectivity to AlloyDB by using the gcloud alloydb instance updatecommand with the --ssl-mode=ENCRYPTED_ONLYoption.

正解：A

解説：
The AlloyDB Python connector natively supports IAM-based authentication, letting your application obtain short-lived OAuth tokens instead of using static database passwords. This meets the security requirement and integrates seamlessly with AlloyDB for PostgreSQL without additional credential management.
