NEW QUESTION # 58
You released a popular mobile game and are using a 50 TB Cloud Spanner instance to store game data in a PITR-enabled production environment. When you analyzed the game statistics, you realized that some players are exploiting a loophole to gather more points to get on the leaderboard. Another DBA accidentally ran an emergency bugfix script that corrupted some of the data in the production environment. You need to determine the extent of the data corruption and restore the production environment. What should you do? (Choose two.)

A. If the corruption is insignificant, perform a stale read and specify a recovery timestamp. Write the results back.
B. If the corruption is insignificant, use backup and restore, and specify a recovery timestamp.
C. If the corruption is significant, use backup and restore, and specify a recovery timestamp.
D. If the corruption is significant, perform a stale read and specify a recovery timestamp. Write the results back.

NEW QUESTION # 59
Your organization is migrating 50 TB Oracle databases to Bare Metal Solution for Oracle. Database backups must be available for quick restore. You also need to have backups available for 5 years. You need to design a cost-effective architecture that meets a recovery time objective (RTO) of 2 hours and recovery point objective (RPO) of 15 minutes. What should you do?

A. Create the database on a Bare Metal Solution server with the database running on flash storage.
Keep a local backup copy on all flash storage.
Keep backups older than one day stored in Actifio OnVault storage.
B. Create the database on a Bare Metal Solution server with the database running on flash storage.
Keep a local backup copy on standard storage.
Use the Oracle Recovery Manager (RMAN) backup utility to move backups older than one day to a Coldline Storage bucket.
C. Create the database on a Bare Metal Solution server with the database running on flash storage.
Keep a local backup copy on all flash storage.
Use the Oracle Recovery Manager (RMAN) backup utility to move backups older than one day to an Archive Storage bucket.
D. Create the database on a Bare Metal Solution server with the database running on flash storage.
Keep a local backup copy on standard storage.
Keep backups older than one day stored in Actifio OnVault storage.

Answer: D

Explanation:
This answer meets the RTO and RPO requirements by using flash storage for the database and standard storage for the local backup copy. It also meets the cost-effectiveness requirement by using Actifio OnVault storage, which is a low-cost, high-performance, and scalable storage solution that integrates with Google Cloud Backup and DR Service1.

NEW QUESTION # 60
An analytics team needs to read data out of Cloud SQL for SQL Server and update a table in Cloud Spanner.
You need to create a service account and grant least privilege access using predefined roles. What roles should you assign to the service account?

A. roles/cloudsql.viewer and roles/spanner.databaseUser
B. roles/cloudsql.editor and roles/spanner.admin
C. roles/cloudsql.client and roles/spanner.databaseReader
D. roles/cloudsql.instanceUser and roles/spanner.databaseUser

Answer: A

Explanation:
To read data out of Cloud SQL for SQL Server, you need to use a service account with the roles/cloudsql.
viewer role on the Cloud SQL instance. This role grants the service account permission to read data from the instance. Whereas roles/cloudsql.instanceUser will only allow to login to cloud SQL instance. No resource will be allowed to view.

NEW QUESTION # 62
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. Use the Query Insights dashboard to identify high execution times.
B. White a Logs Explorer query to identify database queries with high execution times.
C. View Cloud SQL operations to view historical query information.
D. Review application logs to identify database calls.

Answer: A

Explanation:
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.
