NEW QUESTION # 46
Your organization is currently updating an existing corporate application that is running in another public cloud to access managed database services in Google Cloud. The application will remain in the other public cloud while the database is migrated to Google Cloud. You want to follow Google-recommended practices for authentication. You need to minimize user disruption during the migration. What should you do?
- A. Use workload identity federation to impersonate a service account.
- B. Use Google Workspace Password Sync to replicate passwords into Google Cloud.
- C. Migrate the application to Google Cloud, and use Identity and Access Management (IAM).
- D. Ask existing users to set their Google password to match their corporate password.
Answer: A
Explanation:
Updating passwords represents user disruption. Eliminate B. Eliminate C for the same reason. D doesn't make sense, leaves A. From Google's documentation, "Traditionally, applications running outside Google Cloud can use service account keys to access Google Cloud resources. However, service account keys are powerful credentials, and can present a security risk if they are not managed correctly. With identity federation, you can use Identity and Access Management (IAM) to grant external identities IAM roles, including the ability to impersonate service accounts. This approach eliminates the maintenance and security burden associated with service account keys." https://cloud.google.com/iam/docs/workload-identity-federation
NEW QUESTION # 47

Answer: C
NEW QUESTION # 48
Your customer has a global chat application that uses a multi-regional Cloud Spanner instance. The application has recently experienced degraded performance after a new version of the application was launched. Your customer asked you for assistance. During initial troubleshooting, you observed high read latency. What should you do?
- A. Use query parameters to speed up frequently executed queries.
- B. Use SQL statements to analyze SPANNER_SYS.QUERY_STATS* tables.
- C. Change the Cloud Spanner configuration from multi-region to single region.
- D. Use SQL statements to analyze SPANNER_SYS.READ_STATS* tables.
Answer: D
Explanation:
To troubleshoot high read latency, you can use SQL statements to analyze the SPANNER_SYS.READ_STATS* tables. These tables contain statistics about read operations in Cloud Spanner, including the number of reads, read latency, and the number of read errors. By analyzing these tables, you can identify the cause of the high read latency and take appropriate action to resolve the issue. Other options, such as using query parameters to speed up frequently executed queries or changing the Cloud Spanner configuration from multi-region to single region, may not be directly related to the issue of high read latency. Similarly, analyzing the SPANNER_SYS.QUERY_STATS* tables, which contain statistics about query operations, may not be relevant to the issue of high read latency.
NEW QUESTION # 49
Your company is using Cloud SQL for MySQL with an internal (private) IP address and wants to replicate some tables into BigQuery in near-real time for analytics and machine learning. You need to ensure that replication is fast and reliable and uses Google-managed services. What should you do?
- A. Develop a custom data replication service to send data into BigQuery.
- B. Use Cloud SQL federated queries.
- C. Use Datastream to capture changes, and use Dataflow to write those changes to BigQuery.
- D. Use Database Migration Service to replicate tables into BigQuery.
Answer: C
Explanation:
"Datastream is a serverless and easy-to-use Change Data Capture (CDC) and replication service that allows you to synchronize data across heterogeneous databases, storage systems, and applications reliably and with minimal latency. Datastream supports change data streaming from Oracle and MySQL databases to Google Cloud Storage (GCS). The service offers streamlined integration with Dataflow templates to power up to date materialized views in BigQuery for analytics, replicate their databases into Cloud SQL or Cloud Spanner for database synchronization, or leverage the event stream directly from GCS to realize event-driven architectures."
NEW QUESTION # 50
