[All Professional Cloud Developer Questions]

You recently joined a new team that has a Cloud Spanner database instance running in production. Your manager has asked you to optimize the Spanner instance to reduce cost while maintaining high reliability and availability of the database. What should you do?

  • A. Use Cloud Logging to check for error logs, and reduce Spanner processing units by small increments until you find the minimum capacity required.
  • B. Use Cloud Trace to monitor the requests per sec of incoming requests to Spanner, and reduce Spanner processing units by small increments until you find the minimum capacity required.
  • C. Use Cloud Monitoring to monitor the CPU utilization, and reduce Spanner processing units by small increments until you find the minimum capacity required.
  • D. Use Snapshot Debugger to check for application errors, and reduce Spanner processing units by small increments until you find the minimum capacity required.

Selected Answer: C
Monitoring allows the behavior and requests per sec to Cloud spanner. By observing these parameter, we can optimize Spanner processing units in small increments until we find the minimum capacity required. After these, we can fine tune Cloud spanner parameter so that costs and resource utilization will be within the limit. The key here is observe and improve.
