Google Professional Cloud Developer Exam - Topic 1 Question 67 Discussion

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?
C) Use Cloud Monitoring to monitor the CPU utilization, and reduce Spanner processing units by small increments until you find the minimum capacity required.
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.
D) Use Snapshot Debugger to check for application errors, and reduce Spanner processing units by small increments until you find the minimum capacity required.

Wait, can you really reduce processing units without affecting performance?

I heard Cloud Trace can give better insights on request patterns.

Not sure about that, what if the bottleneck is elsewhere?

I think option C makes the most sense for monitoring CPU usage.

I vaguely recall Snapshot Debugger being more about debugging than monitoring performance, so I’m not convinced that’s the right choice here.

I feel like Cloud Logging could be useful for identifying errors, but I’m not clear on how that ties into reducing processing units effectively.

I think Cloud Trace might help us understand the request load better, but I’m a bit confused about how that translates to cost optimization.

I remember we discussed using Cloud Monitoring for performance metrics, but I'm not sure if CPU utilization is the best indicator for Spanner.

Hmm, I'm a bit confused about the different time frames mentioned. I'll need to re-read the question carefully to make sure I understand the sequence of events.

Hmm, this seems like a question about data classification. I'll need to think carefully about the factors that can affect how data is classified.

Ah, I remember learning about this in the training materials. The service ports should be facing downward to ensure proper installation and functionality. I'm confident I can answer this correctly.

I was leaning towards POS metrics, but now I wonder if that really connects to improving pipeline management like SFA does.
