Google Associate Cloud Engineer Exam - Topic 2 Question 96 Discussion

You need to manage a Cloud Spanner Instance for best query performance. Your instance in production runs in a single Google Cloud region. You need to improve performance in the shortest amount of time. You want to follow Google best practices for service configuration. What should you do?
A) Create an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 45% If you exceed this threshold, add nodes lo your instance.
B) Create an alert in Cloud Monitoring to alert when the percentage to high priority CPU utilization reaches 45% Use database query statistics to identify queries that result in high CPU usage, and then rewrite those queries to optimize their resource usage
C) Create an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 65% If you exceed this threshold, add nodes to your instance
D) Create an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 65%. Use database query statistics to identity queries that result in high CPU usage, and then rewrite those queries to optimize their resource usage.

I vaguely recall that rewriting queries can significantly improve performance, so I’m leaning towards D, but I’m not completely confident about the threshold.

This is a good one. I think the key is to use the monitoring and optimization tools provided by Google, so I'm leaning towards either B or D. The main difference seems to be the CPU threshold, so I'll need to weigh the pros and cons of each.

I'm a little confused by the different CPU thresholds in the options. Is there a meaningful difference between 45% and 65%? I'll need to research that a bit more to make sure I understand the implications before selecting an answer.

Okay, I've got this. The answer is clearly B - create a 45% CPU utilization alert and then optimize the high-CPU queries. That's the most comprehensive approach that aligns with the Google best practices requirement.

D) Create an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 65%. Use database query statistics to identity queries that result in high CPU usage, and then rewrite those queries to optimize their resource usage.

Option D is basically the same as Option B, just with a higher CPU threshold. I'd stick with Option B to be on the safe side and not wait until things get too critical.

Haha, Option C is like throwing money at the problem. 65% CPU utilization is way too high before adding more nodes. I'd rather go with the smart approach of Option B.
