Google Professional Cloud Database Engineer Exam - Topic 12 Question 22 Discussion

You recently launched a new product to the US market. You currently have two Bigtable clusters in one US region to serve all the traffic. Your marketing team is planning an immediate expansion to APAC. You need to roll out the regional expansion while implementing high availability according to Google-recommended practices. What should you do?
D) Maintain a target of 35% CPU utilization by locating: cluster-a in zone us-central1-a cluster-b in zone us-central2-a cluster-c in zone asia-northeast1-b cluster-d in zone asia-east1-b
A) Maintain a target of 23% CPU utilization by locating: cluster-a in zone us-central1-a cluster-b in zone europe-west1-d cluster-c in zone asia-east1-b
B) Maintain a target of 23% CPU utilization by locating: cluster-a in zone us-central1-a cluster-b in zone us-central1-b cluster-c in zone us-east1-a
C) Maintain a target of 35% CPU utilization by locating: cluster-a in zone us-central1-a cluster-b in zone australia-southeast1-a cluster-c in zone europe-west1-d cluster-d in zone asia-east1-b

Why are we using Europe zones for APAC expansion?

I recall that maintaining a target CPU utilization is crucial, but I can't remember if 23% is too low. I think we should aim for a balance between performance and cost.

I’m a bit confused about the zones. Shouldn't we prioritize clusters in the same region for lower latency? I’m not sure if spreading them out is the best approach.

I think we practiced a question similar to this where we had to choose clusters in different regions. I feel like option C might be the right choice since it covers more regions.

I remember we discussed the importance of regional distribution for high availability, but I'm not sure if 23% or 35% CPU utilization is better for this scenario.

I feel pretty confident about this one. The Google-recommended practices for high availability suggest using multiple clusters across different zones and regions. Based on the information provided, option D looks like the most comprehensive solution to meet the requirements.

This is a tricky one. I'm not sure if I fully understand the implications of the different CPU utilization targets. I'll need to think through the trade-offs between redundancy, performance, and cost before deciding on the best approach.

Okay, I think I've got this. The key is to distribute the clusters across multiple zones and regions to ensure high availability. Based on the options, B and D seem like the best choices since they cover both the US and APAC regions.

Hmm, I'm a bit confused about the CPU utilization targets. Do we need to strictly maintain 23% or 35% in each cluster, or is that just a general guideline? I'll need to re-read the question carefully to make sure I understand the requirements.

This question seems straightforward - we need to set up a highly available Bigtable solution across multiple regions to support the expansion to APAC. The key is to maintain the target CPU utilization while ensuring redundancy.

Hmm, I'm a bit unsure about this one. I'm not super familiar with OpenTelemetry, so I'm not sure if that's the best option. Maybe I should look into the other choices a bit more before deciding.

Ah, the classic 'high availability' question. Gotta love it. I think option B is the safest bet, but if I'm feeling adventurous, maybe I'll go with C and see what happens.

Wait, we need to maintain a target of 23% CPU utilization? That's a pretty low bar. I'd go with option C and spread the clusters across multiple regions to improve availability.

Hmm, this looks like a tricky one. I'm thinking option B might be the way to go, keeping the clusters in the same US region for now and then adding a third cluster in APAC later.
