Google Professional Cloud Architect Exam - Topic 6 Question 20 Discussion

Actual exam question for Google's Professional Cloud Architect exam

Question #: 20
Topic #: 6

[All Professional Cloud Architect Questions]

Your company is running its application workloads on Compute Engine. The applications have been deployed in production, acceptance, and development environments. The production environment is business-critical and is used 24/7, while the acceptance and development environments are only critical during office hours. Your CFO has asked you to optimize these environments to achieve cost savings during idle times. What should you do?

ACreate a shell script that uses the gcloud command to change the machine type of the development and acceptance instances to a smaller machine type outside of office hours. Schedule the shell script on one of the production instances to automate the task.

BUse Cloud Scheduler to trigger a Cloud Function that will stop the development and acceptance environments after office hours and start them just before office hours.

CDeploy the development and acceptance applications on a managed instance group and enable autoscaling.

DUse regular Compute Engine instances for the production environment, and use preemptible VMs for the acceptance and development environments.

Wait, can you really change machine types automatically? That’s cool!

Shell scripts are so old school, why not use Cloud Functions?

Not sure about preemptible VMs for dev, they can be unreliable.

I think option B is the best for cost savings.

Preemptible VMs could save costs, but I wonder if they would be reliable enough for the acceptance environment during critical hours.

I think the managed instance group with autoscaling could be a good approach, but I’m not clear on how it would handle the cost savings during idle times.

I'm not entirely sure about the shell script option. It sounds a bit manual, and I think automation is key here.

I remember we discussed using Cloud Scheduler in class; it seems like a good way to automate stopping and starting the environments.

Hmm, this is a tricky one. I'm not totally sure what "multiple means of engagement" means in this context. Is it about giving students different ways to learn and interact with the content? If so, maybe the crossword puzzle option could work, since that's a different activity compared to just lectures and feedback.

I think Widby's comments on credit risk are spot on. We'll need to be really careful about that as the swap nears maturity. The swaption idea is interesting, but I'm not sure it's the best approach here.

Okay, let me think this through. Cracking, IP address spoofing, and tunneling are all techniques used for hacking or evading detection, not for logging network traffic. I'm confident C - Sniffing is the correct answer.

I studied something about environments, and I feel like we discussed that a ready-made environment isn't a strict requirement for using state management databases. So, option D might be a trick question.
