Correct B

The best option for reducing the time spent performing manual operations while following Site Reliability Engineering principles would be B. Create a Managed instance Group with a single instance and use health checks to determine the system status. A Managed Instance Group (MIG) is a GCP service that automatically creates, scales, and deletes instances based on the policies that you set. By creating a MIG with a single instance, you can set up health checks to automatically detect when the instance is crashing and replace it with a new instance, without manual intervention. This ensures that the service is always available, and it can reduce the time spent recreating the service and also minimize the risk of human errors.

definitely B

Ans: B Exam passed and taken on 19/12/2022, 50/50 from this dump without buying the full access and looking for 'devops' word here: https://www.examtopics.com/discussions/google/1/

I think that the answer is B, Although SRE principles guide you to find the root cause and post-mortem, the question clearly asks you to: Reduce time spent on manual operations. Therefore the answer is B (Although deep in my heart I would personally combine A and B)

B is correct

Submit B in the exam

B - Managed Instance Group with one Compute Engine instance will take care of this use case.

answer is A. If the root cause of crashing is not found and fixed, the crashing will still happen frequently even if we go MIG. Waste of money and time and does not follows SRE principles

B because it automates toil. I can't think of a better answer.

Answer B, SRE principles says remove the toil where ever possible. MIG will fit here by automating the VM creation.

IMO - SRE practice should be to get the root cause of crashing of VM and fix it. MIG will not help here.
