Question 35/70
Your company's user-feedback portal comprises a standard LAMP stack replicated across two zones. It is deployed in the us-central1 region and uses autoscaled managed instance groups on all layers, except the database. Currently, only a small group of select customers have access to the portal. The portal meets a 99.99% availability SLA under these conditions However next quarter, your company will be making the portal available to all users, including unauthenticated users. You need to develop a resiliency testing strategy to ensure the system maintains the SLA once they introduce additional user load. What should you do?

C.
A = I think this is wrong… if you increase the instance group size each day you may never get the autoscale to trigger
B = I think it is better to capture existing users input than make one up. It may be more accurate. Ideally you’d better test autoscale of all layers.
C = My choice. You test using captured users input , test autoscale of all layers and also test what would happen if one zone goes down.
D = I think in those exams it is a good idea to assume any parameters if the question does not mention anything.
My guess is that they deploy in two zones to get failover if one zone goes down.
I would recommend a strategy that acutally tested that, making C the right answer
