Hello, I passed the exam on 2/14/2020. My background is that I have a C.S. Masters Degree and all the AWS Certifications along with 5 years+ of AWS Experience. My prep consisted of the following:
A few months of hands-on work experience with GCP
This course
The linux academy course
Several pluralsight courses.
I took the official practice exam (and got all but one question correct)
I took the acloudguru exam simulator. (This was an excellent simulator imo and among the best prep available).
Know the following:
What gcloud commands make it possible create a project?
Know BigTable external data sources
Read over a lot of the role names and functions, espeically those for iam, compute, project roles, primitive roles
Know when you would use a DaemonSet in k8s (do this when you want the same pod running on every node (including new nodes)
Know when to use google groups (pretty much always)
Know the google cloud storage tier options. Know the minimum number of storage days per tier and how to apply this to a use case.
Know that you can use regional cloud storage buckets for compliance reasons as far as where the data resides
