The Google Cloud Platform exams do have a lot of comparisons to the AWS exams. Still, in our opinion, for most people, the GCP-PCA Professional Cloud Architect exam will be more complicated than the AWS Certified Solutions Architect Professional exam.
One difference is that Google expects every Solutions Architect to come from a dev background. Now, this might not be an issue for most people, but some would be entirely thrown off by a question asking them to debug some Python code that has nothing to do with GCP.
But this leads to the vital difference: the GCP-PCA certification revolves entirely around professionally performing the Cloud Architect role rather than around the platform itself. There is significant value in this because it can better represent real-world ability. But this can also make it much harder because the scope is almost limitless. Many exam questions have nothing to do with Google.
The Google GCP-PCA exam preparation guide is designed to provide candidates with necessary information about the Professional Cloud Architect exam. It includes exam summary, sample questions, practice test, objectives and ways to interpret the exam objectives to enable candidates to assess the types of questions-answers that may be asked during the Google Cloud Platform - Professional Cloud Architect (GCP-PCA) exam.
