HI All,
I took the Google Cloud Associate Cloud Engineer Exam on August 22, 2020 (passed), and here are a few pointers. I had previously utilized Linux Academy to pass AWS Associate Cloud Arch Exam and found the Google Cloud not as comprehensive but it was still super useful. If you have other cloud experiences such as AWS, it made it easy to translate the knowledge over to G-Cloud. It does however need to be supplemented with experience (lab or real life) and reading. Google's documentation is very well written and super easy to understand/follow.
Google Cloud Certified Associate Cloud Engineer exam is intended for the Google Cloud Engineers who are expertise to deploy applications, monitor operations, and manage enterprise solutions. Associate Cloud Engineers can use Google Cloud Console and the command-line interface to perform various tasks to maintain one or more deployed solutions on the Google Cloud Platform.
The Associate Cloud Engineer exam checks one’s expertise to:
- Set up a cloud solution environment
- Plan and configure a cloud solution
- Deploy and implement a cloud solution
- Ensure the successful operation of a cloud solution
- Configure access and security
Due to COVID-19, I took the exam remotely. It is a good way if you want to do the exam at your home.
The first thing is to go to https://webassessor.com/googlecloud, create an account, and login.
Click on Register for an exam button
So there, you can search for the exam and pay it. Maybe you're thinking: Oh, it is remotely, I have the chance to see my notes and search on google, STOP there, before starting the exam, an agent from Google will contact you through the webassessor page, he/she will ask you some questions, ask you by your Passport, request you to switch on the camera in order to see and check that the place where you're is free of distractions.
Other facts:
- Test duration: 120 Minutes.
- The cost was $125.
- The final result is Pass or Fail. You never see feedback, Google cloud evaluation seems a black box.
- When you made the exam remotely, Google Cloud could take between 7-10 days to confirm your final result. Why? I'm not sure, I suppose that they need yo review the video in order to make sure you don't copy or did something illegal during the exam.
What are the Important Topics for the Google Associate Cloud Engineer Exam Preparation?
No doubt, when we discuss the preparation of an exam, the main thing is what should I study, and what are the important topics. But before sharing the important topics for the preparation of Google Cloud Certified Associate Cloud Engineer exam, I’d like to answer a few questions that may be hovering into your mind.
