  • Workflows: A service that allows you to orchestrate and automate Google Cloud and HTTP-based API services with serverless workflows. Understand how to design, deploy, and manage workflows to automate complex processes.

Tips for the Exam

  • Understand Use Cases: The exam questions often present use-case scenarios. For example, “Client A has this situation and now they want to achieve this goal. Which service would you recommend?” Be prepared to analyze and respond to such scenarios by understanding the strengths and appropriate applications of each Google Cloud service.
  • Hands-on Practice: Use Google Cloud’s free tier to get hands-on experience with the services. Practical knowledge is crucial.
  • Study the Documentation: Google’s documentation is comprehensive and regularly updated. Make sure to review the latest features and best practices.
  • Take Practice Exams: Practice exams can help you get a feel for the types of questions that will be asked and identify areas where you need further study.
  • Google Cloud Skills Boost: Consider using Google Cloud Skills Boost, a platform offering a variety of courses to help you become more familiar with Google Cloud Platform (GCP) and prepare for the exams. It offers extensive training material and labs that can be very beneficial for your exam preparation. Note that this platform requires a subscription, so there is a cost involved.
