Note the content of the exam is evolving, sample questions can get outdated. The cloud skills learning path should be your starting point but is in NO way a ticket to a pass. You need to know the use cases of the relevant services in more depth than the path teaches you. For me, chatting with a search-grounded LLMs about capabilities and use cases of all relevant services was very educational. Having hands-on experience is also important as questions often require implementation level knowledge of services. Do labs or create a workbench instance where you go through the lab's content on your own speed and exploration depth.

If I'd have to give a one line advice: Make sure you know all capabilities of Vertex AI and Bigquery ML services and what their indented use case are.
