How Should I Prepare for Oracle 1Z0-1067-25 Before Booking the Exam?

I am preparing for the Oracle 1Z0-1067-25 exam and I am trying to figure out how to organize my practice before I book the exam. Should I spend more time working through OCI Cloud Operations topics first, or start solving practice questions early to see where I am actually weak?

For anyone who has prepared for the Oracle Cloud Infrastructure 2025 Cloud Ops Professional exam, how did you approach areas such as monitoring and observability, automation, resource management, security, and operational troubleshooting? Did you practice each topic separately before combining them, or did you use mixed questions from the beginning? Oracle describes the certification around managing and operating OCI environments, so I am wondering how much hands-on understanding is needed alongside study material.

I am also looking for useful Oracle 1Z0-1067-25 exam questions to supplement Oracle learning resources. I came across PrepBolt while comparing practice resources, but I am not sure whether using practice questions throughout preparation is more effective than saving them for the final stage. I would especially like to know whether reviewing incorrect answers helped others identify gaps in their OCI Cloud Operations knowledge.

My biggest concern is spending too much time on questions without improving my understanding. If you were preparing for 1Z0-1067-25 again, would you focus first on the individual OCI services, use practice questions to find weak areas, or take mixed practice tests from the start? What approach helped you feel ready before scheduling the actual exam?
