I kept delaying the CDCP exam because I wasn't sure which areas deserved the most attention. I began with the official EXIN material and spent extra time on Data Centre Infrastructure, Power & Cooling, and Environmental Considerations.

The official content was useful for learning the fundamentals, but I needed more exam-style practice to build confidence. I came across ITExamsTopics and started with the free preview before upgrading. The practice questions helped me recognize the areas I needed to review again.

Power and cooling were probably the topics I practiced the most. Going through similar scenarios repeatedly made it easier to understand the concepts instead of just memorizing them. I reviewed security and operations afterward.

Overall, the preparation felt much more manageable once I combined the official material with practice questions. For CDCP, I'd recommend learning the core concepts first and then using ITExamsTopics to test and strengthen your knowledge.
