I cleared the Salesforce Certified Platform Integration Architect exam last week and wanted to share what my prep looked like for anyone currently grinding through it. This exam is no joke. It goes deep on architectural thinking, not just feature knowledge, so if you are preparing the same way you would for an admin or developer cert, you need to recalibrate.

Where I Focused My Study Time

The exam is built around five major topic areas and each one demands a different kind of thinking.
Topic 1 covers evaluating the current system landscape. You need to be comfortable analyzing existing environments, understanding protocols and standards, spotting constraints, and calling out authentication and authorization requirements before any integration work begins.
Topic 2 is about evaluating business needs. This is where the exam gets into gathering functional and non-functional requirements, classifying data by sensitivity, identifying CRM success factors, and understanding how business growth and regulations drive integration decisions. A lot of candidates underestimate this domain and get burned.
Topic 3 bridges business needs and technical specs. You are expected to know how to document systems and patterns, evaluate constraints, define security requirements, and nail down performance expectations like volumes, response times, and latency.
Topics 4 and 5 build on everything above and test your ability to recommend the right solution in scenario-based questions. Most of the trickier questions I saw were in this territory.
The Integration Pattern Questions Are Everywhere
If there is one thing I would tell every candidate, it is this: know your integration patterns cold. The Fire and Forget vs. Request and Reply distinction tripped up people in my study group more than any other concept. Know when Salesforce is the trigger pushing to an external system versus when the external system is calling in. Platform Events play a huge role in these scenarios.
The OData and Salesforce Connect questions also came up more than I expected. Specifically around Identity Type configuration for securing requests from Salesforce to external data sources. Make sure you understand Named Principal versus Per User and why that distinction matters for security and auditability.

What Helped Most

Working through practice questions was the single most effective thing I did. Not because the questions are identical to what you will see, but because the scenario framing trains you to think like an architect rather than a developer. You start recognizing the pattern behind the question before you finish reading it.
The resource I kept coming back to was the Salesforce Plat-Arch-204 Practice Test on Study4Exam. The question sets are well structured and the explanations helped me understand the reasoning behind correct answers, which is exactly what you need for an architect level exam where the logic matters as much as the answer itself.

Final Thoughts

Give yourself enough time with this one. The breadth of integration architecture concepts is significant and the exam rewards candidates who understand the reasoning behind recommendations rather than those who have memorized a feature list. If you are a Salesforce developer transitioning into an architect role, lean into the business requirements and system landscape topics. Those are the areas where technical backgrounds can create blind spots.
