Suggested Study Path
- Audit the 12 Factors. Visit
12factor.net. This isn’t just theory; it’s the backbone of the exam. Understand why “Store config in the environment” and “Treat logs as event streams” are non-negotiable. - Master the Data Layer. Focus on
Heroku Connectsynchronization patterns and the difference between aFollowerdatabase and aFork. Know when to reach forRedisvs.Postgres. - Lab the Deployment Flow. Use the
CLIto create aPipeline. Practice promoting a slug from staging to production and understand exactly what happens during theSlugcompilation process. - Deep Dive into Security. Memorize the limitations of
ACM(no wildcards, no IPv6) and when you need to pay for a customSSL Endpointor move to aPrivate Space. - Review the Dev Center. Search for “Heroku Exec”, “Heroku Dynos”, and “Log Drains”. The official documentation is the source of truth for all technical limits.
Watch Out For
- The SSL Nuances: Many candidates trip up on the differences between
ACM,SSL Endpoint, andSni Endpoint. Note which ones support older browsers and which ones are free. - Connect Sync Rules: Understand how
Heroku Connecthandles conflict resolution and which Salesforce APIs it uses under the hood for Bulk vs. Streaming data. - Dyno Sleeping: Be crystal clear on which Dyno tiers sleep after inactivity (Free/Hobby) and which provide dedicated resources.
- The 12 Factors vs. Reality: The exam tests the ideal 12-factor state. If a question asks how to handle local file storage, the 12-factor answer is usually “don’t do it—use an external service.”
