A 30-day plan for the ZDTE exam, built from the blueprint
How to split thirty days across the six exam domains so that study time follows the published weights, with a mock exam at the start, the middle and the end.
The Zscaler Digital Transformation Engineer exam is 60 multiple-choice questions in 90 minutes. Zscaler publishes a blueprint that says how much of the exam each domain makes up. A study plan that ignores those weights usually spends too long on the first topic and runs out of days for the last ones. This post sets out a plan that follows them.
Start with the weights
| Domain | Share of exam | Questions out of 60 | Study days |
|---|---|---|---|
| Architecture and Design | 22% | 13 | 5 |
| Implementation and Deployment | 22% | 13 | 5 |
| Operations and Monitoring | 16% | 10 | 3 |
| Troubleshooting and Support | 15% | 9 | 3 |
| Security and Compliance | 14% | 8 | 3 |
| Automation and Optimization | 11% | 7 | 2 |
That is 21 learning days. The other nine go to a baseline, a catch-up day, a checkpoint, two full mocks, two days on the weakest domains, a light review and the exam itself.
The shape of the month
- Day 1: a short mock, taken cold, and the bookings. Create the Zscaler Cyber Academy account, enrol in the free EDU-202 eLearning, and book the exam slot so the date is fixed.
- Days 2 to 6: Architecture. Identity, forwarding methods, PAC strategy, ZPA design and sizing, ZDX design.
- Day 7: catch up and recall. No new material.
- Days 8 to 12: Implementation. Locations, the ZIA policy engines, DLP, Client Connector, log streaming, ZPA build steps, ZDX probes and alerts.
- Day 13: a second short mock. The first two domains are 44% of the exam, so this is the checkpoint that matters most.
- Days 14 to 24: Operations, Troubleshooting, Security, Automation, each ending in its own quiz.
- Days 25 to 29: full mock, weak domains, Zscaler's own practice exam, second full mock, light review.
- Day 30: the exam.
The same routine every day
About 75 minutes, split four ways: 40 minutes learning, 20 minutes answering questions, 10 minutes of flashcards, and 5 minutes logging what was done. The order matters. Reading feels productive, but answering questions is what shows whether anything stayed.
Three habits worth keeping
- Read the scope before the detail. Many questions are scenarios. "All apps slow at one office" and "one app slow everywhere" have opposite answers.
- Prefer the answer with least privilege and least change. Wrong options often work, but grant too much or use the wrong engine.
- Aim for 70% in every domain, not on average. Zscaler does not publish a pass mark and advises this target for each area.
