Free Cloud Digital Leader practice exam: Google Cloud CDL exam guide
Domains, format, and cost of the Google Cloud Digital Leader. How to practice with the Brains4Cloud guide, deep dive, labs, and practice exam.
The Cloud Digital Leader (CDL) is Google Cloud's fundamentals certification, designed for both technical and business profiles. It requires no prior experience with the platform and certifies that you understand, at a conceptual level, how Google Cloud can solve problems in digital transformation, data, AI, infrastructure, and security.
What you need to know about the exam
| Questions | ~50-60 (multiple choice and multiple response) |
| Duration | 90 minutes |
| Reference cost | USD 99 |
| Passing score | Pass/fail (Google doesn't publish a scaled score) |
| Validity | 3 years |
| Prerequisites | None |
Official domains
| Domain | Main content |
|---|---|
| Digital transformation with Google Cloud | Cloud models, business cases |
| Data transformation with Google Cloud | BigQuery, data analytics, data architectures |
| Innovating with Google Cloud AI | Agent Platform (formerly Vertex AI), Gemini, AI/ML use cases |
| Infrastructure and application modernization | Compute, containers, migration |
| Trust and security with Google Cloud | Identity, compliance, governance |
| Scaling with Google Cloud operations | Reliability, monitoring, costs |
The data and AI block is one of the heaviest in practice — Google strongly positions BigQuery and its AI/ML tools as differentiators against other clouds, and the exam reflects that.
Common mistakes that make people fail
- ▸Treating it as an in-depth technical exam. The CDL is conceptual and business-oriented — memorizing commands or specific configurations isn't what's assessed.
- ▸Treating data and AI as a single topic. They're two separate domains on the exam — data transformation (BigQuery, architectures) on one side, AI innovation (Agent Platform, Gemini) on the other, with different evaluation logic.
- ▸Not knowing Google Cloud's differentiating use cases. The exam expects you to know when Google Cloud is the best option compared with alternatives, especially in data and AI.

Frequently asked questions
Is it easier than the AZ-900 or the CLF-C02? It's at a similar level of difficulty, though with more emphasis on business and less on the technical details of individual services.
Is it useful for non-technical roles? Yes, it's one of the few cloud certifications explicitly designed for management, sales, or product profiles who need to speak confidently about Google Cloud.
What comes after the CDL? If your interest is technical, the next step is usually an associate-level certification like Associate Cloud Engineer; if your interest is generative AI, check out our Gen AI Leader guide.
