Who should take the CDL?
CDL is a foundational certification: it tests cloud fluency, not engineering skill. There are no prerequisites, and you don't need to write a line of code to pass it.
You're new to the cloud
A first cloud certification. The lessons here assume nothing — every service and term is explained the first time it appears.
You work alongside cloud teams
Sales, project management, finance, support — CDL proves you can follow a technical conversation about Google Cloud and understand what your engineers are proposing.
You're starting a cloud career
Students and career-changers use CDL as the recognised first line on a cloud CV — and as the on-ramp to the associate-level certifications.
You know it, but not on paper
If you've worked around Google Cloud for a while, CDL turns informal experience into a credential a recruiter can verify in one click.
What’s on the CDL exam
Every lesson, question, and mock is weighted to match these official domains.
Digital Transformation with Google Cloud
Why cloud drives digital transformation and its core concepts: the benefits and drivers of transformation, Google Cloud's differentiators, cloud architectures (private, hybrid, multicloud), networking basics, regions and zones, and the IaaS/PaaS/SaaS trade-offs. Official (approximate) weighting ~18%.
Exploring Data Transformation with Google Cloud
The value of data and how Google Cloud manages it: databases vs warehouses vs lakes, data types and the data supply chain, governance, choosing among Cloud Storage, Spanner, Cloud SQL, AlloyDB, Bigtable, BigQuery and Firestore, storage classes, and analytics with Looker, Pub/Sub, Dataflow and Managed Service for Apache Spark. Official (approximate) weighting ~18%.
Innovating with Google Cloud Artificial Intelligence
AI, ML and agentic AI for business value: core definitions, data quality, responsible and explainable AI, choosing Google Cloud AI solutions, Gemini Enterprise Agent Platform, pre-trained APIs, custom models with Agent Studio and AutoML, AI Hypercomputer and BigQuery ML. Official (approximate) weighting ~18%.
Modernize Infrastructure and Applications with Google Cloud
Moving to the cloud and modernizing: migration terms (rehost, replatform, refactor, reimagine), compute terms, Compute Engine, GKE, Cloud Run, hybrid and multicloud products, and the business value of APIs and Apigee. Official (approximate) weighting ~18%.
Trust and Security with Google Cloud
Cloud security concepts and Google's defense-in-depth approach: threats, the CIA triad, zero trust, encryption states, authentication vs authorization, Google Threat Intelligence, Security Command Center, Google Security Operations, AI security (Model Armor, AI Protection), network and identity controls, and how Google earns trust. Official (approximate) weighting ~18%.
Scaling with Google Cloud Operations
Cost control and modern operations: CapEx to OpEx and TCO, financial governance, the resource hierarchy, quotas, budgets and billing reports, Google Cloud Observability, resilience, the golden signals, and SRE concepts (SLIs, SLOs, SLAs). Official (approximate) weighting ~10%.
