How to Compare AWS, Azure, and Google Cloud Foundation Exams Before Choosing One
Choosing your first cloud certification is a strategic decision. This article breaks down the exam domains, candidate profiles, and study approaches for the three leading entry-level cloud exams, using only official sources. Whether you're aiming for AWS, Azure, or Google Cloud, you'll find clear, actionable insights to decide which path aligns with your career goals.
Overview of Foundational Cloud Certifications
The three major cloud providers offer entry-level certifications designed for individuals new to cloud computing or in non-technical roles who need to demonstrate cloud fluency. The AWS Certified Cloud Practitioner (CLF-C02) validates overall knowledge of the AWS Cloud, independent of a specific job role. The Microsoft Azure Fundamentals (AZ-900) exam targets technology professionals who want to show foundational knowledge of cloud concepts and Azure services. The Google Cloud Digital Leader certification, as indicated by the source, is aimed at accelerating digital transformation and understanding how Google Cloud can solve business challenges. All three exams serve as common starting points for cloud careers.
Exam Structure and Domains
AWS CLF-C02 consists of 50 scored questions and 15 unscored pretest questions. The minimum passing scaled score is 700 out of 1000. Content domains and weights are: Cloud Concepts (24%), Security and Compliance (30%), Technology and Services (34%), and Billing, Pricing, and Support (12%). Azure AZ-900 has a passing score of 700 as well, though the source did not specify question counts. Skills measured include: Describe cloud concepts (25–30%), Describe Azure architecture and services (35–40%), and Describe Azure management and governance (30–35%). The Google Cloud Digital Leader source did not include explicit exam domain percentages, but its thematic focus was on digital transformation, cloud solutions, and business value. Candidates should refer to Google Cloud’s official certification page for the latest domain outline before studying.
Candidate Profile and Prerequisites
The AWS target candidate has up to 6 months of exposure to AWS Cloud design, implementation, or operations. It’s suitable for those in early AWS career stages or working alongside cloud roles. The Azure candidate should have skills and experience in areas like infrastructure management, database management, or software development. The Google Cloud Digital Leader is positioned for business and technical professionals who want to understand how to leverage Google Cloud for digital transformation. None of these exams require deep coding or architecture skills; they test foundational concepts and service knowledge.
Study Strategies and Practice Resources
Avoid the common mistake of underestimating these exams. Use official exam guides as your primary roadmap. For AWS, study the in-scope services and technologies listed in the CLF-C02 guide. For Azure, focus on the Skills Measured document and Microsoft Learn paths. For Google Cloud, the source suggests exploring Google Cloud’s learning resources and its “Accelerate your digital transformation” materials. Complement your reading with hands-on labs: use AWS Free Tier to build simple S3 buckets and EC2 instances, Azure free account to create VMs and storage accounts, and Google Cloud’s Qwiklabs for introductory quests. Schedule a practice test early to identify weak domains — AWS provides official practice exams, and Microsoft offers a free Practice Assessment. The Google Cloud source did not mention practice exams, so check Google Cloud’s website for preparation tools.
Weekly Study Plan Example
Allocate 4–6 weeks part-time. Week 1: Cloud concepts (shared responsibility, benefits, deployment models). Week 2: Core services — for your chosen platform, deep dive into compute, storage, networking, and databases. Week 3: Security, compliance, and governance features. Week 4: Billing, pricing, and support plans. Week 5: Review all domains and take a timed practice exam. Week 6: Target your weakest areas with focused labs and reread official FAQs. Adjust the schedule based on the weightings from the exam guide. Because AWS and Azure provide clear domain weights, you can allocate study time proportionally. For Google Cloud, monitor the official website for the most current breakdown and adapt the plan accordingly.
Common Candidate Mistakes
1. Memorizing service names without understanding use cases. 2. Neglecting security and compliance domains, which are heavily weighted in AWS CLF-C02 (30%) and important in AZ-900. 3. Ignoring unscored questions — in AWS they don’t affect your score, but you won’t know which they are, so treat all questions seriously. 4. Not reading the question’s finite context: many answers are plausible, but only one aligns perfectly with the given scenario. 5. Assuming the exam will be easy because it’s foundational; the pass mark of 700 requires a solid grasp of all weighted areas.
When to Re-check Official Pages
Exam content updates periodically. AWS updates the CLF-C02 guide when services or concepts change; check the certification page before you start studying. Microsoft notes that exams are updated to reflect required skills, and the English version is updated first; localized versions follow approximately eight weeks later. For Google Cloud, always visit the certification website for the latest exam outline, as the provided source may not reflect the most current version. Bookmark the official exam pages and revisit them at least two weeks before your scheduled exam to catch any last-minute changes.

Frequently asked questions
Which foundational cloud exam is the easiest?
Perceptions vary, but no exam is objectively easy. AWS CLF-C02 and Azure AZ-900 both require a 700/1000 passing score and cover broad content. The difficulty depends on your familiarity with the platform. The Google Cloud Digital Leader focuses on digital transformation and may appeal more to business professionals, but without published domain weights in the source, its depth is harder to gauge.
Can I pass without hands-on experience?
Yes, but it’s harder. For AWS and Azure, the candidate descriptions assume up to 6 months of exposure or general IT experience. Hands-on labs reinforce concepts like virtual machines, storage tiers, and billing dashboards, which appear in scenario-based questions.
How long does preparation typically take?
With 5–8 hours of study per week, most candidates prepare in 4–6 weeks. Adjust based on your background; if you already work with a cloud platform, you may need less time.
Are there any prerequisites for these exams?
No formal prerequisites. AWS recommends 6 months of exposure, Microsoft suggests IT experience, and Google Cloud positions the Digital Leader for anyone involved in digital transformation—but you can register for any exam without prior certifications.
