Google Cloud

Google Cloud organizes its certifications into three tiers. Foundational now has two credentials, Cloud Digital Leader and the Generative AI Leader cert Google added in 2025, both business-level with no prerequisites and no hands-on requirement. Associate covers day-to-day builders: Associate Cloud Engineer, plus the newer Associate Data Practitioner and Associate Google Workspace Administrator. Professional is the deep end, headlined by Professional Cloud Architect and Professional Data Engineer alongside role certs for security, networking, DevOps, databases, developers, and machine learning, and Google added Professional Security Operations Engineer in September 2025.

Pricing scales with tier: $99 for Foundational exams (the Generative AI Leader runs 90 minutes), $125 for Associate, and $200 for Professional, each a 2-hour exam of 50 to 60 questions. One fact worth planning around: Professional certifications are valid for only 2 years (Foundational and Associate get 3), a shorter cycle than the 3 years AWS and Microsoft role certs give you. Google softens the recert hit with shorter renewal exams at roughly half price ($75 to renew Associate Cloud Engineer, $100 for Professional Cloud Architect) inside a renewal window that opens 60 days before a Professional cert lapses, and select certs can add a year of validity through continuing education instead of retesting.

The typical path is Associate Cloud Engineer first unless you already run production workloads on GCP, then the Professional cert that matches your role. CertCompanion carries 14 Google Cloud practice banks spanning all three tiers, including 1,397 questions for Professional Cloud Architect, 1,063 for Professional Data Engineer, 1,075 for Professional Cloud Security Engineer, 902 for Associate Cloud Engineer, and 811 for Generative AI Leader. Every exam starts with 30 free questions, so you can gauge difficulty before committing.

The 2025-2026 refresh tilted the catalog toward AI and security: Generative AI Leader became the second Foundational cert, Professional Security Operations Engineer arrived for detection-and-response roles, and Associate Data Practitioner filled the gap below Professional Data Engineer. We carry practice banks for all three, so you can prep for the newest exams the same way you would for the established ones.
