Certification Overview

What This Certification Validates

The CBSS certification validates your ability to deploy, manage, and support Pure Storage Cloud Block Store (CBS) — the enterprise-grade Purity data services of FlashArray brought natively to public cloud environments including AWS, Microsoft Azure, and Google Cloud Platform.

CBS lets organisations run persistent block storage in the cloud with the same data reduction, snapshots, replication, and cyber-resilience capabilities they rely on in their on-premises FlashArray. The exam tests 5 domains: Cloud Solution, Architecture and Best Practices, Deployment, Management, and Solutions — with 60 scored questions plus 10–15 unscored pilot questions in 120 minutes.

FAQs

Frequently Asked Questions

What is the CBSS — Pure Storage Certified Cloud Block Store Specialist certification?
CBSS is the Pure Storage specialist certification for Cloud Block Store — the solution that brings enterprise Purity data services (data reduction, snapshots, synchronous replication, cyber resiliency) natively to public cloud environments. The exam validates your ability to deploy, manage, and support CBS on AWS, Azure, and GCP across 5 domains in a 120-minute exam.
What are the prerequisites for the CBSS exam?
Pure Storage recommends 12–24 months of hands-on experience with Pure Storage products — ideally FlashArray administration combined with public cloud experience (AWS, Azure, or GCP). There is no formal mandatory prerequisite exam, but familiarity with FlashArray administration and cloud networking fundamentals is strongly advised.
What exam domains does CBSS cover and how are they weighted?
CBSS covers 5 domains: Management (25%) — the highest-weighted domain — followed by Cloud Solution (20%), Architecture and Best Practices (20%), Solutions (20%), and Deployment (15%). The exam has 60 scored questions plus 10–15 unscored pilot questions with a 120-minute time limit.
What is Pure Storage Cloud Block Store and why is it relevant in 2025?
Cloud Block Store is Pure Storage's Purity-as-a-Service offering for public cloud. In 2025, hybrid cloud architectures demand consistent data management across on-premises and cloud — CBS solves this by giving cloud VMs the same enterprise storage capabilities (NVMe-grade performance, SafeMode ransomware protection, ActiveCluster for zero-RPO) that FlashArray delivers on-premises.
What does Zetlan Technologies cover in CBSS training?
Zetlan Technologies covers all 5 CBSS exam domains — Cloud Solution, Architecture and Best Practices, Deployment, Management, and Solutions — with expert-led instruction, cloud lab scenarios, and exam-focused preparation for first-attempt success.
