COH100 vs COH150: Which Cohesity Certification Is Right for You?

Choosing between the COH100 and COH150 exams can be challenging for candidates pursuing a Cohesity certification. Both belong to Cohesity's Protection Associate certification family, but they focus on different technical skills and career paths. COH100 emphasizes DataProtect fundamentals, backup and recovery operations, protection policies, monitoring, and reporting. COH150 focuses on multicloud protection, cloud archiving and tiering, cloud-native backups, workload migration, and cloud deployment.

Quick answer: Choose COH100 if you want to build or validate your core data protection and recovery skills. Choose COH150 if you want to specialize in multicloud data protection and cloud deployment. Cohesity recommends the DataProtect certification as a foundation for the Multicloud path, but neither exam is a formal prerequisite for the other. Your best starting point depends on your current experience and career goals.

This guide compares the COH100 and COH150 exams, including exam requirements, costs, knowledge domains, career relevance, preparation strategies, and the recommended certification path, to help you make an informed decision.

What Are COH100 and COH150?

Cohesity offers two associate-level Protection Associate specializations: DataProtect and Multicloud. Both assess knowledge of the Cohesity Data Cloud platform and the ability to administer and monitor it, but each emphasizes different data protection capabilities.

COH100: Cohesity Certified Protection Associate – DataProtect

The COH100 exam validates foundational knowledge of Cohesity DataProtect concepts and administration. Its main focus areas include platform fundamentals, backup configuration, protection policies, recovery operations, replication, archival, and monitoring and reporting.

This certification is particularly relevant to backup administrators, data protection operators, system administrators, and technical support professionals responsible for protecting enterprise workloads and maintaining recovery readiness.

COH150: Cohesity Certified Protection Associate – Multicloud

The COH150 exam focuses on using and deploying Cohesity solutions in multicloud environments. Candidates are expected to understand cloud delivery models, cloud-based data protection, archiving, tiering, cloud-native backups, workload migration, and deployment considerations across public and hybrid cloud environments.

It is particularly relevant to cloud administrators, infrastructure engineers, backup specialists, and data protection professionals who work with cloud resources or want to expand their multicloud expertise.

COH100 vs. COH150: Key Differences at a Glance

The following table summarizes the main differences between the two certifications based on Cohesity's published exam information.

Important: Neither exam is a formal prerequisite for the other, so candidates can choose the certification that best matches their experience and career goals. However, Cohesity recommends the DataProtect certification as a foundation for the Multicloud path. Candidates who are new to Cohesity data protection may benefit from starting with COH100, while professionals with relevant cloud experience may prefer to pursue COH150 first.

What Topics Does Each Exam Cover?

Understanding the exam objectives is one of the most effective ways to decide which certification matches your existing knowledge and career plans.

COH100 exam domains: DataProtect

Reviewing the official exam domains is one of the best ways to determine which certification matches your existing knowledge and where to focus your preparation.

The largest individual domain is Recovery Concepts at 21.67%, making recovery workflows an important study priority. Data Protection Fundamentals and Protection Concepts are also substantial areas, so candidates should understand why policies are configured in particular ways rather than merely memorize terminology.

COH150 exam domains: Multicloud

The COH150 exam covers six core knowledge areas. The following table summarizes each domain, its exam weight, and the key topics candidates should study.

The largest exam domain is Deployment Considerations at 25%, making cloud deployment requirements and configuration an important study priority. Cohesity Cloud Concepts (21.67%) and Archiving with Cohesity (20%) are also heavily weighted. Together, these three domains account for 66.67% of the exam, so candidates should prioritize them while ensuring they review all six knowledge areas.

Which Exam Should You Take First?

The best starting point depends on your current technical experience and the responsibilities you want to develop. Although neither exam is a formal prerequisite for the other, Cohesity recommends the DataProtect certification as a foundation for the Multicloud path.

Can You Take Both COH100 and COH150?

Yes. Earning both certifications can help you develop broader knowledge across Cohesity's core data protection and multicloud capabilities.

A practical learning sequence is:

1. Start with COH100 to build a foundation in DataProtect administration, backup policies, recovery, and monitoring.

2. Continue with COH150 to develop knowledge of cloud deployment, archiving, tiering, cloud-native backups, and migration.

3. Apply both sets of skills through hands-on practice with protection workflows and cloud-based use cases.

This sequence is a recommended learning approach, not a mandatory exam requirement.

There is also a broader certification goal to consider. According to Cohesity's published certification FAQ, the Cohesity Protection Professional badge is awarded to candidates who earn all three of the following certifications:

● Cohesity Certified Protection Associate – DataProtect

● Cohesity Certified Protection Associate – Multicloud

● Cohesity Certified Implementation Professional – SmartFiles

Therefore, COH100 and COH150 are two important components of this broader credential pathway, but candidates must also earn the SmartFiles certification to complete it.

How to Prepare for COH100 and COH150

Effective preparation starts with understanding the official exam objectives and focusing on the knowledge areas most relevant to your chosen certification.

Prepare for COH100

Focus on DataProtect fundamentals, protection policies, backup configuration, recovery workflows, and monitoring. Pay particular attention to Recovery Concepts, the exam's largest domain at 21.67%.
