COH500

Designing a Cohesity Data Cloud solution requires matching protection requirements, infrastructure capacity, recovery objectives, and security controls to a customer’s environment. The COH500 exam evaluates these architectural decisions through the Cohesity Certified Architect Expert certification. It targets solution architects, technical consultants, presales engineers, and systems engineers who design data protection and cyber resilience solutions across physical, virtual, and cloud infrastructure.

SpanFS Architecture and Cohesity DataProtect Design

Cohesity architecture begins with understanding the distributed storage platform, including SpanFS, cluster components, networking, and deployment options. Candidates should recognize how these technologies support data protection, scalability, and recovery operations.

DataProtect is central to workload protection design. The examination requires understanding supported workloads, protection policies, recovery workflows, and the relationship between business recovery objectives and technical configuration.

Architects must also distinguish the responsibilities of Cohesity services. SmartFiles supports file and object services, while CloudArchive, CloudTier, and replication address different data management requirements. Selecting the appropriate capability depends on the intended use rather than the similarity of product terminology.

Cluster Sizing and Hybrid Cloud Architecture

Solution discovery and architecture design are particularly important for COH500 preparation. Candidates should understand how workload characteristics, retention requirements, data growth, and recovery expectations influence infrastructure sizing.

The Cohesity Web Sizing Tool supports capacity planning, but effective architecture also requires evaluating performance, network connectivity, hardware options, and deployment constraints.

Important design considerations include:

• Choosing appropriate cluster deployment and expansion options.
• Planning protection across on-premises and cloud environments.
• Distinguishing replication, archival, and cloud tiering requirements.
• Using Helios management capabilities, including self-managed environments.
• Supporting organizational separation through multitenancy.

These decisions must reflect the customer’s operational environment and expected recovery behavior.

FortKnox Cyber Vaulting and Data Security Controls

Cyber resilience introduces requirements beyond routine backup administration. Candidates should understand how Cohesity FortKnox, DataLock, anomaly detection, threat scanning, and data classification contribute to different aspects of data protection.

Security architecture also includes role-based access control, multifactor authentication, single sign-on, and platform hardening. Architects need to distinguish preventive controls from detection and recovery capabilities when designing ransomware recovery strategies.

The examination additionally covers integration with third-party security products and the use of Cohesity APIs for custom automation. These capabilities matter when protection workflows must operate within an existing enterprise security architecture.

Capacity Assessment and Siren Troubleshooting

Architectural responsibility continues after initial deployment. Candidates should understand how cluster capacity, performance measurements, and utilization trends reveal opportunities for expansion or configuration changes.

Cohesity Siren supports diagnostic activities and health checks. Understanding when to use platform monitoring, troubleshooting information, and capacity analysis helps distinguish operational issues from architectural limitations.

For COH500 revision, use a web-based practice test that runs in the browser without installation alongside downloadable PDF questions and answers that can be printed and annotated for offline study. Focus on explaining why a particular Cohesity architecture meets workload, security, and recovery requirements, and where an alternative design would be more appropriate.
