Key domains include Architecture & Data Model, CQL & Storage Engine, Drivers, Performance, Security & DSE and Operations & Repair.
Sample Questions
Try a few questions to see what the full exam is like.
Why does Cassandra recommend FROZEN for nested collection types like list>>?
A client receives ReadTimeoutException with received=2, required=3, dataPresent=true. What does this mean?
Which is the default value of gc_grace_seconds on a new table?
What is the difference between read repair and anti-entropy repair?
When using R=ONE and W=ONE in an RF=3 cluster, what consistency guarantee do you get?
Why This Certification Opens Doors
In production environments, theoretical knowledge of Cassandra is insufficient. The real-world impact of this certification lies in its validation of hands-on skills to build systems that are truly scalable, fault-tolerant, and performant under load. It proves you can translate business requirements into efficient data models, diagnose and resolve performance bottlenecks, and implement robust operational practices-skills that directly affect application reliability, cost efficiency, and development velocity for organizations relying on distributed data.
