# Apache Cassandra Database Administration Assessment

## Description
The Apache Cassandra Database Administration test is designed to evaluate the knowledge and skills of job candidates and employees necessary to support Apache Cassandra database configuration, maintenance, and operations, with a primary focus on practical administration competencies. The test measures skill across six key areas: CQL Syntax and Data Modeling, Replication, Consistency, and Read/Write Behavior, Nodetool and Cluster Operations, Compaction Strategies and SSTable Management, Backup, Restore, and Node Lifecycle Operations, and Cassandra Configuration and Security. It assesses a broad range of topics including data modeling concepts, cassandra.yaml configuration, replication strategies, consistency levels, nodetool commands, snitch configuration, backup and restore procedures, SSTable structure, gossip protocol, system table diagnostics, authentication and authorization, and multi-datacenter deployments. The test uses a variety of question formats including Multiple Choice, Multiple Correct Answer, and Essay Composition questions, with questions drawn from a large pool to help prevent cheating. One or more questions are subject to individual time limits to further deter cheating and enhance the predictive validity of results, and artificial intelligence is utilized in the scoring of one or more questions.
