About this Exam
The AWS Certified Database Specialty (DBS-C01) validates expertise in recommending, designing, and maintaining optimal AWS database solutions. This certification covers the full spectrum of AWS database services including Amazon RDS, Aurora, DynamoDB, Redshift, ElastiCache, Neptune, DocumentDB, Keyspaces, and QLDB. You will be tested on database design principles including normalization, denormalization, partition key design for DynamoDB, and choosing the right database engine for a given workload. The exam covers migration strategies using AWS Database Migration Service (DMS), Schema Conversion Tool (SCT), and the operational aspects of database management including backup, restore, and disaster recovery. Performance optimization is a major theme, testing your knowledge of read replicas, connection pooling, caching strategies with ElastiCache, and query performance tuning. Security topics include encryption at rest and in transit, IAM database authentication, and network isolation. This certification is ideal for database administrators and architects managing complex database environments on AWS.
