Who is responsible for managing and administering databases?

• A. System Administrator
• B. Database Administrator
• C. Security Analyst
• D. Network Engineer

Answer: (B)

Database management focuses on the data store itself—the installation, configuration, design, tuning, backups, restores, security within the database, and ongoing maintenance to ensure data is available and performant. That work is the domain of the Database Administrator. They handle tasks like index tuning, query optimization, backup/restore plans, schema changes, user access within the database, and managing replication or failover.

A System Administrator deals with the operating system and server environment that runs the database—patching, provisioning hardware and storage, and overall system health—rather than the database internals. A Security Analyst focuses on protecting systems and data through monitoring, access controls, and risk management, not routine database administration. A Network Engineer handles connectivity, routing, and network security, which supports but is not the responsibility of database administration.

So, the role that is responsible for managing and administering databases is the Database Administrator.
