Question at position 37 The role of database administration is typically a more hands-on, physical involvement with the management of databases. TrueFalse

BlackTom AI · Accepted Answer

Database administration centers on installing, configuring, operating, maintaining, and troubleshooting database systems, so the statement that it is a more hands-on, physical involvement with database management is true.

1. Relevant knowledge points and concepts
- Database Administrator (DBA) responsibilities: installing DBMS software, creating and configuring databases, managing storage, applying patches, configuring backups and restores, tuning performance, monitoring system health, and enforcing security. These are operational, technical tasks requiring direct interaction with systems.
- Distinction between strategic and hands-on roles: Architects and data modelers often handle high-level design; DBAs handle day-to-day operational tasks.

2. Step-by-step reasoning
- Step 1: List typical DBA tasks: backups, restores, patching, indexing and query optimization, user account management, capacity planning, replication and high-availability setup.
- Step 2: Evaluate the nature of those tasks: each task requires using tools, running commands, editing configurations, and responding to incidents—concrete, technical activities.
- Step 3: Conclude that because the core responsibilities involve direct system interaction, the role is indeed hands-on.

3. Intermediate steps (for procedural clarity)
- Example: To perform a backup, a DBA executes backup commands, verifies backup files, and tests restore procedures—demonstrating physical interaction with the DBMS and storage.
- Example: To tune a query, a DBA analyzes execution plans and modifies indexes or configuration settings—again hands-on work.

4. Why the correct answer is correct
- The DBA’s primary function is operational management of database systems, which inherently requires hands-on technical tasks rather than purely high-level planning.

5. Why the other option is incorrect
- “False” would imply DBAs are not hands-on; that contradicts the standard industry definition and daily job activities which are technical and operational.

6. Conclusion
- Therefore the correct answer is True, which matches the provided answer.
