Question at position 12 The failure to implement a strong database administrative function is the most common source of database failures in organizations. TrueFalse

BlackTom AI · Accepted Answer

A robust database administration (DBA) function is responsible for backups/recovery, security and access control, performance tuning, capacity planning, patching, monitoring, and change management — failures in any of these areas directly cause database outages, corruption, or data loss.

1) Relevant knowledge points and concepts
- Backup and recovery: regular, tested backups plus recovery plans prevent data loss.
- Security/patching: DBAs apply patches and configure access to prevent breaches.
- Monitoring/performance: DBAs tune queries, indexes, and resources to avoid outages.
- Change control: formal procedures prevent schema or configuration mistakes.
- Organizational role: DBA function provides policies, training, and accountability.

2) Step-by-step reasoning
- Step 1: Identify common database failure outcomes: data loss, downtime, corruption, unauthorized access, or degraded performance.
- Step 2: Map causes to administrative responsibilities. For example, data loss often results from inadequate backups or untested recovery; downtime often results from misconfiguration, capacity shortfalls, or failed deployments without rollback plans; breaches occur from unpatched systems or weak access controls.
- Step 3: Observe that hardware failures or software bugs also cause problems, but good DBA processes (redundancy, patch management, monitoring, vendor updates) mitigate these causes. Therefore, absent a strong DBA function, many other risk sources are not properly controlled.
- Step 4: Conclude that organizational lack of a strong DBA function is the root and most frequent contributor to database failures.

3) Calculations
- Not applicable; reasoning is conceptual and causal rather than numeric.

4) Why the correct answer is correct
Because DBA responsibilities directly address the majority of failure modes; without strong administration, routine tasks that prevent failures aren’t performed, making failures far more likely.

5) Why the other option is incorrect
Choosing False ignores that many specific failure causes trace back to inadequate administration; while other causes exist, they are less common when strong DBA practices are in place.

6) Conclusion
The correct answer is True, which matches the provided answer.
