What technique can the database administrator use to monitor performance and detect potential issues over time?

• A. Baseline configuration/trending
• B. Real-time analysis
• C. Load balancing
• D. User training sessions

Answer: (A)

Baseline configuration and trending is a technique that allows a database administrator to monitor performance metrics over time by establishing a reference point against which future performance can be measured. By creating a baseline, the administrator can identify normal operational behavior, which makes it easier to spot deviations that could indicate potential issues, such as slow performance or increased response times.

This approach facilitates proactive management, as it allows for the identification of trends that may lead to capacity issues or inefficiencies. It also aids in performance tuning, as the administrator can compare current performance against historical data to assess the impact of changes made to the database environment.

In contrast, while real-time analysis can provide immediate insights into performance, it does not help in establishing trends over time. Load balancing is focused on distributing workloads across multiple resources to optimize resource use and performance rather than monitoring long-term performance trends. User training sessions, while critical for efficient database use, do not directly contribute to monitoring or detecting performance issues within the database environment.
