What is a critical factor when managing increased database usage to ensure system performance stability?

• A. Capacity planning
• B. Cost management
• C. Data privacy
• D. Feature expansion

Answer: (A)

Capacity planning is crucial for maintaining system performance stability when managing increased database usage. This involves forecasting future storage needs, processing power, and resource allocation based on expected growth in data traffic and user activity. By anticipating the demands on the database, resources can be provisioned accordingly, ensuring that the system can handle the increased load without degradation of service or performance issues.

Successful capacity planning includes analyzing current usage patterns, understanding the scalability limits of the system, and making informed decisions about infrastructure upgrades or optimizations. This proactive approach can prevent performance bottlenecks that could arise from sudden increases in database usage, thereby safeguarding the overall efficiency and responsiveness of the database environment.

While the other options have their importance in the broader context of database management, they do not focus directly on the technical and operational aspects needed to handle increased usage effectively. Cost management relates more to budget considerations than to operational performance, data privacy focuses on compliance and protection rather than usage scalability, and feature expansion pertains to functionality rather than immediate performance stability under increased load.
