To maintain optimal performance while handling increasing workloads, a DBA should focus primarily on what?

• A. Data integrity
• B. Throughput
• C. User access controls
• D. Database backup times

Answer: (B)

Focusing on throughput is essential for a Database Administrator (DBA) when handling increasing workloads because throughput represents the amount of processing that a system can handle within a given time frame. It encompasses the efficiency of the database operations such as read and write transactions, and optimizing throughput ensures that the system can manage more requests and larger volumes of data effectively.

As workloads increase, maintaining high throughput means the database can respond quickly to user requests and process data efficiently, which is crucial for performance management. If throughput is not prioritized, the database could become a bottleneck, leading to slow response times and reduced user satisfaction.

While aspects like data integrity, user access controls, and backup times are important components of database management, they primarily focus on other areas of database administration instead of directly enhancing performance under increasing workloads. Data integrity ensures accurate and reliable data but doesn't inherently boost performance. User access controls safeguard the database but also do not impact throughput directly. Backup times are critical for data recovery strategies but are not a measure of operational efficiency in real-time processing scenarios. Thus, the emphasis on throughput is vital for maintaining optimal performance under increasing loads.
