What maintenance process can a database administrator implement to handle increased demand and maintain optimal performance?

• A. Optimizing transaction processing
• B. Data transfer optimization
• C. Backup scheduling
• D. System redundancy

Answer: (A)

Choosing to optimize transaction processing is a critical maintenance process a database administrator can implement to manage increased demand and maintain optimal performance. This practice involves analyzing and refining how database transactions are processed to ensure they execute as efficiently as possible. By optimizing transaction processing, the administrator can reduce wait times for users, minimize resource consumption, and improve the overall throughput of the database.

This approach might include techniques such as indexing, which speeds up data retrieval; normalization, which eliminates redundancy and promotes efficiency in data handling; and implementing proper isolation levels to balance performance with data integrity. Efficient transaction processing ensures that databases can handle high workloads effectively, which is essential in environments with fluctuating user demand.

Other methods listed can also be effective for various aspects but do not specifically target transaction efficiency. For example, data transfer optimization generally focuses on improving the performance of data movements between systems or locations rather than optimizing the transactions occurring within the database itself. Backup scheduling ensures data recovery capabilities but does not directly contribute to handling increased operational demand. Lastly, system redundancy enhances availability and reliability but again does not specifically address the need for better transaction performance. Thus, optimizing transaction processing directly correlates with maintaining optimal performance during times of increased demand.
