Which of the following is NOT a function of a data centre?

A data centre primarily serves as a centralized facility that houses computing resources for managing and delivering data. Among its key functions are data storage, network management, and hardware maintenance, each of which plays a fundamental role in ensuring the effective operation of information technology systems.

Data storage is a core function of a data centre, as it serves as the repository for large amounts of data that need to be processed, accessed, and backed up. Network management is also essential, as it involves overseeing the connectivity and data flow between different parts of the system, ensuring efficiency and security in communications and data transfer.

Hardware maintenance is crucial for ensuring that the physical components of data centres—like servers, networking gear, and cooling systems—are functioning optimally, which helps prevent downtime and maintain performance.

On the other hand, software development is typically not a primary function of a data centre. While data centres may host applications and tools supporting development work, the actual process of creating software—designing, coding, testing, and deployment—is generally carried out in separate environments and involves different resources than those primarily found in a data centre. Therefore, identifying software development as the correct answer highlights that it does not align with the main operational roles and functions of data centres.
