What is the primary role of a system administrator?

The primary role of a system administrator is to manage and maintain an organization’s information systems. This includes a wide range of responsibilities such as ensuring that the systems are running smoothly, monitoring system performance, managing user accounts, applying security measures, and troubleshooting issues when they arise. The system administrator acts as the backbone of the IT infrastructure, ensuring that all hardware and software components work together effectively and that the overall system supports the organization's objectives.

The other options represent important functions within an organization but are not the core responsibilities of a system administrator. Designing new software applications typically falls under the purview of software developers or engineers, who focus on creating and building software solutions. Handling customer complaints regarding software is generally the role of customer support or service teams, who are trained to address user issues and feedback. Conducting training sessions for end-users is often the responsibility of training personnel or instructional designers, who specialize in user education rather than system management. Thus, the responsibilities associated with option B distinctly align with the essential duties of a system administrator.
