Which statement about network administration is true?

The statement that includes hardware and software maintenance accurately reflects the comprehensive nature of network administration. Network administration involves not only maintaining the physical components of the network, such as servers, routers, and switches, but also managing the software that runs on these devices, including operating systems and various network applications. This dual focus is essential for ensuring that the network functions efficiently and securely.

The role of a network administrator encompasses a broad range of tasks, including configuring and maintaining both the hardware infrastructure and the software systems that support network operations. This holistic approach is crucial for effective network performance, as issues can arise from either hardware malfunctions or software failures.

In contrast, focusing solely on hardware maintenance would neglect the significant role that software plays in network functionality, while excluding security measures would leave the network vulnerable to threats. Additionally, considering user support as unrelated to network administration overlooks the necessity for administrators to assist users in navigating network resources and resolving connectivity issues. This reinforces the importance of having a comprehensive understanding of both hardware and software in the realm of network administration.
