What is a challenge associated with maintaining a wired network?

Maintaining a wired network can indeed be complex and labor-intensive, which is a significant challenge. This complexity arises primarily from the physical infrastructure that wired networks require. For instance, installing cables, switches, routers, and all related hardware necessitates careful planning, organization, and physical labor. Over time, maintaining the network involves troubleshooting physical connections, managing cable management systems, and ensuring that all components are functioning optimally.

Additionally, if there are issues such as breakages or the need to upgrade parts of the network, this can require significant effort to navigate through the existing setup due to the physical layout and connections involved. This maintenance requires a clear understanding of the network topology and may involve a steep learning curve, making it a labor-intensive task compared to other networking solutions.

In contrast, options that suggest low installation costs, mobility, flexibility, or fewer technical skills are incorrect in the context of the challenges faced with wired networks, as these characteristics are not typically associated with such networks.
