What is one disadvantage of a centralized network structure?

In a centralized network structure, all data and services are managed from a single central point, which can create a significant disadvantage in terms of dependency. This higher dependency on a single point of failure indicates that if the central node—whether it be a server or a network device—fails, the entire network can be impacted, leading to outages and loss of access for all users. This situation can bring operations to a halt, making it critical for organizations to implement robust redundancies and backup measures to mitigate this risk.

In contrast, while options highlighting greater control over data management, improved response times, and lower administrative overhead may be advantages associated with a centralized structure, they do not address the critical issue of vulnerability that comes from centralizing all resources in one location. Having a single point of failure requires careful consideration in network design to ensure that resilience is built into the architecture.
