What is the main drawback of the Client-Server model?

• A. It is faster than all other models
• B. The server represents a single point of failure
• C. It requires less bandwidth
• D. It is less secure than P2P

Answer: (B)

The main drawback of the Client-Server model is that the server represents a single point of failure. In this architecture, clients rely on a server to process requests and provide services or resources. If the server goes down due to hardware failure, software issues, or network problems, all clients lose access to the resources that the server provides. This can significantly disrupt operations for all connected clients and may lead to downtime for applications critical to business or user activities. This characteristic is a fundamental concern with the Client-Server model, as it emphasizes the need for robust server setups, including redundancy and failover systems, to mitigate potential risks associated with this single point of failure. Other options suggest attributes of performance or security but do not address the inherent vulnerability of server reliance in this model.
