Why must a network architect consider scalability when designing a network?

Network scalability is an important consideration for network architects because it ensures that the network can handle an increase in traffic or user demand without having to be completely redesigned. Scalability also allows for the network to be easily expanded or modified to accommodate new technologies or services. By considering scalability when designing a network, the architect can ensure that the network is able to grow and adapt to changing needs without having to be completely redesigned.
