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

A. to keep up with growing demand for IP addresses and bandwidth
B. to increase the amount of switches a network can handle
C. to purchase the required amount of network devices
D. to create routing tables for the router

A. to keep up with growing demand for IP addresses and bandwidth

Scalability is important in network design to ensure that the network can handle the increasing demands for IP addresses and bandwidth as the network grows. Without considering scalability, the network may not be able to accommodate future growth and could become slow or unreliable. By designing a scalable network, a network architect can ensure that the network can easily expand and adapt to meet the needs of the organization.
