Answer Description

A Class B network, with a default subnet mask of 255.255.0.0, can support up to 65,534 hosts, which comfortably accommodates the 2,000 devices needed, without the excessive address space that a Class A network would provide. Class A networks support up to approximately 16.7 million hosts, which would be excessive and wasteful for the school's requirements. Conversely, Class C, supporting only up to 254 hosts per network, would not provide sufficient addresses, and using Class D would be inappropriate as it is reserved for multicast.
