There is one broadcast domain created when you segment a network with a 12-port switch.
<h3>What is a Broadcast domain?</h3>
A broadcast domain may be defined as a reasoning classification of a computer network that is significantly based on all nodes and can extend to each other by broadcast at the data link layer.
A network with a 12-port switch significantly creates 12 collision domains and 1 broadcast domain. This broadcast domain is large enough to perform specific functions within a network.
Therefore, there is one large broadcast domain created when you segment a network with a 12-port switch.
