Final answer:
Among the given options, the statement that switches provide more security protections than hubs for a company's internal network is correct. Switches are intelligent devices that manage data flow to specific devices, unlike hubs.
Step-by-step explanation:
The correct statement about switches among the given options is: B. Switches provide more security protections than hubs do for a company's internal network. Unlike hubs, which broadcast the same data out of each of its ports and let all devices on a network see all data, switches are smarter as they learn the Media Access Control (MAC) addresses of the devices on the network and send data only to the intended recipient. This function enhances security by limiting the data sent to unintended recipients. It also increases network efficiency by reducing unnecessary data transmission. Additionally, D. A Switch contains multiple ports is also a correct statement as a fundamental feature of a switch is having several ports to connect different devices in a network, allowing for communication between them.
