Which of the following is a disadvantage of the star topology? A. When a port on the central concentrating device fails, the attached end device loses connectivity to the rest of the network. B. When the central concentrating device experiences a complete failure, all attached devices lose connectivity to the rest of the network. C. In a star topology, a more expensive type of host must be used when compared to the host used when implementing a physical bus. D. It is more difficult to add stations and troubleshoot than with other topologies.
