ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

In a star topology, each workstation is cabled to a central hub or switch. If one drop cable is damaged, only the attached workstation is affected; other links continue to operate, satisfying the requirement to localize failures. Adding or removing a node merely involves connecting or disconnecting a single cable at the hub, so other stations remain online. Because only inexpensive twisted-pair runs are needed and no redundant links are required, implementation costs remain moderate. A ring topology stops passing frames when any single link or node fails unless special fault-tolerant mechanisms are used. A full mesh provides excellent fault tolerance but is far more expensive due to the large number of links. An extended bus retains the same single-segment failure exposure as the company's current design. Therefore, a star topology is the most suitable choice.
