Certified Information Systems Security Professional (CISSP) — Question 413

When telephones in a city are connected by a single exchange, the caller can only connect with the switchboard operator. The operator then manually connects the call. This is an example of which type of network topology?

Answer options

• A. Point-to-Point Protocol (PPP)
• B. Bus
• C. Star
• D. Tree

Correct answer: C

Explanation

The correct answer is C, Star, because the switchboard operator acts as a central connection point for all calls, which is characteristic of a star topology. Options A, B, and D do not accurately describe this scenario, as they refer to different network configurations that do not involve a central operator manually connecting calls.
