CISSP – Information Systems Security Architecture Professional (ISSAP) — Question 7
A network is configured on a Bus topology. Which of the following conditions could cause a network failure? Each correct answer represents a complete solution.
Choose all that apply.
Answer options
- A. A break in a network cable
- B. 75 ohm terminators at open ends
- C. A powered off workstation
- D. An open-ended cable without terminators
Correct answer: D, B, A
Explanation
Answer D is correct because an open-ended cable without terminators can cause signal reflection and network failure. Answer B is also correct, as using 75 ohm terminators at open ends can lead to improper termination, causing issues. Answer A is correct because a break in a network cable can disrupt the connection and lead to failure. However, answer C is incorrect since a powered off workstation does not affect the overall network operation in a Bus topology.
