Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 155

Which of the following statements about collision domains and broadcast domains are correct? (Choose all that apply.)

Answer options

• A. Devices connected to the same bridge form a collision domain.
• B. Devices connected to the same Hub form a collision domain.
• C. Devices connected to the same router form a broadcast domain.
• D. Devices connected to the same hub form a broadcast domain.
• E. Devices connected to the same bridge form a broadcast domain.

Correct answer: B, C, E

Explanation

Option B is correct because devices connected to a Hub share the same collision domain due to the nature of how Hubs operate. Option C is correct as routers separate broadcast domains, meaning devices connected to the same router belong to the same broadcast domain. Option E is also correct as devices connected to the same bridge are in the same broadcast domain. Options A and D are incorrect; a bridge does not create a collision domain and Hubs do not create separate broadcast domains.
