JNCIA-Junos: Juniper Networks Certified Associate – Junos (legacy) — Question 26

What are three characteristics of Layer 2 switches? (Choose three.)

Answer options

• A. Layer 2 switches forward broadcast traffic.
• B. Layer 2 switches forward traffic addresses to hosts that reside on the same collision domain.
• C. Layer 2 switches separate multicast domains.
• D. Layer 2 switches separate collision domains.
• E. Layer 2 switches forward traffic addressed to hosts that reside on a different collision domain.

Correct answer: A, B, D

Explanation

The correct answers A, B, and D highlight the functions of Layer 2 switches in managing broadcast traffic, directing traffic within the same collision domain, and isolating collision domains. Option C is incorrect because Layer 2 switches do not inherently separate multicast domains, and option E is wrong as Layer 2 switches do not forward traffic to different collision domains.
