200-301 Question #812: Real Exam Question with Answer & Explanation

Question

Which two options will help to solve the problem of a network that is suffering a broadcast storm? (Choose two.)

Options

• Aa Layer 3 switch
• Ba hub
• Ca bridge
• Dan access point
• Ea router

Explanation

To resolve a broadcast storm, devices that can segment broadcast domains are required, such as routers and Layer 3 switches.

Common mistakes.

• B. A hub is a Layer 1 device that simply regenerates and retransmits all incoming signals to all other ports, thus propagating broadcast traffic and worsening a broadcast storm.
• C. A bridge operates at Layer 2 and forwards broadcast frames. While it breaks up collision domains, it does not segment broadcast domains, allowing broadcast storms to propagate across connected segments.
• D. An access point is a Layer 2 device that extends a wireless LAN. It forwards broadcast frames within the same broadcast domain and does not act as a broadcast boundary.
