Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 50

What are two reasons why broadcast radiation is caused in the virtual machine environment? (Choose two.)

Answer options

• A. vSwitch must interrupt the server CPU to process the broadcast packet.
• B. The Layer 2 domain can be large in virtual machine environments.
• C. Virtual machines communicate primarily through broadcast mode.
• D. Communication between vSwitch and network switch is broadcast based.
• E. Communication between vSwitch and network switch is multicast based.

Correct answer: A, B

Explanation

Option A is correct because the vSwitch requires CPU resources to process broadcast packets, leading to potential performance issues. Option B is also correct as larger Layer 2 domains can increase broadcast traffic. The other options are incorrect because C suggests that broadcast is the primary communication method, while D and E incorrectly characterize the nature of communication between the vSwitch and the network switch.
