JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2024) — Question 45

What are two reasons for configuring more than one VLAN on a switch? (Choose two.)

Answer options

• A. A group of clients requires that security be applied to traffic entering or exiting the group's devices.
• B. A group of devices must forward traffic across a WAN.
• C. A group of devices are connected to the same Layer 3 network.
• D. A group of clients requires that the group's devices receive less broadcast traffic than they are currently receiving.

Correct answer: A, D

Explanation

Option A is correct because VLANs can enhance security by isolating traffic among different groups of devices. Option D is also correct as VLANs help reduce broadcast traffic by segmenting the network, ensuring that only relevant devices receive specific broadcasts. Options B and C are incorrect because they do not specifically relate to the benefits of VLAN configurations regarding security and broadcast management.
