CCNA: Cisco Certified Network Associate — Question 1071

Which switch concept is used to create separate broadcast domains?

Answer options

• A. STP
• B. VTP
• C. VLAN
• D. CSMA/CD

Correct answer: C

Explanation

VLAN (Virtual Local Area Network) is the correct answer because it allows the segmentation of a network into separate broadcast domains, enhancing security and reducing broadcast traffic. STP (Spanning Tree Protocol) is used for loop prevention, VTP (VLAN Trunking Protocol) manages VLAN configurations, and CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is a protocol used in Ethernet networks to manage access to the shared medium.
