CCNA: Cisco Certified Network Associate — Question 271

Which three statements are typical characteristics of VLAN arrangements? (Choose three.)

Answer options

• A. A new switch has no VLANs configured.
• B. Connectivity between VLANs requires a Layer 3 device.
• C. VLANs typically decrease the number of collision domains.
• D. Each VLAN uses a separate address space.
• E. A switch maintains a separate bridging table for each VLAN.
• F. VLANs cannot span multiple switches.

Correct answer: B, D, E

Explanation

Option B is correct because inter-VLAN communication necessitates a Layer 3 device, such as a router. Option D is accurate since each VLAN indeed operates within its own distinct address range. Option E is also correct as switches keep individual bridging tables for each VLAN to manage traffic correctly. Options A, C, and F are incorrect as they do not reflect standard VLAN characteristics.
