Layer 2 switching provides which of the following?
1. Hardware-based bridging (ASIC)
2. Wire speed
3. Low latency
4. Low cost
A. 1 and 3
B. 2 and 4
C. 1, 2 and 4
D. All of the above
Answer: Option D
Solution(By Examveda Team)
Switches, unlike bridges, are hardware based. Cisco says its switches are wire speed and provide low latency, and I guess they are low cost compared to their prices in the 1990s.This Question Belongs to Networking >> Spanning Tree Protocol
What is the purpose of Spanning Tree Protocol in a switched LAN?
