  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

Explanation:

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.
