QUESTION 23

Which network device can be used to capture network traffic for intrusion detection systems without requiring

additional configuration?

A. Hubs

B. Switches

C. Network taps

D. Router

Answer: A

Explanation: The ability to capture traffic may be inherent to a device technology or may require special

features to provide this capability. For example, network hubs by their nature replicate data to all ports.

Switches, on the other hand, rely on features such as port mirroring to permit the copy of specific traffic top

another port.
