Jena would like to configure her organization’s switches so that they do not allow systems connected to a switch to spoof MAC addresses. Which one of the following features would be helpful in this configuration?
A. Loop protection
B. Port security
C. Flood guard
D. Traffic encryption
Correct Answer: B
Port security restricts the number of unique MAC addresses that may originate from a single switch port. It is commonly used to prevent someone from unplugging an authorized device from the network and connecting an unauthorized device but may also be used to prevent existing devices from spoofing MAC addresses of other devices.
