A. True
B. False

Answer 3

A. True

Explanation: A Rogue access point is really any access point on a network that has been connected without approval. Rogue access points and home routers connected to a corporate network can at time remain unnoticed, cause security breaches and interfere with existing wireless channels. Rogue APs should always be identified and taken down as fast as possible. An Evil Twin is the worst case scenario with Rogue APs as Evil Twins are set up specifically for the purpose of mimicking a real production network and duping users into connecting to it for the purpose of intercepting and stealing data.
