An attacker sets up a look-alike wi-fi network, tempting unsuspecting users to connect with the attacker's wi-fi network instead. what is this called?

The correct answer: Impersonating a legitimate network

An attacker could impersonate a network by creating a look-alike network to lure unsuspecting users to connect to the attacker’s network. The attacker could do this without using an AP by setting up an ad hoc or peer-to-peer network that connects wireless devices directly to another wireless device. The attacker would give ad hoc network misleading names, such as Free Wireless Network or Free Airport Network. Once the user establishes a connection, the attacker might be able to directly inject malware into the user’s machine or steal data.

Attacks on wireless networks is typically a three-step process: discovering the wireless network, connecting to the network, and launching the attack.
