What best describes the scenario where employees receive a call about a survey that is suspected to be a scam?

Vishing, or voice phishing, specifically refers to phishing attacks conducted through phone calls. In this scenario, employees are receiving a call about a survey that raises suspicions of being a scam. This aligns perfectly with the characteristics of vishing as it involves an attempt to extract sensitive information or manipulate individuals under the guise of an official-sounding inquiry.

Phishing typically occurs via email, where malicious actors attempt to trick individuals into providing personal information. Whaling is a targeted form of phishing directed at high-profile individuals, like executives, which is not relevant here since the scenario describes a general call to employees rather than targeting specific individuals. Social engineering encompasses various tactics used to manipulate people into divulging confidential information, but in this case, the specific method of deception via phone calls clearly categorizes it as vishing.
