During a full-scope security assessment, which of the following is a prerequisite to social engineer a target by physically engaging them?

Locating emergency exits is a physical reconnaissance activity that may support a broader assessment but is not a prerequisite specific to socially engineering a target.

A pretext is a fabricated story, identity, or scenario that the attacker prepares in advance to justify their presence and manipulate the target into compliance. Without a believable pretext, the attacker has no basis for the social engineering interaction and would be unable to establish credibility or elicit sensitive information. It is a foundational prerequisite that must exist before any physical engagement with the target occurs.

Shoulder surfing is a passive observation technique used to capture information such as credentials, and it is a tactic that occurs during engagement rather than a prerequisite before it.

Tailgating is a physical bypass technique used to gain unauthorized access by following someone through a secured entry, which is itself an action taken during engagement and not a preparation step.
