Which of the following BEST describes the difference between a red team engagement and a penetration test?

This reverses the definitions - it incorrectly attributes APT emulation and broad scope to the penetration test rather than the red team.

Red team engagements are explicitly narrow and objective-focused, not broad; broad scope belongs to penetration tests.

Red team engagements do not focus on vulnerability identification - comprehensive vulnerability discovery is the purpose of a penetration test, not a red team exercise.

A penetration test is designed to maximize coverage, systematically identifying and exploiting as many vulnerabilities as possible across the target environment. A red team engagement, by contrast, operates with a narrow, goal-oriented scope that simulates a realistic advanced persistent threat - testing detection capabilities, response procedures, and the ability to achieve a specific objective such as data exfiltration or lateral movement to a crown jewel asset.
