PY103.16 Physical Security Practice Test

In a physical protection system, detection is the sensing step: sensors identify something unusual and generate an alarm or event. Assessment is the next step, where you evaluate how serious that event is and decide what action to take—who to alert, how to respond, and what remediation or containment is needed. This option matches that flow by saying detection triggers events, and assessment determines both the seriousness and the appropriate actions to take. It captures the idea that detection flags something, while assessment translates that flag into a measured response. The other choices misrepresent the role of assessment (for example, limiting it to costs or only deciding seriousness) or misstate what detection does (such as reporting to external agencies, which isn't a core PPS function).
