Question: Which of the following statements is true regarding the Korean Public Alert System (KPAS) in the context of E-UTRAN?
Option 1: KPAS utilizes unique Alerting Scenarios (AS) mechanisms distinct from those used by Cell Broadcast Message Alerting Scenarios (CMAS).
Option 2: KPAS supports only a single warning notification at any given time.
Option 3: E-UTRAN procedures for KPAS are entirely unrelated to those defined for CMAS.
Option 4: KPAS employs the same Alerting Scenarios (AS) mechanisms as Cell Broadcast Message Alerting Scenarios (CMAS), making E-UTRAN procedures for CMAS equally applicable.
Explanation: This is correct because, according to the provided context, KPAS uses the same AS mechanisms as CMAS. As a result, the E-UTRAN procedures that have been defined specifically for CMAS are also applicable and effective for KPAS, highlighting the shared technical approach for these public warning systems within the E-UTRAN framework.
