Question: Which of the following statements is true regarding the European Union Warning System (EU-Alert) in the context of E-UTRAN?
Option 1: EU-Alert utilizes unique Alerting Scenarios (AS) mechanisms distinct from those used by Cell Broadcast Message Alert (CMAS).
Option 2: The E-UTRAN procedures defined for Cell Broadcast Message Alert (CMAS) are equally applicable to EU-Alert due to shared AS mechanisms.
Option 3: EU-Alert is designed exclusively for single, sequential warning notifications within the E-UTRAN network.
Option 4: Implementation of EU-Alert in E-UTRAN requires supplementary specifications beyond those outlined for CMAS.
Explanation: This is correct because EU-Alert shares the same Alerting Scenarios (AS) mechanisms with Cell Broadcast Message Alert (CMAS), making the E-UTRAN procedures defined for CMAS equally applicable to EU-Alert, highlighting the technical alignment between these two systems in public warning delivery over cellular networks.
