Question: What is the primary purpose of the `+CE5EASD` AT command in the context of edge enabling layer operation in a User Equipment (UE)?
Option 1: To initiate an ACR procedure for edge application protocol specification
Option 2: To enable or disable notifications for a list of EEC services available at the edge enabling layer
Option 3: To request the UE identifier API procedure from the edge enabling layer
Option 4: To provide the edge enabling layer with an application client profile and optionally EAS discovery filter(s) for EAS discovery
Explanation: The correct answer is Option 4 because the `+CE5EASD` command is specifically designed to equip the edge enabling layer with essential configuration elements (an application client profile and optional EAS discovery filters) necessary for performing Edge Application Server (EAS) discovery by the Mobile Terminal (MT). This aligns with the protocol specifications outlined in relevant 3GPP technical standards, highlighting its role in configuring the UE for effective edge application interactions.
