Question: What is the data type of the MIC (Message Integrity Check) AVP associated with a discovered ProSe Application Code in Inter-Proximity-services (Prose) function signalling aspects?
Option 1: OctetString
Option 2: Unsigned32
Option 3: Integer64
Option 4: UTF8String
Explanation: The correct answer is Option 1 because, according to the specifications for Inter-Proximity-services (Prose) function signalling aspects, the MIC AVP is explicitly defined as being of type OctetString. This data type is suitable for containing a Message Integrity Check associated with a discovered ProSe Application Code, ensuring the integrity of the message in telecom networks. In contrast, Unsigned32 is used for counters, and Integer64 and UTF8String are not specified for this particular use case.
