Question: What is the required data type for the MCPTT-ID Attribute Value Pair (AVP) in Diameter data management applications, and what format should its content adhere to?
Option 1: Integer, containing a numerical identifier as per specifications
Option 2: UTF8String, containing an Uniform Resource Identifier (URI) as defined by IETF standards
Option 3: Grouped, comprising both a prefix and flags for identification purposes
Option 4: OctetString, holding a binary representation of the identifier
Explanation: The correct answer is Option 2 because the MCPTT-ID AVP must be of type UTF8String and contain an URI, ensuring interoperability and consistency in identifying resources. This accommodates the variable nature of URIs while enhancing compatibility across systems by adhering to IETF standards.
