Question: What is a key exception when applying the general NF certificate profile requirements to SEPP inter-domain certificate profiles for inter-PLMN domains?
Option 1: The validity period of the certificates
Option 2: The contents of the Subject DN field and the subjectAltName field
Option 3: The encryption algorithms used for certificate signing
Option 4: The organizational identity of the Certificate Authority
Explanation: For SEPP inter-domain certificate profiles in an inter-PLMN (Public Land Mobile Network) context, while most requirements mirror those of the general NF (Network Function) certificate profile, there is a notable exception regarding the specifics of two fields: the Subject DN (Distinguished Name) field and the subjectAltName field. These exceptions are defined to accommodate interoperability and security standards specific to inter-PLMN scenarios, as further detailed in guidelines like those from the GSMA (Groupe Speciale Mobile Association). This distinction is crucial for ensuring seamless and secure communication between different PLMNs.
