Question: What is the correct format for deriving the Certification Authority server (CA/RA) Fully Qualified Domain Name (FQDN) in a scenario with multiple CA/RA servers, one per vendor?
Option 1: cara.oam.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Option 2: vendor<ViD>.cara.oam.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Option 3: <ViD>.oam.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Option 4: cara.<ViD>.oam.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Explanation: The correct format for deriving the Certification Authority server (CA/RA) FQDN in a scenario with multiple CA/RA servers, one per vendor, is by adding the <vendor ID> label in front of the "cara" label. This ensures that each vendor's CA/RA server has a unique FQDN.
