Question: What should be used as the trailing part of the FQDN of the target NF when routing HTTP/2 request messages to an NF in a different SNPN?
Option 1: The MCC of the serving network
Option 2: The Home Network Domain of the SNPN
Option 3: A locally assigned NID
Option 4: A randomly generated string
Explanation: According to the 3GPP specification, when routing HTTP/2 request messages to an NF in a different SNPN, the FQDN of the target NF should have the Home Network Domain of the SNPN as the trailing part. This ensures proper routing and identification of the target NF within the different SNPN.
