Question: In a 5G Core (5GC) network, how is the DNS subdomain for a node constructed based on the Mobile Network Code (MNC) and Mobile Country Code (MCC)?
Option 1: node.mnc<MNC>-mcc<MCC>.5gc.org
Option 2: 5gc.node.mnc<MNC>mcc<MCC>.org
Option 3: mnc<MNC>.mcc<MCC>.node.5g.net
Option 4: node.5gc.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Explanation: The correct construction of the DNS subdomain for a 5GC node involves adding the label 'node' to the beginning of the Home Network Domain for 5GC, structured as `5gc.mnc<MNC>.mcc<MCC>.3gppnetwork.org`, ensuring uniqueness and operator control for safe DNS record provisioning. MNC and MCC are integral for network identification, with `<MNC>` and `<MCC>` as placeholders for actual code values.
