Question: In a 5G Network, when applying isolation requirements to managed resources using the NRM (Network Resource Model), what does specifying the `resourceType` as "MANAGED_FUNCTION" typically imply for the scope of isolation?
Option 1: It applies isolation rules across all Network Services (NS) within the core network.
Option 2: It targets the isolation of specific managed function instances, potentially affecting user plane data for slices of a particular tenant.
Option 3: It automatically sets the `isolationRule` to "SHARED" for all resources in the network.
Option 4: It has no impact on the core network, only affecting Radio Access Network (RAN) resources.
Explanation: Specifying the `resourceType` as "MANAGED_FUNCTION" indicates that the isolation requirements are focused on specific instances of managed functions. This could involve isolating user plane data in the core network for slices belonging to a particular tenant, as illustrated in the example. This level of granularity is crucial for ensuring tailored security and performance in multi-tenant 5G environments.
