Question: In the context of describing telecommunication services in a Public Land Mobile Network (PLMN), what two primary categories of attributes are used to define service characteristics at the point of customer access?
Option 1: Network Capacity Attributes and Device Compatibility Attributes
Option 2: Technical Attributes as seen by the customer, and Operational/Commercial Attributes associated with service provision
Option 3: Service Quality Attributes and Infrastructure Cost Attributes
Option 4: User Experience Attributes and Regulatory Compliance Attributes
Explanation: This is correct because attributes are categorized into those technically visible to the customer (e.g., call setup time, voice quality) and those related to operational and commercial aspects of providing the service (e.g., billing models, service availability), comprehensively defining service characteristics from both user and provider perspectives.
