Question: What is the primary concern for network operators when deploying a network that serves only a subset of vertical industries and services in a 5G system?
Option 1: Ensuring seamless handover between different network slices.
Option 2: Preventing end-users from accessing all new services and capabilities via 5G systems.
Option 3: Guaranteeing Quality of Service (QoS) for all subscribers regardless of the network slice used.
Option 4: Minimizing capital expenditures on infrastructure deployment.
Explanation: The correct answer is Option 2 because, according to the text, one of the primary concerns is that an operator's decision to deploy a network serving only a subset of vertical industries and services should not prevent end-users from accessing all new services and capabilities via 5G systems. This implies that ensuring access to all services for end-users is crucial, making Option 2 the correct answer.
