Question: What is the purpose of access class control in the Evolved Packet System (EPS) network?
Option 1: To prioritize traffic for certain groups of User Equipment (UEs)
Option 2: To restrict access for certain groups of UEs by barring their access class
Option 3: To manage Quality of Service (QoS) for specific applications
Option 4: To authenticate and authorize UE access to the network
Explanation: The correct answer is Option 2 because the paragraph states that the network can restrict access for certain groups of UEs by means of barring their access class, which is the primary purpose of access class control in EPS.
