Question: Which of the following QoS Class Identifiers (QCIs) can be included in the EPS-Subscribed-QoS-Profile for a default bearer over specific interfaces?
Option 1: QCI_5, associated with non-GBR bearers
Option 2: QCI_1, associated with GBR bearers
Option 3: QCI_7, associated with Delay-Critical GBR bearers
Option 4: Any QCI value (QCI_1 to QCI_9) without restrictions
Explanation: Only QoS-Class-Identifier values associated with non-GBR (Guaranteed Bit Rate) bearers can be sent, making QCIs like QCI_5 permissible due to their association with non-GBR bearers.
