Question: In a 5G network, what is a required mechanism for utilizing 5G timing resiliency, specifically in relation to external accesses?
Option 1: Verification of authorization for 3rd party applications to utilize 5G timing resiliency.
Option 2: Mandatory implementation of GPS as the primary time source.
Option 3: Regular software updates for all User Equipment (UE) to ensure timing accuracy.
Option 4: Encryption of all data transmitted over the timing resiliency protocol.
Explanation: This is correct because the 5G system must support a mechanism to verify the authorization of 3rd party applications before they can utilize the 5G timing resiliency feature, ensuring security and controlled access to critical network functionalities.
