Question: In the context of the SIM-ME interface, what is the primary purpose of executing the 'Ask Random Task' prior to updating the Shared Secret Data (SSD)?
Option 1: To validate the ME's ESN for authentication purposes.
Option 2: To generate a new set of Shared Secret Data (SSD_A_NEW, SSD_B_NEW) directly.
Option 3: To verify the integrity of the RANDSeed value before proceeding.
Option 4: To generate the RANDBS random value, which is a prerequisite for updating the SSD.
Explanation: The correct answer is Option 4 because the 'Ask Random Task' is specifically used to generate the RANDBS random value. This task must be executed before updating the Shared Secret Data (SSD), indicating that generating RANDBS is a necessary step in the SSD update process, likely for security or cryptographic purposes.
