Question: In a Network Rejection Event (EVENT DOWNLOAD) from ME to UICC, as per USIM Application Toolkit specifications, which data object is conditionally included based on the rejection of an EMM ATTACH or TRACKING AREA UPDATE request?
Option 1: Access Technology
Option 2: Update/Attach/Registration Type
Option 3: Location Information (MCC, MNC, and LAC)
Option 4: Extended Rejection Cause Code
Explanation: The Extended Rejection Cause Code data object is specifically mentioned to be included only when the ME receives an EMM ATTACH REJECT or a TRACKING AREA UPDATE REJECT message, making it conditionally present based on these specific rejection types. This highlights its role in providing detailed rejection causes for certain network attachment/update failures in telecom networks.
