Question: In a Mobile Equipment (ME) with an allocated and activated MExE Service (n°49) and MExE ST service n°2 (EFARPK), what action does the ME take after identifying the file containing the certificate instance in EFARPK?
Option 1: The ME performs READ BINARY commands on the identified file to assemble the complete certificate instance data if necessary.
Option 2: The ME directly uses the identified certificate instance for authentication without further data retrieval.
Option 3: The ME skips analyzing the EFARPK data and proceeds with default certificate settings.
Option 4: The ME initiates a WRITE BINARY command to update the certificate instance in the identified file.
Explanation: After identifying the file, the ME analyzes its data. If necessary (meaning if not all required data is immediately available or complete), it performs READ BINARY commands on this file to assemble the full certificate instance, highlighting a nuanced understanding of telecom's secure data handling practices.
