Question: In a Mobile Equipment (ME) with an allocated and activated MExE Service (n°49) and MExE ST service n°1 (EFORPK), what action does the ME take after identifying the files containing certificate instances in EFORPK?
Option 1: The ME automatically installs the certificates without further commands.
Option 2: The ME sends a confirmation message to the network before proceeding.
Option 3: The ME skips assembling the complete certificate instance data if partially available.
Option 4: If necessary, the ME performs READ BINARY commands on these files to assemble the complete certificate instance data.
Explanation: According to the procedure for handling EFORPK (Operator root public key) in MExE services, after identifying relevant files, the Mobile Equipment (ME) gathers all parts of certificate instances. If a certificate is not fully available in EFORPK, the ME initiates READ BINARY commands to collect and assemble the complete data set, ensuring it has all necessary information for further secure operations.
