Question: In a USIM application, when a terminal requests an image, what action does it take after identifying the files containing the image instances in EFIMG (Elementary File for Image)?
Option 1: The terminal directly displays the identified file contents as the complete image.
Option 2: The terminal performs READ BINARY commands on these files to assemble the complete image instance data.
Option 3: The terminal sends a confirmation message to the USIM before proceeding with the image assembly.
Option 4: The terminal automatically updates the EFIMG file after identifying the required image instances.
Explanation: According to the specified process for handling image requests in the context of a USIM application, once the terminal identifies the files containing the image instances within the EFIMG, it must assemble these parts into a complete image. This is achieved by executing READ BINARY commands on the identified files, ensuring the terminal can correctly reconstruct and potentially display or utilize the full image instance data.
