Question: In SMS routing using 8-bit address port addressing, what happens to an information element with a Destination Port value within the range of 0-239 when received by a device?
Option 1: The device processes it as a high-priority message.
Option 2: The receiving entity ignores it and commences processing at the next information element.
Option 3: The device allocates a new available port from the range of 240-255 for the application.
Option 4: The message is automatically forwarded to a default application.
Explanation: According to SMS standards, port numbers 0-239 are reserved. When a receiving entity encounters an information element with a port value within this reserved range (or any unsupported value), it ignores that element and begins processing at the next information element, ensuring compatibility and preventing potential conflicts.
