Question: What is a key consideration for the size of the SON Transfer Response Container IE in E-UTRAN's S1 Application Protocol (S1AP)?
Option 1: Ensuring it matches the minimum MTU of an Ethernet network
Option 2: Complying with the maximum message size on the Gb interface, dependent on lower layer configurations
Option 3: Adhering to a fixed size of 2048 octets for all network types
Option 4: Guaranteeing it exceeds the typical Frame Relay sub-network limitation for future-proofing
Explanation: The correct answer highlights the importance of compatibility with the maximum message size on the Gb interface, varying based on lower layers used and their configurations. This ensures seamless communication without potential truncation or loss due to size mismatches. The other options are incorrect because they reference unrelated network types, suggest a rigid size, or imply exceeding standard limitations without a practical reason.
