Question: What is the primary reason for recommending a maximum record length of 100 bytes for LSA Descriptor files in OTA (Over-The-Air) management?
Option 1: To accommodate multiple LSA IDs and Cell IDs in a single record.
Option 2: To ensure compatibility with older USIM applications.
Option 3: To leave room for command descriptor and signature information in the SMS.
Option 4: To reduce the number of OTA management transactions.
Explanation: In the context of OTA management, efficient use of space within an SMS is crucial. The recommendation for a maximum record length of 100 bytes is primarily driven by the need to accommodate additional metadata (command descriptor and signature information) alongside the LSA Descriptor file within the limited payload of an SMS, ensuring secure and successful transmission.
