In strangler mitigation, which format line contains the SSN used for comparison with the end-of-message validation number?

• A. Line 2
• B. Line 1
• C. Line 3
• D. Line 4

Answer: (A)

The message format uses a fixed, line-based layout for the validation step, and the SSN used for the comparison is defined to be on the second line. Placing the SSN on that line keeps the header and surrounding metadata on the first line, while the rest of the message (including other payload data and the end-of-message validation number) sits on the later lines. The validation process is designed to pull the SSN from the second line to perform its comparison with the end-of-message validation number, so the second line is the one used for this check. When parsing, extract the second line to obtain the SSN for verification.
