Question 1 of 30

A retail outlet\'s POS terminal, operating under the ISO 8583:2003 standard, fails to receive a definitive authorization response from the issuer due to an intermittent network failure. The terminal\'s operator observes that the system then attempts to process the transaction using pre-configured offline parameters. Which combination of ISO 8583:2003 fields, when analyzed by the acquirer, would most strongly suggest this operational shift in response to a communication breakdown, implying the terminal\'s adaptive behavior?

Field 39 (Response Code) indicating an unavailability error, coupled with a repeated Field 11 (System Trace Audit Number - STAN) from a previous, unconfirmed transaction attempt.

Field 41 (Card Acceptor Terminal ID) showing a valid terminal identifier and Field 42 (Card Acceptor ID Code) confirming the merchant's identity.

Field 3 (Processing Code) specifying a standard purchase transaction and Field 12 (Time, Local Transaction) showing a recent timestamp.

Field 70 (Network Management Information Code) being present and Field 60 (Custom Private Use Field) containing a vendor-specific status code.
