This question requires identifying the architecture type based on the SWIFT CSP Architecture Types (defined in CSCF documentation) for a user with an sFTP server pushing files to an outsourcing agent hosting the Communication Interface:
Step 1: Define the Scenario
The SWIFT user uses an sFTP server to transfer files to an outsourcing agent, which hosts the user’s Communication Interface (e.g., SWIFT Alliance Gateway). The Communication Interface connects to the SWIFT network.
Step 2: SWIFT Architecture Types Overview
A1: Full in-house stack (Messaging Interface, Communication Interface, etc.).
A3: Communication Interface hosted by a service provider/outsourcing agent; back-office or middleware connects to it.
A4: Both Messaging and Communication Interfaces hosted by a service provider.
B: Alliance Lite2 (direct cloud-based connectivity).
[Reference: CSCF v2024, Appendix A – Architecture Types., Step 3: Match the Scenario, The outsourcing agent hosts the Communication Interface, and the user pushes files via sFTP (likely from a back-office or middleware system). This matchesA3, where the Communication Interface is outsourced, but the user retains control over file generation and transfer systems interfacing with it., A1 is incorrect (no full in-house stack), B is irrelevant (not Alliance Lite2), and A4 doesn’t apply (Messaging Interface isn’t mentioned as outsourced)., Conclusion: The architecture type is A3, as the Communication Interface is hosted by an outsourcing agent., Reference: CSCF v2024, Architecture Type A3 Definition; SWIFT CSP FAQ., ]
