In the architectural framework of modern interbank payment systems, a participant bank initiates a high-value transaction through the Structured Financial Messaging System (SFMS). Which of the following networking components or protocols is primarily responsible for ensuring that the data packets are delivered in the correct sequence and without any loss or duplication across a wide area network connecting various bank nodes?
- 1The Address Resolution Protocol (ARP) which maps the logical IP address of the destination bank server to its physical Media Access Control address.
- 2The User Datagram Protocol (UDP) which facilitates faster transmission by eliminating the overhead of handshaking at the cost of delivery assurance.
- 3The Transmission Control Protocol (TCP) which resides at the Transport Layer of the OSI model and provides reliable, connection-oriented end-to-end data delivery.✓
- 4The Border Gateway Protocol (BGP) which manages the routing path selection between different autonomous systems.
Correct answer
The Transmission Control Protocol (TCP) which resides at the Transport Layer of the OSI model and provides reliable, connection-oriented end-to-end data delivery.
