In MasterCard, how is the Data Transport Network defined?

The Data Transport Network (DTN) in MasterCard is defined as a channel for information exchange. This network facilitates the transfer of data between different entities, such as financial institutions, merchants, and payment processors. The primary function of the Data Transport Network is to ensure that payment transactions are securely and efficiently transmitted across the network, supporting the overall payment ecosystem.

By serving as an information exchange channel, the DTN enables real-time processing of transactions, ensuring that data flows to the right destinations in a timely manner. This network plays a critical role in financial transactions, requiring a reliable and secure framework for data transfer to maintain the integrity and confidentiality of sensitive information.

Other options, such as a method of storing data, a financial database, or a security system for data, do not accurately represent the primary purpose of the Data Transport Network, which is focused on facilitating the exchange of information rather than storage or outright security measures.
