A is corrent because a value-added network is a privately owned network that routes EDI transactions and alleviates problems related to differences between various organizations’ hardware and software. B is incorrect because a value-added network is likely to have no effect on data redundancy. C is incorrect because a value-added network results in communications to the value-added network, and then to the trading partner. D is incorrect because a value-added network is likely to increase the cost of EDI, not decrease it.
