In the same subnet, when configuring NNI port attributes, the IP addresses of the ports at both ends of different links can be repeated.
The correct answer is A. True. Option A is correct because NNI (Network-to-Network Interface) port configurations treat each physical link as an independent point-to-point connection.

Explanation
Option A is correct because NNI (Network-to-Network Interface) port configurations treat each physical link as an independent point-to-point connection. Within the same subnet, different links are distinguished by their link identifiers rather than requiring globally unique IP addresses across all NNI ports, so the same IP address can legitimately appear on ports of multiple different links. Option B is incorrect because it incorrectly assumes that standard IP uniqueness rules (where every device in a subnet must have a unique address) apply universally to NNI port addressing - NNI configurations specifically permit this address reuse across separate links. Memory tip: think of each NNI link as its own isolated "tunnel" - two different tunnels can have the same endpoint address labels because they never directly communicate with each other.
