In a core-edge architecture, which of the following FC switches would be used for the core?

A gateway typically facilitates connectivity between different network types or protocols, such as Fibre Channel over Ethernet (FCoE) and native FC, rather than acting as a core FC switch.

A bridge operates at Layer 2 of the OSI model and typically connects two network segments, which is not the function of a core switch in a large Fibre Channel SAN.

A router operates at Layer 3 and forwards IP packets between different IP networks, which is fundamentally different from the function of a Fibre Channel switch in a SAN.

A director is a high-performance, chassis-based Fibre Channel switch designed for the core layer of a large Storage Area Network (SAN). Directors offer high port counts, redundant components, and advanced features for scalability and reliability, making them ideal for connecting multiple edge switches and providing high-bandwidth interconnections.
