A network architect is designing a storage network to connect to an existing IP network over 100G Ethernet ports for multiple hosts. The architect decided to require iSCSI multipathmg to provide multi

iSCSI multipathing relies on the ability of the underlying IP network to utilize multiple paths between the initiator and target for both redundancy and performance. Equal-Cost Multi-Path (ECMP) routing enables the IP network switch to distribute iSCSI traffic across multiple available, equally-costed paths to the storage devices, facilitating load sharing and fulfilling the multipathing requirement.

VLAN load balancing is not a standard network routing or switching mechanism to achieve load sharing for multipathing; VLANs provide network segmentation, not path distribution across equal-cost routes.

While multiple physical connections are essential for iSCSI multipathing, this is a connectivity design aspect rather than a specific configuration requirement on the IP network switch for how it handles and load-shares traffic across those paths.

A trunk configuration allows multiple VLANs over a single physical link, which is common for iSCSI, but it does not directly facilitate load sharing across multiple distinct physical routes for multipathing on the IP network layer.
