What is a recommended design choice in a topology for multipathing iSCSI traffic?

The correct answer is C. initiators and targets in separate subnets. You can create multiple paths by configuring multiple ports and target portals on different IP subnets. By keeping initiator and target ports in different subnets, you can force ESXi to create paths through specific ports. In this configuration, you do not use port binding…

Explanation

You can create multiple paths by configuring multiple ports and target portals on different IP subnets. By keeping initiator and target ports in different subnets, you can force ESXi to create paths through specific ports. In this configuration, you do not use port binding because port binding requires that all initiator and target ports are on the same subnet. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID- 4C19E34E-764C-4069-9D9F-D0F779F2A96C.html
