You are setting up a new AFF A400 that will serve iSCSI LUNs. You will have four iSCSI SVMs that each need to connect to an Internet Storage Name Service
(iSNS) for discovery and management purposes.
In this scenario, which network interface is needed for each SVM to register with the name service?
To enable an iSCSI Storage Virtual Machine (SVM) to register with an Internet Storage Name Service (iSNS) for discovery and management, the SVM's management LIF is required. The management LIF is specifically designed to handle tasks such as communication with management services, including iSNS. Other types of LIFs, such as node management LIF or intercluster LIF, serve different purposes and are not used for this type of discovery and management.
B is correct answer. See URL: https://docs.netapp.com/ontap-9/topic/com.netapp.doc.dot-cm-sanag/GUID-E0C83978-2139-48C5-8C2B-80F4A385583E.html
B : The iSNS server communicates with each storage virtual machine (SVM) through the SVM management LIF
