A host cannot connect to the namespace configured on an NVMe-enabled SVM.

NVMe access in ONTAP is controlled throughNVMe subsystems, not igroups. A namespace must be explicitly mapped to a subsystem to allow host access. If the namespace is not added to the subsystem, the host cannot discover or connect to it.

Additionally, NVMe access control relies onNQNs (NVMe Qualified Names). If the subsystem is configured with an incorrect host NQN, authentication fails and the host is denied access.

Igroups are used for iSCSI and FC, not NVMe, making options B and C incorrect.

Therefore, the correct answers areA and D.
