C.

Correct: B (It’s obvious, HANFS use NFS on ACFS-only filesystem located at ASM disks)
Correct: D https://docs.oracle.com/database/121/OSTMG/GUID-4D7A5911-8FA6-47DC-98BB-593B2C90D43E.htm#OSTMG95489

Wrong: A – HANFS depends on NFS stack
Wrong: C – I think HANFS provides high availability in case of an NFS SERVER failure. (HAVIP will be move to second NFS at another cluster member). I can’t imagine how HANFS may provide HA for NFS client..
Wrong E: The initial processing of srvctl add havip ensures that: The address being used is static, not dynamic Any DNS names resolve to only one host, not round-robin multiple DNS resolutions
