A,D.

Answer A is not properly worded but correct.

ESXi 6.5 can use 4K AF disks if they use 512e (e=emulation, the physical size of the sectors is 4096 bytes but logically the drive presents sector sizes of 512 bytes. The 4K drive is pretending to be an older 512 one.).
True 4K AF drives where both the physical and logical sector size is 4K is currently not supported in any current release of vSphere/vSAN.
Answer D is also correct – automated UNMAP is a great new feature.
See page 33 of the ‘What’s New in VMware vSphere 6.5 Technical White paper’ for more data regarding the above two answers and other storage enhancements.
But if you want to be literal, then answer B is a better fit than answer A.
512e was already supported in vSphere 6.0 for RDM though.
“Do current GA versions of vSphere and VSAN support 4K Native drives?
No. 4K Native drives are not supported in current GA releases of vSphere and vSAN.”

This has to be B, D.
