I'm not sure about on-disk locking and 4K native storage devices, but I think it's important to understand all the features for the exam.

I believe on-disk locking and 4K native storage devices are also features supported by VMFS6 datastores.

Absolutely, on-disk locking is a key VMFS6 feature. It helps to improve performance and reliability when multiple VMs are accessing the same datastore.

B) On-disk locking - I'm pretty sure that's also a VMFS6 feature. It allows multiple VMs to access the same VMFS6 datastore concurrently.

Yes, that's correct. VMFS6 supports concurrent access to shared storage, which is a major improvement over VMFS5.

Sounds good to me. I'm feeling pretty confident about this question now. Though I have to say, the exam writers really know how to make these questions tricky!

Okay, so based on our discussion, I think the two VMFS6-only features are A) Concurrent access to shared storage and D) 4K native storage devices. Those seem to be the clear winners here.
