Correct answer is D : Driver Partnership limit of 64 drives will be reached by the first drive added, then to expand with a newly created Drive Partnership Group, a full RAID Disk Group will need to be added : 12 Drives plus 1 drive for the Parity, plus 1 drive for the Spare Space.

A is correct, add up 1x 15.3 TB 'SAS Flash 4' though not recommended as it takes forever to expand Each drive partnership group can only contain a single drive type, though different sizes of a particular drive type can be mixed within the group Alternatively, D - but will cost $$$ 1x 7.6TB SSD goes into 1 DPG (Max 64 Disk in a DPG) 14x X.XTB SSD (New DPG requires min 'RAID stripe width' plus one; any technology or size) Drive partnership groups (Page 8) https://www.delltechnologies.com/resources/en-us/asset/white-papers/products/storage/h16289-dell_emc_unity-dynamic_pools.pdf

Correct is D - Adding 1x 15.3 TB is possible but only getting usable 7.6 TB out of 15.3 TB disks. Question is to add 10 TB

When you add drives, you must add them in multiples of the selected RAID stripe width. C is correct.
