DRAG DROP
Your company has a datacenter in London. Your network contains an Active Directory forest named
adatum.com. The datacenter has a SAN that contains SSD, SAS, and SATA drives. The SAN contains
RAIDO physical partitions and RAID5 physical partitions for each hard disk drive type. You install
System Center 2012 Virtual Machine Manager (VMM) in the datacenter. You need to create 8 LUNs
for each RAID type and disk type. The LUNs must be organized based on the disk type. Which four
actions should you perform from the VMM Administrator Console? (To answer, move the
appropriate actions from the list of actions to the answer area and arrange them in the correct
order.)
Answer: 
Explanation:
You need to already have SMI-S installed before discovering the storage.
Should be:
1. Install SMI-S
2. Discover storage
3. Create Storage Classifications
4. Create LUN’s
There is no need (or ability) to create WMI classes for this.

Much like question 5, why don’t you create the classifications before discovering the storage?
I agree with Blazz.
