Exam 5V0-21.20 topic 1 question 17 discussion

A vSAN administrator is working on a 4 host homogenous vSAN Cluster that has 2 disk groups per host. One of the hosts needs to be permanently removed and repurposed for some other use.
These are the out of order steps which need to be completed:
1. Delete the disk group(s) that reside on the host you want to decommission.
2. Wait for resync traffic to complete and the host to enter maintenance mode.
3. Ensure there is sufficient capacity in the vSAN disk groups to decommission a node.
4. Put the host into maintenance mode with full data migration selected.
5. Move the ESXi host out of the cluster.
What is the correct order?
