Explanation:
THE SUPPLIED ANSWER IS CORRECT.
FOR 3 STEPS USE
1. SETUP/PREPARESCHEMA
2. SETUP/PREPAREAD
3. SETUP /PREPAREDOMAIN
However, the answer only provides for 2 steps.
If you run setup /preparead then this command checks to see if the schema extensions have been installed and if not, then it proceeds to install them.
Hence setup /preparead is correct, a trick question from Microsoft to check if you know how setup / preparead actually operates.
