DRAG DROP
You are building a fact table in a data warehouse.
The table must have a columnstore index. The table cannot be partitioned.
You need to design the fact table and load it with data.
Which three actions should you perform in sequence? (To answer, move the appropriate
actions from the list of actions to the answer area and arrange them in the correct order.)
Answer: 
1. Create Table
2. Load Data
3. Create coloumnstore index

luis is absolutely right. xVelocity is not a requirement for Columnstore indexing. It’s just an option for improving querying on column-wise indexes. An xVelocity memory optimized columnstore index, groups and stores data for each column and then joins all the columns to complete the whole index. This differs from traditional indexes which group and store data for each row and then join all the rows to complete the whole index.
So, you must do the following first even if you want to implement xVelocity-type columnstore indexes…
1. Create the Fact table (the most-basic requirement for data load)
2. Load the data
3. Create the columnstore index.

Actually the index can be prepared before loading data – so the order
1. Create the Fact table (the most-basic requirement for data load)
2. Create the columnstore index.
3. Load the data
is also right

Milen, As per my understanding, you need to load the data first as you cannot change data for Columnstore index.
