You need to meet the following requirements: Avoid losing existing permissions on existing objects

DRAG DROP
You administer a Windows Azure SQL Database database used for data warehouse operations.
The database contains a table named OrdersHistory, defined as follows:

A weekly ETL (extract-transform-load) runs a large INSERT statement to add data into the
OrdersHistory table. The process is taking a long time to complete. You discover that the
bulk of the process is performing non-clustered index updates on the OrdersHistory table.
You need to improve the performance of the ETL process faster. You need to meet the
following requirements:
Avoid losing existing permissions on existing objects.
Use minimal administrative effort.
What should you do? (To answer, move the appropriate actions from the list of actions to the

Answer: See the explanation.

Explanation:
Box 1:

Box 2:

Box 3:

Note:
* Drop and rebuild the index, then run the insert statement.
* Rebuilding an index can be executed online or offline. Reorganizing an index is always
executed online. To achieve availability similar to the reorganize option, you should rebuild
indexes online.
Incorrect:
* Dropping and rebuilding the OrdersHistory table would lose the permissions on this table.
* The SELECT INTO statement creates a new table and populates it with the result set of the
SELECT statement.
