1. You are developing a database application by using Microsoft SQL Server 2012. An application that uses a database begins to run slowly. Your investigation shows the root cause is a query against a read-only table that has a clustered index. The query returns the following six columns: * One column in its WHERE clause contained in a non-clustered index * Four additional columns * One COUNT (*) column based on a grouping of the four additional columns.
You need to optimize the statement. What should you do?

A) Add a columnstore index to cover the query.

C) Enable the optimize for ad hoc workloads option.
D) Include a SET STATISTICS PROFILE ON statement before you run the query.
E) Add an INCLUDE clause to the index.
F) Include a SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement before you run the query.
G) Include a SET FORCEPLAN ON statement before you run the query.
H) Add a LOOP hint to the query.
I) Add a FORCESEEK hint to the query.
J) Include a SET TRANSACTION ISOLATION LEVEL REPEATABLE READ statement before you run the query.
K) Add a HASH hint to the query.
L) Cover the unique clustered index with a columnstore index.
M) Add a FORCESCAN hint to the Attach query.
N) Include a SET STATISTICS SHOWPLAN_XML ON statement before you run the query.

You have multiple queries that read data and produce reports from the database. You need to offload the reporting workload to the secondary replica when HA/Server01 is the primary replica. What should you do?

CREATE TABLE Inventory (
ItemID int NOT NULL PRIMARY KEY,
ItemsInStore int NOT NULL,
ItemsInWarehouse int NOT NULL)
You need to create a computed column that returns the sum total of the ItemsInStore and ItemsInWarehouse values for each row. The new column is expected to be queried heavily, and you need to be able to index the column. Which Transact-SQL statement should you use?

A) ALTER TABLE Inventory ADD TotalItems AS SUM(ItemsInStore, ItemsInWarehouse)
B) ALTER TABLE Inventory ADD TotalItems AS ItemslnStore + ItemsInWarehouse
C) ALTER TABLE Inventory ADD TotalItems AS ItemsInStore + ItemsInWarehouse PERSISTED
D) ALTER TABLE Inventory ADD TotalItems AS SUM(ItemsInStore, ItemsInWarehouse) PERSISTED
