Microsoft Transition Your MCITP: Database Administrator 2008 or MCITP: Database Developer 2008 to MCSE: Data Platform Sample Questions:

1. You need to add a new column named Confirmed to the Employees table. The solution must meet the following requirements:
- Have a default value of TRUE.- Minimize the amount of disk space used.
Which code segment should you use?

A) ALTER TABLE Employees
ADD Confirmed bit DEFAULT 0;
B) ALTER TABLE Employees
ADD Confirmed char(1) DEFAULT '0';
C) ALTER TABLE Employees
ADD Confirmed char(1) DEFAULT "1";
D) ALTER TABLE Employees
ADD Confirmed bit DEFAULT 1;

2. You have a SQL Server 2012 database named DB1. You have a backup device named Device1.
You discover that the log file for the database is full.
You need to ensure that DB1 can complete transactions. The solution must not affect the chain of log sequence numbers (LSNs).
Which code segment should you execute?

A) BACKUP LOG DB1 TO Device1 WITH TRUNCATE_ONLY
B) BACKUP LOG DB1 TO Device1
C) BACKUP LOG DB1 TO Device1 WITH COPY_ONLY
D) BACKUP LOG DB1 TO Device1 WITH NORECOVERY

3. DRAG DROP
You administer a SQL Server 2014 instance.
The server is capable of 10000 IO/second (IOPS). During the time period when the second process executes, the disk IO can reach 7000 IOPS, and CPU use can average 30% over the eight processors.
The first process summarizes the day's activity executed by a login of [SummaryReportLogin]. The second process submits transactions executed by a login of [ETLLogin].
A Resource Governor classifier function has been created to return WG_Low for connections from the [ETLLogin] and [SummaryReportLogin].
You need to set up the Resource Group and Workgroup Pools on the instance.
You have the following requirements:
- Both processes must never use more than 50 percent of the CPU at any one time. - The number of active queries that these processes can execute simultaneously should be limited to a maximum of 10. - The SummaryReportLogin process must always achieve the minimum IOPS required to be minimally affected during executing the ETLLogin processes.
Develop the solution by selecting and arranging the required code blocks in the correct order.
You may not need all of the code blocks.

4. You are creating a table named Orders.
You need to ensure that every time a new row is added to the Orders table, a user-defined function is called to validate the row before the row is added to the table.

A) a CHECK constraint
B) a DEFAULT constraint
C) a Data Definition Language (DDL) trigger
