Q: 1 You are employed as a database developer at ABC.com. You make use of SQL Server 2008 to develop database strategies. You are in the process of developing a strategy that has three tables named ABC1, ABC2, and ABC3. The ABC1 and ABC2 have the integer and varchar data type column types configured respectively. ABC3 has both the integer and varchar data types configured as column types. You have configured rowlevel compression on ABC1, and page-level compression on ABC2 and ABC3. Which of the following describes the reason for this configuration? A. It allows for the reduction of disk space usage, while modifying the data types in the tables of the database B. It allows for the reduction of disk space usage without modifying the data types in the tables of the database C. It allows for the increase of disk space usage, while modifying the data types in the tables of the database D. It allows for the increase of disk space usage, while modifying the data types in the tables of the database Answer: B

Q: 2 You are employed as a database developer at ABC.com. You make use of SQL Server 2008 to develop database strategies. You have received instructions to design a database strategy that includes a table which hosts data imported from an outside source. This data includes a field named TransactionTime that should be configured to make use of hh:mm:ss[.n] format. You have been informed that the data type selected for the TransactionTime field must allow for storage to be kept to a minimum. You, therefore, make use of the time(1) data type. Which of the following is TRUE with regards to the time data type?


A. The default fractional precision is 7 (100ns). B. The default fractional precision is 3 (100ns). C. The time produced by the time data type is not time zone aware and is based on a 24-hour clock. D. The time produced by the time data type is time zone aware and is based on a 12-hour clock. Answer: A,D

Q: 3 You are employed as a database developer at ABC.com. You make use of SQL Server 2008 to develop database strategies.

You have configured a foreign key constraint between the ABCVendor and ABCItem tables on the ABCVendorID column. You have configured the ABCVendor table to display a 0 value for the ABCVendorID when a vendor is removed. You also want make sure that the ABCVendorID value in the ABCItem table is set to 0 when a vendor is removed. You then create a default constraint on the ABCVendorID column in the ABCItem table, which is used to set the value to 0. Which of the following actions should you take NEXT? A. You should consider setting the ON DELETE property of the foreign key constraint to Null. B. You should consider setting the ON DELETE property of the foreign key constraint to Default. C. You should consider setting the ON DELETE property of the foreign key constraint to Cascade. D. You should consider setting the ON DELETE property of the foreign key constraint to No Action. Answer: B

You have received instructions to design a strategy that helps ABC.com’s administration manager. You have created three entities named User, UserTask, and UserAssignment. You have configured the User entity to make use of the UserID attribute, the UserTask entity to make use of the UserTaskID attribute, and the UserAssignment entity to make use of the UserAssignmentID attribute. You have been informed that the strategy must allow for users to be assigned multiple tasks. You also need to ensure that a task is deleted when it has been completed, and that the assignment linked to that task is also deleted. Furthermore, a NULL value has to replace the user reference to the user assignment as soon as a user becomes unavailable to finish a task. Which combination of the following actions should you take? (Choose all that apply.) A. You should consider configuring Foreign Key constraints on the UserTaskID and UserID attributes in the UserAssignment entity. B. You should consider configuring Foreign Key constraints on the UserTaskID and UserID attributes in the UserTask and User entities respectively. C. You should consider referencing the UserTask and User entities respectively. D. You should consider referencing the UserAssignment and User entities respectively. E. You should consider specifying the On Delete property as NULL. F. You should consider specifying the On Delete property as Default.
