Explanation:
An Academic Database deals with the information pertaining to the records of students of an institute. The various fields which can be associated with a student are Name, Unique Identification Number, Marks in various subjects, Grades, Courses Taken and so on. Most of the fields mentioned above have some or other form of validation that is required for the DB to be consistent and follow the basic properties of a database.
One field where range validation can be used is MARKS. In the marks field, the range of marks will be say 0 to 100 and anything below 0 or above 100 must be reported to the database administrator. Another field where we can apply a range validation is AGE in which the range of age allowed could greater than say 10, if it is a college and maximum age could be say 60. Thus, the range check on the AGE field is 10 to 60.
One field where choice validation can be used is GENDER. In the gender field, there could be multiple choices like Male, Female and Others. Thus, out of the available choices we have to select only the available choice and only one choice must be selected where we can apply choice validation. Another field is COURSE, where we can have a list of courses a student can opt for and out of the available courses can select one.
Thus, there are multiple fields where we can apply various types of validation and it is important to explore the area for which the DB has been created understanding all the scenarios and attributes of the problems that are associated with that area.
Answer:
The contents of shared folders might include both programs and data files. Common files may be stored and accessed using shared application folders, which simplify administration and offer a single area for users to store and access common data. If all data files are consolidated in a single shared folder, users will have an easier time finding them.

Answer:
EFS cannot store files encrypted.
Explanation:
EFS) is a feature introduced in version 3.0 of NTFS that provides filesystem-level encryption. EFS is useful for mobile computer users, whose computer are subject to physical theft, and for storing highly sensitive data. Encryption itself is the method where the information is converted into secret code that hides the information's true meaning. (EFS) is used to encrypt files and folders. EFS is easy to use, with nothing more than a check box in a file’s properties. It is not fully supported on Windows 7 Starter, Windows 7 Home Basic, and Windows 7 Home Premium!
I’d say both techies are correct.
Volatility, as applied in gasoline, is quantified by the tendency of the liquid to change to vapor at any given temperature (vaporize). This rate of change might be hard or easy, this depends on the temperature or the pressure. Technician B is also correct. RVP is defined and determined experimentally according to the ratio of the vapor volume to the liquid volume at 100 °F.
