질문 # 112
Which task is accomplished by an IT professional organization?
정답：A
설명：
Publishing professional journals is a common task accomplished by IT professional organizations. In Information Technology, organizations such as ACM and IEEE publish peer-reviewed journals, magazines, conference proceedings, and technical standards that help share research, best practices, and emerging developments. These publications support professional learning, improve the quality of practice, and help define the body of knowledge for the field. Coordinating data exchange policies between states is more likely a government or intergovernmental function. Producing government regulations is the role of regulatory agencies, not professional associations. Brokering international trade agreements is handled by governments and international trade bodies rather than IT professional organizations. Professional organizations typically provide conferences, certifications or professional development programs, codes of ethics, special interest groups, and publications. Since journals and technical publications are a standard output of professional associations, the correct answer is publishing professional journals.

질문 # 114
A person is updating procedures for handling integer data within a database. Which value is an example of this data type?
정답：C
설명：
Integer data is a numeric data type used to store whole numbers without fractional or decimal parts. In Information Technology and database systems, integers are commonly used for counts, quantities, identifiers, and values that naturally occur as whole numbers. The value "the number of baseball games in a season" is a count and is expressed as a whole number, making it a clear example of integer data. By contrast, 3.14159 includes decimal places and is typically stored as floating-point or decimal data rather than integer. A single keystroke is character data because it represents a symbol such as A or 7, not a quantity. Whether a bank account does or does not have money in it is a two-state condition and is best represented as Boolean data, such as true or false. Using correct data types improves storage efficiency, supports accurate validation rules, and helps ensure correct query behavior. Therefore, the correct example of integer data is the number of baseball games in a season.
