Alteryx Foundation Micro-Credential Practice Exam

Which of the following are four different integer datatypes?

1. 0 to 255

2. 256 to 512

3. 0 to 1000

4. -128 to 127

The correct answer is: 0 to 255

The correct choice represents a specific range of values associated with a particular integer datatype in Alteryx. In this context, the range from 0 to 255 corresponds to an 8-bit unsigned integer, which is a common datatype used to represent byte-level data. This datatype can store values from 0 to 255, which encompasses a total of 256 distinct integer values. In contrast, the other choices either describe integers that do not correspond to specific datatypes per standard definitions in programming or data analysis. The ranges provided in those options may refer to non-standard or less common representations or might not specifically denote recognized datatypes with the prescribed bit-size allocations typical in environments like Alteryx. Understanding integer ranges and their corresponding datatypes is vital in data manipulation and storage, as it directly impacts memory usage and processing performance. Recognizing the standardized ranges of datatypes allows for better design and implementation of data workflows.
