IT Specialist – Software Development Practice Test

The idea being tested is how a loop can keep executing as long as a condition holds true, which is exactly how a while loop works. A while loop checks its condition before each iteration. If the condition is true, it runs the loop body, then checks the condition again. It repeats this cycle as long as the condition stays true, and stops once the condition becomes false. This guarantees repeated execution only while the specified condition remains true, and it can even lead to an infinite loop if the condition never becomes false.

Other options aren’t loop constructs: Xml is a markup language for organizing data, not a control flow structure; Update is not a looping construct; Trigger is a database feature that runs in response to data changes, not something that repeats based on a condition.
