Validating test questions validating steam cache files

A multiple choice item consists of a problem, known as the stem, and a list of suggested solutions, known as alternatives. A stem that presents a definite problem allows a focus on the learning outcome.

Multiple choice test items are less susceptible to guessing than true/false questions, making them a more reliable means of assessment.

The reliability is enhanced when the number of MC items focused on a single learning objective is increased.

The problem with accepting the parameter is that you can't be certain a function call passes an actual file path.

We are accepting anything that is a string, and we are going to start doing things with that string, trusting that the script user did not make any mistakes when typing in the path. For instance, if your script prompts for a folder path, and the user enters something unexpected, your script won't be able to perform your intended task.

This will also allow us to return helpful error messages to the user in case the path did not pass validation. NET class Invoke-Task -Path C:\Users Invoke-Task : Cannot process argument transformation on parameter 'Path'. You can use built-in Power Shell features to validate user input, or you can write a validate script.

Below I will explain how you can validate parameters in Power Shell with or without the help of validate scripts.

Common student errors provide the best source of distractors. Sophisticated test-takers are alert to inadvertent clues to the correct answer, such differences in grammar, length, formatting, and language choice in the alternatives.

It’s therefore important that alternatives When “all of the above” is used as an answer, test-takers who can identify more than one alternative as correct can select the correct answer even if unsure about other alternative(s).

In the example below, the script can't create the folder if the user enters illegal characters for folder names.

The best practice is to anticipate what type of file path we expect the user to pass.

We can then validate that before executing any code that could possibly make unexpected changes to the system.
