This 220-1202 practice question tests your understanding of scripting basics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is tasked with creating a PowerShell script that will parse a CSV file containing user information and create local user accounts on a Windows 10 machine. The CSV has columns: 'Username', 'FullName', 'Password'. The script must skip any row where the 'Username' is empty. Which control structure should the technician use to handle this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
An 'if' statement to test whether the Username property is not empty
Option C is correct because the requirement is to conditionally skip rows based on a property value. An 'if' statement in PowerShell allows you to test whether the 'Username' property is empty or null using a condition like `if ($_.Username -ne '')` and then skip the row with `continue` or simply not process it. This is the most direct and efficient control structure for a simple boolean check on each row.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
A 'for' loop with a counter to skip empty rows
Why it's wrong here
A for loop can iterate but does not inherently check for empty values without additional logic.
✗
A 'switch' statement to match usernames
Why it's wrong here
Switch is used for matching multiple conditions, not for skipping empty values.
✓
An 'if' statement to test whether the Username property is not empty
Why this is correct
An if statement can check the condition and skip processing if the username is empty.

✗
A 'try/catch' block to handle errors when creating the account
Why it's wrong here
Try/catch handles runtime errors but does not prevent processing empty usernames.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between control structures used for conditional logic versus iteration or error handling, and the trap here is that candidates may overcomplicate the solution by choosing a loop or switch when a simple conditional check is the most appropriate and efficient choice.
Detailed technical explanation
How to think about this question
In PowerShell, when parsing a CSV with `Import-Csv`, each row becomes a custom object with properties matching the column headers. The `if` statement can directly evaluate the property using `-eq ''` or `[string]::IsNullOrWhiteSpace()` to handle both empty strings and whitespace. This approach is more efficient than looping constructs because it avoids unnecessary iterations and keeps the script readable, which is critical in production scripts where performance and maintainability matter.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
