Difficulty: EasyBasic Scripting Languages and Constructs

A technician is writing a simple PowerShell script to automate a routine maintenance task. Place the following script constructs in the correct order to initialize a path variable, evaluate whether the path exists, execute an automated action, and close the execution block.

  1. 1$LogPath = "C:\Logs\system.log"
  2. 2if (Test-Path $LogPath) {
  3. 3Remove-Item -Path $LogPath
  4. 4}

Answer

The proper sequence initializes the target variable (LogPath="C:\Logs\system.log"),openstheconditionalevaluation(if(Test−PathLogPath = "C:\Logs\system.log"), opens the conditional evaluation (if (Test-Path LogPath) {), runs the file deletion command within the block (Remove-Item -Path $LogPath), and closes the control structure (}).
In standard procedural scripting logic, environment variables must be declared and assigned before they can be evaluated by control constructs such as conditional 'if' statements. Once the condition opens, nested tasks run within the block before the enclosing block is terminated.

Step-by-Step Solution

1
Initialize variable
$LogPath variable is set with string value
Scripting constructs require variable assignment prior to evaluation.
2
Open conditional statement
if (Test-Path $LogPath) { is evaluated
Conditional branching checks environmental state before executing reliant actions.
3
Perform action inside block
Remove-Item -Path $LogPath executes
Actions governed by conditional checks reside within the construct body.
4
Terminate block
} closes the block
Closing braces signal the end of the conditional execution scope.
