A systems administrator is designing a PowerShell (.ps1) script to parse automated log backups, identify errors, and append summaries to an administrative report. Place the logical scripting steps and constructs in the correct order of execution from top to bottom.
- 1Declare and initialize script environment variables ( ReportFile) to set file system paths.
- 2Initialize a 'foreach' loop construct to iterate through the collection of log files retrieved from $LogPath.
- 3Evaluate an 'if' conditional branch to check if the current log file contains entries matching an 'ERROR' string.
- 4Execute an output redirection command to append matching error lines into $ReportFile.
- 5Terminate the loop construct and output a completion message to the standard console output.

The correct logical order is: 1. Declare and initialize script environment variables ( ReportFile) to set file system paths. 2. Initialize a 'foreach' loop construct to iterate through the collection of log files retrieved from ReportFile. 5. Terminate the loop construct and output a completion message to the standard console output.
In administrative scripting languages (such as PowerShell, Bash, or VBScript), execution flows sequentially from top to bottom. Variable declaration establishes environment configuration before data processing. Iteration constructs ('foreach' loops) cycle through data structures, while conditional constructs ('if' statements) evaluate criteria inside the loop. Actionable output (redirection to report files) occurs upon meeting conditional criteria, and overall script termination occurs after all iterations complete.

Sequential execution and logical flow of basic scripting constructs (variable initialization, loop iteration, conditional branching, and I/O redirection).
