Scripting and Toolmaking with PowerShell (M55627A) — Lesson 2: Advanced Functions and Pipeline Toolmaking

Learning Objectives

• Create advanced functions with CmdletBinding and parameter attributes
• Support pipeline input, validation, common parameters, and ShouldProcess
• Return predictable objects and design composable commands

Detailed Topics

• Create advanced functions with CmdletBinding and parameter attributes: Create advanced functions with CmdletBinding and parameter attributes
• Support pipeline input: Support pipeline input, validation, common parameters, and ShouldProcess
• Return predictable objects and design composable commands: Return predictable objects and design composable commands

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected outcome.
2. Demonstrate the relevant configuration, analysis, code, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, or test evidence.
4. Compare the observed result with the stated acceptance criteria.

Hands-On Activity

Create a pipeline-friendly advanced function with safe change controls.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, permissions, data, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, support ownership, and user or business impact.

Validation Checklist

• The requirement and expected outcome are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Advanced Functions and Pipeline Toolmaking in a realistic scenario and validate the result with documented evidence.
