COURSE OVERVIEW

What you will learn

What you will make

Build a paginated Graph-style report that detects loops and keeps a failed collection separate from a complete empty result.

What you need

PowerShell objects; tenant access required only for optional live extension.

Use PowerShell 7. This script simulates two Graph-shaped pages. It deliberately does not import the Graph module or call Microsoft services.

How to work through it

  • Understand the mechanism and predict the result.
  • Run or trace the fixture and preserve the evidence.
  • Change the inputs, expose a failure and explain the repair.
  • Complete a project and answer the retrieval questions.

Scope

A focused practical workshop, not a complete beginner-to-expert programme. Allow time for the exercises and project; the pace depends on your prior experience. Related CogniSkill books are optional next steps. No purchase is required.

Applied capability and learning route

Design complete, least-privilege directory reporting with pagination and retry controls.

Follow the lessons in order: establish the model, trace the supplied evidence, attempt the case, compare the worked solution, and complete the changed-condition project. The target is intermediate reasoning within this stated scope, not mastery of the entire profession or product. If a prerequisite is unfamiliar, pause and use the linked foundational teaching before attempting the project.

All teaching, explained answers and core synthetic practice are free. Some operational labs require separately available software, a licensed test tenant or an authorized lab; offline completion does not claim hands-on product proficiency.

How to complete this course

Study the worked examples, attempt the exercises before opening solutions, and submit your own project notes. Completion records are self-reported; practical competence requires the stated verification.

What you will learn

  • Separate local transformation from API access
  • Choose minimum documented read permissions
  • Plan paging, failure handling and disconnection
  • Design complete, least-privilege directory reporting with pagination and retry controls.

Before you start

  • PowerShell objects; tenant access required only for optional live extension.

Practice environment

  • Use the lesson’s fictional data or local lab. Cloud configuration is not required for the core tabletop exercises; follow the stated software prerequisites for executable labs.

Tested versions

  • See worked example verification notes; optional tenant features require current provider checks.

Technical reference

Practical project

Add page count and completeness metadata to the fixture collector. Test an empty successful result, two pages, a missing second page and a repeated next-link. Write a separate live-integration plan naming endpoint, permission model, retry limit and export fields; do not add real credentials.
Applied transfer project: Implement a mock page-fetch function and test normal pagination, a repeated next link, retry exhaustion and a duplicated user across pages. Decide whether the report needs unique identities or raw records and document your deduplication key. Add a permission review showing the exact read operation and the least-privilege documented authorization for the chosen mode. Keep secrets and raw tokens out of logs.

Check your project

  • Local and live steps distinguished
  • Permissions justified
  • Pagination checked
  • No tokens retained
  • Applied laboratory rubric: five dimensions, 0–2 each; target 8/10 with no zero in main result or safety. Native quiz score is separate.

Use these criteria for self-review. Completing a lesson records your progress; it does not verify code correctness.
