Exam at a glance

Domain weightings

How much of the exam each domain covers. Spend your study time in proportion — the heavier the domain, the more questions you'll see.

Key terms

GitHub Copilot

GitHub Copilot is an AI pair-programming tool that suggests code and answers questions inside the IDE, CLI, and github.com. GH-300 centers on using it productively, responsibly, and securely.

Copilot Chat

Copilot Chat is the conversational interface to GitHub Copilot for asking questions, explaining code, and generating changes. GH-300 covers its commands, limits, and prompt-file reuse.

Agent Mode

Agent Mode is a GitHub Copilot capability that autonomously plans and carries out multi-step coding tasks across files. GH-300 covers Agent Mode, Copilot Edits, and delegating to sub-agents.

Copilot Edits

Copilot Edits is a GitHub Copilot feature that applies AI-suggested changes across multiple files in a single flow. GH-300 covers it among Copilot's development features.

MCP

MCP (Model Context Protocol) is an open standard that lets AI tools like Copilot connect to external tools and data sources. GH-300 covers using MCP to enhance development workflows.

GitHub Copilot CLI

GitHub Copilot CLI is a command-line interface that brings Copilot assistance to the terminal for generating scripts and managing files. GH-300 covers installing and using it interactively and in sessions.

Prompt engineering

Prompt engineering is the practice of structuring prompts and context to get better output from Copilot. GH-300 dedicates a domain to prompt engineering and context crafting, including zero-shot and few-shot prompting.

Responsible AI

Responsible AI is the practice of using AI ethically and safely, accounting for its risks and limitations. GH-300 requires understanding responsible AI principles and validating Copilot output.

Content exclusion

Content exclusion is a GitHub Copilot setting that prevents specified files or repositories from being used as context. GH-300 covers configuring content exclusions for privacy and safeguards.

Public code filter

The public code filter is a Copilot safeguard that blocks suggestions matching public code, reducing licensing and duplication concerns. GH-300 covers enabling it under privacy and safeguards.

Inline suggestion

An inline suggestion is a code completion that GitHub Copilot proposes directly in the editor as you type. GH-300 covers triggering Copilot through inline suggestions, chat, CLI, and agent mode.

Code suggestion lifecycle

The code suggestion lifecycle is the flow by which Copilot turns editor context into a filtered, post-processed suggestion. GH-300 covers visualizing this lifecycle in the data and architecture domain.

Audit log

An audit log records Copilot-related events for an organization, supporting governance and compliance. GH-300 covers using audit log events when managing organization-wide settings and policies.
