The platform team reduced the time it takes a new hire to open their first meaningful code change to just one day. Which phrase is correct?
'Time-to-first-PR' is the standard metric for developer onboarding speed — how quickly a new developer can open their first pull request. It measures platform efficiency and onboarding quality.

The platform has a tool that generates all the files, configuration, and boilerplate for a new microservice in 10 minutes. What is this tool called?
A 'scaffolder' (or scaffolding tool) generates the initial structure of a new service — files, config, CI pipelines, README — from templates. Backstage's Software Templates use this term.

New hires use a web interface to browse documentation, run self-service workflows, and discover internal services without asking colleagues. What is this interface called?
A 'developer portal' (like Backstage) is the self-service web interface that centralizes documentation, service catalog, onboarding guides, and tooling — replacing tribal knowledge with structured discovery.

The platform provides a pre-approved, automated path for building and deploying services that removes 40 manual configuration steps. What is this called?
The 'golden path' is the opinionated, platform-approved way to build and deploy software. It encodes best practices into automation, dramatically reducing the manual steps required from developers.

A new engineer joined on Monday. By Tuesday afternoon, they deployed their first change to a non-production environment using the platform's self-service tools. What does this demonstrate?
'Rapid time-to-first-deployment' shows the platform enables new developers to go from joining to shipping quickly. Reducing this metric is a key goal of internal developer platforms.

Sarah, a new onboarding specialist, is explaining the automated deployment process to David. Which of the following phrases best describes the concept? 'We're leveraging a continuous integration pipeline with automated testing and staging environments.'
This scenario tests understanding of continuous integration and delivery pipelines. The phrase describes a common practice where changes are automatically built, tested, and deployed to staging environments before going live. The other options represent related but distinct concepts – blue-green deployments, IaC, or simply manual steps.

During a Slack conversation with the team, Mark asks: 'How do I quickly get feedback on my code before submitting a pull request?' Liam responds: 'You can use the platform's code review tools to initiate inline reviews.' What does 'inline review' specifically refer to?
The term 'inline review' in this context relates directly to how modern platforms facilitate collaborative code reviews. It signifies a focused, immediate feedback loop attached to the specific code change being reviewed, often using features like commenting and annotations directly within the version control system. The other options represent different types of reviews.

The platform's API returns the following JSON response after a new user signs up: {
{"status": "success", "user_id": "12345", "email": "john.doe@example.com"}
What does this response primarily indicate?
This question tests understanding of API response formats and their meaning. The JSON response confirms that the user account was created successfully and provides key identifiers (user ID and email) for future interactions. The 'status' field further reinforces this success.

During a standup meeting, Emily reports: 'I've been working on integrating the new payment gateway. I've completed the initial setup and am now focusing on implementing the transaction processing logic.' What is Emily primarily describing?
This scenario focuses on accurately describing work progress. Emily's statement outlines the specific steps she's undertaking within her assigned development task – detailing the stages of integration and implementation. Understanding this phrasing is crucial for clear communication during standups.

You are reviewing a pull request description submitted by a new developer. It reads: 'This PR implements the user authentication flow using OAuth 2.0 and includes unit tests.' What does this description primarily communicate?
A good PR description should provide a concise overview of the changes. This example accurately summarizes the key aspects of the pull request – namely, the authentication flow implementation using OAuth 2.0 and the inclusion of unit tests. It's about conveying the core functionality.
What will I practice in "Developer Onboarding on Platforms"?
This is a Platform Engineering exercise set. It walks through 10 scenario-based multiple-choice questions built around real usage of platform engineering terminology that IT professionals encounter on the job.
Is this exercise free to use?
Yes. Every exercise on CoderSlingo, including this one, is free to complete with no account, sign-up, or paywall.
How many questions are in this exercise?
This set contains 10 questions. Each one shows immediate feedback and a detailed explanation after you answer, so you learn the correct usage right away rather than waiting for a final score.
Do I need prior experience to complete this exercise?
No prior experience is required. Each question includes a full explanation covering the reasoning behind the correct answer, so the exercise itself teaches the platform engineering vocabulary as you go.
Can I retry the exercise if I get questions wrong?
Yes — use the "Try again" button on the results screen to reset your answers and go through all the questions again. There is no limit on attempts.
Is my progress saved?
Your answers and score for the current session are tracked in the browser as you go. No account or login is needed, and there is nothing to install.
What if I don't understand a term used in a question?
Read the explanation shown after you answer each question — it breaks down the correct term in plain English with a real-world example. You can also check the site Glossary for quick definitions.
How is this different from reading a blog article on the topic?
Exercises like this one are interactive drills that test and reinforce specific vocabulary through multiple-choice questions, while blog articles explain concepts in prose. Practising here after reading builds active recall, not just passive recognition.
