In the Team Topologies model, what is a 'stream-aligned team'?
Stream-aligned teams are the primary team type in Team Topologies — they deliver value directly. They own a slice of the product end-to-end and interact with platform, enabling, and complicated-subsystem teams to reduce cognitive load and stay focused on their domain.
2 / 14
What is the purpose of a 'platform team' in the Team Topologies model?
The platform team's product is the internal platform — a curated set of services, APIs, and tooling that stream-aligned teams consume without needing to understand the underlying complexity. The platform team measures success by adoption and developer satisfaction, not just availability.
3 / 14
What does 'cognitive load reduction' mean as a platform team goal?
Cognitive load reduction is a central Theme Topologies concept. Every operational concern a platform team absorbs (CI setup, security scanning, log aggregation) is cognitive load removed from stream-aligned teams, letting them focus on business logic. The platform team exists to shrink the surface area of things product teams must understand.

What is the 'golden path' (or 'paved road') in platform engineering vocabulary?
The golden path (Netflix term) or paved road means: if you follow our recommended toolchain and templates, everything just works. It trades flexibility for speed and consistency. Teams can go off-path, but they lose platform support. The goal is to make the right way the easy way.

What does 'you build it you run it' mean in a platform team context?
'You build it you run it' (Werner Vogels, Amazon) is a DevOps principle: product teams own their services end-to-end including production. Platform teams enable this by providing the operational tooling (observability, deployment automation) so teams can run their own services without needing a dedicated ops handoff.

During a code review for this PR, Sarah (a member of the Platform Team) comments to David: 'This error response format is fantastic! It's exactly what we need – predictable and easy for developers to integrate. It really helps us offload some of the burden of handling errors from our consuming teams.'
Considering Sarah's comment, which of the following best explains the Platform Team's role in this refactoring effort?
The key here is understanding that Platform Teams are focused on *reducing cognitive load* for their consuming teams. Sarah's comment directly reflects this goal: by providing a consistent and predictable API with standardized error responses, the Platform Team allows developers to focus on building applications rather than wrestling with complex or undocumented error handling logic. Options A, B, and C misrepresent the core function of a platform team—they are about enablement, not purely technical optimization, security compliance, or reactive infrastructure management.

During a standup meeting, Mark (from the Platform Team) says: 'We're focusing on reducing cognitive load for our consumers by standardizing the API response format across all microservices. This means creating reusable components and clear documentation to minimize the effort developers spend understanding and integrating with new services.' Which of the following best describes Mark's statement in the context of Team Topologies?
Mark's statement directly relates to 'cognitive load reduction', a key goal of platform teams. The core purpose is to simplify the experience for developers consuming the platform's services – reducing their mental effort through standardization and clear documentation. Option A describes a different technical focus, while B and C are not relevant to the Team Topologies model.

As a Platform Team lead, you're drafting an API response description for a new service. You want to ensure it aligns with the 'golden path' principle. Which of the following approaches would be MOST effective?
The 'golden path' emphasizes simplicity and stability. A minimal, well-defined API with strong versioning allows downstream teams to integrate quickly without being blocked by rapidly evolving changes or complex features. Options A, B and C introduce unnecessary complexity that contradicts the core principle of a streamlined delivery path.

In a Slack channel discussing a new feature request from a client team, Alex (a Platform Team member) responds: 'To ensure we're aligning with the stream-aligned teams, let's create a dedicated platform service that handles authentication and authorization for this specific use case. This will allow them to focus on their core business logic without worrying about security concerns.' What is Alex primarily advocating for?
Alex is proposing a platform service designed to reduce the cognitive load and operational burden on the client team. By abstracting away authentication and authorization – often complex tasks – into a reusable component, Alex's approach aligns with the 'stream-aligned team' concept: empowering teams to focus on their core business value.

During a code review of a new API endpoint, Emily (from the Platform Team) notes: 'This response format is fantastic! It's exactly what we need – predictable and easy for developers to integrate. It reduces the risk of integration errors by providing consistent data structures.' What aspect of platform engineering does this comment primarily highlight?
Emily's comment directly addresses the concept of 'creating reusable components.' A predictable and consistent response format minimizes integration issues – a core benefit of platform teams providing standardized building blocks. Reducing integration risk is a key outcome of this approach.

A developer submits a pull request with a complex logging system for a new service. During the review, David (from the Platform Team) asks: 'Can we decouple this logging functionality into a separate platform service? This would allow us to manage logging centrally and reduce duplication across services.' What is David's intention?
David is advocating for code reuse – a foundational principle of platform engineering. By extracting the logging functionality into a dedicated service, he aims to avoid duplication and reduce technical debt, aligning with the Platform Team's goal of providing reusable components.
