Who is accountable for maximizing the value of the product and managing the Product Backlog?

• The Scrum Master — they facilitate all ceremonies and make final prioritization decisions
• The Product Owner — they prioritize the backlog and represent the voice of the customer and business
• The Development Team Lead — they decide which features are built first
• The Stakeholders — they vote on which backlog items are most important

A developer tells the Scrum Master: "I've been waiting three days for access to the test database." What is the Scrum Master's primary responsibility in response to this?

• Tell the developer to create a Jira ticket and wait for IT to resolve it — this applies when inputs are pre-validated at the API gateway, not in this context
• Inform the Product Owner so they can de-prioritize the affected stories
• Treat this as an impediment and actively work to remove it so the developer can continue
• Add extra time to the sprint to compensate for the delay

A company hires a QA engineer for their Scrum team. According to Scrum, which role does this person belong to?

• Quality Gate — a specialized role that exists alongside the three standard Scrum roles
• Scrum Master — the QA engineer should facilitate the testing ceremonies
• An external reviewer — QA works independently of the core Scrum team
• Developers — QA is part of the Development team; quality is a shared, collective responsibility
