An effective Service Desk Analyst contributes actively to team performance rather than working as an isolated technical resource. Statements 1, 2, and 3 correctly describe this responsibility. First, analysts should collaborate openly and effectively. Service Desk work depends on information sharing, coordinated resolution, escalation, and cooperation with colleagues and specialist teams. Second, analysts should help create a safe and supportive workplace where colleagues can ask questions, raise concerns, learn from errors, and contribute ideas without unnecessary fear. Third, analysts can support colleagues during onboarding through buddying and skill development, accelerating integration into the team and transferring practical knowledge. Statement 4, ''retaining knowledge and information,'' is inconsistent with effective team behaviour if it means keeping useful information to oneself. Modern service management depends on knowledge sharing, documentation, and collaborative learning. Useful knowledge should be captured and made available to colleagues where appropriate. The SDA v9 specification develops collaboration with colleagues, rapport, communication skills, and professional Service Desk behaviour. Therefore, 1, 2, and 3 form the correct combination.
