Which of the following are included within Release and Deployment Models? (1) Roles and responsibilities (2) Template release and deployment (3) Supporting systems, tools and procedures. (4) Handover

Excluding handover activities and responsibilities (item 4) is incorrect because defining how services transfer to operational teams is a core component of Release and Deployment Models.

Excluding roles and responsibilities (item 1) is incorrect because defining who is accountable for each release and deployment activity is fundamental to the model.

Release and Deployment Models in ITIL encompass roles and responsibilities, template release and deployment plans, supporting systems and tools, and handover activities and responsibilities. These components together provide a standardized framework that reduces risk, improves repeatability, and ensures a smooth transition of released services into operations.

This option omits both template release plans (item 2) and supporting tools and procedures (item 3), which are essential structural components of Release and Deployment Models.
