A release manager has decided on a policy of not allowing users to choose to...

TheITIL® 4 Practitioner: Release Managementdocument explains the difference between push and pull approaches in release management:"In a push approach, updates are deployed to users without giving them a choice, often to ensure compliance or security. In a pull approach, users can choose when to adopt updates"(Section 3.2.3).

Option A (A ‘pull’ approach) is incorrect because a pull approach allows users to choose when to accept updates, which contradicts the scenario.

Option B (A ‘push’ approach) is correct, as the policy of not allowing users to choose means the updates are automatically deployed to them, fitting the definition of a push approach.

Option C (Continuous delivery) and Option D (Continuous integration) are development practices, not release deployment strategies. Continuous delivery involves making releases available frequently, but it doesn’t specify whether users must accept them (push) or can choose (pull).

The scenario describes a push approach, making B the correct answer.
