Which of the following activities are helped by recording relationships between Configuration Items (CIs)? (1) Assessing the impact and cause of Incidents and Problems (2) Assessing the impact of prop

Excluding activities 3 and 4 is incorrect because planning a service change and planning a technology refresh both require knowing which CIs are linked so that scope and risk can be accurately determined.

CI relationships document how components depend on and affect each other, which is essential for tracing incident root causes (activity 1), modeling change blast radius (activity 2), designing changes to connected components (activity 3), and identifying what must be replaced or retested during a technology refresh (activity 4). Because all four activities require dependency awareness, all four are supported.

Excluding activity 3 is incorrect because designing a change to an existing service directly depends on understanding CI relationships to avoid unintended impacts on connected components.

Excluding activity 2 is incorrect because assessing the impact of proposed changes is one of the primary purposes of maintaining CI relationship data in the CMDB.
