Which of the following are Service Desk organizational structures? (1) Local Service Desk (2) Virtual Service Desk (3) IT Help Desk (4) Follow the Sun

This option includes 'IT Help Desk' (3), which is not a recognized ITIL organizational structure, and incorrectly excludes Local Service Desk (1), which is a valid model.

ITIL Service Operation identifies Local Service Desk (physically co-located near users), Virtual Service Desk (geographically dispersed staff unified through technology to appear as a single contact point), and Follow the Sun (globally distributed desks that hand off coverage across time zones for 24-hour support) as the three official organizational structures. 'IT Help Desk' is a colloquial term, not a defined ITIL Service Desk organizational model.

This option includes 'IT Help Desk' (3), which has no standing as a defined ITIL Service Desk structure, making this combination incorrect.

This option includes 'IT Help Desk' (3), which is not an ITIL-defined structure, and excludes Virtual Service Desk (2), which is a formally recognized ITIL organizational model.
