Which statement about services is CORRECT?

Services provided to business units within the same organization are classified as internal services from the IT provider's perspective, not external services.

ITIL distinguishes services by the relationship between provider and consumer. Internal services include those delivered to the IT department by suppliers - these are underpinning services that support internal IT operations rather than being delivered directly to end customers or business units. This reflects the ITIL concept of underpinning contracts where external suppliers provide services that the IT organization consumes internally.

In ITIL terminology, external services are defined by the provider being external, not solely by the customer being external - conflating the recipient with the classification misrepresents the framework's definition.

Internal services are delivered to internal stakeholders such as business units or IT departments within the same organization, not to external customers.
