Which one of the following functions would be responsible for the management of a data centre?

Technical management manages technical skills and resources for infrastructure support, not the physical facility itself.

The service desk is a function focused on handling user communications such as incidents and service requests, not physical environments.

Application management is responsible for managing applications throughout their lifecycle, not physical data centre facilities.

Facilities management is one of the four ITIL functions and is specifically responsible for managing the physical environment in which IT infrastructure is housed, including data centres, power, cooling, and physical access controls. It ensures the physical conditions meet the requirements for running IT services reliably and securely.
