A.7.11 Supporting utilities
Information processing facilities are to be protected against power cuts and other disruption caused by failures of supporting utilities. Purpose (stated in ISO/IEC 27002:2022): prevents loss, compromise or interruption of operations caused by failure of supporting utilities. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 7.11.

Clauses 4 to 10 are the management-system requirements: none of them can be excluded when an organisation claims conformity. The 93 Annex A controls are a reference set: one may be excluded with a justification in the Statement of Applicability. Certification bodies assess conformity; the evidence lists here are what auditors commonly ask for, not a list the standard prescribes.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Generators and UPS are not load-tested regularly
- Building management systems sit on the corporate network or are reachable from the internet
- A single power or telecom feed is a single point of failure
- Cooling capacity was not reviewed after adding equipment
