Which of the following is the correct name for Tier II of the Uptime Institute Data Center Site Infrastructure Tier Standard Topology?

'Concurrently Maintainable Site Infrastructure' is the designation for Tier III, which allows any component to be removed from service without affecting the IT operation.

'Fault-Tolerant Site Infrastructure' is the designation for Tier IV, which provides protection against virtually all physical events and redundant components with multiple independent distribution paths.

'Basic Site Infrastructure' is the designation for Tier I, which includes a single path for power and cooling and no redundancy.

Tier II of the Uptime Institute standard is correctly named 'Redundant Site Infrastructure Capacity Components,' meaning it includes redundant components for power and cooling but typically has a single, non-redundant distribution path, allowing for planned maintenance without affecting operations.
