TOGAF defines levels of architecture conformance. Which of the following describes a situation where some features in an architecture specification have not been implemented, but those that have are in accordance with the specification?

The description of a situation where some features in an architecture specification have not been implemented, but those that have are in accordance with the specification aligns with the term "compliant." In the context of TOGAF, being compliant indicates that the portions of the architecture that have been implemented adhere to the established guidelines and specifications, even if not everything has been fully executed.

This term emphasizes that compliance can be partial; systems can still function within the intended framework as long as the implemented elements align with the architectural standards. It demonstrates that the organization is making progress towards achieving full conformance while already adhering to the necessary rules for the implemented features.

In contrast, terms like "conformant" would typically imply complete adherence to the specification without deviations or omissions, making it an unsuitable descriptor for this situation. "Consistent" relates to the internal alignment of components rather than compliance with standards, while "non-conformant" clearly indicates a failure to meet the criteria altogether, which does not apply here.
