In Huawei campus authentication architecture, anauthentication profiledefines how users are authenticated and which domain is used during authentication. A key concept is theforcible domain, which has the highest priority during domain selection. If a forcible domain is configured, the device ignores any domain information carried in the user name and forcibly authenticates the user in the specified domain. Therefore, statementD is correct.
Statement A is incorrect because the default domaincan be modifiedusing CLI commands, allowing administrators to flexibly control user authentication behavior. Statement B is also incorrect; on the same interface, different authentication types (such as 802.1X, MAC authentication, and Portal)can be configured with different domains, depending on access control requirements.
Statement C is incorrect because the default authentication triggering sequence on Huawei devices is802.1X → MAC address authentication → Portal authentication, not the order described. This sequence ensures strong authentication is attempted first before falling back to weaker mechanisms.
According to HCIP Datacom Campus Network documentation, forcible domain configuration guarantees unified policy enforcement and simplifies authentication control, making option D the only correct statement.
