The correct answer is B. system configuration.
In Cisco UCS Manager, backup types are separated by what part of the domain they capture. The system configuration backup contains the UCS system-level settings, which include administrative and infrastructure-related items such as AAA configuration, authentication settings, user accounts, RBAC roles, time settings, communication services, and other management-plane parameters. This directly matches the requirement to back up AAA and RBAC.
The question also requires the file to be in a human-readable format. Cisco UCS uses an XML-based format for configuration backups such as system configuration, logical configuration, and all configuration, making them readable and reviewable. By contrast, full state backup is intended for disaster recovery and is a binary image, so it is not human-readable.
Option C (logical configuration) is incorrect because it focuses on logical objects such as service profiles, pools, policies, and templates, not primarily AAA/RBAC. Option D (all configuration) would include AAA and RBAC, but it is broader than required. Since the question specifically asks for the backup type that contains AAA and RBAC, the most precise and correct choice is system configuration.
