A user is allowed to access the file labeled "Financial Forecast," but only between 9:00 a.m. and 5:00 p.m., Monday through Friday. Which type of access mechanism should be used to accomplish this?
There is (CISSP All-In-One Exam Guide):
• Non-RBAC Users are mapped directly to applications and no roles are used.
• Limited RBAC Users are mapped to multiple roles and mapped directly to other types of applications that do not have role-based access functionality.
• Hybrid RBAC Users are mapped to multiapplication roles with only selected rights assigned to those roles.
• Full RBAC Users are mapped to enterprise roles.

But I don't think it is the answer for this question.
D. Rule-based access control
Rule-based access control allows you to define specific rules or conditions that determine when and under what circumstances a user is granted access to a resource. In this case, the rule would be based on time and day restrictions (e.g., 9:00 a.m. to 5:00 p.m., Monday through Friday) for accessing the file "Financial Forecast." Rule-based access control provides the flexibility to enforce access policies based on various conditions or criteria.
D. Rule-based access control
Rule-based access control (RBAC) uses specific rules that dictate who can access a resource and under what circumstances. In the scenario described, the access to the "Financial Forecast" file is contingent upon a specific time frame (9:00 a.m. to 5:00 p.m.) and specific days (Monday through Friday). This type of conditional access is best managed using rule-based access control.
Given answer of Limited Role-BAC is correct. As this applies to a specific user (i.e. is NOT applying global rules to all subjects... Remember that CISSP definition of Rule-Based Access Control is applying global rules to all subjects).
Source: CISSP Study guide 9th ed. page 682.
Don't think it is Rule-based, because a rule is global to all subjects here, like a firewall rule. If this one is true, then this rule applies to all users and not just this user.
I didn't know limited RBAC existed, untill I saw this https://books.google.nl/books?id=9gCn86CmsNQC&pg=PA121&lpg=PA121&dq=limited+RBAC&source=bl&ots=rjGtYpQR5H&sig=ACfU3U29lpqfWMCAjMhgP_G4KX4UIgpc-w&hl=nl&sa=X&ved=2ahUKEwio4uSw49b_AhWrNOwKHUrkCGAQ6AF6BAgkEAM#v=onepage&q=limited%20RBAC&f=false
So out of the four answers I would choose B
limited role-based access control allows user access and assigns roles via authorized apps and assigned role within the app. There in the diagram, you see Bob, our subject, accessing applications one, two or three, and given his access to application one, by doing that, he is therefore assigned role A within application one. https://cloudacademy.com/course/cissp-domain-5-module-3/implementing-and-managing-authorization-mechanisms/

Looks like B
Answer is B. a rule-based access control setting, an administrator might set access hours for the regular business day. In this instance, a person cannot gain entry into your building outside the hours of 9 a.m – 5 p.m
I meant the answer is C. a rule-based access control setting, an administrator might set access hours for the regular business day. In this instance, a person cannot gain entry into your building outside the hours of 9 a.m – 5 p.m
