Posture Policy Conditions per AD Group in Cisco ISE
An engineer is configuring a posture policy for Windows 10 endpoints and wants to ensure that users in each AD group have different conditions to meet to be compliant. What must be done to accomplish this task?
Community Insight
The question tests ISE posture policy condition types, and the trap is confusing posture "service conditions" (Windows/macOS service checks) with "simple conditions" that can evaluate AD group membership.
In Cisco ISE, a posture policy's Other Conditions can reference a Simple Condition that matches AD group membership, letting each Windows 10 AD group meet a different set of compliance requirements. This page establishes why option C is the correct configuration and why service conditions are the wrong tool.
The most common wrong answer is B: "service conditions" sound like a policy-scoping mechanism, but in ISE Posture a Service Condition checks whether a Windows service or macOS daemon is running — it cannot map an AD group to a posture requirement.

Why the Answer Is Correct
In Cisco ISE a posture policy is built from posture requirements plus optional Other Conditions, and the Other Conditions can reference Simple Conditions from the Simple dictionary. Those Simple Conditions can test identity/AD group membership, so creating one Simple Condition per AD group and calling it in the posture policy is exactly what lets each Windows 10 AD group face different compliance checks. This is option C. As Cachaman wrote after lab testing, "You can MAP AD groups to simple conditions", and NikoTomas stated flatly that "Correct is C". Cname explained the key distinction: a Simple Condition "can reference AD group membership and be used under Other Conditions in a Posture Policy." That is the supported ISE design for per-group posture differentiation.Why the Other Options Are Wrong
Option A treats AD groups as something you put into posture requirements, but posture requirements are the checks themselves (antivirus running, file exists, registry value, etc.) and their remediation actions; they do not select users by AD group. Option B says "create service conditions to map each one", which is the trap: ISE Service Conditions are posture checks for whether a Windows service or macOS daemon is running, not a way to bind an AD group to a posture requirement. Option D moves the grouping into the authorization policy, but authorization policies evaluate posture status and assign authorization profiles; they do not define which posture conditions a given AD group must satisfy. The group-to-condition mapping belongs in the posture policy's Other Conditions, so C remains the only workable answer.Community Comment Notes
The thread is split, but the reasoning favors C. Cachaman reported lab proof, and NikoTomas declared C correct while dismissing A and B. Cname gave the cleanest technical distinction: Simple Conditions handle AD group membership, while Service Conditions only check whether a service is running. The B voters (YmerG, madcloud, NullNull88, and XBfoundX) seem to latch onto madcloud's phrase "create service conditions" under posture policy, which misuses the term service condition. denverfly's D choice also misplaces the logic, because the authorization policy consumes posture results rather than producing per-AD-group posture conditions.Exam Strategy
Memorize the ISE condition dictionaries: Simple Conditions can test AD group membership, while Service Conditions test service/daemon state. On exam questions about per-group posture differences, look for a Simple Condition referenced in the posture policy's Other Conditions, not a service condition or an authorization rule.
Frequently Asked Questions
Why is option B's service condition wrong for mapping AD groups to posture requirements?
A Service Condition in ISE checks whether a Windows service or macOS daemon is running; it does not evaluate AD group membership, so it cannot differentiate posture per AD group.
Where in the posture policy does the AD group Simple Condition get applied?
It is referenced under the posture policy's Other Conditions; the policy then applies its posture requirements only to endpoints whose users match that AD group condition.
