- A
List the user's group memberships and examine the policies attached to those groups and any roles the user can assume.
This helps in understanding the inherited permissions.
- B
Review the user's recent access logs to see which actions were allowed.
Why wrong: Access logs show historical actions, not all effective permissions.
- C
Check the resource-based policies on each resource the user might access.
Why wrong: Resource-based policies control access from a resource perspective, not the user's effective permissions.
- D
Use a 'simulate principal policy' API call to evaluate the user's effective permissions.
This API evaluates all policies attached to the user, groups, and roles to determine effective permissions.
- E
Log in as the root user and run a permissions report.
Why wrong: The root user has full access and cannot be used to simulate another user's permissions.
Quick Answer
The answer is to use a 'simulate principal policy' API call and to list the user's group memberships and assumable roles. These two methods are correct because effective IAM permissions are the sum of all policies applied directly to the user, plus those inherited from any groups the user belongs to and any roles the user can assume. The simulate principal policy API evaluates the full set of permissions across all these sources, while listing groups and roles reveals the inheritance chain that may grant unexpected access. On the CompTIA Cloud+ CV0-004 exam, this question tests your understanding that permissions are rarely static—they flow from multiple attachments, making it easy to miss inherited rights. A common trap is focusing only on user-attached policies, ignoring group or role-based inheritance. Memory tip: think "Simulate + List" to uncover the full permission picture—like tracing a river to its tributaries.
CV0-004 Security Practice Question
This CV0-004 practice question tests your understanding of security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A cloud administrator notices that an IAM user has permissions that are not explicitly assigned. The administrator suspects that the user is inheriting permissions through group membership or role assignment. Which TWO methods can the administrator use to identify all effective permissions for this user? (Choose TWO.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
List the user's group memberships and examine the policies attached to those groups and any roles the user can assume.
Option A is correct because group memberships and assumable roles are common sources of inherited permissions. By listing the user's groups and examining the policies attached to those groups, as well as any roles the user can assume, the administrator can trace the origin of the unexpected permissions. This method directly identifies the inheritance chain that grants permissions not explicitly assigned to the user.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between inherited permissions (from groups/roles) and explicit permissions, and the trap here is that candidates may confuse reviewing access logs (which show past actions) with evaluating effective permissions (which shows potential actions).
Trap categories for this question
Command / output trap
Access logs show historical actions, not all effective permissions.
Detailed technical explanation
How to think about this question
Effective permissions in AWS IAM are the result of evaluating all identity-based policies (user, group, and role policies) and resource-based policies, with an explicit deny overriding any allow. The 'simulate principal policy' API (AWS IAM Policy Simulator) evaluates the combined effect of all applicable policies for a given principal, resource, and action, providing a comprehensive view of what the user can actually do. This is critical in complex environments where users belong to multiple groups or assume roles with overlapping permissions.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
