CAS-004 Practice Question: Merging with another organization and needs to…
A company is merging with another organization and needs to integrate their identity management systems. The security team is concerned about maintaining least privilege and segregation of duties across the combined environment. Which of the following approaches BEST addresses these concerns?
⚠ Common exam trap
CompTIA often tests the misconception that SSO or automated provisioning alone solves authorization and segregation issues, when in fact they are authentication and enforcement mechanisms that require proper role design (via role-mining) to achieve least privilege.

Correct answer & explanation
✓
Perform a role-mining exercise and design new roles based on common job functions
Role-mining analyzes existing user entitlements and access patterns across both organizations to identify common job functions, enabling the design of least-privilege roles that enforce segregation of duties. This approach directly addresses the security concerns by ensuring users receive only the permissions necessary for their roles, preventing conflicts of interest inherent in merged environments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy single sign-on (SSO) across both organizations
Why it's wrong here
SSO simplifies access but does not enforce least privilege or segregation.
- ✗
Create a unified user group with the same permissions for all employees
Why it's wrong here
Violates least privilege and segregation of duties.
- ✗
Use an identity governance and administration (IGA) tool with automated provisioning
Why it's wrong here
IGA tools support governance but require role design first to be effective.
- ✓
Perform a role-mining exercise and design new roles based on common job functions
Why this is correct
Role mining ensures roles are aligned with business needs and reduces conflict.
