The answer is to perform a role-mining exercise and design new roles based on common job functions. This is correct because role-mining systematically analyzes existing user entitlements and access patterns across both organizations, identifying overlapping job functions and redundant permissions, which allows security teams to build least-privilege roles that inherently enforce segregation of duties. On the CompTIA SecurityX CAS-004 exam, this scenario tests your understanding of merger identity management and how role-mining directly addresses the risk of privilege creep and SoD violations when combining disparate IAM systems. A common trap is to choose a simple user migration or manual permission mapping, but those ignore the need to discover hidden commonalities. Memory tip: think of role-mining as “data-driven role design”—you mine the access data first, then build roles, never the reverse.
CAS-004 Governance, Risk and Compliance Practice Question
This CAS-004 practice question tests your understanding of governance, risk and compliance. 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 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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Perform a role-mining exercise and design new roles based on common job functions
Option D is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
Role-mining uses algorithms (e.g., role-based access control (RBAC) role engineering) to analyze entitlement data from directories, applications, and databases, applying techniques like hierarchical clustering or attribute-based grouping to identify candidate roles. In a merger, this process must reconcile disparate identity stores (e.g., Active Directory and LDAP) and account for differing naming conventions, requiring careful mapping of job functions across the combined workforce to avoid role explosion or overly coarse roles that undermine segregation of duties.

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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
