SC-900 Practice Question: Describe the concepts of security, compliance, and identity

This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. 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 assigns permissions to users based strictly on their job title (e.g., Sales Manager can edit documents, Sales User can only read). Which identity and access management concept is being implemented?

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

Role-Based Access Control (RBAC)

Role-Based Access Control (RBAC) is the correct concept because it assigns permissions to users based on their job title or role within the organization. In this scenario, the Sales Manager role is granted edit permissions, while the Sales User role is restricted to read-only, which is a direct implementation of RBAC where access rights are tied to roles rather than individual users.

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.

  • Least privilege

    Why it's wrong here

    Least privilege is a security principle that grants users the minimum level of access needed to perform their job. While RBAC often helps achieve least privilege, the scenario specifically describes assigning permissions by job role, which is RBAC.

    When this WOULD be correct

    A question stating: 'A company ensures users have only the permissions necessary to perform their specific tasks, nothing more. Which concept is this?' would make least privilege the correct answer.

  • Role-Based Access Control (RBAC)

    Why this is correct

    RBAC assigns permissions to users based on their defined roles or job functions. This matches the scenario where permissions are determined by job title.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Defense in depth

    Why it's wrong here

    Defense in depth is a security strategy that uses multiple layers of controls. It does not refer to role-based permission assignment.

  • Zero Trust

    Why it's wrong here

    Zero Trust is a security model that assumes no implicit trust and verifies every access request. It is broader than role-based assignment.

    When this WOULD be correct

    A question asks: 'A company implements a security model where no user or device is trusted by default, and every access request is verified regardless of location. Which concept is this?' Zero Trust would be the correct answer.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SC-900 exam frequently reuses these exact scenarios with slightly different constraints.

Role-Based Access Control (RBAC)Correct answer

Why this is correct

RBAC assigns permissions to users based on their defined roles or job functions. This matches the scenario where permissions are determined by job title.

Least privilegeWrong answer — click to see why

Why this is wrong here

Least privilege grants users only the minimum permissions needed to perform their job, not based on job title. The question describes permissions assigned by job title, which is RBAC, not least privilege.

★ When this WOULD be the correct answer

A question stating: 'A company ensures users have only the permissions necessary to perform their specific tasks, nothing more. Which concept is this?' would make least privilege the correct answer.

Why candidates choose this

Candidates may confuse least privilege with RBAC because both involve limiting permissions, but they focus on different aspects: RBAC assigns by role, while least privilege minimizes permissions regardless of role.

Zero TrustWrong answer — click to see why

Why this is wrong here

Zero Trust is a security model that assumes no implicit trust and requires continuous verification, not a method for assigning permissions based on job titles. The question describes role-based permission assignment, which is RBAC.

★ When this WOULD be the correct answer

A question asks: 'A company implements a security model where no user or device is trusted by default, and every access request is verified regardless of location. Which concept is this?' Zero Trust would be the correct answer.

Why candidates choose this

Candidates may confuse Zero Trust with access control because it involves verifying permissions, but Zero Trust is a broader security framework, not a specific access control model like RBAC.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse least privilege with RBAC, thinking that assigning minimal permissions per role is the same as the principle of least privilege, but RBAC is specifically about organizing permissions by role, while least privilege is a broader security goal that can be achieved through RBAC or other methods.

Trap categories for this question

  • Scenario analysis trap

    Least privilege is a security principle that grants users the minimum level of access needed to perform their job. While RBAC often helps achieve least privilege, the scenario specifically describes assigning permissions by job role, which is RBAC.

Detailed technical explanation

How to think about this question

RBAC is defined by the NIST standard (INCITS 359) and uses role hierarchies and permissions that are assigned to roles, not users directly. Under the hood, when a user authenticates, their role membership is resolved via an identity provider (e.g., Azure AD), and access tokens include role claims that are evaluated by the resource (e.g., SharePoint) to enforce permissions. A real-world scenario is in Azure RBAC where a 'Contributor' role can manage resources but not assign permissions, while a 'Reader' role can only view them, mirroring the job-title-based assignment in the question.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
