Quick Answer
The correct answer is built-in roles, custom roles, and service roles. These three categories form the complete taxonomy of Azure RBAC role types, where built-in roles are predefined by Microsoft for common job functions, custom roles allow you to define granular permissions tailored to your organization’s needs, and service roles are specific to Azure resource providers for delegated management. On the AZ-305 exam, this distinction tests your ability to separate Azure RBAC from Entra ID roles—a common trap is confusing directory roles (which govern identity and access in Entra ID) with Azure RBAC role types. Remember that guest roles do not exist as an RBAC category, and directory roles are explicitly for Entra ID, not for controlling Azure resource access. A quick memory tip: think “B-C-S” for Built-in, Custom, and Service—like the three legs of a stool supporting Azure authorization.
This AZ-305 practice question tests your understanding of design identity, governance, and monitoring solutions. 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.
Which THREE are valid Azure RBAC role types? (Choose three.)
Service roles
Service roles are used by Azure services.
Directory roles
Why wrong: Directory roles are in Entra ID, not Azure RBAC.
Custom roles
Custom roles can be created to meet specific needs.
Built-in roles
Built-in roles like Contributor are predefined.
Guest roles
Why wrong: There is no 'guest role' in Azure RBAC.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Service roles
Options B, C, and E are correct. Built-in roles (B), custom roles (C), and service roles (E) exist. Option A (Guest roles) is not a category. Option D (Directory roles) are for Entra ID, not Azure RBAC.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
