The correct answer is to create a security domain for each tenant and assign the 'tenant-admin' role to the user within that domain. This works because Cisco ACI enforces Role-Based Access Control (RBAC) through security domains, which act as logical boundaries that restrict a user’s permissions to only the objects—such as EPGs, contracts, and policies—within their assigned domain. By mapping a tenant to its own security domain and granting the tenant-admin role there, you achieve strict traffic isolation without granting cross-tenant or global privileges. On the Cisco DCCOR 350-601 exam, this scenario tests your understanding of how ACI RBAC security domains prevent privilege escalation in multi-tenant fabrics; a common trap is assuming a global admin role is needed for tenant management. Remember the memory tip: “One tenant, one domain, one role—keep the admin in their own hole.”
350-601 Security Practice Question
This 350-601 practice question tests your understanding of security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 customer is deploying Cisco ACI with a requirement to isolate tenant traffic in a multi-tenant environment. They want to ensure that a tenant admin can only manage their own tenant's objects. Which RBAC configuration should be implemented?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a security domain for each tenant and assign the 'tenant-admin' role to the user within that domain.
Option C is correct because Cisco ACI uses security domains to enforce Role-Based Access Control (RBAC) boundaries. By creating a security domain for each tenant and assigning the 'tenant-admin' role to a user within that domain, the tenant admin is restricted to managing only the objects (e.g., EPGs, contracts, policies) that belong to that specific tenant. This ensures isolation of tenant traffic management in a multi-tenant environment without granting global or cross-tenant privileges.
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.
✗
Assign the 'read-only' role to the user within the tenant.
Why it's wrong here
Read-only does not allow management.
✗
Create a separate VRF for each tenant and assign admin to that VRF.
Why it's wrong here
VRF is for network isolation, not RBAC.
✓
Create a security domain for each tenant and assign the 'tenant-admin' role to the user within that domain.
Why this is correct
Security domains limit the scope of roles to specific tenants.

✗
Assign the 'tenant-admin' role to the user globally.
Why it's wrong here
Global role gives access to all tenants.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between network-level segmentation (e.g., VRFs) and administrative-level isolation (e.g., security domains), and the trap here is that candidates mistakenly choose VRF-based isolation for RBAC, not realizing that VRFs only separate data plane traffic, not management access.
Detailed technical explanation
How to think about this question
In Cisco ACI, security domains are mapped to tenants and provide a hierarchical RBAC model where roles are scoped to specific domains. The 'tenant-admin' role, when assigned within a domain, leverages the APIC's role-based access control lists (RBACLs) to enforce read-write permissions only on objects within that domain's scope. This is critical in multi-tenant environments to prevent accidental or malicious cross-tenant configuration changes, such as modifying contracts or EPGs that could affect other tenants' traffic isolation.

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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
