- A
Azure RBAC for Kubernetes authorization
Why wrong: RBAC controls Kubernetes API access, not Azure resource access.
- B
Azure Policy for AKS
Why wrong: Policy enforces rules, not identity.
- C
Microsoft Entra Workload ID
Workload ID assigns an Azure AD identity to pods for secure access to Azure resources.
- D
Azure CNI network plugin
Why wrong: CNI provides networking, not identity.
Quick Answer
The answer is Microsoft Entra Workload ID, the AKS feature that enables pods to securely access Azure resources like Key Vault and SQL Database without service principals or connection strings. This feature, formerly known as Azure AD pod-managed identity, works by projecting a managed identity into each pod, allowing the pod to authenticate directly to Azure services via token exchange without hardcoding credentials. On the AZ-305 exam, this scenario tests your understanding of identity-based access for containerized workloads, often appearing as a distractor against Azure RBAC (which governs Kubernetes permissions, not Azure resource access), Azure Policy (compliance enforcement), or Azure CNI (networking). The key trap is confusing Kubernetes authorization with Azure resource authorization—remember that pods need an Azure identity, not a Kubernetes role. Memory tip: think “Workload ID = workload identity” for Azure resource access, while RBAC stays inside the cluster.
AZ-305 Design infrastructure solutions Practice Question
This AZ-305 practice question tests your understanding of design infrastructure 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.
A company is designing an Azure Kubernetes Service (AKS) cluster for a microservices application. They need to ensure that pods can securely access Azure resources such as Azure Key Vault and Azure SQL Database without using service principals or connection strings. Which AKS feature should they enable?
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
Microsoft Entra Workload ID
Azure AD pod-managed identity (now called Microsoft Entra Workload ID) allows pods to assume an identity to access Azure resources. Option A is wrong because Azure RBAC is for Kubernetes authorization. Option B is wrong because Azure Policy is for compliance. Option C is wrong because Azure CNI is for networking.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure RBAC for Kubernetes authorization
Why it's wrong here
RBAC controls Kubernetes API access, not Azure resource access.
- ✗
Azure Policy for AKS
Why it's wrong here
Policy enforces rules, not identity.
- ✓
Microsoft Entra Workload ID
Why this is correct
Workload ID assigns an Azure AD identity to pods for secure access to Azure resources.
Related concept
Authentication checks who the user is.
- ✗
Azure CNI network plugin
Why it's wrong here
CNI provides networking, not identity.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related AZ-305 questions on access control and AAA configuration.
