- A
Generate a self-signed certificate, upload it to AKS, and use ClientCertificateCredential in the code.
Why wrong: Incorrect: uses certificate, not managed identity.
- B
Deploy Azure AD Pod Identity (or Workload Identity) to assign a user-assigned managed identity to the pod. Use DefaultAzureCredential in the code. Grant the identity 'Listen' on Service Bus and 'Connect' on SQL Database.
Correct: uses managed identity and DefaultAzureCredential.
- C
Store Service Bus connection string and SQL connection string in Azure Key Vault. Use Key Vault SDK to retrieve them at runtime.
Why wrong: Incorrect: connection strings contain secrets, not managed identity.
- D
Create a service principal and store its client secret in a Kubernetes secret. Use ClientSecretCredential in the code. Assign the service principal permissions to Service Bus and SQL.
Why wrong: Incorrect: uses service principal with secret, not managed identity.
Quick Answer
The correct approach is to deploy Azure AD Pod Identity or Workload Identity to assign a user-assigned managed identity to the pod, then use DefaultAzureCredential in the code. This works because managed identities eliminate the need to manage service principals or secrets—the Azure Identity SDK automatically handles token acquisition from the AKS pod’s identity, granting the pod secure, scoped access to both Service Bus (with Listen permission) and Azure SQL Database (with Connect permission). On the AZ-204 exam, this scenario tests your understanding of how to implement passwordless authentication in microservices, often as a distractor against options using connection strings or service principal secrets. A common trap is assuming a system-assigned identity works without explicit pod-level assignment, but AKS requires Pod Identity or Workload Identity to bind the managed identity to the pod’s runtime. Memory tip: think “Pod Identity = Pod’s ID card” for both queue and database access.
AZ-204 Practice Question: Connect to and consume Azure services and third-party services
This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. 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.
Northwind Traders is building a microservices architecture on Azure Kubernetes Service (AKS). One service needs to read messages from an Azure Service Bus queue and write them to an Azure SQL database. The solution must use managed identities for authentication. The AKS cluster is integrated with Microsoft Entra ID. The development team wants to avoid managing service principals and secrets. The team has chosen to use the Azure Identity SDK for authentication. The service will run as a pod in AKS. Which approach should the team use to authenticate to Service Bus and Azure SQL Database?
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
Deploy Azure AD Pod Identity (or Workload Identity) to assign a user-assigned managed identity to the pod. Use DefaultAzureCredential in the code. Grant the identity 'Listen' on Service Bus and 'Connect' on SQL Database.
Use Azure AD Pod Identity or Workload Identity to assign a managed identity to the pod. The code uses DefaultAzureCredential to authenticate to both Service Bus (via Azure.Messaging.ServiceBus) and SQL (via Microsoft.Data.SqlClient). Option A is correct. Option B uses a service principal with secret, not managed identity. Option C uses connection strings. Option D uses certificate, not managed identity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
