AZ-305 Practice Question: Design identity, governance, and monitoring solutions
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 TWO are valid methods to authenticate to Azure from a PowerShell script that runs unattended? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Service principal with a certificate
A service principal with a certificate is a valid unattended authentication method because the certificate can be securely stored (e.g., in Azure Key Vault or the local machine store) and used by the script without interactive login. The Azure PowerShell cmdlet `Connect-AzAccount -ServicePrincipal -CertificateThumbprint` or `-ApplicationId` with the certificate allows the script to authenticate using the certificate's private key, which is a non-interactive, secure approach.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Managed identity is only for resources hosted in Azure.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse managed identities as a universal authentication method for any script, but they only work when the script runs on an Azure resource that supports managed identities, not from arbitrary or on-premises environments.
Detailed technical explanation
How to think about this question
Under the hood, service principal authentication uses the OAuth 2.0 client credentials grant flow, where the script presents the client ID and a certificate (or secret) to Azure AD's token endpoint (`https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token`) to obtain an access token. Certificates are preferred over secrets in production because they can be rotated more securely and are less prone to accidental exposure; the certificate's thumbprint is used to locate the private key in the certificate store, and Azure AD validates the signed JWT assertion. In real-world scenarios, organizations often use certificate-based service principals in CI/CD pipelines (e.g., Azure DevOps, GitHub Actions) to deploy resources without storing plaintext secrets.

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.
