The answer is Azure Key Vault, Managed Identities, and Key Vault key rotation policy. This combination meets all three security requirements because Key Vault encrypts secrets at rest and provides full audit logging via diagnostic settings, Managed Identities enable Azure DevOps pipeline tasks to authenticate to Key Vault without ever storing credentials in variables or code, and a Key Vault key rotation policy automates secret renewal for supported types like storage account keys or certificates. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of how to integrate Azure DevOps with Azure security services rather than relying on pipeline-level secrets or Azure AD, which are common traps—pipeline secrets lack centralized management and rotation, while Azure AD is an identity provider, not a secret store. A useful memory tip is “KVM: Key Vault, Managed Identity, rotation” to recall the three pillars of secure secret lifecycle management in CI/CD.
SC-100 Practice Question: Design security solutions for applications and data
This SC-100 practice question tests your understanding of design security solutions for applications and data. 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.
Your organization uses Azure DevOps for CI/CD. You need to ensure that secrets (e.g., API keys) used in pipeline tasks are securely stored and accessed. The security requirements are: secrets must be encrypted at rest, access must be audited, and secrets must be automatically rotated. Which THREE services or features should you use? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Key Vault access policy to grant permissions.
Azure Key Vault provides encrypted storage for secrets with access auditing. Managed identities allow secure access without storing credentials. Key Vault supports automatic rotation for some secret types. Azure DevOps Variable Groups can link to Key Vault but do not provide rotation. Azure AD is not a secret store. Pipeline secrets are not centrally managed. Options A, B, and C together meet all requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Azure DevOps Variable Groups to store secrets.
Why it's wrong here
Variable groups store secrets but do not provide rotation or centralized auditing.
✓
Azure Key Vault to store secrets.
Why this is correct
Key Vault encrypts secrets at rest and provides access logs.
Related concept

✗
Azure Active Directory service principal to access secrets.
Why it's wrong here
Service principals are identities, not secret storage; managed identity is better for auditing.
✓
Azure Key Vault key rotation policy.
Why this is correct
Key Vault supports automatic rotation for keys and secrets.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Variation 1. Your organization is implementing a secure DevOps pipeline for Azure. You need to ensure that secrets (e.g., API keys) are not stored in source code and that access to production resources is controlled. Which THREE practices should you implement?
hard
A.Store secrets in Azure DevOps pipeline variables with encryption enabled
✓ B.Use Azure Key Vault to store secrets and retrieve them at deployment time
✓ C.Use Azure DevOps variable groups linked to Azure Key Vault
D.Store secrets in a configuration file in a private Git repository
✓ E.Use managed identities for Azure resources to authenticate to Key Vault
Why B: Options A, B, and D are correct. Using Azure Key Vault for secrets, managed identities for Azure resources, and Azure DevOps variable groups linked to Key Vault are all secure practices. Option C is wrong because storing secrets in pipeline variables with encryption is not as secure as Key Vault. Option E is wrong because hardcoding secrets in configuration files is insecure.
