Microsoft Azure Architect Design (AZ-301) Practice Exam

Azure Key Vault is designed primarily to protect sensitive information such as cryptographic keys, secrets (like passwords and API keys), and certificates. It serves as a secure storage solution, allowing organizations to manage access to this sensitive data efficiently and securely. This ensures that only authorized applications and users can access the keys and secrets, which enhances the overall security posture of applications and services running in Azure.

The functionality of Azure Key Vault includes protecting information through encryption, providing auditing capabilities, and integrating seamlessly with Azure services to ensure that sensitive information is managed properly. By using Azure Key Vault, organizations can reduce the risks associated with managing sensitive information and comply with security standards and regulations.

The other options focus on different functionalities outside the primary scope of Azure Key Vault. Managing virtual networks pertains to Azure networking services, storing large files in the cloud relates to Azure Blob Storage, and facilitating machine learning models concerns Azure Machine Learning services. Each of these options serves distinct purposes that do not align with the primary capabilities of Azure Key Vault.
