What is the primary function of Azure Key Vault?

The primary function of Azure Key Vault is to safeguard cryptographic keys and secrets used by cloud applications and services. This service provides a secure storage solution for sensitive information like API keys, passwords, certificates, and cryptographic keys, which are crucial for maintaining the security of applications and services in the cloud.

Using Azure Key Vault helps protect this sensitive data through robust security controls, such as access policies and the ability to audit access. By centralizing the management of keys and secrets, it simplifies the security management process and ensures that only authorized applications and users can access sensitive information. This can help organizations adhere to compliance requirements and manage their security posture more effectively.

The other options presented focus on different functionalities within the Azure ecosystem, such as web applications, network creation, and data analysis, which are not aligned with the specific purpose of Azure Key Vault.
