Final answer:
To retrieve security tokens, an application must connect to Azure Active Directory, which is a service for identity and access management in Microsoft Azure.
Step-by-step explanation:
To retrieve security tokens, an application should connect to Azure Active Directory (AAD). AAD is a cloud-based identity and access management service provided by Microsoft Azure that helps your employees sign in and access resources such as applications, networks, and databases. Applications use services like AAD to authenticate users and obtain tokens that grant access to protected resources. Azure Monitor is used for performance and health monitoring of applications, Azure Key Vault is used for managing secrets and cryptographic keys, and Azure Storage is used for storing large amounts of data.
