Your company plans to automate server deployments to Azure. Your manager is concerned administrative credentials might be exposed during deployment. Which Azure solution should you recommend to encrypt those credentials during deployment?

Azure Key Vault is the correct solution because it securely stores and manages sensitive information like cryptographic keys, secrets (such as passwords and connection strings), and certificates. During automated deployments, credentials can be retrieved from Key Vault without being hardcoded or exposed in scripts, thus encrypting and protecting them. Azure Information Protection focuses on data classification and protection, not credential storage. Azure Security Center provides unified security management and threat protection, but doesn't store credentials. Azure Multi-Factor Authentication adds a layer of identity verification but doesn't secure credentials during automated processes.
