Which of the following is NOT a feature of OCI Vault?

OCI Vault is primarily designed to secure and manage sensitive information such as encryption keys and secrets. Its key features include key management, secret storage, and data encryption management.

Key management refers to the functionality that allows users to create, store, and manage encryption keys used to secure data. Secret storage provides a secure location for managing sensitive information like passwords, tokens, and API keys. Data encryption management involves overseeing the encryption of data at rest and in transit, ensuring that sensitive data is protected.

Virtual network creation, on the other hand, pertains to OCI's networking capabilities, such as setting up Virtual Cloud Networks (VCNs) that allow users to define their networking environment. While networking is essential to the overall cloud infrastructure, it does not fall under the functionalities provided by OCI Vault, which is focused specifically on security and data protection. Thus, virtual network creation is correctly identified as not a feature of OCI Vault.
