You are using Azure Key Vault for the auto-unseal configuration on your cluster. After the Vault service restarts, what command must you run to…

Comprehensive and Detailed in Depth

When using Azure Key Vault for auto-unseal, no manual command is required to unseal Vault after a

service restart. The HashiCorp Vault documentation states: "Vault supports opt-in automatic

unsealing via cloud technologies: AliCloud KMS, AWS KMS, Azure Key Vault, Google Cloud KMS, and

OCI KMS. This feature enables operators to delegate the unsealing process to trusted cloud providers

to ease operations in the event of partial failure and to aid in the creation of new or ephemeral

clusters." Specifically, for Azure Key Vault, "the auto-unseal feature automatically handles the

unsealing process," eliminating the need for manual intervention.

The documentation further explains: "When configured with auto-unseal, Vault will automatically

unseal itself upon startup using the configured key management service, provided the necessary

permissions and credentials are in place." Options like vault operator unseal are for manual

unsealing, vault operator members lists cluster members, and vault operator init initializes Vault—

none apply to auto-unseal scenarios. Thus, A is correct.
