HashiCorp Vault-Associate Dumps Questions Answers

Not all storage backends support high availability mode for Vault. Only the storage backends that support locking can enable Vault to run in a multi-server mode where one server is active and the others are standby. Some examples of storage backends that support high availability mode are Consul, Integrated Storage, and ZooKeeper. Some examples of storage backends that do not support high availability mode are Filesystem, MySQL, and PostgreSQL. References: https://developer.hashicorp.com/vault/docs/concepts/ha 1, https://developer.hashicorp.com/vault/docs/configuration/storage 2

To make an authenticated request via the Vault HTTP API, you need to use the X-Vault-Token HTTP Header or the Authorization HTTP Header using the Bearer scheme. The token is a string that represents your identity and permissions in Vault. You can obtain a token by using an authentication method, such as userpass, approle, aws, etc. The token can also be a root token, which has unlimited access to Vault, or a wrapped token, which is a response-wrapping token that can be used to unwrap the actual token. The token must be sent with every request to Vault that requires authentication, except for the unauthenticated endpoints, such as sys/init, sys/seal-status, sys/unseal, etc. The token is used by Vault to verify your identity and enforce the policies that grant or deny access to various paths and operations. References: https://developer.hashicorp.com/vault/api-docs 3, https://developer.hashicorp.com/vault/docs/concepts/tokens 4, https://developer.hashicorp.com/vault/docs/concepts/auth 5

The Google Cloud Secrets Engine is the best option for the DevOps team to provision VMs in GCP via a CICD pipeline and integrate Vault to protect the credentials used by the tool. The Google Cloud Secrets Engine can dynamically generate GCP service account keys or OAuth tokens based on IAM policies, which can be used to authenticate and authorize the CICD tool to access GCP resources. The credentials are automatically revoked when they are no longer used or when the lease expires, ensuring that the credentials are short-lived and secure. The DevOps team can configure rolesets or static accounts in Vault to define the scope and permissions of the credentials, and use the Vault API or CLI to request credentials on demand. The Google Cloud Secrets Engine also supports generating access tokens for impersonated service accounts,which can be useful for delegating access to other service accounts without storing or managing their keys1.

The Identity Secrets Engine is not a good option for this use case, because it does not generate GCP credentials, but rather generates identity tokens that can be used to access other Vault secrets engines or namespaces2. The Key/Value Secrets Engine version 2 is also not a good option, because it does not generate dynamic credentials, but rather stores and manages static secrets that the user provides3. The SSH Secrets Engine is not a good option either, because it does not generate GCP credentials, but rather generates SSH keys or OTPs that can be used to access remote hosts via SSH4.
