VA-002-P Exam Dumps : HashiCorp Certified: Vault Associate

Within each datacenter, we have a mixture of clients and servers. It is expected that there be between three to five servers. This strikes a balance between availability in the case of failure and performance, as consensus gets progressively slower as more machines are added. However, there is no limit to the number of clients, and they can easily scale into the thousands or tens of thousands.

Server or Leader - It indicates whether the agent is running in server or client mode. Server nodes participate in the consensus quorum, storing cluster state, and handling queries. At any given time, the peer set elects a single node to be the leader. The leader is responsible for ingesting new log entries, replicating to followers, and managing when an entry is considered committed.

Client or Follower - Client nodes make up the majority of the cluster, and they are very lightweight as they interface with the server nodes for most operations and maintain a very little state of their own.

When reading a dynamic secret, such as via vault read, Vault always returns a lease_id. This is the ID used with commands such as vault lease renew and vault lease revoke to manage the lease of the secret.

vault lease lookup

Usage: vault lease [options] [args]

This command groups subcommands for interacting with leases. Users can revoke or renew leases.

Renew a lease:

$ vault lease renew database/creds/readonly/2f6a614c...

Revoke a lease:

$ vault lease revoke database/creds/readonly/2f6a614c...

Subcommands:

renew Renews the lease of a secret

revoke Revokes leases and secrets

The terraform state command is used for advanced state management. Rather than modify the state directly, the terraform state commands can be used in many cases instead.
