Exam Vault Associate 002 topic 1 question 58 discussion

You manage two Vault dusters: “vaultduster1.acme.corp” and “vaultduster2.acme.corp”. You want to write a secret to the first Vaultcluster vaultcluster1.acme.corp and run vault kv put secret/foo value=‘bar’. The command times out and the error references the Vault cluster, “vaultcluster2.acme.corp”.
You run the command again with the following address flag:
vault kv put -address=‘https://vaultcluster1.acme.corp’ secret/foo value=‘bar’
The command completes successfully. You find that the terminal session defines the environment variable VAULT_ADDR=‘https://vaultcluster2.acxe.corp:8200’
Why was the second attempt successful?
