Before you interact with a Cloud Foundry deployment using the CLI, you have set the API endpoint. You can do this either with the cf api command or as part of the cf login command. Go ahead and set your API endpoint using:
cf api <API_ENDPOINT>
You should be able to see the endpoint you set by running:
cf api
Note:
cf targetwill also show you your current API endpoint.
The API endpoint and credentials for the exam will be provided in a text file located in the home directory you access via the browser-based terminal window.
Remember you can view the contents of a file using cat <some-file>. You can use this command to view the contents of the credentials files.
