Now that we have a good idea of how to authenticate and scope ourselves to a specific project with Keystone via the Horizon dashboard and CLI, let's take a look at the exam objectives.
Figure 3.12 breaks down various objectives from the official objective list shown in Chapter 1, Introducing OpenStack and the Certified OpenStack Administrator Exam, and are available at http://www.openstack.org/coa/requirements. As you can see, a majority of the tasks can be completed via the Horizon dashboard, but there are still some that must be done via the CLI. You will find that many of the dashboard objectives are extremely intuitive, while some of the CLI objectives require a little more research.
