The Network+ exam expects you to have a good understanding of concepts related to computer networks. Hands-on experience is recommended and is good to have. You should be very familiar with network terminology, protocols, and standards, and you should have basic troubleshooting skills. You will need to review the Study Guide and pay close attention to the areas that are new for you or that you feel uncomfortable with.
This section includes some exercises that you can perform either on a standalone computer or in a network to gain some hands-on experience. Since the Network+ exam mainly covers foundation-level knowledge of computer networking, you are not expected to know how to configure a particular type of hardware or an application. However, you must have essential basic knowledge, such as identification of network topology, cables, and connectors.
It is recommended that you do not perform any of the suggested exercises in your organization or in any running computer network. Create a test environment consisting of two computers for completing these exercises. Even if you just want to view network settings in a production environment, make sure a senior administrator accompanies you. In any case, you should follow the policies of the organization.
