Managing Basic Networking RHCSA Exam

This tutorial covers the topics related to the exam objective Manage Basic Networking. of the RHCSA EX200, RHSA EX124, and RHSA EX134 certification exams. The RHCSA EX200, RHSA EX124, and RHSA EX134 certification exams require that candidates know how to configure network interfaces, hostname resolution, and connect the system remotely. Candidates should be able to configure IPv4 and IPv6 settings on a network device. Additionally, they must know how to set up the system as a Domain Name Service (DNS) client so that it can resolve hostnames.

After completing essential networking configuration settings on a system, you can remotely connect to it, install packages from a repository, and configure network services. Starting from RHEL7, Red Hat removed many outdated tools and introduced many new tools to help manage networks. New tools effectively and efficiently work with network devices and network connection configurations. If you have worked with networking on RHEL 6 and earlier, you will notice that networking has changed in many aspects. Many approaches that were the default in previous versions either no longer work or have been changed. Red Hat certification programs require candidates to understand these changes.
