Red Hat Services Management and Automation with exam

Linux system administrators, site reliability engineers, and other IT professionals with some Ansible experience who are interested in learning how to manage and automate the deployment, configuration, and operation of key network services included with Red Hat Enterprise Linux 8.

In this course, you will learn key system administration skills needed to set up and provide network services that are frequently used by servers and their applications in enterprise data centers. You will gain an understanding of how to manually manage these services, and you will also prepare Ansible playbooks to automate manual configuration tasks and perform them at scale.

Manage network services

• Discuss and review key tools and skills needed to manage network services.

Configure link aggregation

• Improve the redundancy or throughput of network connections of servers by configuring Linux network teaming between multiple network interfaces.

Manage DNS and DNS servers

• Explain the operation of DNS service, troubleshoot DNS issues, and configure servers to act as a DNS caching nameserver or as an authoritative name server.

Manage DHCP and IP address assignment

• Explain and configure services used for IPv4 and IPv6 address assignment including DHCP, DHCPv6, and SLAAC.

Manage printers and printing files

• Configure systems to print to a network printer that supports IPP Everywhere, as well as manage existing printer queues.

Configure email transmission

• Discuss how mail servers operate, then configure a server to use system tools and Postfix to send email messages through an outbound mail relay.

Configure MariaDB SQL databases

• Discuss the basic operation of SQL-based relational databases, perform basic SQL queries for troubleshooting, and be able to set up a simple MariaDB database service.

Configure web servers

• Provide web content from Apache HTTPD or Nginx web servers, then configure them with virtual hosts and TLS-based encryption.

Optimize web server traffic

• Improve performance of your web servers by using Varnish to cache static content being served and HAProxy to terminate TLS connections and balance load between servers.

Provide file-based network storage

• Deliver simple file-based network shares to clients using the NFS and SMB protocols.

Access block-based network storage

• Configure iSCSI initiators on your servers to access block-based storage devices provided by network storage arrays or Ceph storage clusters.
