Overview

The RHCA is the most senior system administration credential and is designed for technical leaders working in demanding enterprise environments.A Red Hat Certified Engineer (RHCE) who earns an RHCA certification brings an exceptional breadth and depth of knowledge to the biggest IT challenges. RHCA certification incorporates the skills and knowledge of a Red Hat Certified Datacenter Specialist (RHCDS) plus advanced networking services security, system monitoring, and performance tuning. To become certified, an RHCA will have demonstrated knowledge and skills in a number of areas beyond RHCE, such as those related to systems deployment, systems management, clustering, and storage management. However, the RHCA certification offers the flexibility to demonstrate additional skills in either directory services and authentication or in managing virtualized systems. Consequently, an RHCA will have many, but not necessarily all, of the following skills: Installing and configuring a Red Hat Network Satellite server

An RHCE is able to perform the following tasks (in addition to tasks associated with RHCSA):

Module 01:	Installing and configuring a Red Hat Network Satellite server
Module 02:	Configuring users, groups, administrators, and activation keys on a Satellite
Module 03:	Creating base and child channels on a Satellite

Module 06:	Configuring high-availability clusters using physical or virtual systems
Module 07:	Configuring a GFS file system to meet performance, size, and quota objectives
Module 08:	Configuring iSCSI targets and initiators
Module 09:	Configuring a Kerberos realm
Module 010:	Configuring Red Hat Directory Server to provide a centralized directory with access control
Module 11:	Configuring Red Hat Enterprise Linux clients to authenticate using various mechanisms, including Kerberos, LDAP, and Microsoft Active Directory
Module 12:	Configuring and managing hypervisors and virtual hosts using Red Hat Enterprise Virtualization
Module 13:	Analyzing system performance and behavior using tools such as vmstat, iostat, mpstat, and sar
Module 14:	Configuring systems to provide information using SNMP
Module 15:	Configuring runtime kernel parameters
Module 16:	Analyzing system and application behavior using ps, strace, top, Oprofile, and Valgrind
Module 17:	Configuring disk subsystems and scheduling algorithms and network buffers for optimal performance for specific requirements
