The RHCT 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 RHCT certification brings an exceptional breadth and depth of knowledge to the biggest IT challenges. RHCT 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 RHCT 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 RHCT certification offers the flexibility to demonstrate additional skills in either directory services and authentication or in managing virtualized systems. Consequently, an RHCT will have many, but not necessarily all, of the following skills:
Configuring users, groups, administrators, and activation keys on a Satellite
Creating base and child channels on a Satellite
Using Cobbler and Satellite to install, configure, and manage systems
Managing data using logical volumes and snapshots
Configuring high-availability clusters using physical or virtual systems
Configuring a GFS file system to meet performance, size, and quota objectives
Configuring iSCSI targets and initiators
Configuring a Kerberos realm
Configuring Red Hat Directory Server to provide a centralized directory with access control
Configuring Red Hat Enterprise Linux� clients to authenticate using various mechanisms, including Kerberos, LDAP, and Microsoft Active Directory
Configuring and managing hypervisors and virtual hosts using Red Hat Enterprise Virtualization
Analyzing system performance and behavior using tools such as vmstat, iostat, mpstat, and sar
Configuring systems to provide information using SNMP
Configuring runtime kernel parameters
Analyzing system and application behavior using ps, strace, top, Oprofile, and Valgrind
Configuring disk subsystems and scheduling algorithms and network buffers for optimal performance for specific requirements
