An RHCE® certification is earned by a Red Hat® Certified System Administrator (RHCSA) who has demonstrated the knowledge, skill, and ability required of a senior system administrator responsible for Red Hat Enterprise Linux® systems. Professionals holding this certification have continually helped their companies with successful deployments and migrations.
An RHCE is able to perform the following tasks (in addition to tasks associated with RHCSA):
Configuration of static routes, packet filtering, and network address translation
Setting kernel runtime parameters
Building simple RPMs
Configuring an iSCSI initiator
Producing and delivering reports on system utilization
Using shell scripting to automate system maintenance tasks
Configuring system logging, including remote logging
Configuring a system to provide networking services, including HTTP/HTTPS, FTP, NFS, SMB, SMTP, SSH, and NTP
Hiring IT professionals who are certified as RHCEs allows many organizations to increase their ratio of servers to administrators, enabling them to be more cost effective in building out their infrastructures without needing to bring on additional resources.
