Red Hat Enterprise Deployment and Systems Management (RH401)

I’m one step closer to both the Red Hat Certified Datacenter Specialist and Red Hat Certified Architect certificates after passing the Red Hat EX401 exam last week. The RH401/EX401 covers Red Hat deployments and their Satellite server software. Satellite provides Red Hat Network services at a local level for companies that have large installations of Red Hat servers. It also uses Cobbler, PXE boot, and Kickstart files to run automated deployments. A Kickstart file is a template for the initial installation of a Linux box. It sets everything from the partitioning scheme, to installed software and settings, to how to handle the installation and scripts to run after the installation is completed. Kickstart’ing a bare metal machine can yield a fully operational and configured Linux server in around 10 minutes. It is certainly one of the more interesting topics for me.
