Preparing for my RHCE exam

I am scheduled to take my RHCE exam later this month. Prior to the release of RHEL6, I felt fairly confident in my ability to pass, but now that they have released the new OS things have changed. Below is a list of the RHCE exam objectives (according to http://www.redhat.com/certification/rhce/objectives/). My hope is to methodically move through each and document the steps needed to accomplish them.

Exam Objectives

RHCE exam candidates should consult the RHCSA Exam Objectives document and be capable of RHCSA-level tasks, as some of these skills may be required in order to meet RHCE exam objectives. Red Hat reserves the right to add, modify and remove objectives. Such changes will be made public in advance through revisions to this document.
RHCE exam candidates should be able to accomplish the following without assistance. These have been grouped into several categories.

System Configuration and Management

  • Route IP traffic and create static routes
  • Use iptables to implement packet filtering and configure network address translation (NAT)
  • Use /proc/sys and sysctl to modify and set kernel run-time parameters
  • Configure system to authenticate using Kerberos
  • Build a simple RPM that packages a single file
  • Configure a system as an iSCSI initiator that persistently mounts an iSCSI target
  • Produce and deliver reports on system utilization (processor, memory, disk, and network)
  • Use shell scripting to automate system maintenance tasks
  • Configure a system to log to a remote system
  • Configure a system to accept logging from a remote system

Network Services

Network services are an important subset of the exam objectives. RHCE candidates should be capable of meeting the following objectives for each of the network services listed below:
  • Install the packages needed to provide the service
  • Configure SELinux to support the service
  • Configure the service to start when the system is booted
  • Configure the service for basic operation
  • Configure host-based and user-based security for the service
RHCE candidates should also be capable of meeting the following objectives associated with specific services:

HTTP/HTTPS

  • Configure a virtual host
  • Configure private directories
  • Deploy a basic CGI application
  • Configure group-managed content

DNS

  • Configure a caching-only name server
  • Configure a caching-only name server to forward DNS queries
  • Note: Candidates are not expected to configure master or slave name servers

FTP

  • Configure anonymous-only download

NFS

  • Provide network shares to specific clients
  • Provide network shares suitable for group collaboration

SMB

  • Provide network shares to specific clients
  • Provide network shares suitable for group collaboration

SMTP

  • Configure a mail transfer agent (MTA) to accept inbound email from other systems
  • Configure an MTA to forward (relay) email through a smart host

SSH

  • Configure key-based authentication
  • Configure additional options described in documentation

NTP

  • Synchronize time using other NTP peers

Hey great to know you have been preparing for your RHCE exams. Well I m too searching on some of the reviews that I can find on RHCE Certification. I planning for my younger brother to take this. Well.. I have found one and that RHCE Certification is in Bangalore. They say that Red Hat Certified Engineer Exam (EX300) is done to test & determine your skills & ability of becoming a senior system administrator. Performance based Red Hat Certified Engineer Exam tests determines if your knowledge, skill, and ability meet those required of a senior system administrator. Looking forward to it.
