For RHCT and RHCE exam questions, you should know about networking as it is required for these exams under Networking configuration :

  • network card/device is recognised as eth0 in redhat linux and other flavours of linux
  • ifconfig eth0 will display ip address for network interface
  • you should expect questions in RHCE/RHCT exam to bring up and down network interface:
    • ifup eth0
    • ifdown eth0
  • For RHCT/RHCE exam question you should know network configuration files:
    • /etc/sysconfig/network-scripts/ifcfg-eth0 is network configuration file
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.30.29
NETMASK=255.255.255.0
GATEWAY=192.168.30.1
    • For RHCT/RHCE exam you should know how to change static ip to dhcp
    • Simply change BOOTPROTO to dhcp from none
  • you can also run system-config-network to change these settings by GUI but for RHCT and RHCE exam you should know how to change network setting using command line that will save time as time is critical in RHCT and RHCE exams.
