The Linux exams of Linux Foundation and RedHat are performance based. To pass you must practise. Sander van Vugt offers an lab environment created with VMware fusion. He offers two versions
- V2.0, available for download at http://rhatcert.com or through the book’s website at http://pearsonitcertification.com.
- V3.0 is available through http://rhatcert.com only.
- You can also create the lab environment from scratch with Vagrant and Ansible RHCSA RHCE Lab environment.
You can run these lab environments in VMware Fusion/Workstation, in virtualBox or on Linux import them in LVM.
| Pro | Con | |
|---|---|---|
| V2.0 | 1) has CentoS 7.1 similar to some exams, eg nmcli v 0.9 |
1) yum update takes long & probably fails 2) needs little tweaking for alls labs to work |
| V3.0 | 1) updates from private repository 1511 2) Sander recommends this version |
1) you'd never practised with 7.0.1406 2) needs little tweaking for alls labs to work |
| Vagrant | 1) always latest CentoS version, updates to 7.3 automatically 2) works out of the box 3) could be adapted for certdepot |
1) you'll probably not see this RHEL version on the exam 2) no support for Virtualization labs 3) you'd never practised with 7.0.1406 |

sudo route -n delete 192.168.4.0/24
open -a VMware\ Fusion; sleep 5
netstat -rn | grep -e 192.168.4 -e Destination
