Red Hat EX200 Passing Tips FYI:
As we all konw, the Red Hat EX200 has been updated from version 6 to version 7 NOW. There are MANY new topics in the RHEL 7 EX200 exam: the COMMANDS like NMCLI and so on.
Difference between RHEL 7 EX200 exam and RHEL 6 EX200 exam FYI:
1. systemctl VS init
2. journalctl in combination with syslog
3. gdisk VS fdisk
4. firewalld VS iptables
…etc.
When preparing for the Red Hat EX200 exam, I suggest you:
1. DO NOT only learn the RHEL 6 study materials, read the RHEL 7 study materials as much as possible.
2. Pay close attention to these objects:
(a) Configure a default software repository for your system
(b) Adjust the size of the Logical Volume
(c) Configure /var/tmp/fstab Permission
(d) Configure a cron Task
(e) Create a Shared Directory
(f) Configure NTP
(g) Add a swap partition
(h) Search files and string
(i) Create a logical volume
3. Reading the Red Hat official EX200 study guide carefully and deeply.
