Build resilient Linux services with our Classroom and Online RH436 | EX436 Training at WebAsha Technologies. It develops the hands-on high-availability and storage skills validated by the performance-based EX436 exam.
Training overview:
The RH436 EX436 training focuses on implementing high availability on Red Hat Enterprise Linux with the High Availability Add-on: building Pacemaker clusters, configuring fencing, managing resources and constraints, and using shared storage with HA-LVM and GFS2. In real cluster labs you practise keeping services running under exam conditions.
Intended audience:
This course is ideal for senior Linux administrators, infrastructure and storage engineers and SREs who build and operate highly available services on Red Hat Enterprise Linux.
Topics covered:
-
Build Pacemaker clusters: Create and manage clusters with Pacemaker and corosync.
-
Configure fencing (STONITH): Set up fencing devices to protect data integrity.
-
Manage resources & constraints: Define resources, groups, order and colocation constraints.
-
Manage quorum: Configure quorum and handle node failures.
-
Shared storage: Provide shared storage with iSCSI and multipath.
-
HA-LVM: Configure HA-LVM for highly available block storage.
-
GFS2 clustered filesystem: Deploy and manage the GFS2 clustered filesystem.
-
Highly available services: Build application and storage services that survive node failures.
Requirements:
Learners should have RHCE-level Linux administration skills. Online participants need a stable internet connection and a laptop/desktop for the live cluster labs, where most of the EX436 practice happens.
Pre-requisites:
Red Hat recommends RHCSA and RHCE-level Linux administration experience before RH436/EX436.
Career benefits:
Employers look for EX436-certified professionals who can keep infrastructure running through failures. In India, packages typically range from ₹6 LPA to ₹26+ LPA in roles such as Linux Administrator, Infrastructure Engineer and SRE, with a path toward the RHCA.
