I wanted to give my feedback as to why this is a great learning path for anyone who is interested in learning Linux architecture in detail or if their job demands handling/administrating  or troubleshooting complex linux production environments.

For learners who want to go deep into Linux troubleshooting , It is good choice after you have done RHCE.

The skills and knowledge covered in the EX342 certification (course code RH342)  can provide Linux L2/L3 admins with valuable knowledge and tools to effectively diagnose and troubleshoot issues related to Linux systems. Here are some specific reasons why learning this material can be important:

  1. Improve system performance: Linux admins who have a deep understanding of Linux diagnostics and troubleshooting can better identify and fix issues that may be affecting system performance. This can help ensure that Linux systems are operating optimally and efficiently.

  2. Reduce downtime: When issues arise with Linux systems, it can be critical to quickly identify and resolve them to minimize downtime. By having the skills and knowledge covered in the EX342 certification, Linux admins can more effectively diagnose and fix issues, leading to less downtime and improved system availability.

  3. Cloud learning path: Cloud providers such as AWS, Microsoft Azure, and Google Cloud Platform offer Linux-based virtual machines and containers that run on their cloud infrastructure. Having a strong understanding of Linux diagnostics and troubleshooting can help individuals who are learning cloud computing to better manage and troubleshoot Linux systems in the cloud.

  4. Kubernetes (K8s) path: Kubernetes is a popular container orchestration tool that is commonly used in cloud-native environments. Linux is the primary operating system used by Kubernetes nodes, and a deep understanding of Linux diagnostics and troubleshooting is critical for effectively managing and troubleshooting Kubernetes clusters.

  5. Enhance career prospects: Earning the EX342 certification can demonstrate to potential employers and clients that a Linux  admin has a strong understanding of Linux diagnostics and troubleshooting. This can help to enhance their career prospects and open/scale up new job opportunities.

  6. Keep up with industry trends: The Linux industry is constantly evolving, and it's important for Linux  admins to stay up-to-date with the latest technologies and best practices. Learning the material covered in the EX342 certification can help to ensure that they are staying current and competitive in the job market.

The ROL course offering related to this course RH342 covers all the details of the tools and technology in a very organised and detailed manner. I highly recommend the course to anyone pursuing this certification. 

The exam is based on RHEL 8.4.

This exam is counted towards the RHCA skill path.
