LPIC306 (High Availability and Storage Clusters) - Linux Professional Institute (306-500)

The LPIC-3 306 High Availability and Storage Clusters certification, offered by the Linux Professional Institute (LPI), is an advanced, vendor-neutral credential that validates expertise in building and maintaining highly available, fault-tolerant Linux systems. As part of the LPIC-3 specialty track, it requires passing the LPIC-3 306 exam (exam code 306-500) and holding an active LPIC-2 certification. This course equips Site Reliability Engineers (SREs) and system administrators with the skills to architect resilient infrastructure, leveraging native Linux solutions for high availability clusters, distributed storage, and single-node reliability. It prepares you to design and manage robust systems capable of withstanding failures and ensuring operational continuity.
