CTLA case studies

The CTLA credential is aimed at Linux administrators who want independent evidence that they can run and support real systems rather than recite commands. It is a multiple-choice exam organized around eight weighted domains: Linux system administration (20%), shell scripting and command-line tools (15%), networking fundamentals and configuration (15%), security fundamentals and system hardening (15%), storage, filesystems and backup (10%), service management and process control (10%), virtualization and cloud concepts (10%), and troubleshooting and operational procedures (5%). The weighting tells you where to spend your time: core administration, scripting, networking and hardening together account for roughly two-thirds of the blueprint, so a candidate who is strong only at installing packages and editing configuration files will find the margin thin. Preparation should be hands-on. The CTLA case studies are 5 cases and about 3,416 words.
