@Dave_ross You are mostly right about differences between EX280v4.14 & EX280v4.18!
Approx 90% of the objectives are same in both exams.
Examples from EX280v4.14 but not in the EX280v4.18 objectives :
Assess the health of an OpenShift cluster (explicitly called out in 4.14)
Roll back failed deployments
Manage image streams & use triggers
Provision persistent storage volumes and use storage classes
Configure health probes and application compute limits
Scale applications to meet demand
Work with operators like MetalLB and Multus
Update OpenShift and deprecated API usage
v4.18 emphasizes modern Kustomize/YAML over v4.14's storage heavy legacy focus but both are performance-based with persistent configs.
While your overall preparation for the EX280 exam won't change radically between versions 4.14 and 4.18, as most of the core administrative skills tested remain the same, there is one key difference. The newer version, 4.18, formally structures its objectives more heavily around declarative practices and modern YAML workflows. This means you should focus less on older, mixed, or imperative command-line forms and prioritize managing the environment primarily through configuration files.
