UNTIMED COACHING

Practice before the pressure

Use feedback to correct the model, not merely memorize an option position.

GUIDED PRACTICE

Practice the lesson questions

Answer normal lesson questions without a timer. Every answer includes an explanation, and incorrect answers can be tried again before continuing.

CONCEPT MODELS

See the lesson as a system

Use these visual guides to connect the key ideas before answering the questions.

Connect the roles in Run, Stop, Inspect, and Remove ContainersKeep image reference, container identity, runtime state, and inspection evidence as separate workload roles.
Connect the roles in Run, Stop, Inspect, and Remove ContainersA topic-specific model connects four distinct roles used to reason about run, stop, inspect, and remove containers.
Image packagePackage supplies the container filesystem
Container recordRecord separates name and unique ID
Running processProcess changes through lifecycle states
State inspectionInspect exposes configuration and exit data
Verify Removal boundaryConnect removal boundary with its topic-specific inspection, expected outcome, and protected workload boundary.
Verify Removal boundaryA verification model for run, stop, inspect, and remove containers connects the final workload decision to its check, result, and protected boundary.
