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 Network Policies and Workload SecurityKeep policy target, ingress rule, egress rule, and default deny as separate workload roles.
Connect the roles in Network Policies and Workload SecurityA topic-specific model connects four distinct roles used to reason about network policies and workload security.
Pod selectorDecision chooses protected payments Pods
Ingress connectionConnection permits named sources and ports
Egress networkNetwork permits named outbound destinations
Traffic deniedDeny blocks traffic not explicitly allowed
Verify Pod securityConnect pod security with its topic-specific inspection, expected outcome, and protected workload boundary.
Verify Pod securityA verification model for network policies and workload security connects the final workload decision to its check, result, and protected boundary.
