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

Connect the roles in Pods and Multi-Container PatternsKeep pod boundary, application container, helper container, and shared network as separate workload roles.
Connect the roles in Pods and Multi-Container PatternsA topic-specific model connects four distinct roles used to reason about pods and multi-container patterns.
Pod groupGroup shares one scheduling lifecycle
Web processProcess serves the application request
Helper processProcess supports the primary workload
Pod networkNetwork gives containers one address space
Verify Shared filesConnect shared files with its topic-specific inspection, expected outcome, and protected workload boundary.
Verify Shared filesA verification model for pods and multi-container patterns connects the final workload decision to its check, result, and protected boundary.
Shared volumeVolume exchanges files between containers
