Explanation

IOx is Cisco's application hosting framework that must be enabled before Docker containers can run on IOS-XE devices like the Catalyst 9300. Without iox enabled globally, the underlying container runtime isn't started, so no app-hosting configuration will work - the Docker engine simply isn't active.

Why the distractors are wrong:

• A (app-hosting appid docker) defines an application hosting profile for a specific app, but this is meaningless if IOx itself isn't running first.
• B (app-resource docker) is a sub-command within an app-hosting config context used to assign resources (CPU/memory) to an app - not a top-level enablement command.
• C references a deeply nested VLAN access IP configuration context, which is unrelated to enabling the Docker runtime.

Memory tip: Think of IOx as the "ignition key" - you must turn it on (iox) before any app-hosting configuration commands have any effect. If the container isn't running at all, the problem is always at the foundation: IOx is off.
