Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
podman ps --processes worker_node
Why it's wrong here
podman ps does not take a --processes flag.
- ✗
podman exec worker_node ps -ef
Why it's wrong here
While podman exec can run ps inside the container, podman top is the native tool designed specifically for this purpose without needing shell execution inside the container.
- ✗
podman inspect --processes worker_node
Why it's wrong here
podman inspect does not provide a process list via a flag.
- ✓
podman top worker_node -ef
Why this is correct
podman top accepts standard ps options after the container name to customize output.
