This EX200 practice question tests your understanding of manage containers. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Exhibit
Refer to the exhibit.
$ podman ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

Based on the exhibit, which command should be used to start the container named 'mycontainer'?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
Refer to the exhibit.
$ podman ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a1b2c3d4e5f6 registry.access.redhat.com/ubi8/ubi "/bin/bash" 5 minutes ago Exited (0) 3 minutes ago mycontainer

A
podman attach mycontainer
Why wrong: Attach only works on running containers.
B
podman restart mycontainer
Why wrong: Restart requires the container to be running; this container is exited.
C
podman run mycontainer
Why wrong: This tries to create and run a new container, but 'mycontainer' is an existing container name, so it would conflict.
D
podman start mycontainer
Correct. This starts the existing container that exited.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
podman start mycontainer
The correct command to start an existing but stopped container is 'podman start mycontainer'. 'podman start' resumes a container that has been created (via 'podman create') or previously stopped, without creating a new instance. Option D is correct because it directly addresses the requirement to start the container named 'mycontainer' that already exists.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'podman run' (which creates and starts a new container) with 'podman start' (which starts an existing stopped container), leading them to choose option C when the container already exists.
Detailed technical explanation
How to think about this question
Under the hood, 'podman start' sends a start signal to the container's process (typically the init process with PID 1 inside the container's cgroup/namespace), resuming its execution from a stopped state. This is distinct from 'podman run', which performs a full container lifecycle: pulling the image (if needed), creating the container's layers and namespaces, and then starting it. In real-world scenarios, you might use 'podman start' to resume a long-running service container after a host reboot, avoiding the overhead of re-creating the container's filesystem and configuration.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the EX200 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
