20+ practice questions focused on Manage containers — one of the most tested topics on the Red Hat Certified System Administrator EX200 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Manage containers PracticeA developer reports that a container running a custom web application is failing to start on a Red Hat Enterprise Linux 8 host. The container image is built from a Dockerfile that uses 'EXPOSE 8080'. The host firewall is enabled. Which action is most likely required to allow external access to the application?
Explanation: The container image's EXPOSE 8080 instruction is metadata that documents the intended port but does not actually publish it. To make the container's port 8080 accessible from the host's network, you must use the '-p 8080:8080' option when starting the container with 'podman run' or 'docker run'. This creates a port mapping from the host's port 8080 to the container's port 8080, allowing external traffic to reach the application.
Refer to the exhibit. A user attempts to start a new container named 'web3' but receives an error. The user wants to reuse the name 'web3'. Which command should be run first to resolve the issue?
Explanation: The error occurs because a container named 'web3' already exists, even if it is not running. To reuse the name, the existing container must be removed first. Option B, `podman rm web3`, removes the stopped container, freeing the name for a new container.
An administrator is tasked with deploying a containerized application on a Red Hat Enterprise Linux 8 server that is part of a high-security environment. The application must run as a non-root user inside the container. The container image is based on Red Hat Universal Base Image (UBI) and exposes port 443 for HTTPS. The administrator needs to ensure that the container can be restarted automatically if it crashes and that the application logs are persisted on the host in /var/log/app. The application requires a configuration file that is generated dynamically at startup and must be accessible to the container. The administrator has created a systemd service file for the container but wants to use Podman's built-in features to manage the container. Which approach meets all requirements?
Explanation: Podman's built-in restart policy (`--restart=always`) ensures the container restarts automatically after a crash without requiring systemd. The volume mount persists logs at /var/log/app on the host, and the port mapping exposes port 443. This approach uses Podman's native features as desired, meeting all requirements. Option A relies on a systemd service generated by Podman, which shifts management back to systemd instead of using Podman's built-in restart capability. Option B uses an invalid command. Option D uses `--restart=on-failure`, which only restarts on non-zero exit codes and may miss other crash scenarios.
A containerized application requires persistent storage and must be able to run with SELinux enforcing. The administrator runs a container with the volume mount: `podman run -v /host/data:/container/data:Z myimage`. Which TWO statements are true about this configuration?
Explanation: The `-v` flag with a bind mount persists the data in `/host/data` on the host filesystem even after the container is removed. The `:Z` flag tells Podman to relabel the host directory with a container-specific SELinux context, which is why Option E is also correct. This ensures the container can write to the mount point even when SELinux is enforcing.
An administrator needs to list all container images stored locally, including intermediate layers. Which command should be used?
Explanation: Both options B (`podman images --all`) and D (`podman images -a`) are correct because the `--all` flag (aliased as `-a`) instructs Podman to list all images in the local storage, including intermediate layers that are not tagged. Without this flag, only top-level (tagged) images are shown, which would omit the intermediate layers the administrator needs to see.
