Which THREE methods or directives can be used to pass environment variables into containers via Podman Compose? (Choose three.)

An administrator needs to run a container that shares the host's network namespace directly so it can listen on privileged ports without port forwarding. Which Podman command flag achieves this network mode?

You are troubleshooting a container that should have no network access whatsoever for security isolation. Which networking option should you apply?

A containerized web service must be accessible from the host system on TCP port 8080, while the application inside the container listens on port 80. Which flag correctly configures this port mapping?

An operator wants to create a custom user-defined bridge network named 'app-net' with a specific subnet of '192.168.100.0/24' using Podman. Which command is correct?

Two containers running on the same custom user-defined bridge network need to communicate with each other. What built-in mechanism allows them to resolve each other by container name?

An administrator needs to inspect the configuration details, including subnet and gateway, of an existing custom network named 'my-net'. Which command should be executed?

You are deploying a container and want to bind its published port exclusively to the loopback interface (127.0.0.1) on the host to prevent external network access. Which syntax is correct?

An administrator needs to connect an already running container named 'web1' to an existing user-defined network named 'backend-net' without restarting the container. Which command accomplishes this?

You have a Kubernetes YAML manifest file named 'app.yaml' that defines a Pod with network settings. You want to deploy this directly as a Podman container/pod on your local system. Which command should you use?
