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.
Which TWO options to podman run can be used to persist data outside the container? (Select exactly two.)
--mount
Also creates mounts, with more options.
--read-only
Why wrong: Makes rootfs read-only, does not persist data.
--tmpfs
Why wrong: Mounts a temporary filesystem, data is not persistent.
-v
Creates a bind mount or volume.
--squash
Why wrong: Not a valid podman run option.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
--mount
The `--mount` option (A) and `-v` (D) are both used to mount host directories or volumes into a container, allowing data to persist outside the container's writable layer. `--mount` provides a more explicit syntax for specifying mount type, source, and destination, while `-v` is a shorter alias for `--volume` that also binds host paths or named volumes. Both ensure data survives container removal.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Red Hat often tests the distinction between ephemeral storage options like `--tmpfs` and persistent storage options like `--mount`/`-v`, and candidates mistakenly select `--tmpfs` thinking it persists data because it is writable, but it is memory-backed and lost on container stop.
Detailed technical explanation
Under the hood, `-v` and `--mount` both leverage the kernel's bind mount mechanism (via the `mount` syscall) to attach a host directory or a volume managed by Podman's volume store into the container's mount namespace. A subtle behavior is that `--mount` supports advanced options like `bind-propagation` (e.g., `rslave`) and `volume-opt`, which `-v` does not expose directly. In real-world scenarios, using `--mount` is preferred in scripts for clarity and to avoid ambiguity with named volumes.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
