- A
Generate a random MAC address using `password` lookup with `mac` parameter
Correct. The `password` lookup with the `mac` parameter generates a random MAC address.
- B
Generate a random password using `password` lookup
Correct. The `password` lookup generates random passwords with configurable character sets and length.
- C
Execute a command on the remote host using `pipe` lookup
Why wrong: Incorrect. The `pipe` lookup executes a command locally on the control node, not on the remote host.
- D
Look up a value from an INI file using `ini` lookup
Correct. The `ini` lookup plugin retrieves values from INI files.
- E
Read the contents of a file using `file` lookup
Why wrong: Incorrect. While the `file` lookup is a valid plugin, it is not among the three correct uses for this question.
EX294 lookup plugins Practice Question
This EX294 practice question tests your understanding of transform data with filters and plugins. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: lookup plugins. 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 THREE are valid uses of lookup plugins in Ansible? (Select exactly three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Generate a random MAC address using `password` lookup with `mac` parameter
Option A is correct because the `password` lookup plugin supports the `mac` parameter to generate a random MAC address. Option B is correct because the `password` lookup plugin is used to generate random passwords. Option D is correct because the `ini` lookup plugin retrieves values from INI files. Option C is incorrect: the `pipe` lookup plugin executes a command locally on the control node, not on the remote host. Option E is incorrect because the `file` lookup plugin reads the contents of a file from the control node, but it is not considered one of the three valid uses in this context.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates often overlook the `mac` parameter of the `password` lookup plugin, assuming it only generates passwords. Additionally, the `pipe` lookup is frequently mistaken for executing commands on remote hosts, but it runs locally on the control node.

Command / output trap
Incorrect. The `pipe` lookup executes a command locally on the control node, not on the remote host.
Detailed technical explanation
How to think about this question
Lookup plugins in Ansible are executed on the control node and return data to the Ansible playbook, operating locally rather than on managed hosts. The `password` lookup plugin uses `/dev/urandom` or a cryptographically secure pseudo-random number generator (CSPRNG) to generate passwords, and it can store the generated password in a file for idempotency. The `ini` lookup plugin parses INI-style configuration files using Python's `configparser` module, while the `file` lookup plugin reads the entire contents of a file as a string, useful for embedding configuration data into templates or variables.
