EX374 sample questions

Question 1

You are building a custom Execution Environment (EE) using `ansible-builder` version 3. You have a requirement to install a specific binary package, `libxml2-dev`, at the operating system level, and a Python library, `lxml`, via pip.

Which file should you create to define the OS-level dependencies, and how is it referenced in the `execution-environment.yml`?

Accepted Answer

Create `bindep.txt` for OS packages and reference it under `dependencies.system` in the definition file.

Answer

Define the packages directly in `ansible.cfg` under the `[builder]` section.

Answer

Create `requirements.txt` for OS packages and reference it under `dependencies.system`.

Answer

Create `os-packages.list` and reference it under `additional_build_steps.prepend`.

Question 2

A developer is writing a playbook that needs to push a configuration file to a remote server. However, the content of this file is generated by querying a local database on the control node.

Which combination of task configuration is required to ensure the database query runs locally, but the file creation happens on the remote target?

Accepted Answer

Use a `lookup` plugin to read the data inside a `template` or in the `content` parameter of a `copy` task.

Answer

Use the `shell` module to run a SQL query, register the output, and set `connection: local` for the entire playbook.

Answer

Configure the task with `delegate_to: localhost` and use the `template` module.

Answer

Use the `fetch` module with `delegate_to: localhost` to retrieve the data, then `copy` to the remote.

Question 3

You are managing a dynamic inventory sourced from AWS with the `amazon.aws.aws_ec2` plugin. You need to group instances by the value of their custom tag `Environment`, so that an instance tagged `Environment: prod` is placed in a group named `env_prod`.

Which configuration in your `aws_ec2.yml` plugin file achieves this?

Accepted Answer

keyed_groups:
- key: tags.Environment
prefix: env

Answer

groups:
Environment: "'Environment' in tags"

Answer

filters:
tag:Environment: "*"

Answer

compose:
groups: tags.Environment | default('ungrouped')

Question 4

You are reviewing a playbook that uses the `ansible.builtin.git` module. You notice the `update` parameter is set to `no`.

What is the specific effect of this configuration when the playbook runs multiple times?

Accepted Answer

It clones the repository only if it is missing; an existing clone is left as is, without pulling new commits.

Answer

The module will fail if the repository already exists.

Answer

The repository will be reset to the HEAD commit of the default branch on every run.

Answer

It runs `git fetch` to download new commits on each run but never merges them into the working tree.

Question 5

A system administrator needs to process a list of dictionaries containing network interface data.

Data structure:
```json
[
{"name": "eth0", "active": true, "speed": 1000},
{"name": "eth1", "active": false, "speed": 1000},
{"name": "eth2", "active": true, "speed": 100}
]
```

The goal is to extract ONLY the names of interfaces that are `active` and have a `speed` greater than 500.

Which Jinja2 filter chain produces the correct list `['eth0']`?

Accepted Answer

{{ interfaces | selectattr('active', 'equalto', true) | selectattr('speed', 'gt', 500) | map(attribute='name') | list }}

Answer

{{ interfaces | map(attribute='name') | selectattr('active', 'equalto', true) | selectattr('speed', 'gt', 500) | list }}

Answer

Answer

{{ interfaces | select('active') | select('speed', '>', 500) | list }}

Question 6

You have created a new Ansible Content Collection named `company.monitoring`. You need to build the collection artifact to upload it to your private Automation Hub.

Which command should you execute in the root directory of the collection?

Accepted Answer

ansible-galaxy collection build

Answer

ansible-galaxy collection init

Answer

ansible-builder build

Answer

ansible-playbook build.yml
