EX294 Manage inventories and credentials Practice Question
Which THREE of the following are valid ways to define host variables in an Ansible inventory? (Choose exactly three.)
⚠ Common exam trap
Candidates often confuse runtime variable injection methods (like extra_vars or credentials) with static inventory variable definitions, leading them to select options that are valid for passing variables but not for defining host variables in an inventory.
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
✓
Inline in the inventory file, e.g., 'myhost ansible_host=192.168.1.1 http_port=8080'.
Ansible allows inline host variable definitions directly in the inventory file using key=value pairs after the hostname. This is a standard syntax where variables like 'http_port=8080' are assigned to the host 'myhost' and become available as Ansible facts during playbook execution. The 'ansible_host' special variable is also defined this way to override the connection address.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
In the 'extra_vars' field of the job template.
Why it's wrong here
Extra_vars are runtime overrides, not inventory definition.
- ✓
Inline in the inventory file, e.g., 'myhost ansible_host=192.168.1.1 http_port=8080'.
Why this is correct
Variables can be assigned directly in the inventory file.
- ✗
In a credential's 'Input Configuration' as a secret variable.
Why it's wrong here
Credentials define authentication, not host variables.
- ✓
In a 'group_vars/<groupname>' file, if the host belongs to that group.
Why this is correct
Group variables are inherited by hosts in the group.
- ✓
In a 'host_vars/<hostname>' file within the project.
Why this is correct
Standard Ansible method for per-host variables.
