EX294 Manage task execution and roles Practice Question

This EX294 practice question tests your understanding of manage task execution and roles. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

Exhibit

[root@control ansible]# cat ansible.cfg
[defaults]
host_key_checking = False
inventory = ./inventory
roles_path = ./roles

[inventory]
enable_plugins = host_list, script, auto, yaml, ini, toml

[privilege_escalation]
become = True
become_method = sudo
become_user = root
become_ask_pass = False

[root@control ansible]# cat inventory
[webservers]
web1 ansible_host=192.168.1.10 ansible_user=admin
web2 ansible_host=192.168.1.11 ansible_user=admin

[dbservers]
db1 ansible_host=192.168.1.20 ansible_user=admin

[all:vars]
ansible_python_interpreter=/usr/bin/python3

[root@control ansible]# ansible webservers -m ping
web1 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}
web2 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}

Refer to the exhibit. The administrator wants to run a playbook that installs a package on all webservers. Which command will use the existing configuration and inventory correctly?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.

    },
    "changed": false,
    "ping": "pong"
}

A
ansible-playbook -e 'ansible_python_interpreter=/usr/bin/python3' site.yml
Why wrong: The interpreter is already defined in inventory vars; this is redundant.
B
ansible-playbook site.yml
ansible-playbook reads ansible.cfg automatically, using the defined inventory.
C
ansible webservers -m package -a 'name=httpd state=present'
Why wrong: This is an ad-hoc command, not a playbook.
D
ansible-playbook -i inventory site.yml
Why wrong: While this works, it overrides the inventory defined in ansible.cfg.

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

✓

ansible-playbook site.yml

The ansible.cfg sets inventory=./inventory and roles_path=./roles. The playbook should be run with ansible-playbook, which reads the configuration automatically. The -i flag is not needed because inventory is defined in ansible.cfg.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
ansible-playbook -e 'ansible_python_interpreter=/usr/bin/python3' site.yml
Why it's wrong here
The interpreter is already defined in inventory vars; this is redundant.
✓
ansible-playbook site.yml
Why this is correct
ansible-playbook reads ansible.cfg automatically, using the defined inventory.
Clue confirmation
The clue word "which command" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
ansible webservers -m package -a 'name=httpd state=present'
Why it's wrong here
This is an ad-hoc command, not a playbook.
✗
ansible-playbook -i inventory site.yml
Why it's wrong here
While this works, it overrides the inventory defined in ansible.cfg.

Common exam traps

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Trap categories for this question

Command / output trap
This is an ad-hoc command, not a playbook.

Detailed technical explanation

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

Identify inside and outside interfaces first.
Check whether the scenario needs static NAT, dynamic NAT or PAT.
Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Real-world example

How this comes up in practice

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.

What to study next

Got this wrong? Here's your next step.

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related EX294 NAT questions on configuration and troubleshooting.
