EX294 Manage task execution and roles Practice Question

This EX294 practice question tests your understanding of manage task execution and roles. 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.

You need to run an Ansible playbook every hour to update a dynamic inventory file from a CMDB API. The playbook is stored in /opt/ansible/update_inventory.yml. You want to schedule the execution using a cron job on the control node. The control node runs Red Hat Enterprise Linux 9. The playbook uses Ansible Vault to decrypt API credentials, and the vault password is stored in /etc/ansible/.vault_pass. Which cron entry will execute the playbook hourly?

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

✓

0 * * * * /usr/bin/ansible-playbook --vault-password-file /etc/ansible/.vault_pass /opt/ansible/update_inventory.yml

Option A is correct because it specifies the correct cron schedule (0 * * * * for hourly) and uses full paths to ansible-playbook, vault password file, and playbook. Option B uses the wrong schedule (every minute). Option C uses ansible command instead of ansible-playbook. Option D has an incorrect path for the vault password file.

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.

  • ✗

    0 * * * * /usr/bin/ansible-playbook --vault-password-file ~/.vault_pass /opt/ansible/update_inventory.yml

    Why it's wrong here

    The vault password file path is incorrect; it should be /etc/ansible/.vault_pass as given.

  • ✗

    * * * * * /usr/bin/ansible-playbook --vault-password-file /etc/ansible/.vault_pass /opt/ansible/update_inventory.yml

    Why it's wrong here

    This runs every minute, not hourly.

  • ✗

    0 * * * * /usr/bin/ansible --vault-password-file /etc/ansible/.vault_pass /opt/ansible/update_inventory.yml

    Why it's wrong here

    ansible command is for ad-hoc tasks, not for running playbooks; should be ansible-playbook.

  • ✓

    0 * * * * /usr/bin/ansible-playbook --vault-password-file /etc/ansible/.vault_pass /opt/ansible/update_inventory.yml

    Why this is correct

    Correct: Runs hourly with proper vault password file and playbook path.

    Related concept

    Static NAT maps one inside address to one outside address.

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

    ansible command is for ad-hoc tasks, not for running playbooks; should be ansible-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.
