An engineer creates an application that leverages the Ansible framework to provision CPE endpoints that have configuration changes.
The application contains an Ansible playbook named provision_cpes.yml that uses the ansible.builtin.script Ansible module to execute these two Python scripts:
• gather and_create.py. which creates a JSON file named bios.json that contains the CPE models and their respective IOS file information
• load and parse.py. which loads the file data and parses it for later consumption
After several successful runs, the application fails. During a review of the Ansible execution logs, the engineer discovers an error output that indicates that one of the stages failed.
What is the cause of this issue?
- A . ansible builtm script Ansible module
- B . gather and create.py Python script
- C . load_and_parse.py Python script
- D . provision cpes.yml Ansibte playbook
