Q: 11

Refer to the exhibit. 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?

Options

Correct Answer:

Explanation

The error log explicitly shows a FileNotFoundError: [Errno 2] No such file or directory: 'bios.json'. This exception occurs during the execution of load_and_parse.py (line 3) because it cannot find the file it is designed to consume. Since the preceding script, gather_and_create.py, is responsible for creating bios.json, its failure to generate the file—or its failure to place it in the working directory expected by the subsequent task—is the root cause. In Ansible, if a previous task fails to produce a required artifact but does not throw a "failed" status itself (e.g., due to silent internal errors), the subsequent task will fail with the error seen in the exhibit.

Why Incorrect

A. ansible.builtin.script Ansible module: The module successfully transferred and initiated the Python script; the failure is due to the Python code's logic/file handling, not the module's execution mechanism.

C. load_and_parse.py Python script: This script is the "victim" of the error. It is functioning correctly by attempting to open a file it expects to exist; it fails only because the file is missing.

D. provision_cpes.yml Ansible playbook: The playbook structure is valid as it successfully invoked the scripts. The failure is a data-dependency issue between the scripts, not a syntax error in the YAML.
