JNCIA-DevOps Junos Automation Stack And DevOps Concepts Practice Question
In a DevOps pipeline managing Junos devices, an engineer implements 'Infrastructure as Code' (IaC). Which practice best exemplifies this methodology when applied to Junos routing policies?
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
✓
Defining routing policies in Jinja2 templates and YAML data files, committing them to Git, and automatically pushing them via Ansible playbooks.
IaC defines infrastructure in declarative configuration files stored in version control, allowing automated testing and deployment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Writing custom Python scripts that use regex to parse 'show route' outputs on the fly.
Why it's wrong here
Parsing CLI output with regex is screen scraping, which is brittle and not IaC.
- ✓
Defining routing policies in Jinja2 templates and YAML data files, committing them to Git, and automatically pushing them via Ansible playbooks.
Why this is correct
Correct. Using templates, data files, version control, and automation tools embodies IaC.
- ✗
Manually logging into each router via SSH during a maintenance window to type out policy-options statements.
Why it's wrong here
Manual CLI entry is the opposite of Infrastructure as Code.
- ✗
Using dynamic routing protocols like BGP to automatically advertise prefixes without human intervention.
Why it's wrong here
BGP is a control-plane routing protocol, not Infrastructure as Code.
