Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To compile YAML files into Junos microcode for the Packet Forwarding Engine.
Why it's wrong here
Junos does not compile user data files into PFE microcode.
- ✗
To automatically execute unit tests against live BGP peering sessions.
Why it's wrong here
Linters check static file syntax and style, not live BGP sessions.
- ✓
To detect syntax errors, indentation issues, and style violations in template and data files before deployment.
Why this is correct
Correct. Linters validate static code and markup syntax prior to runtime execution.
- ✗
To encrypt sensitive passwords stored within plaintext configuration files.
Why it's wrong here
Encryption is handled by tools like Ansible Vault or SOPS, not standard linters.
