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
✓
As nested JSON objects reflecting the hierarchical tree structure of the CLI configuration.
Junos configuration hierarchies are translated into nested JSON objects where each container level corresponds to a JSON key whose value is an object or an array of objects.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
As comma-separated string lists inside a single root array.
Why it's wrong here
Configuration trees require structured object nesting, not flat comma-separated lists.
- ✗
As flat key-value pairs separated by dots (e.g., 'system.host-name').
Why it's wrong here
Junos REST JSON representations preserve hierarchical nesting rather than dot-separated flattening.
- ✓
As nested JSON objects reflecting the hierarchical tree structure of the CLI configuration.
Why this is correct
Hierarchical container structures map directly to nested JSON objects.
- ✗
As binary encoded ASN.1 objects.
Why it's wrong here
Junos REST API uses textual JSON, not binary ASN.1 encoding.
