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 XML CDATA blocks embedded within JSON keys.
Why it's wrong here
XML CDATA is not used inside JSON payloads.
- ✗
As numerical indexed keys (e.g., 'route-0', 'route-1').
Why it's wrong here
Junos REST JSON structures use arrays rather than manual numerical key indexing.
- ✓
As JSON arrays containing objects for each list entry.
Why this is correct
Multi-instance list entries map to JSON arrays.
- ✗
As a single concatenated string separated by semicolons.
Why it's wrong here
JSON uses arrays for multi-instance lists, not semicolon strings.
