Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Both protocols leverage the same underlying Junos data models and management infrastructure.
Why this is correct

REST API bypasses all Junos data models and writes directly to kernel memory.
Why it's wrong here
REST API goes through the standard management daemons and data models.

Why it's wrong here
