JNCIA-DevOps Junos REST API Practice Question
Which THREE architectural features distinguish the Junos REST API from traditional CLI screen-scraping (CLI automation via expect scripts)? (Choose three)
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
✓
Resource-based URI routing that maps directly to configuration and operational models.
REST API provides structured data formats (JSON/XML), deterministic API contracts with HTTP status codes, and programmatic resource addressing, whereas screen-scraping relies on fragile text parsing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Resource-based URI routing that maps directly to configuration and operational models.
Why this is correct
REST API uses predictable URIs for resources rather than CLI prompt navigation.
- ✗
Strict enforcement of synchronous modal CLI configuration blocks.
Why it's wrong here
CLI modal configuration is specific to the human CLI interface, not REST APIs.
- ✓
Native support for structured data representations like JSON and XML.
Why this is correct
REST API delivers structured data natively, eliminating regex text parsing.
- ✗
Requirement for VT100 terminal emulation buffers.
Why it's wrong here
VT100 emulation is for CLI terminal sessions, not REST APIs.
- ✓
Use of standardized HTTP status codes for programmatic error handling.
Why this is correct
HTTP status codes provide clear, programmatic success and error indicators.
