JNCIA-DevOps Junos REST API Practice Question
An automation developer is designing a tool that interacts with multiple network vendors, including Juniper Junos. They evaluate using Junos REST API versus NETCONF. Which workflow advantage does the REST API offer over NETCONF in web-centric application environments?
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
✓
REST API leverages standard HTTP/HTTPS transport infrastructure, making it easily traversable through web proxies and adaptable to modern web frameworks using native JSON.
REST APIs natively integrate with standard HTTP load balancers, web proxies, firewalls inspectable by HTTP/HTTPS, and standard web application frameworks without needing specialized SSH tunnel management or XML parser libraries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
REST API leverages standard HTTP/HTTPS transport infrastructure, making it easily traversable through web proxies and adaptable to modern web frameworks using native JSON.
Why this is correct
HTTP/HTTPS transport and native JSON make REST ideal for web-centric integration compared to SSH-based NETCONF.
- ✗
REST API completely replaces the Junos candidate configuration datastore with a real-time database.
Why it's wrong here
The underlying Junos configuration architecture (candidate/running) remains consistent.
- ✗
REST API natively supports XML parsing, whereas NETCONF only supports binary protocols.
Why it's wrong here
NETCONF also uses text-based XML.
- ✗
REST API guarantees atomic multi-device commits across different vendors without controllers.
Why it's wrong here
REST API is device-specific and does not provide multi-vendor atomic transactions natively.
