JNCIA-DevOps Junos REST API Practice Question
Which statement best describes the primary architectural difference between NETCONF and the Junos REST API?
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
✓
NETCONF is a connection-oriented RPC protocol over SSH, while Junos REST API is a resource-oriented web API over HTTP/HTTPS.
NETCONF is a session-oriented, connection-oriented protocol running over SSH (port 830) using XML-encoded RPCs. The Junos REST API is a stateless (at the HTTP layer) resource-oriented web API running over HTTP/HTTPS (port 3000/3443) supporting JSON and XML.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NETCONF only supports JSON, while REST API only supports XML.
Why it's wrong here
NETCONF natively uses XML, while REST API supports both JSON and XML.
- ✗
There are no architectural differences; REST API is simply an XML parser for NETCONF.
Why it's wrong here
They use completely different transport mechanisms and architectural paradigms.
- ✗
NETCONF is a web-based stateless API, whereas REST API requires a persistent SSH session.
Why it's wrong here
This describes the characteristics in reverse.
- ✓
NETCONF is a connection-oriented RPC protocol over SSH, while Junos REST API is a resource-oriented web API over HTTP/HTTPS.
Why this is correct
NETCONF uses SSH connections and XML RPCs, while REST API uses HTTP/HTTPS resource URIs.
