JNCIA-DevOps NETCONF And XML API Practice Question
An automation script connects to a Junos device using NETCONF over SSH and retrieves the running configuration. The engineer notices that the retrieved XML elements contain attributes like 'operation="inherit"'. What do these attributes represent in the context of Junos XML 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
✓
They describe the configuration hierarchy manipulation state, indicating whether a statement is inherited from apply-groups or explicitly defined.
Junos XML output uses attributes such as 'operation' to indicate how configuration statements relate to inheritance, deletion, or modification within hierarchical structures.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
They indicate the automation user permission level required to modify that specific node.
Why it's wrong here
User permission levels are governed by Junos login classes, not XML operation attributes.
- ✗
They represent transient states of the NETCONF parser buffer indicating stream synchronization status.
Why it's wrong here
NETCONF parser buffers handle transport encoding rather than configuration inheritance semantics.
- ✗
They represent mapping hints for how Junos hierarchical statements map to hierarchical template inheritances during operational state generation.
Why it's wrong here
Inheritance attributes in Junos XML denote how statement properties or apply-groups propagate down the hierarchy.
- ✓
They describe the configuration hierarchy manipulation state, indicating whether a statement is inherited from apply-groups or explicitly defined.
Why this is correct
Junos configuration output uses operations and attributes to display inheritance status, such as values derived from apply-groups.
