JNCIA-DevOps Data Serialization Practice Question
You are writing a Python script that converts a Junos operational state output from XML (via NETCONF) into JSON. The XML structure contains sibling elements with the same tag name. When converted naively, how do standard XML-to-JSON conversion libraries (like xmltodict) typically represent these repeated sibling elements in the resulting JSON dictionary?
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
✓
As a JSON array containing multiple objects.
Conversion libraries like xmltodict represent repeated sibling XML elements as a JSON array (list) to preserve all instances under a single key.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
By appending numeric indexes to every key name automatically.
Why it's wrong here
Incorrect. Indexes are not appended to key names by default.
- ✓
As a JSON array containing multiple objects.
Why this is correct
Correct. Sibling elements with identical tags are aggregated into a JSON array.
- ✗
By raising a DuplicateElementException.
Why it's wrong here
Incorrect. Duplicate tags are handled by list conversion, not exceptions.
- ✗
By overwriting previous elements so only the last element is retained.
Why it's wrong here
Incorrect. Libraries like xmltodict avoid data loss by creating lists for repeated tags.
