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
✓
xml.etree.ElementTree
xml.etree.ElementTree is a standard Python library used for parsing and navigating XML data structures. While JSON and YAML are common serialization formats, NETCONF protocol responses natively return XML, which must be parsed before data manipulation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
xml.etree.ElementTree
Why this is correct
Correct. xml.etree.ElementTree provides functions to parse XML strings and files into hierarchical tree structures.
- ✗
pickle
Why it's wrong here
Incorrect. Pickle serializes and deserializes Python object structures into binary bytes, not XML.
- ✗
yaml
Why it's wrong here
Incorrect. The yaml module (PyYAML) processes YAML formatted data.
- ✗
json
Why it's wrong here
Incorrect. The json module is used for encoding and decoding JSON objects, not XML.
