JNCIA-DevOps Python And PyEZ Practice Question
When executing a PyEZ RPC call that returns a large dataset (e.g., massive routing table), how can you handle the output efficiently without exhausting local memory?
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
✓
Using parser generators or iterator arguments supported by specific RPC wrappers
Using generators or streaming options in RPC handling prevents loading massive XML trees entirely into memory.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
etree.iterparse() directly on the raw socket stream
Why it's wrong here
Incorrect. PyEZ abstracts the socket layer, making direct socket iteration unfeasible.
- ✓
Using parser generators or iterator arguments supported by specific RPC wrappers
Why this is correct
Correct. PyEZ allows using iterators or chunked parsing options for large operational datasets.
- ✗
dev.rpc.get_route_information(normalize=True)
Why it's wrong here
Incorrect. Normalization does not handle streaming.
- ✗
dev.stream_rpc()
Why it's wrong here
Incorrect. stream_rpc is not a standard method.
