JNCIA-DevOps Python And PyEZ Practice Question
You need to retrieve operational data from a Junos device using a PyEZ RPC call that equates to the CLI command 'show system information'. Which Python statement correctly invokes this RPC?
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
✓
dev.rpc.get_system_information()
In PyEZ, CLI commands can be translated to RPC methods by converting dashes to underscores. 'show system information' becomes dev.rpc.get_system_information().
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
dev.execute("show system information")
Why it's wrong here
While CLI commands can be run via shell/execute plugins, the standard RPC method utilizes dev.rpc.
- ✗
dev.get_config(cli="show system information")
Why it's wrong here
get_config retrieves configuration data, not operational system information.
- ✗
dev.rpc.show_system_information()
Why it's wrong here
Junos XML API tags use hyphenated names which map to underscores in the corresponding RPC tag, resulting in get_system_information, not show_system_information.
- ✓
dev.rpc.get_system_information()
Why this is correct
This translates the XML RPC tag <get-system-information> into a Python method.
