A Python script using PyEZ calls `dev.rpc.get_interface_information()` and stores the result in a variable named `result`. The engineer needs to extract the name of the first interface from the XML response. Which approach correctly accesses this data?

result['interface-information']['physical-interface']['name']

result.xpath('.//physical-interface/name')[0].text

What is the correct way to pass an XML-formatted argument to an RPC in PyEZ?

Use the `xml` parameter of the `rpc()` method

Use the `format` parameter to specify XML

Pass the XML string as the first argument to `rpc()`

Set the `xml` attribute on the Device object

A senior automation engineer is writing a PyEZ script that must run `get-interface-information` on multiple devices. Some devices may not support a specific argument, causing an RPC error. The engineer needs the script to continue processing other devices when an RPC fails, but also log the error details. Which approach best achieves this?

Catch `Exception` and use `pass` to silently ignore the error.

Call `dev.rpc.get_interface_information()` without arguments to avoid the error.

Use `dev.timeout = 10` to increase the RPC timeout and prevent errors.

Wrap the RPC call in a try-except block catching `RpcError`, log `err.rpc_error`, and continue to the next device.

What is the standard naming convention for Junos RPCs?

They use camelCase and end with `-rpc`

They start with `get-` and use hyphens to separate words

They are named after the CLI command with spaces replaced by dots

They start with `show-` and use underscores

Part of the Python and PyEZ domain, which makes up ~28% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~10–17 in this domain), expect 2–3 from this objective — we provide 21 practice questions to prepare you well beyond it.
