   An engineer is writing a JSNAPy test to verify that all interfaces configured with `family inet` also have an `mtu` of exactly 1500. The test file uses `get-interface-information` RPC. The test fails on some interfaces that do have `mtu 1500`. What is the most likely cause?

   • AThe test is using `contains` instead of `is_equal`, and the `mtu` value appears in a different context.
   • BThe device is running an older Junos version that does not support the `get-interface-information` RPC.
   • CThe XPath in the test is not specific enough and is matching the wrong part of the XML tree.
   • DThe `mtu` value is returned as a string, and the test expects an integer.

   A service provider manages hundreds of CPE devices. They want to use JSNAPy to detect configuration drift. The plan is to capture a baseline snapshot of each device and then periodically compare. However, the CPE devices have varying hardware models, and the configuration differs slightly per model. How should the snapshots be managed to avoid false positives?

   • ADisable the `--snapcheck` operation and use manual review instead.
   • BCapture a single baseline snapshot from one device and use it for all devices.
   • CCapture one baseline snapshot per device model and use it for all devices of that model.
   • DUse `is_equal` tests instead of `contains` to allow for model-specific differences.

   • ADuring the decommissioning process to erase device configurations
   • BDuring the initial device provisioning and zero-touch provisioning (ZTP)

   • DAfter a configuration change is applied, to validate the device is in the expected state
