350-401 Question #412: Real Exam Question with Answer & Explanation

The correct answer is B: for interface in netconf_data["GigabitEthernet"]: if interface["enabled"] != 'true': print(interface["description"]). Option B is correct because it iterates through all GigabitEthernet interfaces and checks if the 'enabled' field is NOT equal to 'true' (as a string), which effectively filters for disabled interfaces only, then prints their descriptions. In NETCONF/YANG data parsed from XML, boo

Question

Refer to the exhibit. Which Python code snippet prints the descriptions of disabled interfaces only? A. B. C. D.

Options

Afor interface in netconf_data["GigabitEthernet"]: if interface["enabled"] != 'false': print(interface["description"])
Bfor interface in netconf_data["GigabitEthernet"]: if interface["enabled"] != 'true': print(interface["description"])
Cfor interface in netconf_data["GigabitEthernet"]: if interface["disabled"] != 'true': print(interface["description"])
Dfor interface in netconf_data["GigabitEthernet"]: print(interface["enabled"]) print(interface["description"])

Explanation

Option B is correct because it iterates through all GigabitEthernet interfaces and checks if the 'enabled' field is NOT equal to 'true' (as a string), which effectively filters for disabled interfaces only, then prints their descriptions. In NETCONF/YANG data parsed from XML, boolean values are typically represented as strings ('true' or 'false'), so comparing against the string 'true' is the appropriate approach.
