A network device API returns configuration data in XML format. The engineer needs to extract the value of the 'hostname' element from the XML response. Which Python approach is most appropriate?

Use string manipulation to search for the hostname tag

Use the yaml library to parse the XML

Use the xml.etree.ElementTree library to parse the XML and find the element

Use the json library to parse the XML

A Python script is being written to interact with a network device's REST API that uses Basic Authentication. The script must send credentials securely. Which approach should the engineer use?

Include the credentials in the URL, e.g., https://user:pass@device/api

Use the requests library's auth parameter with a tuple of username and password

Send the credentials in the request body as JSON

Use a custom header like X-Credentials

An engineer is writing a Python script to send a JSON payload to a network device API to configure a VLAN. The payload must include a nested object for the VLAN interface. Which Python data structure correctly represents this JSON payload?

payload = {'vlan': [{'id': 10, 'name': 'Users', 'interface': {'ip': '192.168.10.1'}}]}

payload = {'vlan': {'id': 10, 'name': 'Users', 'interface': {'ip': '192.168.10.1'}}}

payload = {'vlan': 'id=10,name=Users,interface=ip=192.168.10.1'}

payload = {'vlan': {'id': 10, 'name': 'Users', 'interface': '192.168.10.1'}}

A network device API expects an XML payload to create a new access-list entry. The XML must include a namespace. Which Python code correctly constructs the XML payload with a namespace?

Use string concatenation to build the XML with the namespace

Use xml.etree.ElementTree and register the namespace with ET.register_namespace()

Use the json library to generate XML

Use the yaml library to generate XML
