A Python script is designed to automate the retrieval of security events from a SIEM API. The API uses token-based authentication and returns a 429 Too Many Requests status when rate limits are exceeded. The script currently fails when it receives 429. What is the best practice to handle this?

Ignore the 429 and continue with the next request.

Switch to Basic Auth to bypass the rate limit.

Immediately retry the request multiple times in a loop.

Implement exponential backoff and retry the request after a delay.

A Python script receives a JSON response from a network device's API that contains a list of interfaces, each with a 'name' and 'status'. The script needs to filter for interfaces that are 'up' and print their names. Which code snippets correctly accomplish this? (Select all that apply.)

for interface in data['interfaces']: if interface['status'] == 'up': print(interface['name'])

for interface in data['interfaces']: if interface['status'] == 'up': print(interface['name']) else: print('down')

print([interface['name'] for interface in data['interfaces'] if interface['status'] == 'up'])

for interface in data['interfaces']: if interface.get('status') == 'up': print(interface.get('name'))

A Python script using the requests library to interact with a network device's REST API returns a 401 status code. The script uses an API key in the header. What is the most likely cause and the correct next step?

The request is malformed; check the JSON payload syntax.

The API key is invalid or expired; regenerate the API key and update the script.

The server is experiencing an internal error; retry after a delay.

The requested resource does not exist; check the URI path.

A network engineer is writing a Python script to parse an XML response from a NETCONF API. The XML contains multiple 'interface' elements, each with a 'name' attribute and a 'status' child element. The engineer needs to extract the name and status for all interfaces. Which code snippets correctly achieve this? (Select all that apply.)

import xml.etree.ElementTree as ET; root = ET.fromstring(xml); for iface in root.iter('interface'): print(iface.get('name'), iface.find('status').text)

import re; for match in re.finditer(r' .*? (.*?) ', xml): print(match.group(1), match.group(2))

import xml.etree.ElementTree as ET; root = ET.fromstring(xml); for iface in root.findall('.//interface'): print(iface.get('name'), iface.find('status').text)

import xml.etree.ElementTree as ET; root = ET.fromstring(xml); for iface in root.findall('interface'): print(iface.get('name'), iface.find('status').text)

An engineer is writing a Python script to create a new VLAN on a switch using its REST API. The API expects a JSON payload with the VLAN ID and name. Which code snippet correctly sends the request?

requests.put(url, data={'vlan': {'id': 100, 'name': 'Engineering'}})

requests.get(url, json={'vlan': {'id': 100, 'name': 'Engineering'}})

requests.post(url, json={'vlan': {'id': 100, 'name': 'Engineering'}}, headers={'Content-Type':'application/json'})

requests.post(url, data=json.dumps({'vlan': {'id': 100, 'name': 'Engineering'}}))
