Refer to the exhibit. A network administrator is using a Python script to test a REST API request. The traceback message indicates that there is an error in the URI. What is a possible issue?
import requests
url = “https://sandboxdnac123.cisco.com/dna/intent/api/v1/network-device”
resp = requests.get(url, verify = False)
Traceback message:
….requests.exceptions.ConnectionError:

Refer to the exhibit. A network administrator is using a Python script to send a REST API request. What is the purpose of the line of code resp = requests.get(url, verify = False) ?

url = “https://sandboxdnac123.cisco.com/dna/intent/api/v1/network-device”
resp = requests.get (url, verify = False)

It omits the sending URL in the response.
It skips the URL verification step and tests the resource path.
It bypasses the certificate validation check.

A network engineer is learning about Rest APIs. When executing a particular API, the server responds with curl. How is this information useful?
Curl shows the retrieved information in JSON format.
Curl shows how to access the content displayed in the response body using curl.
Curl shows the information the API returned from the server.
Curl shows the URL used in the API request.
Curl shows how to access the content displayed in the response body using curl.
In which situation would a synchronous API be used?
when a server is not part of the process
when the original API request or data from the request is delayed
when data is being retrieved from a database
when the client is not required to take action
when data is being retrieved from a database
What is REST?
It is a protocol that allows administrators to manage nodes on an IP network.
It is a way to store and interchange data in a structured format.
It is a human readable data structure that is used by applications for storing, transforming, and reading data.
