2. Question 512 · 530 in bank

   

   Refer to the exhibit. A network engineer must manage the network devices. The engineer prepares a Python script to authenticate to the Cisco DNA Center API and request a device list. The device request fails and returns error code 401. Which action solves the problem?

   • AUpdate the credentials that are already supplied and retry the request.
   • BSend the request to another network in case there are reachability issues.
   • CSend the Authentication header in the request with a valid configuration.
   • DUpdate the API URL, which matched the API endpoint for device list.

   Show answer

   Answer: C

   Explanation

   In the provided code, the authentication token is being requested and stored in the "token" variable, but it is not being included in the subsequent request for the device list. To solve the problem, the authentication token should be included in the request header as an "Authorization" field. For example: headers = {'Content-Type': 'application/json', 'Authorization': f'Bearer {token}'} This will include the necessary credentials in the request and allow it to be authenticated by the server.

   Refer to the exhibit. A developer creates a Python script that queries Cisco Webex. When the script is executed, a 401 code is returned. After troubleshooting, the developer discovers that the service is missing privileges. Which change to the header in line 4 of the script results in the code 200?

   • Aheader = {ג€Authenticationג€: ג€Bearer YOUR_TOKENג€}
   • Bheader = {ג€Authentication Bearerג€ : ג€YOUR_TOKENג€
   • Cheader = {ג€Authorization Bearerג€ : ג€YOUR_TOKENג€}
   • Dheader = {ג€Authorizationג€ : ג€Bearer YOUR_TOKENג€}

   Show answer

   Answer: D

   Explanation

   Pro tip on these questions that have jacked-up formatting with the ג€ special chars. Go to DevTools (Press F12 in Chrome), go to the Console tab, and run this: document.body.innerHTML = document.body.innerHTML.replace(/ג€/g, "'") That will replace all of the junk chars on your current page with the proper single quotes. Sad that we pay hundreds for this site, and they can't render text properly.

9. Question 519 · 530 in bank

   

   Refer to the exhibit. The script returns an output of 401. To use the supplied URL, an HTTP GET request must be sent with an Authorization header. The header value is a base64 encoded concatenation of the username and password. Which action must be taken to return an output of 200?

   • AChange the verify=False setting in the request to verify=True to enable HTTP Basic authentication.
   • BVerify that the username and password values imported from the configuration file are still valid.
   • CInsert an Authorization header with the values username:password from the supplied configuration file.
   • DModify the method from LOGIN to GET and supply the username:password value as JSON payload.

   Show answer

   Answer: D

   Explanation

   The question is crazy and very bad worded. If requests.login doesn''t exist, there should not be present any status code of 401, because the python script will not send anything, because it doesn't understand the syntax. Secondly, even with a get message there is no sense that the username:passoword should be json payload. It makes sense to use basic auth in this form or to use basic auth header in json format. From my point of view this question is wrong
