• Question 22:

  Refer to the exhibit.

  

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

  A. Update the API URL. which matched the API endpoint for device list.
  B. Send the request to another network in case there are reachability Issues.
  C. Send the Authentication header In the request with a valid configuration.
  D. Update the credentials that are already supplied and retry the request
  C. Send the Authentication header In the request with a valid configuration.

  Explanation Explanation/Reference: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.

• Question 23:

  What is an advantage of the Agile software development method as compared to Waterfall?

  A. In Agile the development teams deliver the whole project at once, and in Waterfall the project is delivered in phases.
  B. In Agile the customer involvement is limited to the requirement collection phase, and in Waterfall the customer is involved in all development phases.
  C. In Agile every aspect of development is continually revisited, and in Waterfall the revision takes place in another project.
  D. In Agile each development team works independently, and in Waterfall the development team collaborate.
  C. In Agile every aspect of development is continually revisited, and in Waterfall the revision takes place in another project.
