• Question 572:

  What is a benefit of organizing code into modules?

  A. improves compatibility with the hardware
  B. improves the user interface
  C. easier to work with the code
  D. easy to compile and test
  C. easier to work with the code

  ---

  Explanation Explanation/Reference:Organizing code into modules provides several benefits, one of which is making it easier to work with the code. Breaking code into modular components allows developers to focus on specific functionalities within each module, making it more manageable and easier to understand. This modular approach enhances code organization, readability, and maintainability.

• Question 573:

• Question 574:

  Refer to the exhibit.

  

  A network engineer is creating a Python script to programmatically save network device configurations. Which code snippet must be placed onto the blank in the code?

  A. self.save
  B. {self.headers}
  C. restconf
  D. netconf
  C. restconf

  ---

  The provided Python script is designed to use the RESTCONF protocol to interact with a network device. RESTCONF is a protocol used for accessing data defined in YANG, using RESTful principles. restconf: This is the correct choice to complete the script as it indicates that the RESTCONF protocol is being used to communicate with the device. The relevant line in the script should read: response = requests.post(f'https://{self.hostname}:{self.port}/restconf/operations/ciscoia:save-config/', headers=self.headers, auth=(self.username, self.password), verify=False) References: Cisco RESTCONF Protocol Guide

• Question 575:

• Question 576:

  DRAG DROP

  Drag and drop the code from the bottom onto the box where the code is missing to construct a Python script that calls a REST API request. Not all options are used.

  Select and Place:

  

  

  ---

  Explanation/Reference:

  The Python script provided is designed to make a POST request to a REST API to create a new task in a to-do list application. Here's a step-by-step explanation of the script:

  Import the requests library to handle HTTP requests. Define the task dictionary with summary and description. Use the requests.post method to send a POST request to the specified URL, passing the task data as JSON and setting the appropriate Content-Type header. Check if the response status code is not 201 (which indicates successful creation). If it's not, raise an ApiError with the status code. Print the created task's ID from the JSON response.

  The provided code options are:

  requests: the library used for making HTTP requests. status_code: used to check the HTTP response status. Content-Type: a header specifying the media type of the resource. raise: used to raise an exception if the status code is not as expected.

  return is not used in this context.

  Explanation/Reference:

• Question 580:

  An engineer must investigate the problems on a web application and address them to related teams. The engineer verifies the application reachability from the single public IP address with port and discovers that HTTPS access works to three servers of a network farm with IP 172.16.50.1 .2 and .4, but HTTPS access to the server with IP 172.16.50.3 does not work. Which problem type must be addressed as the cause for the case?

  A. VPN connectivity
  B. NAT
  C. blocked transport port
  D. proxy
  C. blocked transport port

  ---

  The issue described indicates that HTTPS (port 443) access is not working for one specific server (172.16.50.3) in the network farm, while it works for the others. This suggests that the transport port (port 443) might be blocked or filtered for this particular server. Transport Port Blocking: Network firewalls or security groups might block specific ports for certain IP addresses. Server Configuration: The server might not have the necessary configuration to accept HTTPS connections on port 443. Troubleshooting: Verifying firewall rules, security group settings, and server configurations can help identify and resolve the issue.
