Cisco 350-401 Dumps Questions Answers

 The Python script in the exhibit is using the requests library to make HTTP requests to a specific URL and retrieve JSON data. The json.loads() method is used to parse the JSON data from the HTTP response. The script retrieves version information and count from one endpoint, then iteratively retrieves IP addresses based on the count, appending them to a list named ‘bp’. Therefore, it reads JSON data into a formatted list. References: I need to search for specific references as I don’t have direct access to Implementing and Operating Cisco Service Provider Network Core Technologies content.

The correct Python code to display the value of the ‘role’ key, based on the router’s API output in JSON format, is Option B. In this option, json_data is assigned the JSON content from response.json(). Then it prints the value associated with the ‘role’ key which is nested inside ‘family’, which in turn is nested inside ‘response’. The syntax json_data['response']['family']['role'] is used to access nested dictionaries in Python. References: For an exact reference, please consult the Implementing and Operating Cisco Service Provider Network Core Technologies source documents or study guide.

 The command ip http secure-server is used to enable the HTTPS server on a Cisco device, which is necessary for RESTCONF to operate securely. RESTCONF is an HTTP-based protocol that provides a programmatic interface for accessing data defined in YANG, using the datastore concepts defined in NETCONF. Enabling the HTTPS server ensures that RESTCONF can be used over a secure connection, which is a best practice for network security. References: Cisco Programmability Configuration Guide, RESTCONF Protocol Video.
