At ValidExamDumps, we consistently monitor updates to the Cisco 200-901 exam questions by Cisco. Whenever our team identifies changes in the exam questions, objectives, focus areas or requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these up to date and 100% exam domain coverage questions, our customers can successfully pass the Cisco Automating Networks Using Cisco Platforms exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Cisco in their 200-901 exam. These outdated questions lead to customers failing their Cisco Automating Networks Using Cisco Platforms exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions. Our main priority is your success in the Cisco 200-901 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.

The definition of the YANG module and a RESTCONF query sent to a Cisco IOc XE device is shown. Which statement is correct if the RESTCONF interface responds with a 204 status code?
What does a developer import in a script to parse a file from XML to Python?
To parse XML data in Python, a developer typically imports a library that provides the necessary functions and methods for XML parsing.
Libraries for XML Parsing: Python has several libraries for parsing XML, such as xml.etree.ElementTree, lxml, and minidom.
Functionality: These libraries offer functions and methods to read, manipulate, and extract data from XML files.
Example:
import xml.etree.ElementTree as ET
tree = ET.parse('file.xml')
root = tree.getroot()
Refer to the exhibit.
Which command, including arguments, is executed when the container starts?
The Dockerfile shown in the exhibit sets up an NGINX container with a delay before starting the NGINX service. It uses the ENTRYPOINT and CMD directives to define the commands that should be executed when the container starts.
ARG and ENV: These lines define and set an argument and environment variable for the delay.
ENTRYPOINT: Specifies the executable to run, in this case, /bin/sh.
CMD: Provides additional arguments to the ENTRYPOINT, which are -c and the command string to execute.
The combined command that will be executed is: /bin/sh -c '/bin/sleep 30 && nginx -g 'daemon off;''
Docker Documentation: ENTRYPOINT

What does the python function do?
The Python function shown in the exhibit performs the following operations:
It defines a function get_result().
Inside the function, it sets the url variable to the Cisco DNA Center (DNAC) API endpoint for authentication tokens.
It makes a POST request to the specified URL with HTTP Basic Authentication using the credentials DNAC_USER and DNAC_PASSWORD.
The response from the POST request is expected to be in JSON format.
It extracts the value associated with the key 'Token' from the JSON response.
Finally, it returns this token.
This function's purpose is to obtain and return an authorization token from the Cisco DNA Center API, which can be used for subsequent API requests.
When a Cisco IOS XE networking device is configured using RESTCONF, what is the default data-encoding method?
When configuring a Cisco IOS XE device using RESTCONF, the default data-encoding method is XML. RESTCONF is a protocol used to access configuration data and operational data using a REST-like API, and it uses XML as the default encoding method for data exchange.
XML: Used as the default encoding method for RESTCONF.
x-form-encoding: Not used by RESTCONF.
YANG: A data modeling language used to model configuration and state data manipulated by NETCONF and RESTCONF, but not an encoding method.
YAML: Not used by RESTCONF.
