Cisco 200-901 Online Questions & Answers

• Question 151:

  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 BaseG4 encoded concatenation of the username and password. Which action must be taken to return an output of 200?

  A. Change the verify=False setting in the request to verify=True to enable HTTP Basic authentication
  B. Modify the method from LOGIN to GET and supply the username ;password value as JSON payload
  C. Verify that the username and password values imported from the configuration file ate still valid.
  D. Insert an Authorization header with the values username password from the supplied configuration file.
  B. Modify the method from LOGIN to GET and supply the username ;password value as JSON payload

  This seems like a trick question. Simply changing "login" to "get" should fix it. You're still keeping the HTTPBasicAuth header intact while also sending the user/pass in the json payload according to this answer. Sending it in the payload shouldn't do anything since it's a simple GET. The payload will be ignored and the basic auth header will be used.

• Question 152:

  Which solution reduces costs from MPLS, improves application performance, and simplifies operations?

  A. Cisco NSO
  B. Cisco SD-WAN
  C. Cisco ACI
  D. Cisco DNA Center
  B. Cisco SD-WAN

  ---

  Cisco SD-WAN (Software-Defined Wide Area Network) is a solution designed to optimize and secure connectivity across various networks. It provides several advantages including cost reduction from MPLS (Multiprotocol Label Switching), improved application performance by leveraging multiple types of connections (broadband, LTE, etc.), and simplified operations through centralized management. Cost Reduction from MPLS: Cisco SD-WAN allows enterprises to utilize less expensive broadband internet connections alongside MPLS. This hybrid approach reduces dependency on costly MPLS circuits, significantly lowering WAN costs. Improved Application Performance: By using application-aware routing, SDWAN directs traffic across the best available path, ensuring better performance for critical applications. Simplified Operations: Cisco SD-WAN centralizes network management and policy implementation, simplifying network operations and reducing the complexity associated with traditional WANs.

  A. devnet > output.txt
  B. devnet | output.txt
  C. devnet < output.txt
  D. devnet and output.txt
  A. devnet > output.txt

• Question 154:

  A lead engineer is managing the development of a web application with a team of remote developers using Git as the version control system. What is the advantage of a version control system that allows developers to pick code from any part of the project and perform updates on it?

  A. efficient handling of projects
  B. linear development
  C. build automation
  D. nonlinear development
  D. nonlinear development

  ---

  Nonlinear development in a version control system like Git allows developers to work on different parts of the project independently and simultaneously. This approach provides several advantages: Independent Workflows: Developers can work on different features or bug fixes without interfering with each other's work. Parallel Development: Multiple branches enable parallel development, where teams can develop, test, and merge features separately. Efficient Collaboration: Changes can be reviewed, tested, and merged systematically, improving collaboration among remote teams. References: Git and Nonlinear Development: Understanding Git Workflow

• Question 155:

  What is a characteristic of a VLAN?

  A. associated with IP address subnetworks
  B. consist of physically segmented LANs
  C. users access data from different VLANs
  D. associated with MAC address subnetworks
  D. associated with MAC address subnetworks

• Question 156:

• Question 157:

  What is a benefit of using model-driven programmability on Cisco devices?

  A. deeper monitoring
  B. better logging
  C. automated configuration
  D. increased security
  C. automated configuration

• Question 158:

  An engineer must run tests on several Cisco controllers. Due to the nature of the task, the infrastructure must be running at all times and have access to APIs. Which Cisco DevNet source must the engineer use?

  A. DevNet Learning Labs
  B. DevNet Code Exchange
  C. DevNet Sandbox
  D. DevNet API documentation
  C. DevNet Sandbox

  ---

  The Cisco DevNet Sandbox provides a virtual environment where engineers and developers can access and run tests on various Cisco controllers and infrastructure components. This service offers always-on and reservation-based sandboxes that simulate real-world environments. DevNet Sandbox: The Sandbox offers various environments with preconfigured Cisco devices and APIs, allowing engineers to run tests and develop solutions without affecting live systems. Always-On Sandboxes: These environments are always available and can be used without reservation. API Access: The Sandbox environments include access to APIs, enabling comprehensive testing and integration. References: Cisco DevNet Sandbox: DevNet Sandbox

• Question 159:

  Refer to the exhibit.

  

  Which command needs to be placed on the box where the code is missing to output the value of page_jd in the Python 3.7 script?

  

  A. print(items.get('items')[0].get('page_id'))
  B. print(items.get('items').get('page_id'))
  C. print(items['items']['page_id'].keys())
  D. print(items['items']['page_id'])
  A. print(items.get('items')[0].get('page_id'))

• Question 160:

  Refer to the exhibit.

  

  A developer needs to create a webhook to send all Cisco Webex messages to a third-party tool by using the Cisco Webex API The developer must authenticate with the API before any API calls can be made. To automate the procedure, a Python script is used. Which code snippet must be placed onto the blank in the code?

  A. ‘Authentication’: f’Bearer {token}’,
  B. ‘Authentication’: f’Basic {token}’,
  C. ‘Authorization: f’Basic {token}’,
  D. ‘Authorization: f’Bearer {token}’,
  D. ‘Authorization: f’Bearer {token}’,

  Importing Libraries: The script imports the requests and json libraries necessary for making HTTP requests and handling JSON data. URLs Definition: The url1 variable holds the Webex API endpoint for creating webhooks, and url2 is the target URL where Webex will send the messages. Token Handling: The token variable contains the OAuth2 token required for authentication with the Webex API. Setting Headers: The headers dictionary includes the Content-Type set to application/json and the correct Authorization header that uses the Bearer token. Payload Preparation: The payload dictionary contains the necessary information to create the webhook, including its name, target URL, resource type, and event. Making the Request: The requests.request method sends a POST request to the Webex API endpoint with the specified headers and payload. Printing the Response: The response from the Webex API is printed out, encoded in 'utf-8'. uk.co.certification.simulator.questionpool.PList@18b1dc30 Reference:Cisco Webex API Authentication Cisco Webex API Guide By correctly setting the Authorization header to include the Bearer token, the developer ensures that the script can authenticate and interact with the Webex API as required.
