Cisco 200-901 Online Questions & Answers

• Question 321:

  Which action do webhooks enable an application to perform?

  A. Increase the request rate limit.
  B. Populate the application with restricted data.
  C. Receive real-time data.
  D. Implement a push model.
  C. Receive real-time data.

  ---

  Simplifying the wording: Webhook enables the app to ( push or receive real time) . The clients Webhooks enable applications to receive real-time data by providing a mechanism for one application to send data to another as soon as an event happens. This is done through HTTP callbacks, where an event in the source system triggers an HTTP POST request to a predefined URL in the destination system. This allows the destination system to process the data immediately, ensuring real-time updates. Reference: Cisco DevNet Associate documentation on webhooks and real-time data integration.

• Question 322:

  Which response status code is used by a RESTful interface to indicate successful execution of a request?

  A. 200
  B. 404
  C. 405
  D. 500
  A. 200

• Question 323:

  Which type of OWASP threat forges a malicious HTTP request into an application?

  A. Clickjacking
  B. SQL Injection
  C. XSS
  D. CSRF
  D. CSRF

  ---

  Cross-Site Request Forgery (CSRF) is an OWASP threat that involves the forging of malicious HTTP requests into an application. In a CSRF attack, an attacker tricks a victim's browser into making a request on behalf of the victim to a target application where the victim is authenticated. This can lead to unauthorized actions being performed on the target application without the victim's consent. References: Cisco DevNet Associate Certification Guide OWASP CSRF Prevention Cheat Sheet

• Question 324:

  Refer to the exhibit.

  

  An engineer must configure a load balancer server. The engineer prepares a script to automate workflow by using Bash. The script install the nginx package, moves to the /optAtginx directory, and reads the sites M We (or further processing Based on the script workflow, which process is being automated within the loop by using the information mi sites txt?

  A. creating a new Me Based on template .conf in the /etc/ngin/sites_enabled directory for each lie in the sites txt file. and then changing the file execution permission.
  B. creating a Me per each the in sites txt with the information in template conf. creating a link for the previously created file. and then changing the ownership of the created files
  C. using the content of the file to create the template conf file. creating a Iink from the created file to the /etc/nginx/files.enabled. and then changing the file execution permissions.
  D. using the information in the file to create a set of empty files in the /etchginx/sites_enabled directory and then assigning the owner of the file.
  B. creating a Me per each the in sites txt with the information in template conf. creating a link for the previously created file. and then changing the ownership of the created files

• Question 325:

  A company requires a new platform to store large volumes of log data that is generated in their assembly plant. The platform must be scalable, so the underlying technology must provide a path for fast deployment of new nodes for data and indexing? The data contains sensitive information, so specialist encryption tools must be used to secure the data. Which application deployment model meets the requirements?

  A. edge
  B. private cloud
  C. public cloud
  D. hybrid cloud
  D. hybrid cloud

  ---

  A hybrid cloud combines the benefits of both a private cloud, which offers the ability to store sensitive data in a secure, dedicated environment, and a public cloud, which offers the ability to scale quickly and easily by deploying new nodes as needed. With a hybrid cloud deployment, you could use specialist encryption tools to secure the sensitive data in the private cloud, and then take advantage of the scalability and flexibility of the public cloud to handle the large volumes of log data. https://www.simform.com/blog/cloud-deployment-models/

• Question 326:

  Refer to the exhibit.

  

  Which code snippet represents the sequence.

  

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

  ---

  Refer to the exhibit which shows a sequence diagram illustrating a client- server interaction. The correct sequence of steps that match the code snippet is as follows: Step 1: POST /events - The client posts an event to the server. Step 2: GET /messages/ - The client retrieves the message details from the server using the message ID. Step 3: Response /messages/ - The server responds with the message details. Step 4: GET /team-memberships?teamId= - The client retrieves team membership details using the team ID. Step 5: POST /message - The client posts a message. Step 6: Response /message - The server responds with the message confirmation. The correct code snippet represents the sequence diagram correctly: @flask_app.route('/events', methods=['POST']) def webex_teams_webhook_events(): json_data = request.json['data'] response = requests.get(MESSAGE_URL + json_data['id'], headers=headers) if response.json()['text'] == 'Alert': response = requests.get(TEAM_MEMBERSHIPS_URL, headers=headers, params=params) for info in response.json()['items']: data = {'personId': info['personId'], 'text': 'Alert'}

• Question 327:

  Refer to the exhibit.

  

  Which infrastructure automation method is shown?

  A. CI/CD pipeline
  B. Lean
  C. Agile
  D. Waterfall
  A. CI/CD pipeline

• Question 328:

  Which status code is used by a REST API to indicate that the submitted payload is incorrect?

  A. 400
  B. 403
  C. 405
  D. 429
  A. 400

  A. docker run -t -i myWebApp -p 8080:80 bash
  B. docker cmd -t -i myWebApp -d 80:808 bash
  C. docker start -t -i apche2 -p 8080:80 bash
