Cisco 200-901 Online Practice Questions and Exam Preparation

Cisco 200-901 Online Questions & Answers

• Question 281:

  A development team is creating an application used for contactless payments. The application must:

  1.

  Be web-based

  2.

  Capture and process the credit card information for a purchase.

  Which security action must the web application use to gather and process the private customer data?

  A. Enable RATs to monitor the web application remotely.
  B. Disable botnets to eliminate risks.
  C. Disable TLS to increase the connection speed.
  D. Enable the encryption of network traffic.
  D. Enable the encryption of network traffic.

  ---

  For a web-based application that captures and processes credit card information, it is essential to ensure the security of the private customer data. Enabling the encryption of network traffic, typically through TLS (Transport Layer Security), protects sensitive information by encrypting data transmitted between the client and server. This prevents unauthorized access and ensures data integrity and confidentiality during the transaction process. Cisco DevNet Security Best Practices

• Question 282:

  Refer to the exhibit.

  

  An engineer is creating a Dockerfile for an application to run on a container. Application is a web application build on the Python Flask framework. Which port of the Dockerfile provides desired reachability to the application from the outside of the container?

  A. RUN pip3 install Flask
  B. MAINTAINER User One ([email protected])
  C. EXPOSE 80
  D. COPY ./app
  C. EXPOSE 80

• Question 283:

  Refer to the exhibit.

  

  A developer created a Python script by using the Cisco Meraki API. The solution must:

  1.

  Obtain a list of HTTP servers for a network named “net1”.

  2.

  Print the response body if the HTTP status code is 200.

  3.

  Handle the timeout requests as exceptions, and print Timeout Error next to the exception to stdout.

  Which block of code completes the script?

  

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

  ---

  The block of code that correctly completes the script should handle timeout exceptions and print the error, as well as print the response body if the HTTP status code is 200. Option A achieves this: import requests url = 'https://api.meraki.com/api/v0/networks/net1/httpServers' headers = { 'Accept': 'application/json' } response = requests.get(url=url, headers=headers, verify=False, timeout=5) try: response = requests.get(url, headers=headers, verify=False, timeout=5) response.raise_for_status() except requests.Timeout as e: print("Timeout Error: {}".format(e)) if response.status_code == 200: print(response.text) This code makes a GET request to the specified URL, handles the timeout exception by printing a message, and prints the response body if the status code is 200.

• Question 284:

  A developer starts to learn about building applications that use Cisco APIs. The developer needs access to Cisco security products in a development lab to test the first new application that has been built. Which DevNet resource must be used?

  A. DevNet Code Exchange
  B. DevNet Automation Exchange
  C. DevNet Sandbox
  D. DevNet Communities
  C. DevNet Sandbox

  ---

  Cisco DevNet Sandbox provides developers with access to a variety of Cisco technologies in a lab environment. It is an essential resource for developers who want to test and build applications using Cisco APIs and products. DevNet Sandbox: This platform offers pre-configured, ready-to-use environments that allow developers to experiment with Cisco products, including security products, without the need to set up and configure their own infrastructure.

• Question 285:

  Which two details are captured from the subnet mask? (Choose two.)

  A. portion of an IP address that refers to the subnet
  B. default gateway of the host
  C. unique number ID assigned to the host
  D. part of an IP address that refers to the host
  E. network connection of a host or interface
  A. portion of an IP address that refers to the subnet
  D. part of an IP address that refers to the host

  ---

  The subnet mask is used to determine the network and host portions of an IP address. It helps in defining the size of the subnet and the range of IP addresses within that subnet. Subnet Portion: The subnet mask identifies which part of the IP address refers to the network (subnet) portion. Host Portion: The remaining part of the IP address after applying the subnet mask identifies the specific host within the subnet. Options A and D are correct as they capture the details about the subnet and host portions of an IP address. Cisco DevNet Documentation: Understanding Subnetting

• Question 286:

  Refer to the exhibit.

  

  A developer must integrate a bot with an internal communication app. The developer wants to replace the webexbot package with the teamsbot package by using Ansible and prepares a playbook In the first two tasks, the playbook stops the webexbot and verifies that the teamsbot is installed. What is accomplished in the last task of the workflow when the developer runs the Ansible playbook?

  A. stops the webexbot service and uninstals it and retains its configuration files
  B. installs the webexbot and retains the configuration files
  C. uninstalls the webexbot package and removes its configuration files
  D. searches whether the purge package is available in the repository and uninstalls the webexbot package
  C. uninstalls the webexbot package and removes its configuration files

• Question 287:

  What is the function of an IP address in networking?

  A. represents a network connection on specific devices
  B. specifies the type of traffic that is allowed to roam on a network
  C. specifies resource's location and the mechanism to retrieve it
  D. represents the unique ID that is assigned to one host on a network
  D. represents the unique ID that is assigned to one host on a network

• Question 288:

  A developer is working on an existing feature that needs enhancing. The primary production branch for the application is ‘prim4a3b8c6d80374’ and the branch for working on the feature is ‘feat145678909’. The developer needs to create a clone of the single branch used for the feature that only has commits included in the current line of history. Which Git command must be used?

  A. git clone [url] - -feat145678909 - -single-branch
  B. git clone [url] - -branch feat145678909 - -single
  C. git clone [url] - -single-branch feat145678909
  D. git clone [url] - -branch feat145678909 - -single-branch
  D. git clone [url] - -branch feat145678909 - -single-branch

• Question 289:

  The API documentation has this requirement for a REST API request:
