Cisco 200-901 Online Questions & Answers

• Question 361:

  What are two advantages of model-driven programmability as compared to traditional network management? (Choose two.)

  A. standardized transport protocol
  B. better performance
  C. better visibility and control
  D. device abstraction
  E. access to more routing features
  C. better visibility and control
  D. device abstraction

• Question 362:

  A network engineer developed an application that performs configuration automation. The engineer used the MVC model for the application design. It has a web interface for users to interact, collect configuration directives for specific devices, and communicate with network devices through REST-based APIs. What is the advantage of the model component in MVC design in this scenario?

  A. It contains data and responds to state queries and updates.
  B. It keeps views and controllers updated during the execution.
  C. It defines main application behavior and contains functions to run.
  D. It renders the data for easy use by the remaining parts of the design.
  A. It contains data and responds to state queries and updates.

  ---

  In the Model-View-Controller (MVC) design pattern: Model: The model component is responsible for managing the data and business logic of the application. It contains the application's data, responds to queries about the state of the data, and updates the data when changes occur. In the context of a configuration automation application for network devices, the model would handle the representation and management of configuration directives for specific devices. It abstracts the underlying data and provides methods to interact with that data.

• Question 363:

  A developer completed the creation of a script using Git. Before delivering it to the customer, the developer wants to be sure about all untracked files, without losing any information. Which command gathers this information?

  A. git clean -n
  B. git rm -f
  C. git clean -r
  D. git rm *
  A. git clean -n

  ---

  The git clean -n command is used to show which files would be removed from the working directory. It displays the untracked files that would be deleted, without actually removing them. This allows the developer to review the list of untracked files before taking any action, ensuring no important files are accidentally deleted.

• Question 364:

  Which Cisco compute management platform is a premises based solution that Automates and Orchestrates Cisco and non-Cisco infrastructure?

  A. UCS Manager
  B. Cisco Integrated Management Controller
  C. UCS Director
  D. Cisco Intersight
  C. UCS Director

• Question 365:

  An engineer creates a script that makes calls to the Cisco Webex API to create a new room and then add users to the room. The engineer runs the script and receives an HTTP response with status code 200. The engineer wants to make an enhancement to the script to send an email to the added users that includes the title and ID of the room. Which part of the HTTP response contains the additional information?

  A. response body
  B. response header
  C. response content-type
  D. response status code
  A. response body

• Question 366:

  A developer has experienced security issues with a previously developed application. The API offered by that application is open and without any constraints. During a recent attack, the application was overloaded with API requests. To address this issue, an API constraint is implemented to protect the application from future attacks or any sudden throttling. Which API constraint must the application developer implement in this situation?

  A. pagination
  B. rate limiting
  C. filtering
  D. payload limiting
  B. rate limiting

  ---

  Rate limiting is a technique used to control the amount of incoming and outgoing traffic to or from a network. It restricts the number of API requests a user can make within a specified time window, protecting the application from being overwhelmed by too many requests at once. Definition and Purpose: Rate limiting sets a threshold for the number of requests a user or system can make in a given timeframe (e.g., 100 requests per minute). Implementation: Developers can implement rate limiting using various strategies such as token buckets or fixed windows. Benefits: This constraint helps prevent abuse, reduces server load, and ensures the application remains available and performant even during high traffic periods or attacks.

• Question 367:

  Refer to the exhibit.

  

  A network engineer must configure new interfaces on a set of devices and is planning to use an Ansible playbook for the task. All devices support SSH and NETCONF protocol, and the interface variables are unique per device. In which directory are the YAML files including variables hosted to automate the task with the netconf_config module?

  A. current working directory
  B. host_vars directory
  C. group_vars directory
  D. home directory
  B. host_vars directory

  ---

  In Ansible, when using the netconf_config module to automate configuration tasks that include unique interface variables for each device, the variables should be defined in individual YAML files within the host_vars directory. This directory contains host-specific variable files named after each host, allowing Ansible to load the appropriate variables for each device during playbook execution. https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html#organizing-host-and-group-variables

• Question 368:

  A developer improves the code repository to clean a bug on the custom network monitoring application. The developer adds the changes to the staging area and then commits on the local branch. Which command pushes commits that are made on a local branch to the remote repository?

  A. push origin master
  B. git push all
  C. push all
  D. git push origin master
  D. git push origin master

  ---

• Question 370:

  Which implementation creates a group of devices on one or more LANs that are configured to communicate as if they were attached to the same wire?

  A. WLAN
  B. VLAN
  C. IPsec
  D. HSRP
  B. VLAN
