• Question 143:

  Refer to the exhibit.

  

  A network engineer must change the configuration on devices daily. The Python script must collect CLI arguments from the user, organize data according to the Cisco-IOS-XE-native YANG model, and utilize Cisco REST APIs to make the configuration. Which workflow is being automated by the Python script?

  What is the impact on an application from having a large distance between a client device and a host server?

  A. latency
  B. increased bandwidth
  C. loss of connectivity D. jitter
  A. latency

  ---

  Latency refers to the delay between a client request and a server response. A large distance between a client device and a host server increases the latency due to the time it takes for data to travel over the network. Latency: The time delay experienced in a system, particularly in networking, where it refers to the time taken for data to travel from the source to the destination. Impact: High latency can result in slow response times, negatively impacting the performance of applications, especially those requiring real-time interactions.

  What are two advantages of applying the MVC design pattern to the development of the solution? (Choose two.)

  A. to enable multiple views of the same data to be presented to different groups of users
  B. to provide separation between the view and the model by ensuring that all logic is separated out into the controller
  C. to ensure data consistency, which requires that changes to the view are also made to the model
  D. to ensure that only one instance of the data model can be created
  E. to provide only a single view of the data to ensure consistency
