• Question 535:

  What is impacted by the network bandwidth on an application?

  A. time taken for a data packet to travel between two endpoints
  B. number of data packets dropped during transmission
  C. consistency in the arrival of data packets between two endpoints
  D. rate of data transferred between two endpoints
  D. rate of data transferred between two endpoints

  ---

  Network bandwidth directly impacts the rate of data transferred between two endpoints. Bandwidth is the capacity of a network to transmit data, and it is typically measured in bits per second (bps), kilobits per second (kbps), or megabits per second (Mbps). The higher the bandwidth, the more data can be transferred in a given amount of time.

• Question 536:

  DRAG DROP

  Refer to the exhibit.

• Question 539:

  A developer creates an application that must provide an encrypted connection or API keys. The keys will be used to communicate with a REST API. Which command must be used for the secure connection?

  A. curl -X PUSH `http://username.app.com/endpoint/?api_key=12345abcdef'
  B. curl -v `ftp://username.app.com/endpoint/?api_key=12345abcdef'
  C. curl -X GET `https://username.app.com/endpoint/?api_key=12345abcdef'
  D. curl -X GET `http://username.app.com/endpoint/?api_key=12345abcdef'
  C. curl -X GET `https://username.app.com/endpoint/?api_key=12345abcdef'

  ---

  To provide an encrypted connection when using API keys to communicate with a REST API, the connection must use HTTPS. The curl command with the -X GET option and an HTTPS URL ensures that the communication is encrypted, protecting the API key and data in transit. Cisco DevNet Secure API Communication

• Question 540:

  A developer has created a three-tier web application for network device control and management. The application consists of multiple objects assigned for different functionalities. The architecture of the application is based on the Observer pattern. Which advantage does this pattern provide for the application design and architecture?

  A. Independent observers are updated automatically.
  B. It updates the state of dependent subjects directly.
  C. One observer can query the state of other subjects
  D. It decouples the subjects from the observers.
  D. It decouples the subjects from the observers.

  ---

  The Observer pattern is designed to establish a one-to-many dependency between objects so that when one object (the subject) changes its state, all its dependents (observers) are notified and updated automatically. The key advantage of the Observer pattern is decoupling, and this is achieved by ensuring that subjects (the objects being observed) do not need to know anything about their observers.
