  Explanation/Reference:

• Question 462:

  An automation script fails to connect to an internal server exactly 1 out of 2 times it is executed. This behavior is seen from different clients. Which networking device must be at fault?

  A. load balancer
  B. laptop on which the script is running
  C. switch
  D. router
  A. load balancer

• Question 463:

  Refer to the exhibit. A developer got this output during the development of an application. Which action produces this output?

  

  A. execution of a Python script with numpy library
  B. enhancement to Python numpy library
  C. upload of a script to a git repository
  D. file comparison within the unified diff format
  D. file comparison within the unified diff format

• Question 464:

  A company is looking for a cloud deployment which will only use the on-premise infrastructure, is user self- service, and is easy to scale. Which cloud solution should be selected for these requirements?

  A. multi
  B. private
  C. hybrid
  D. public
  B. private

  ---

  Explanation Explanation/Reference:The only one that uses only onprem is Private

• Question 465:

  A company deploys an application via containers in its local data center. As soon as the application goes into production, it starts to crash at specific hours of the day. After investigation, it is concluded that the crashes are due to too many users accessing the application simultaneously. The spikes must be addressed and allow for future growth without discarding the investment already made. Which deployment model must be used?

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

  ---

  A hybrid cloud deployment model is the best choice for addressing the issue of application crashes due to spikes in user access while allowing for future growth and preserving existing investments. Hybrid cloud integrates on-premises data centers (private cloud) with public cloud services, providing scalability and flexibility. This model allows the company to handle peak loads by offloading traffic to the public cloud while maintaining critical applications and data in the private cloud. https://www.networkworld.com/article/3599213/what-are-data-centers-how-they-work-and-how-they-are-changing-in-size-and-scope.html

• Question 466:

  Which type of threat occurs when an attacker can send hostile data to an interpreter within an application?

  A. sensitive data exposure
  B. broken authentication
  C. cross-site scripting
  D. injection
  D. injection

• Question 467:

  Which network constraint causes the performance of the application to decrease as the number of users accessing the application increases?

  A. latency
  B. loss
  C. bandwidth
  D. jitter
  C. bandwidth

  ---

  Bandwidth is the network constraint that affects the performance of an application as the number of users accessing the application increases. Bandwidth refers to the maximum rate of data transfer across a network path. If the bandwidth is insufficient to handle the increased traffic, the application performance will degrade, leading to slower response times and potential timeouts.

  A. management plane
  B. data plane
  C. authentication plane
  D. control plane
  D. control plane

• Question 470:

  What is a characteristic of test-driven development?

  A. It enables code refactoring.
  B. User tests are created after deployment.
  C. Infrastructure testing is done at every stage.
  D. Large updates are applied infrequently.
  A. It enables code refactoring.

  Test-Driven Development (TDD) is a software development approach where tests are written before writing the actual code. TDD enables and encourages code refactoring because it ensures that tests are already in place to verify the correctness of the code after changes. Red-Green-Refactor Cycle: TDD follows a cycle of writing a test (Red), writing code to pass the test (Green), and then refactoring the code while ensuring the test still passes (Refactor). Refactoring Support: Because tests are written first, developers can confidently refactor code knowing that any changes that break functionality will be caught by the existing tests.
