                                    Cisco DevNet Associate Exam Sample Questions (Q282-Q287):

                                    NEW QUESTION # 282
                                    A team of developers is responsible for a network orchestration application in the company. The responsibilities also include:
                                    - developing and improving the application in a continuous manner
                                    - deployment of the application and management of CI/CD frameworks
                                    - monitoring the usage and problems and managing the performance
                                    improvements
                                    Which principle best describes this DevOps practice?

                                    Answer: C


                                    NEW QUESTION # 283
                                    What are two benefits of implementing common data structures when working with APIs in remote systems? (Choose two.)

                                    Answer: B,C

                                    Explanation:
                                    Implementing common data structures when working with APIs in remote systems has multiple benefits:
                                    Enforces standardized data structures: This ensures consistency and interoperability across different systems and APIs, making it easier to integrate and communicate between various components.
                                    Leverages code that is easily managed and reused: Standardized data structures lead to more maintainable and reusable code. Developers can build upon existing frameworks and libraries without having to rewrite data handling logic for each new API.

                                    NEW QUESTION # 284
                                    Which two HTTP code series relate to errors? (Choose two.

                                    Answer: C,E

                                    Explanation:
                                    HTTP status codes are divided into five classes:
                                    1xx (Informational): Request received, continuing process
                                    2xx (Success): The action was successfully received, understood, and accepted
                                    3xx (Redirection): Further action must be taken to complete the request
                                    4xx (Client Error): The request contains bad syntax or cannot be fulfilled
                                    5xx (Server Error): The server failed to fulfill an apparently valid request Thus, the series that relate to errors are:
                                    400 series (Client Error)
                                    500 series (Server Error)

                                    NEW QUESTION # 285
                                    What is the purpose of the Cisco VIRL software tool?

                                    Answer: A

                                    Explanation:
                                    Cisco CML/VIRL is a powerful network simulation platform that is meant to be a flexible, all-in-one virtual networking lab. With Cisco CML/VIRL and virtual instances of network operating systems from Cisco, it is possible to build entire network simulations.


                                    NEW QUESTION # 286
                                    What are two benefits of using classes over functions when writing applications? (Choose two.)

                                    Answer: C,E

                                    Explanation:
                                    When writing applications, using classes over functions offers several benefits, including improved readability and better code organization. Here are the detailed explanations for these two benefits:
                                    Improved Readability (A):
                                    Classes allow for encapsulation, which means grouping related data and functions (methods) together. This makes the code more readable and easier to understand because the related functionality is bundled in a single, self-contained unit.
                                    Object-Oriented Programming (OOP) principles such as inheritance and polymorphism further enhance readability by reducing code duplication and promoting code reuse.
                                    Code Organization (E):
                                    Classes provide a clear structure for organizing code. They help in logically grouping related functionalities, which enhances the modularity of the application. This organization makes it easier to manage and maintain the codebase, especially as the application grows in complexity.
                                    By using classes, developers can create blueprints for objects, making it easier to implement and manage complex systems with multiple interconnected components.
                                    Classes are fundamental to Object-Oriented Programming, which is a paradigm that many modern programming languages, including Python and Java, are built around. While functions are essential for specific tasks and operations, classes provide a higher level of abstraction and organization.
