Cybage Interview Questions and Answers

Dependency Injection is a design pattern where components are given their dependencies rather than creating them internally.

• Allows for easier testing by mocking dependencies

• Promotes loose coupling between components

• Improves code reusability and maintainability

Routings in MVC define how the application responds to client requests.

• Routings map URLs to controller actions in MVC framework

• Routes are defined in RouteConfig.cs file in ASP.NET MVC

• Routes can include parameters and constraints

• Example: routes.MapRoute('Default', '{controller}/{action}/{id}', new { controller = 'Home', action = 'Index', id = UrlParameter.Optional })

Garbage collection is an automatic memory management process used in programming languages to reclaim memory occupied by objects that are no longer in use.

• Garbage collection automatically identifies and deletes objects in memory that are no longer needed by the program.

• It helps prevent memory leaks and improves the efficiency of memory usage.

• Examples of programming languages that use garbage collection include Java, C#...read more

Secure WEB API in .NET by using authentication, authorization, HTTPS, and input validation.

• Use authentication mechanisms like JWT tokens or OAuth for secure access.

• Implement authorization to control which users have access to specific resources.

• Enable HTTPS to encrypt data transmitted between client and server.

• Implement input validation to prevent injection attacks like SQL injection or cross-site scripting.

Stored procedures are precompiled SQL queries stored in the database, while functions are reusable blocks of code that return a value.

• Stored procedures are used for performing specific tasks or operations in the database.

• Functions are used to encapsulate logic and can be called from within SQL queries or other functions.

• Stored procedures can have input and output parameters, while functions always return a value.

• Stored...read more

OOP concepts are fundamental principles that guide object-oriented programming, enhancing code organization and reusability.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism where a new class derives properties and behavior from an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to present the same interf...read more

Inbound calls are received by the company from customers, while outbound calls are made by the company to customers.

• Inbound calls are initiated by customers seeking assistance or information.

• Outbound calls are initiated by the company for sales, marketing, or follow-up purposes.

• Inbound calls are typically toll-free for customers, while outbound calls may incur charges.

• Examples: Inbound call - Customer calling a technic...read more

Serverless refers to a cloud computing model where the cloud provider manages the infrastructure and automatically allocates resources as needed.

• Serverless computing allows developers to focus on writing code without worrying about managing servers or infrastructure.

• Resources are dynamically allocated and scaled based on demand, leading to cost efficiency.

• Examples of serverless platforms include AWS Lambda, Azure Funct...read more

Azure Functions is a serverless compute service that allows you to run event-triggered code without managing infrastructure.

• Azure Functions allows you to write small pieces of code that run in response to events.

• It supports multiple programming languages like C#, JavaScript, Python, etc.

• Functions can be triggered by various events like HTTP requests, timers, queues, etc.

• Azure Functions automatically scales based on dem...read more

Microservices are a software development technique where applications are composed of small, independent services that communicate with each other.

• Microservices break down applications into smaller, loosely coupled services

• Each service is responsible for a specific function and can be developed, deployed, and scaled independently

• Communication between services is typically done through APIs

• Examples of companies using mi...read more

Microservices are smaller, independent services that work together, while Monolithic is a single, large application.

• Microservices are smaller, independent services that can be developed, deployed, and scaled independently.

• Monolithic architecture is a single, large application where all components are tightly coupled.

• Microservices promote flexibility, scalability, and fault isolation.

• Monolithic applications are easier t...read more
