10+ Raqeeb Technologies Interview Questions and Answers

Yes, a combination of transient and scoped lifetime services can work together.

• Transient services are created each time they are requested, while scoped services are created once per request within the scope.

• They can work together as long as the transient service does not depend on the scoped service for its functionality.

• For example, a logging service can be transient while a database context service can be scoped.

Firewall is a network security system that monitors and controls incoming and outgoing network traffic.

• Firewall acts as a barrier between a trusted internal network and untrusted external network

• It can be used to block unauthorized access to a network

• It can also be used to block outgoing traffic to prevent data leakage

• Firewalls can be hardware or software-based

• Examples of firewalls include Cisco ASA, Fortinet FortiGate, and pfSense

Dependency injection in core with types is a common practice in software engineering.

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

• Using dependency injection in core allows for easier testing and maintenance of the codebase.

• Types in dependency injection help ensure that the correct dependencies are injected into components.

• Examples include using frameworks like Spring for dependency injection in Jav...read more

Network segmentation can be implemented by creating separate subnetworks and controlling access between them.

• Identify the different types of data and systems that need to be protected

• Create separate subnetworks for each type of data/system

• Use firewalls and access controls to control traffic between subnetworks

• Regularly review and update the segmentation strategy

• Example: separating guest Wi-Fi network from corporate network

Dependency Injection is a design pattern where the dependencies of an object are provided externally rather than created within the object itself.

• Dependencies are injected into a class through constructor injection, setter injection, or interface injection.

• This helps in achieving loose coupling between classes and makes the code more testable and maintainable.

• Example: Instead of creating an instance of a database connection within a class, the connection is passed to the clas...read more

Middleware is used to handle requests and responses in web applications. Custom middleware can be created to add specific functionality.

• Middleware is software that acts as a bridge between an operating system or database and applications, allowing them to communicate with each other.

• Middleware can be used to handle tasks such as authentication, logging, error handling, and more.

• Custom middleware can be created to add specific functionality that is not provided by existing mid...read more

Authentication and authorization are essential for securing web APIs in ASP.NET Core.

• Use authentication to verify the identity of the user accessing the API.

• Use authorization to determine what actions the authenticated user is allowed to perform.

• In ASP.NET Core, authentication can be implemented using various schemes like JWT, OAuth, or Identity.

• Authorization can be achieved through policies, roles, or claims.

• Always validate user input and sanitize data to prevent security vu...read more

Different kinds of views that can be created include materialized views, virtual views, and dynamic views.

• Materialized views store the result set of a query physically and are updated periodically.

• Virtual views are based on SQL queries and do not store data physically.

• Dynamic views are created on the fly based on user input or system conditions.

• Other types of views include read-only views, updatable views, and recursive views.

I manage currency conversion scenarios by utilizing exchange rates, automated tools, and monitoring market trends.

• Utilize exchange rates provided by financial institutions or APIs

• Use automated tools or software for accurate and efficient conversions

• Monitor market trends and adjust conversion strategies accordingly

I manage currency conversion problems by closely monitoring exchange rates, using hedging strategies, and collaborating with financial experts.

• Monitor exchange rates regularly to identify trends and potential risks

• Utilize hedging strategies such as forward contracts or options to mitigate currency fluctuations

• Collaborate with financial experts or consultants to develop effective currency risk management strategies

• Diversify currency exposure to reduce reliance on a single curr...read more

A data warehouse is a centralized repository that stores structured and unstructured data from various sources for analysis and reporting.

• Data warehouses are designed for query and analysis rather than transaction processing.

• They typically store historical data and are used for creating reports, dashboards, and data visualizations.

• Data warehouses often use ETL (extract, transform, load) processes to integrate data from different sources.

• Examples of data warehouse technologies...read more
