# ASP.NET Core 요청 수명 주기 (.NET) > Request pipeline, middleware pipeline, filters, action results, model binding - 20 면접 질문 - Junior - [면접 질문: .NET](https://sharpskill.dev/ko/technologies/dotnet/interview-questions.md) ## 1. ASP.NET Core에서 request pipeline의 주요 역할은 무엇입니까? **답변** request pipeline은 Program.cs에 구성된 middleware를 통해 각 HTTP 요청을 순차적으로 처리합니다. 각 middleware는 요청을 다음 middleware로 전달하기 전에 검사하거나 수정하거나 short-circuit할 수 있습니다. 이 chain-of-responsibility 패턴은 관심사 분리(인증, logging, 압축 등)와 요청 처리의 모듈식 구성을 가능하게 합니다. ## 2. ASP.NET Core 파이프라인에서 middleware 순서의 중요성은 무엇입니까? **답변** middleware 순서는 중요합니다. 요청은 위에서 아래로 처리되고, 그다음 응답은 아래에서 위로 돌아가기 때문입니다. 인증 middleware를 routing 뒤에 배치하면 endpoint가 검증 없이 노출되어 보안 문제가 발생합니다. 일반적인 순서는 다음과 같습니다: Exception Handling → HTTPS Redirection → Static Files → Routing → CORS → Authentication → Authorization → Endpoints. ## 3. middleware는 어떻게 request pipeline을 short-circuit할 수 있습니까? **답변** middleware는 next()를 통해 요청을 다음 middleware로 전달하지 않음으로써 short-circuit할 수 있습니다. 이는 401 Unauthorized를 반환하는 인증 middleware, routing을 호출하지 않고 정적 파일을 제공하는 경우, 또는 비즈니스 로직을 실행하지 않고 캐시된 응답을 반환하는 caching 구현에 유용합니다. short-circuit은 불필요한 middleware 실행을 피해 성능을 향상시킵니다. ## 17개 추가 질문 이용 가능 - ASP.NET Core에서 model binding의 주요 소스는 무엇입니까? - IActionResult와 ActionResult의 차이점은 무엇입니까? 무료로 가입하기: https://sharpskill.dev/ko/login ## 기타 .NET 면접 주제 - [C# 기초](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/csharp-basics.md): 25개 질문, Junior - [LINQ & Delegates](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/csharp-linq-delegates.md): 20개 질문, Junior - [C# 언어 핵심 요소](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/csharp-language-essentials.md): 15개 질문, Junior - [ASP.NET Core 기초](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/aspnet-core-fundamentals.md): 18개 질문, Junior - [Configuration & Settings](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/configuration-settings.md): 20개 질문, Junior - [애플리케이션 라이프사이클](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/application-lifecycle.md): 20개 질문, Junior - [Dependency Injection](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/dependency-injection.md): 24개 질문, Mid-Level - [Entity Framework Core](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/entity-framework-core.md): 25개 질문, Mid-Level - [Minimal APIs](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/minimal-apis.md): 18개 질문, Mid-Level - [Web API 개발](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/web-api-development.md): 22개 질문, Mid-Level - [ASP.NET Core의 Async](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/async-aspnet-core.md): 20개 질문, Mid-Level - [Authentication & Authorization](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/authentication-authorization.md): 18개 질문, Mid-Level - [HttpClient & 네트워킹](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/httpclient-networking.md): 20개 질문, Mid-Level - [JSON 직렬화](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/json-serialization.md): 20개 질문, Mid-Level - [Entity Framework Core 고급](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/ef-core-advanced.md): 25개 질문, Mid-Level - [C# 고급 기능](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/csharp-advanced-features.md): 20개 질문, Mid-Level - [Clean Architecture](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/clean-architecture.md): 20개 질문, Mid-Level - [Logging, Monitoring & Observability](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/logging-monitoring.md): 22개 질문, Mid-Level - [단위 테스트와 xUnit](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/unit-testing-xunit.md): 20개 질문, Mid-Level - [통합 테스트](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/integration-testing.md): 18개 질문, Mid-Level - [Docker & Containerization](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/docker-containerization.md): 16개 질문, Mid-Level - [NuGet 패키지 관리](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/nuget-package-management.md): 16개 질문, Mid-Level - [Memory Management & GC](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/memory-management-gc.md): 22개 질문, Senior - [리액티브 프로그래밍](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/reactive-programming.md): 24개 질문, Senior - [Async/await 및 패턴](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/async-await-patterns.md): 26개 질문, Senior - [.NET 디자인 패턴](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/dotnet-design-patterns.md): 24개 질문, Senior - [성능 최적화](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/performance-optimization.md): 22개 질문, Senior - [보안 및 모범 사례](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/security-best-practices.md): 24개 질문, Senior - [SignalR 및 실시간](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/signalr-realtime.md): 22개 질문, Senior - [마이크로서비스 아키텍처](https://sharpskill.dev/ko/technologies/dotnet/interview-questions/microservices-architecture.md): 25개 질문, Senior --- Source: SharpSkill (https://sharpskill.dev), tech interview preparation for your real stack.
