Answer #

  • Windows authentication and IIS.
  • Passport authentication.
  • Forms authentication.
  • After your application has authenticated users, you can proceed to authorize their access to resources.

Question # 62 Which authentication uses a combination of Windows and IIS authentication?

Answer # In IIS7, ASP.NET is integrated into the request pipeline, and the composite effect is that there is only one authentication mechanism to maintain. Passport authentication uses Microsoft’s Windows Live ID Authentication (formally .NET Passport), which you have to be licensed to use.

Question # 63 What is the default authentication mode for asp net?

Answer # Windows authentication is used together with IIS authentication. Authentication is performed by IIS in the following ways: basic, digest, or Integrated Windows Authentication. When IIS authentication is complete, ASP.NET uses the authenticated identity to authorize access. This is the default setting.

Question # 64 What is the difference between authentication and authorization?

Answer # When you log on to a PC with a user name and password you are authenticating. Authorization is the process of verifying that you have access to something. Gaining access to a resource (e.g. directory on a hard disk) because the permissions configured on it allow you access is authorization.

Question # 70 What is the differences between a Primary key and a Unique key in SQL server?

Answer # Primary Key is used to identify a row (record) in a table, whereas Unique-key is to prevent duplicate values in a column (with the exception of a null entry). By default SQL-engine creates Clustered Index on primary-key if not exists and Non-Clustered Index on Unique-key.

ASP.NET Real Time Interview Questions And Answers

Question # 71 What are the differences between primary foreign and unique keys?

Answer # A primary key is a column or a set of columns that uniquely identify a row in a table. A primary key should be short, stable and simple.

A foreign key is a field (or collection of fields) in a table whose value is required to match the value of the primary key for a second table. A table can have multiple foreign keys.

Question # 72 What is the difference between a candidate key and primary key?

Answer # Candidate Key – A Candidate Key can be any column or a combination of columns that can qualify as unique key in database. There can be multiple Candidate Keys in one table. Each Candidate Key can qualify as Primary Key.

Primary Key – A Primary Key is a column or a combination of columns that uniquely identify a record.

Question # 73 Can the unique key be null?

Answer # One row in the database is allowed to have null for the value of the unique key constraint.

Question # 74 Can I have a unique key as foreign key?

A FOREIGN KEY constraint does not have to be linked only to a PRIMARY KEY constraint in another table; it can also be defined to reference the columns of a UNIQUE constraint in another table. So in your case if you make AnotherID unique, it will be allowed.

Question # 75 How may clustered index we can create in table?

Answer # Generally we can create only one clustered index in a table, but if required there is a way to create more clustered index in a table.

Question # 76 What is the difference between clustered and nonclustered index?

Answer # A clustered index actually describes the order in which records are physically stored on the disk, hence the reason you can only have one. A Non-Clustered Index defines a logical order that does not match the physical order on disk.

Question # 77 What is distributed system in ASP.NET?

Answer # A distributed system is a network that consists of autonomous computers that are connected using a distribution middleware. They help in sharing different resources and capabilities to provide users with a single and integrated coherent network.

Question # 79 What is difference between Web API and Web services?

Answer # Web Services are based on the SOAP protocol. Web API is a newer Microsoft framework which helps you to build REST based interfaces. The response can be either JSON or XML, but there is no way to generate clients automatically because Web Api does not offer a service description like the WSDL from Web Services.

Question # 80 What is Web API vs WCF?

Answer # While WCF is a unified framework for building service oriented applications, Web API is a light weight alternative to build RESTful services that can be consumed by many different clients. RESTful services use basic HTTP and are simple with much less payload compared to SOAP services.

Question # 81 What is difference between REST and SOAP?

Answer # Web services are of two kinds: Simple Object Access Protocol (SOAP) and Representational State Transfer (REST). SOAP defines a standard communication protocol (set of rules) specification for XML-based message exchange. SOAP uses different transport protocols, such as HTTP and SMTP.

Question # 82 Why Web API is better than WCF?

Answer # Since WCF is SOAP based, which uses standard XML schema over HTTP, it could lead to slower performance. WEB API is a better choice for simpler, light weight services. WEB API can use any text format including XML and is faster than WCF. WEB API can be used to create full-blown REST Services.

Question # 83 What is the difference between rest and restful?

Answer # Representational state transfer (REST) is a style of software architecture. As described in a dissertation by Roy Fielding, REST is an “architectural style” that basically exploits the existing technology and protocols of the Web. RESTful is typically used to refer to web services implementing such an architecture.

They are separate files containing functions that can be called by programs and other DLLs to perform computations and functions. DLL: They can be reused for some other application.

Question # 87 What is the GAC?

Answer # The Global Assembly Cache (GAC) is a folder in Windows directory to store the .NET assemblies that are specifically designated to be shared by all applications executed on a system.

Question # 88 What is strong-typing versus weak-typing? Which is preferred?

Answer #

Strong typing: It checks the type of variables  as soon as possible, usually at compile time. It  prevents mixing operations between mismatched types.

Weak Typing: While weak typing is delaying checking the types of the system as late as possible, usually to run-time. In this you can mix types without an explicit conversion.

A “weak-typed” programming language is simply one which is not strong-typed.

which is preferred depeneds on what you want. for scripts and good stuff you will usually want weak typing, because you want to write as much less code as possible. in big programs, strong typing can reduce errors at compile time.

Question # 89 What is the difference between equals() and == in c#?

Answer # The only difference between Equal and == is on object type comparison. in other cases, such as reference types and value types, they are almost the same(either both are bit-wise equality or both are reference equality). The == operator can be used to compare two variables of any kind, and it simply compares the bits.

Question # 90 What is boxing and unboxing in asp.net?

Answer # Boxing is the process of converting a value type to the type object or to any interface type implemented by this value type. When the CLR boxes a value type, it wraps the value inside a System.Object and stores it on the managed heap. Unboxing extracts the value type from the object.

Question # 91 What is Reflection?

Answer # With reflection we can dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties. We can also access attribute information using reflection.

Question # 92 What is full trust in ASP.NET?

Answer # Full trust is the default, allows ASP.NET applications to execute native code, to read from the Registry and Windows Event Log, and to read and write to files outside of the application’s virtual directory. In short, with full trust one web application could delete the entire contents of another web application.

Question # 93 What is the difference between debug and release?

Answer # The biggest difference between these is that: In a debug build the complete symbolic debug information is emitted to help while debugging applications and also the code optimization is not taken into account.
