NET Framework interview questions and interviewer's notes
.NET framework overview
1. Has own class libraries. System is the main namespace and all other namespaces are subsets of this.
2. It has CLR(Common language runtime, Common type system, common language specification)
3. All the types are part of CTS and Object is the base class for all the types.
4. If a language said to be .net complaint, it should be compatible with CTS and CLS.
5. All the code compiled into an intermediate language by the .Net language compiler, which is nothing but an assembly.
6. During runtime, JIT of CLR picks the IL code and converts into PE machine code and from there it processes the request.
8. Garbage Collection
9. Dispose, finalize, suppress finalize, Idispose interface

3. Dataset (collection of tables)
4. CommandBuiler object
5. Transaction Object
6. Isolation levels

1. How do you register a component?
Expected answer:
Compiling the component, running REGSVR32 MyDLL.dll
2. Name and explain the different compatibility types when creating a COM component.
Expected answer:
No Compatibility ? New GUID created, references from other components will not work
Project Compatibility ? Default for a new component <Not as critical to mention this one>
Binary Compatibility ? GUID does not change, references from other components will work
3. Why is it important to use source control software for source code?
Expected answer:
Modification history.
Code ownership: Multiple people can not modify the same code at the same time.
4. What two methods are called from the ObjectContext object to inform MTS that the transaction was successful or unsuccessful?
Expected answer:
SetComplete and SetAbort.
5. What is the tool used to configure the port range and protocols for DCOM communications?
Expected answer:
6. What does Option Explicit refer to?
Expected answer:
All variables must be declared before use. Their type is not required.
7. What are the different ways to Declare and Instantiate an object in Visual Basic 6?
Expected answer:
Dim obj as OBJ.CLASS with either
Set obj = New OBJ.CLASS or
Set obj = CreateObject(?OBJ.CLASS?) or
Set obj = GetObject( ,? OBJ.CLASS?)
Dim obj as New OBJ.CLASS
8. Name the four different cursor types in ADO and describe them briefly.
Expected Answer:
The cursor types are listed from least to most resource intensive.
Forward Only ? Fastest, can only move forward in recordset
Static ? Can move to any record in the recordset. Data is static and never changes.
KeySet ? Changes are detectable, records that are deleted by other users are unavailable, and records created by other users are not detected
Dynamic ? All changes are visible.
9. Name the four different locking type in ADO and describe them briefly.
Expected Answer:
LockPessimistic ? Locks the row once after any edits occur.
LockOptimistic ? Locks the row only when Update is called.
LockBatchOptimistic ? Allows Batch Updates.
LockReadOnly ? Read only. Can not alter the data.
10. Describe Database Connection pooling (relative to MTS )
Expected Answer:
This allows MTS to reuse database connections. Database connections are put to ?sleep? as opposed to being created and destroyed and are activated upon request.
11. What are the ADO objects? Explain them. Provide a scenario using three of them to return data from a database.
Expected Answer:
Connection ? Connects to a data source; contains the Errors collection
Command ? Executes commands to the data source. Is the only object that can accept parameters for a stored procedure.
Recordset ? The set of data returned from the database.
Scenario: There are many possibilities. The most likely is as follows:
Dim conn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim Cmd As ADODB.Command
conn.ConnectionString = ?CONNECTION STRING?
Set Cmd.ActiveConnection = conn
Cmd.CommandText = ?SQL STATEMENT?
Set rs = Cmd.Execute
Set rs.ActiveConnection = Nothing
12. Under the ADO Command Object, what collection is responsible for input to stored procedures?
Expected answer:
The Parameters collection.
13. What are some benefits of using MTS?
Expected answer:
Database Pooling, Transactional operations, Deployment, Security, Remote Execution.
14. What is the benefit of wrapping database calls into MTS transactions?
Expected answer:
If database calls are made within the context of a transaction, aborting the transaction will undo and changes that occur within that transaction. This removes the possibility of stranded, or partial data.
15. Describe and In Process vs. Out of Process component. Which is faster?
Expected answer:
An in-process component is implemented as a DLL, and runs in the same process space as its client app, enabling the most efficient communication between client and component.Each client app that uses the component starts a new instance of it.
An out of process component is implemented as an EXE, and unlike a dll, runs in its own process space. As a result, exe's are slower then dll's because communications between client and component must be marshalled across process boundaries. A single instance of an out of process component can service many clients.
15. What are the main components of the ADO object model? How are they used?
Expected answer:
Connection: Used to make a connection between your app and an external data source, ie, sql server.
Command: Used to build queries, including user-specific parameters, to access records from a data source (which are returned in a Recordset)
Recordset:Used to access records returned from an SQL query. With a recordset, you can navigate returned records. You can also add, modify or delete records.
UML Questions used by a software company :
Q. What does "object-oriented" mean to you?
Q. Can you name the four phases of the Unified Process?
A. Inception
Q. What can you tell us about the different phases of the Unified Process?
Q. Talk about some OO/UML artifacts you have used. What did they mean to you? How did you apply them to yout project?
Q. What is a "use case"?
A. A complete end-to-end business process that satisfies the needs of a user.
Q. What are different categories of use cases?
A. Detail Level: - High level / Expanded
Task Level: - Super / Sub (Abstract; Equal Alternatives; Complete v. Partial)
Importance: - Primary / Secondary (use Secondary for exceptional processes)
Abstraction: - Essential / Real
Q. What is the difference between a real and essential use case?
A. essential - describes the "essence" of the problem; technology independent
real - good for GUI designing; shows problem as related to technology decisions
Q. What is polymorphism?
A. Different objects reacting to the same message differently.
Q. In a System Sequence Diagram, what is a System Event?
A. It is from the expanded use case. It is an actor action the system directly responds to.
Q. Give an example of a situation which a State Diagram could effectively model.
A. Think of a cake and its different stages through the baking process: dough, baked, burned.
Q. For what are Operations Contracts written?
A. System Events.
Q. In an Operations Contract's postconditions, four types of activities are specified. What are they?
A. They are:
instances created
associations formed
associations broken
attributes changed
Q. What does an Operations Contract do?
A. Provides a snapshot of the System's state before and after a System Event. It is not interested in the Event's specific behavior.
Q. What does a Collaboration Diagram (or Sequence Event, depending on the process) model?
A. A System Event's behavior.
Q. How does one model a class in a Collaboration Diagram? An instance?
A. A box will represent both; however, a class is written as MyClass whereas an instance is written as myInstance:MyClass.
Q. What are the three parts of a class in a Class Diagram?
A. Name, Attributes, Methods.
Q. In Analysis, we are interested in documenting concepts within the relevant problem domain. What is a concept?
A. A person, place, thing, or idea that relates to the problem domain. They are candidates for objects.
Q. Does a concept HAVE to become a class in Design?
A. No.
Q. In a Class Diagram, what does a line with an arrow from one class to another denote?
A. Attribute visibility.
Q. What are the four types of visibility between objects?
A. Local, parameter, attribute, global.
Q. Have you ever used any Design Patterns?
Q. When do you use inheritance as opposed to aggregation?
A. An aggregation is a "has a" relationship, and it is represented in the UML by a clear diamond. An example of an aggregate relation is Table of Contents and Chapter. A Table of Contents "has a" Chapter.
Q. When would I prefer to use composition rather than aggregation?
A. Composition is a stronger form of aggregation. The object which is "contained" in another object is expected to live and die with the object which "contains" it. Composition is represented in the UML by a darkened diamond. An example of a composite relation is a Book and Chapter. A Book "has a" Chapter, and the Chapter cannot exist without the Book.
Q. Is the UML a process, method, or notation?
A. It is a notation. A process is Objectory, Booch, OMT, or the Unified Process. A process and a notation together make an OO method.
Q. What are two uses for inheritance?
A. specialization - "IS A KIND OF" relationship
abstraction - pull a common concept out to a higher level to make it more generic
Q. When would you use an abstract base class
A. When you need to enforce a particular interface, but are not able or do not need to define behavior at the base class level.
Q. All containers are pretty well templatized now. Can you think of any current "example" (e.g., an algorithm) which is implemented via inheritance but might be more efficiently implemented using templates?
Q. Can you tell us some good principles to use in OOA&D?
A. NOTE: This is not a complete list, by any means, but we have listed the GRASP Patterns here for examples (these help assign responsibilities between objects):
Low coupling
High cohesion
Don't Talk to Strangers
Pure Fabrication
Q. What are some practicle benefits we can gain from a well-designed OO system?
1. What is a Cartesian product? What causes it?
Expected answer:
A Cartesian product is the result of an unrestricted join of two or more tables. The result set of a three table Cartesian product will have x * y * z number of rows where x, y, z correspond to the number of rows in each table involved in the join. It is causes by specifying a table in the FROM clause without joining it to another table.
2. What is an advantage to using a stored procedure as opposed to passing an SQL query from an application.
Expected answer:
A stored procedure is pre-loaded in memory for faster execution. It allows the DBMS control of permissions for security purposes. It also eliminates the need to recompile components when minor changes occur to the database.
3. What is the difference of a LEFT JOIN and an INNER JOIN statement?
Expected answer:
A LEFT JOIN will take ALL values from the first declared table and matching values from the second declared table based on the column the join has been declared on. An INNER JOIN will take only matching values from both tables
4. When a query is sent to the database and an index is not being used, what type of execution is taking place?
Expected answer:
A table scan.
5. What are the pros and cons of using triggers?
Expected answer:
A trigger is one or more statements of SQL that are being executed in event of data modification in a table to which the trigger belongs.
Triggers enhance the security, efficiency, and standardization of databases.
Triggers can be beneficial when used:
-- to check or modify values before they are actually updated or inserted in the database. This is useful if you need to transform data from the way the user sees it to some internal database format.
-- to run other non-database operations coded in user-defined functions
-- to update data in other tables. This is useful for maintaining relationships between data or in keeping audit trail information.
-- to check against other data in the table or in other tables. This is useful to ensure data integrity when referential integrity constraints aren't appropriate, or when table check constraints limit checking to the current table only.

3. Can Windows Server 2003 function as a bridge? Yes, and it's a new feature for the 2003 product. You can combine several networks and devices connected via several adapters by enabling IP routing.
4. What's the difference between the basic disk and dynamic disk? The basic type contains partitions, extended partitions, logical drivers, and an assortment of static volumes; the dynamic type does not use partitions but dynamically manages volumes and provides advanced storage options
5. What's a media pool? It is any compilation of disks or tapes with the same administrative properties.
6. How do you install recovery console? C:\i386\win32 /cmdcons, assuming that your Win server installation is on drive C.
7. What's new in Terminal Services for Windows 2003 Server? Supports audio transmissions as well, although prepare for heavy network load.
8. What scripts ship with IIS 6.0? iisweb.vsb to create, delete, start, stop, and list Web sites, iisftp.vsb to create, delete, start, stop, and list FTP sites, iisdir.vsb to create, delete, start, stop, and display virtual directories, iisftpdr.vsb to create, delete, start, stop, and display virtual directories under an FTP root, iiscnfg.vbs to export and import IIS configuration to an XML file.

11. What's the relation between SSL and TLS? Transport Layer Security (TLS) extends SSL by providing cryptographic authentication.
12. What's the role of http.sys in IIS? It is the point of contact for all incoming HTTP requests. It listens for requests and queues them until they are all processed, no more queues are available, or the Web server is shut down.
13. Where's ASP cache located on IIS 6.0? On disk, as opposed to memory, as it used to be in IIS 5.
14. What is socket pooling? Non-blocking socket usage, introduced in IIS 6.0. More than one application can use a given socket.
15. Describe the process of clustering with Windows 2003 Server when a new node is added. As a node goes online, it searches for other nodes to join by polling the designated internal network. In this way, all nodes are notified of the new node's existence. If other nodes cannot be found on a preexisting cluster, the new node takes control of the quorum resources residing on the shared disk that contains state and configuration data.
16. What applications are not capable of performing in Windows 2003 Server clusters? The ones written exclusively for NetBEUI and IPX.
17. What's a heartbeat? Communication processes between the nodes designed to ensure node's health.
18. What's a threshold in clustered environment? The number of times a restart is attempted, when the node fails.
19. You need to change and admin password on a clustered Windows box, but that requires rebooting the cluster, doesn't it? No, it doesn't. In 2003 environment you can do that via cluster.exe utility which does not require rebooting the entire cluster.
20. For the document of size 1 MB, what size would you expect the index to be with Indexing Service? 150-300 KB, 15-30% is a reasonable expectation.
21. Doesn't the Indexing Service introduce a security flaw when allowing access to the index? No, because users can only view the indices of documents and folders that they have permissions for.
22. What's the typical size of the index? Less then 100K documents - up to 128 MB. More than that - 256+ MB.
23. Which characters should be enclosed in quotes when searching the index? &, @, $, #, ^, ( ), and |.
24. How would you search for C++? Just enter C++, since + is not a special character (and neither is C).
25. What about Barnes&Noble? Should be searched for as Barnes'&'Noble.
26. Are the searches case-sensitive? No.

2. What do you do if earlier application doesn't run on Windows Server 2003? When an application that ran on an earlier legacy version of Windows cannot be loaded during the setup function or if it later malfunctions, you must run the compatibility mode function. This is accomplished by right-clicking the application or setup program and selecting Properties --> Compatibility --> selecting the previously supported operating system.
3. If you uninstall Windows Server 2003, which operating systems can you revert to? Win ME and Win 98.
4. How do you get to Internet Firewall settings? Start --> Control Panel --> Network and Internet Connections --> Network Connections.
5. What are the Windows Server 2003 keyboard shortcuts? Winkey opens or closes the Start menu. Winkey + BREAK displays the System Properties dialog box. Winkey + TAB moves the focus to the next application in the taskbar. Winkey + SHIFT + TAB moves the focus to the previous application in the taskbar. Winkey + B moves the focus to the notification area. Winkey + D shows the desktop. Winkey + E opens Windows Explorer showing My Computer. Winkey + F opens the Search panel. Winkey + CTRL + F opens the Search panel with Search for Computers module selected. Winkey + F1 opens Help. Winkey + M minimizes all. Winkey + SHIFT+ M undoes minimization. Winkey + R opens Run dialog. Winkey + U opens the Utility Manager. Winkey + L locks the computer.
6. What is Active Directory? Active Directory is a network-based object store and service that locates and manages resources, and makes these resources available to authorized users and groups. An underlying principle of the Active Directory is that everything is considered an object—people, servers, workstations, printers, documents, and devices. Each object has certain attributes and its own security access control list (ACL).
7. Where are the Windows NT Primary Domain Controller (PDC) and its Backup Domain Controller (BDC) in Server 2003? The Active Directory replaces them. Now all domain controllers share a multimaster peer-to-peer read and write relationship that hosts copies of the Active Directory.
8. How long does it take for security changes to be replicated among the domain controllers? Security-related modifications are replicated within a site immediately. These changes include account and individual user lockout policies, changes to password policies, changes to computer account passwords, and modifications to the Local Security Authority (LSA).
9. What's new in Windows Server 2003 regarding the DNS management? When DC promotion occurs with an existing forest, the Active Directory Installation Wizard contacts an existing DC to update the directory and replicate from the DC the required portions of the directory. If the wizard fails to locate a DC, it performs debugging and reports what caused the failure and how to fix the problem. In order to be located on a network, every DC must register in DNS DC locator DNS records. The Active Directory Installation Wizard verifies a proper configuration of the DNS infrastructure. All DNS configuration debugging and reporting activity is done with the Active Directory Installation Wizard.
10. When should you create a forest? Organizations that operate on radically different bases may require separate trees with distinct namespaces. Unique trade or brand names often give rise to separate DNS identities. Organizations merge or are acquired and naming continuity is desired. Organizations form partnerships and joint ventures. While access to common resources is desired, a separately defined tree can enforce more direct administrative and security restrictions.
11. How can you authenticate between forests? Four types of authentication are used across forests: (1) Kerberos and NTLM network logon for remote access to a server in another forest; (2) Kerberos and NTLM interactive logon for physical logon outside the user's home forest; (3) Kerberos delegation to N-tier application in another forest; and (4) user principal name (UPN) credentials.
12. What snap-in administrative tools are available for Active Directory? Active Directory Domains and Trusts Manager, Active Directory Sites and Services Manager, Active Directory Users and Group Manager, Active Directory Replication (optional, available from the Resource Kit), Active Directory Schema Manager (optional, available from adminpak)
13. What types of classes exist in Windows Server 2003 Active Directory?
o Structural class. The structural class is important to the system administrator in that it is the only type from which new Active Directory objects are created. Structural classes are developed from either the modification of an existing structural type or the use of one or more abstract classes.
o Abstract class. Abstract classes are so named because they take the form of templates that actually create other templates (abstracts) and structural and auxiliary classes. Think of abstract classes as frameworks for the defining objects.
o Auxiliary class. The auxiliary class is a list of attributes. Rather than apply numerous attributes when creating a structural class, it provides a streamlined alternative by applying a combination of attributes with a single include action.
o 88 class. The 88 class includes object classes defined prior to 1993, when the 1988 X.500 specification was adopted. This type does not use the structural, abstract, and auxiliary definitions, nor is it in common use for the development of objects in Windows Server 2003 environments.
14. How do you delete a lingering object? Windows Server 2003 provides a command called Repadmin that provides the ability to delete lingering objects in the Active Directory.
15. What is Global Catalog? The Global Catalog authenticates network user logons and fields inquiries about objects across a forest or tree. Every domain has at least one GC that is hosted on a domain controller. In Windows 2000, there was typically one GC on every site in order to prevent user logon failures across the network.
16. How is user account security established in Windows Server 2003? When an account is created, it is given a unique access number known as a security identifier (SID). Every group to which the user belongs has an associated SID. The user and related group SIDs together form the user account's security token, which determines access levels to objects throughout the system and network. SIDs from the security token are mapped to the access control list (ACL) of any object the user attempts to access.
17. If I delete a user and then create a new account with the same username and password, would the SID and permissions stay the same? No. If you delete a user account and attempt to recreate it with the same user name and password, the SID will be different.
18. What do you do with secure sign-ons in an organization with many roaming users? Credential Management feature of Windows Server 2003 provides a consistent single sign-on experience for users. This can be useful for roaming users who move between computer systems. The Credential Management feature provides a secure store of user credentials that includes passwords and X.509 certificates.
19. Anything special you should do when adding a user that has a Mac? "Save password as encrypted clear text" must be selected on User Properties Account Tab Options, since the Macs only store their passwords that way.
20. What remote access options does Windows Server 2003 support? Dial-in, VPN, dial-in with callback.
21. Where are the documents and settings for the roaming profile stored? All the documents and environmental settings for the roaming user are stored locally on the system, and, when the user logs off, all changes to the locally stored profile are copied to the shared server folder. Therefore, the first time a roaming user logs on to a new system the logon process may take some time, depending on how large his profile folder is.
22. Where are the settings for all the users stored on a given machine? \Document and Settings\All Users
23. What languages can you use for log-on scripts? JavaScipt, VBScript, DOS batch files (.com, .bat, or even .exe)


  1. very gud thought really it is helpful to most of the people i mean it

  2. Aw, this was an exceptionally good post. Spending some time and actual effort to make a superb article… but what can I say… I
