ASP.NET MVC interview questions and answers can assist a candidate in preparing well for a technical interview.

ASP.NET MVC is a web development framework for building web applications using the Model-View-Controller (MVC) architectural pattern.

The interview topics for chúng tôi MVC include MVC fundamentals, Razor syntax, controller actions, routing, filters, and deployment.

One important topic to prepare for is how to handle exceptions in an chúng tôi MVC application.

Another topic to know is authentication and authorization in chúng tôi MVC, including how to implement role-based security.

It’s essential to know the differences between ViewBag and ViewData, as well as how to use TempData to pass data between controller actions.

Part 1 – chúng tôi MVC Interview Questions (Basic) Q1. What is chúng tôi MVC?

ASP.NET MVC is a framework for building web applications using the Model-View-Controller architectural pattern.

The Model-View-Controller (MVC) pattern separates the application into three components:

Model: represents the data and business logic.

View: represents the user interface.

Controller: handles user input and updates the model and view accordingly.

Q2. How does chúng tôi MVC differ from chúng tôi Web Forms?

Answer:

Points ASP.NET MVC ASP.NET Web Forms

Approach Separates application logic into distinct layers and components It uses a page-based approach where each page represents a discrete user interface element

User interface Relies on HTML, CSS, and JavaScript for rendering Provides a rich set of server-side controls for creating interactive web pages

Flexibility and Customizability More flexible and customizable Less flexible and customizable

Expertise and Effort Required Requires more knowledge and effort to implement Easier to implement

Q3. How do Model, View, and Controller communicate with each other in chúng tôi MVC?

Answer:

The Controller receives input from the user, interacts with the model to retrieve data, and selects the view to display the data to the user.

The model represents the data and business logic of the application, and it can communicate with the database or other data sources to retrieve or store data.

The view is responsible for rendering the user interface, and it can receive data from the Controller to display to the user.

The Controller acts as an intermediary between the Model and View, passing data between them as needed.

The communication between these components is facilitated by a routing mechanism that maps incoming requests to the appropriate Controller and action method, which then interacts with the model and selects the appropriate view to render the response.

Q4. What is the difference between ViewBag and ViewData in chúng tôi MVC?

Answer:

Feature ViewBag ViewData

Definition A dynamic property that is used to share data between the Controller and View. A dictionary object is used to share data between the Controller and View.

Type of data stored Dynamic Object

Data accessibility Data is accessible using the dynamic property syntax. String-type keys are used to access data.

Data transfer It transfers data from the Controller to the view. It transfers data from the Controller to the view.

Data capacity It can store a small amount of data. It can store a small amount of data.

Data retention Data is retained during the current HTTP request only. Data is retained during the current HTTP request only.

Ease of use It is easier to use than ViewData as it allows the use of the dynamic property syntax. It is not as easy to use as ViewBag since it requires access keys.

Example syntax ViewBag.Message = “Welcome to MVC”; ViewData[“Message”] = “Welcome to MVC”;

Q5. What is the View engine, and what are its components?

Answer:

The view engine is a component in the chúng tôi MVC framework responsible for rendering HTML content and generating a response to the client. It uses a template-based approach to generate HTML output by combining data with markup.

The components of the view engine are:

View: This is the actual template that defines the Layout and structure of the HTML output. It contains placeholders for data that will be populated at runtime.

Model: This data will be used to populate the placeholders in the view. It can be a single object, a collection, or a data structure.

Controller: This component retrieves the data from the model and passes it to the view. It manages the interaction between the model and the view and acts as a mediator between them.

HTML Helper: This utility class simplifies the process of generating HTML content in the view. It provides methods for generating common HTML elements, such as input fields and buttons, and can be customized to meet specific requirements.

Part 2 – chúng tôi MVC Interview Questions (Advanced) Q6. What is Layout in chúng tôi MVC?

Answer:

A Layout in chúng tôi MVC is a template used to define the common structure or Layout of a web page.

It allows for defining the common user interface elements, such as headers, footers, menus, and sidebars, in a single file that can be shared across multiple views.

Layouts are created using a particular type of Razor view called a Layout view, typically named _Layout.cshtml or _Layout.vbhtml.

Layout views contain a mix of standard HTML markup and Razor syntax and are defined using the @model directive followed by the Layout’s model type.

For example, @model System.Web.Mvc.WebViewPage defines a layout view that can be used with any view that inherits from the WebViewPage class.

Example of Layout-

@RenderBody()

Q7. Explain filters with their sequence of working.

Answer:

In chúng tôi MVC, filters inject additional logic at various request-processing pipeline stages.

Authorization filters:

These filters are used to check whether the user is authorized to access a resource or not.

Authorization filters run first in the pipeline and are executed before the action method is called.

If an authorization filter fails, the pipeline is stopped, and the user is redirected to the login page or an error page.

Action filters:

These filters are executed before and after the execution of the action method.

They are used to modify the action method’s arguments, modify the view result, or add additional logic to the action method.

Action filters have four events: OnActionExecuting, OnActionExecuted, OnResultExecuting, and OnResultExecuted.

These filters modify the view result before returning it to the user.

The result filters run after the action method executes before the view is rendered.

Result filters have two events: OnResultExecuting and OnResultExecuted.

Exception filters:

These filters handle exceptions that occur during the request processing pipeline.

Exception filters run when an unhandled exception occurs in the action method, action filters, or result filters.

Exception filters have two events: OnException and OnResultExecuted.

The sequence of working filters is as follows:

Authorization filters are executed first.

Action filters execute before and after the action method executes.

Result filters execute after the action method executes but before the view renders.

Exception filters execute when an unhandled exception occurs in the action method, action filters, or result filters.

Q8. How can one implement AJAX in MVC?

Answer:

To implement AJAX in MVC, one can follow the below steps:

Include jQuery library: Download and include the jQuery library in the application.

Create an Action method: Create an action method that returns data in JSON format. This method will be called using AJAX.

Create a View: Create a view with a button or any other control to trigger the AJAX request.

Write AJAX code: Write an AJAX code that will call the action method and handle the response.

Handle the response: Handle the response returned from the action method and update the view accordingly.

Q9. What are the steps for implementing an MVC project?

Answer:

The steps for implementing an MVC project are as follows:

Create a new project: Open Visual Studio and create a new project. Select the chúng tôi Web Application (.NET Framework) template and choose MVC as the project type.

Choose a project template.

Add controllers

Add views

Define models

Configure routing

Build the application

Test the application

Publish the application

Q10. Explain navigation from one view to another view in MVC.

Answer:

The steps for navigation are as follows:

Define an Action method in a Controller that will be used for navigating to the desired view.

Use the HTML helper method, such as Html.ActionLink(), to create a link to the Action method in the view.

Specify the name of the Action method and the Controller that contains it in the HTML helper method.

Pass any necessary parameters to the Action method, such as an ID or a search string.

Define the Action method to return a View or a RedirectToAction result that will navigate to the desired view.

Use the return View() method to navigate to a view corresponding to the Action method or the RedirectToAction() method to navigate to a different Action method in the same or a separate Controller.

Use the TempData[] dictionary to pass data between the Action methods during navigation.

Display the data in the new view using the @Model or ViewBag object.

Key Highlights

Understanding the different components and their roles in DB2 architecture is crucial to answering questions on DB2 architecture in an interview.

Knowing the syntax, usage, and performance implications of complex SQL queries can help candidates demonstrate their SQL skills.

Familiarity with various data management features in DB2, such as backup and recovery, data compression, data partitioning, and data replication, can help candidates showcase their ability to manage data effectively.

Demonstrating knowledge of performance tuning can make a candidate stand out in an interview.

Well-versed candidates in authentication, authorization, encryption, and auditing features can demonstrate their ability to maintain data security and integrity in an enterprise environment.

Part 1 – DB2 Interview Questions (Basic) Q1. What is the picture clause in DB2? How can one use it in case of the null indicator variable?

In DB2, the picture clause is used to define the format of a data item. It specifies the number of digits, the position of the decimal point, and the type of data, such as alphabetic or numeric.

The picture clause can define the format of the null indicator field in the program in the case of a null indicator variable.

The picture clause for a null indicator variable must be S9(4) COMP, which specifies that it is a signed numeric field with a length of four bytes.

The first two bytes are used to store the length of the data item, and the second two bytes are used to store a binary value indicating whether the data item is null or not.

The picture clause ensures the correct formatting of the null indicator variable, enabling the checking of null values in the data.

Q2. Explain what a DB2 deadlock is and how it can be identified.

Answer:

A DB2 deadlock occurs when two or more transactions are waiting for each other to release resources needed to complete their work. Both transactions can become blocked, preventing them from proceeding and causing the application to hang or become unresponsive.

To identify DB2 deadlocks-

Enable tracing and monitoring tools, such as the IBM Data Server Manager or the DB2 Event Monitor, to capture and analyze the events and locks that occur during a transaction. These tools can help identify the resources causing the deadlock and the transactions involved.

Another method uses the DB2 administrative views and commands, such as the SYSIBMADM.SNAPLOCK table to monitor the locking activity and identify potential deadlocks.

DB2 utilities like the db2pd command or the db2top tool can display real-time lock and transaction information.

Q3. Every RDBMS database always follows some well-defined structure for the executed SQL statement in its environment. In the case of DB2, which component is responsible for executing the SQL statement? Explain with an example.

Answer:

In DB2, the component responsible for executing SQL statements is the DB2 SQL Processor. The SQL Processor receives the SQL statement from the application and performs the following steps:

Parsing: The SQL statement is parsed to identify its structure and validate its syntax. Any errors are reported back to the application.

Binding: The SQL statement is bound to the database objects it references, such as tables and indexes. This process checks the objects’ availability, verifies the user’s permissions, and generates an execution plan for the statement.

Optimization: The DB2 Optimizer optimizes the execution plan generated during binding to determine the most efficient way to access and manipulate the data.

Execution: The DB2 Access Manager executes the optimized execution plan, retrieves the data from the database, and returns the results to the application.

For example, consider the following SQL statement:

SELECT * FROM EMPLOYEE WHERE DEPT = ‘SALES’

When this statement executes, the SQL Processor will parse it to identify the SELECT and WHERE clauses, bind it to the EMPLOYEE table, optimize the execution plan to efficiently retrieve the rows with DEPT = ‘SALES’, and execute the plan to retrieve the desired results.

Q4. What is a DB2 index, and how does it work?

Answer:

An index in DB2 is a data structure that helps speed up queries on large tables by quickly allowing the database to find the rows that match specific criteria.

DB2 can use the index to quickly find the subset of rows that match the criteria specified in the WHERE clause rather than scanning the entire table when executing a query that includes a WHERE clause.

For example, if there is a table of customer orders with millions of rows, one can create an index on the “customer_id” column to speed up those queries.

Q5. One of the common approaches in the RDBMS database is expecting the average salary for an entire organization from a specific table using the common aggregator AVG. Is there any possibility of giving some wrong average value for any common mistake? If yes, explain the mistake and how we can recover the same.

Answer:

Yes, it is possible to give a wrong average value for an organization’s salary if the table contains NULL values for the salary column.

The AVG function in SQL considers only the non-NULL values to calculate the average.

If a column contains NULL values, the AVG function will exclude those values in its calculation, which can lead to a wrong average value.

To avoid this, one can use the COALESCE function to replace NULL values with a default value (e.g., 0) before calculating the average.

Alternatively, one can use the AVG function with the OVER clause and the ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING specification to include all rows in the calculation, regardless of their NULL values. By using this approach, the average can be calculated correctly even if there are NULL values in the column.

Part 2 – DB2 Interview Questions (Advanced) Q6. Which component handles DB2 database startup and shutdown?

The component responsible for handling DB2 database startup and shutdown is the DB2 Database Manager (DBM).

DBM is responsible for starting and stopping instances of the DB2 database, which are collections of databases managed as a single unit.

DBM can be started and stopped manually using the db2start and db2stop commands or automatically using operating system facilities such as systemd or init.d.

Shutting down DBM terminates all processes and services associated with the database instance and releases any system resources allocated to it.

Q7. Explain different types of locks in the DB2 database.

Answer:

Shared lock: A shared lock allows multiple transactions to read data but prevents them from modifying it. It is used for data that does not need to be updated frequently.

Exclusive lock: An exclusive lock allows transaction access to a piece of data, preventing other transactions from reading or updating it. It is used when data needs to be updated frequently.

Update lock: An update lock is similar to a shared lock in that it allows multiple transactions to read the data but reserves the right to update the data in the future. It ensures that another transaction does not update data before the current transaction can update it.

Intent lock: An intent lock indicates the type of lock a transaction intends to use on a piece of data. It is used to simplify lock management in complex transactions.

Row-level lock: A row-level lock allows a transaction to lock a specific row in a table, preventing other transactions from accessing or updating that row. It is used when a transaction needs to update a small portion of a table.

Table-level lock: A table-level lock locks an entire table, preventing other transactions from accessing or updating any data. It is used when a transaction needs to update a large portion of a table.

Q8. Explain isolation levels. At what level can it be added?

Answer:

In DB2, one can specify the isolation level for the binding step.

DB2 defines the binding step as the compilation process on the database platform.

BIND ensures the proper compilation of Cobol programming.

It helps to DB2 optimizer for preparing the SQL statement in the executable code. 

Q9. Execution of DML statements like UPDATE, INSERT and DELETE impacts some number of rows. Which field helps to show the number of rows in SQLCA?

Answer:

To check how many rows have been impacted or updated, it is necessary to validate SQLERRD, which contains that information.

Q10. What will be the defined length of physical storage for storing the timestamp in the IBM Db2 database?

Answer:

Timestamps normally occupy 10 bytes. They store in the YYYY-MM-DD HH:MM: SS: NNNNNN format.

Final Thoughts

A thorough comprehension of database fundamentals and strong technical proficiency in SQL and data administration is necessary for DB2 interview preparation. Being familiar with the DB2 platform and related tools is also crucial. A variety of subjects, including database architecture, data modeling, database administration, performance tuning, and troubleshooting, may be covered in DB2 interview questions. Moreover, Showing that the candidate can work cooperatively with a team and solve problems is crucial. One can feel more secure and prepared to demonstrate your abilities and knowledge in a DB2 interview by studying these critical topics and rehearsing answers to typical interview questions.

Frequently Asked Questions (FAQs)

Answer: DB2 interview questions are questions that an interviewer may ask to assess a candidate’s knowledge and expertise in the DB2 database management system. Some common questions involve-

2. What are the four environments which can access DB2?
