Database security testing includes authentication and ____________ testing to ensure only authorized users can access the database.
- Authorization
- Integrity
- Penetration
- Vulnerability
Authentication testing in database security ensures that only authorized users can access the database. Authorization, on the other hand, involves defining and controlling access rights for different users or user roles. It is important to distinguish between authentication, which verifies the identity of a user, and authorization, which determines what actions the user is allowed to perform.
Scenario: You are leading the database testing process for a new e-commerce platform. During testing, you encounter a discrepancy between the expected and actual results of a complex SQL query. What should be your immediate action?
- Analyze the database schema for inconsistencies
- Check for errors in the SQL query itself
- Review the data in the test environment
- Verify the query execution plan and indexes
When encountering discrepancies in SQL query results, the immediate action should be to examine the query execution plan and indexes. This helps in identifying any performance bottlenecks, such as missing or inefficient indexes, which may cause unexpected results. Analyzing the query execution plan provides insights into how the database engine processes the query, aiding in optimization efforts.
The SQL function "ERROR_MESSAGE()" returns the ____________ error message text.
- Last occurred
- First occurred
- Most recent
- Least recent
The correct option is "First occurred." The ERROR_MESSAGE() function in SQL returns the first error message text that was encountered during the execution of the last Transact-SQL statement. This can help in identifying the root cause of errors.
In ETL testing, what does the "Transform" phase primarily involve?
- Data cleansing
- Data extraction
- Data manipulation
- Data validation
In ETL (Extract, Transform, Load) testing, the "Transform" phase primarily involves data manipulation, where data is converted or transformed from its source format to the required format for the target system. This phase includes tasks such as data aggregation, filtering, joining, and applying business rules or transformations to ensure that the data meets the desired quality and format for further processing and analysis.
ASP.NET Core's capability to run on different platforms, including Windows, Linux, and macOS, is primarily due to its reliance on the _________ runtime.
- .NET Framework
- .NET Standard
- .NET Core
- .NET Runtime
ASP.NET Core's cross-platform capabilities are mainly enabled by its reliance on the .NET Core runtime. .NET Core is designed to be platform-agnostic, allowing ASP.NET Core applications to run seamlessly on Windows, Linux, and macOS.
While browsing through an ASP.NET Core project, you notice that some HTML files have a .cshtml extension. What are these files called in the context of ASP.NET Core?
- Razor Views
- Web Forms
- HTML Templates
- XML Documents
Files with a .cshtml extension in an ASP.NET Core project are called Razor Views. Razor is a view engine that allows you to embed C# code within HTML to generate dynamic content. These files are responsible for rendering the HTML output for the web application.
You are tasked with setting up an ASP.NET Core environment on a Linux machine. What steps would be essential to ensure the application can be developed, built, and run seamlessly?
- Install .NET Runtime
- Configure IIS
- Set Up Visual Studio
- Configure NGINX
On a Linux machine, the essential step is to install the .NET Runtime to enable ASP.NET Core development. Unlike Windows, IIS is not typically used on Linux, and Visual Studio is primarily a Windows IDE. NGINX is a web server and reverse proxy but isn't required for setting up a development environment.
For creating custom middleware, the delegate needs to accept a _________ and return a Task.
- HttpContext
- HttpRequest
- HttpResponse
- CancellationToken
For creating custom middleware in ASP.NET Core, the delegate used in the middleware pipeline should accept an HttpRequest and return a Task. Middleware operates on the incoming request, and by convention, it often manipulates the request and response. Therefore, it takes an HttpRequest as input. The Task return type allows asynchronous operations to be performed in the middleware.
When might you need to apply Identity migrations in ASP.NET Core?
- When you add or modify user-related data models
- Only during the initial setup
- When you want to improve authentication speed
- When deploying the application
Identity migrations should be applied when you add or modify user-related data models. It's not limited to the initial setup; you should apply migrations whenever there are changes in the Identity-related data structures, such as adding new user properties or changing validation rules.
As a new developer on a team, you're asked to ensure that a custom-built Tag Helper is available across all the Razor views in the project. What steps would you take to achieve this?
- Add the Tag Helper directly to each Razor view where it's needed.
- Register the Tag Helper in _ViewImports.cshtml or the Razor view using @addTagHelper directive.
- Modify the Tag Helper's code to make it available globally.
- Ask other developers to include the Tag Helper in their Razor views.
To make a custom-built Tag Helper available across all Razor views in the project, you should register it in either the _ViewImports.cshtml file or directly in a Razor view using the @addTagHelper directive. This ensures that the Tag Helper is globally accessible and can be used without the need for individual developers to include it in their views.
