Which method allows you to update identity-related configurations at runtime rather than during startup?
- IOptionsSnapshot
- IConfiguration
- IOptionsMonitor
- IOptions
To update identity-related configurations at runtime, you should use IOptionsMonitor. This allows for dynamic configuration changes without requiring a server restart, making it suitable for scenarios where runtime updates are essential.
What is the purpose of the asp-for attribute in a Razor form input field?
- It specifies the input field's ID.
- It associates the input field with a model property.
- It sets the input field's value.
- It defines the input field's validation rules.
The purpose of the asp-for attribute in a Razor form input field is to associate the input field with a model property. It creates a binding between the input field and the model property, allowing automatic data binding when the form is submitted. This attribute is essential for model binding in ASP.NET Core, ensuring that form data is correctly mapped to model properties.
In a team discussion, someone suggests using ASP.NET Core Identity. What is a common reason for integrating this into a web application?
- Centralized User Management
- Color Scheme Customization
- Serverless Architecture
- Advanced Data Analytics
A common reason for integrating ASP.NET Core Identity into a web application is centralized user management. It allows the application to have a unified system for managing user accounts, roles, and permissions. This simplifies user authentication, authorization, and user data management, making it easier for teams to maintain and secure the application.
In terms of security, what does ASP.NET Core use to protect against cross-site request forgery (CSRF) attacks?
- Session cookies
- Antiforgery tokens
- Basic authentication
- SSL certificates
ASP.NET Core uses antiforgery tokens to protect against cross-site request forgery (CSRF) attacks. These tokens are generated and validated to ensure that a request originates from a trusted source. Session cookies, basic authentication, and SSL certificates address other security concerns but are not specific safeguards against CSRF attacks.
The ________ folder in an ASP.NET Core MVC project typically contains the shared Razor views like layout and error pages.
- Views
- Shared
- Layouts
- Pages
The "Shared" folder in an ASP.NET Core MVC project typically contains the shared Razor views like layout and error pages. These views can be reused across multiple pages, providing a consistent look and feel to the application.
If a user is not authorized to access a specific action, what default HTTP status code does ASP.NET Core return?
- 200 OK
- 403 Forbidden
- 401 Unauthorized
- 404 Not Found
When a user is not authorized to access a specific action, ASP.NET Core returns a default HTTP status code of 401 Unauthorized. This status code indicates that the request lacks proper authentication credentials or the provided credentials are invalid for the requested resource. It's a fundamental part of the authentication and authorization process in web applications.
For a high-availability deployment of an ASP.NET Core application, which strategy involves deploying the application in such a way that there are multiple instances running simultaneously, typically in different geographical regions?
- Failover Clustering
- Load Balancing
- Georeplication
- Active-Passive Deployment
Georeplication is a strategy that ensures high availability by deploying application instances in different geographical regions. This approach minimizes downtime in case of regional outages or disasters, providing a robust and fault-tolerant architecture.
For API versioning in routing, what is the recommended approach in ASP.NET Core?
- Use query parameters for versioning
- Include version in the request headers
- Embed version in the route URL
- Use custom HTTP headers for versioning
The recommended approach for API versioning in ASP.NET Core is to embed the API version in the route URL. This approach is commonly referred to as "URI versioning" and provides clear versioning information within the request URL, making it easy for developers and clients to understand and use different API versions.
ASP.NET Core's approach to preventing Cross-Site Request Forgery attacks involves using a token named _________.
- Anti-CSRF
- XSRF
- CSRF
- Request-Token
ASP.NET Core's approach to preventing Cross-Site Request Forgery (CSRF) attacks involves using a token named CSRF (Cross-Site Request Forgery). This token is generated for each user session and is included in requests to ensure that the request originated from the same site, thereby preventing malicious actions from other domains. It's an essential security measure in web applications.
ASP.NET Core's configuration system provides a way to access configuration values using a key/value API, a system that can be configured using multiple _________ sources.
- JSON
- Provider
- XML
- YAML
ASP.NET Core's configuration system allows you to access configuration values using a key/value API. This system can be configured using multiple configuration sources (e.g., JSON, XML, environment variables, command-line arguments) to provide flexibility in managing application settings.
