How does OAuth 2.0 differ from OAuth 1.0 in terms of signature requirements?

  • Both OAuth 2.0 and OAuth 1.0 use the same signature requirements.
  • OAuth 2.0 uses bearer tokens without requiring signatures.
  • OAuth 2.0 uses signatures for token validation, unlike OAuth 1.0.
  • OAuth 2.0 uses two-legged authentication without any signatures.
In OAuth 2.0, the signature mechanism is replaced by the use of bearer tokens for better security and simplicity. OAuth 1.0, on the other hand, required signatures for each request, making it more complex.

For complex schema management, CodeIgniter's ________ utility is essential for keeping database structures in sync.

  • Data Evolution
  • Data Synchronization
  • Database Migration
  • Schema Builder
CodeIgniter provides a Database Migration utility for managing database schemas. It allows developers to version control the database structure and keep it in sync across different environments.

In CodeIgniter, which library is commonly used for implementing pagination?

  • Database
  • Form Validation
  • Pagination
  • Session
The Pagination library in CodeIgniter is commonly used for implementing pagination. It provides built-in functionality to organize and split large datasets into smaller pages, facilitating better navigation.

The process of sorting results in a specific order in CodeIgniter's Query Builder is achieved using the ________ method.

  • arrange()
  • order()
  • order_by()

What design pattern is MVC architecture primarily based on?

  • Composite
  • Observer
  • Singleton
  • Strategy
MVC architecture is primarily based on the Singleton design pattern. This pattern ensures that a class has only one instance and provides a global point of access to that instance. In MVC, the Singleton pattern helps in managing the model, view, and controller instances efficiently.

In a news portal developed with CodeIgniter, a developer needs to implement pagination for the latest news section. The challenge is to optimize load times for thousands of news items. The most efficient approach involves ________.

  • Implementing server-side caching for news items
  • Manually fetching all news items and implementing custom pagination logic
  • Using CodeIgniter's built-in pagination library
  • Utilizing AJAX to load news items dynamically on scroll
Efficient pagination for a large number of items is best achieved using CodeIgniter's built-in pagination library. This library handles the generation of pagination links and the SQL query to fetch only the necessary items, optimizing load times.

When debugging an issue where user input is not properly reflected in the database, an expert should first check the ________ component in the MVC architecture.

  • Controller
  • Database Configuration
  • Model
  • View
The issue of user input not properly reflected in the database is likely related to the Model, as it is responsible for handling data manipulation and interactions with the database.

Enabling ________ in CodeIgniter can reduce the server load and improve response time.

  • CSRF Protection
  • Output Compression
  • Query Caching
  • Session Encryption
Output compression reduces the size of the server response, leading to faster page loading times and reduced bandwidth usage. This is crucial for improving the overall performance of a web application.

Which of the following is a key consideration when integrating social media login into your application?

  • Cross-Site Scripting
  • Data Encryption
  • Session Management
  • User Authentication
Integrating social media login involves authenticating users through platforms like Facebook or Google. Ensuring a secure user authentication process is a key consideration to protect user data and maintain the integrity of your application.

In CodeIgniter, the configuration setting $config['sess_ ________'] determines where session data is stored.

  • driver
  • handler
  • path
  • storage
The correct configuration setting is $config['sess_driver'], which determines the storage driver for session data in CodeIgniter. This setting specifies whether session data should be stored in the database, files, or other storage mechanisms.
