When faced with a slow-running query, a CodeIgniter developer can utilize the ________ utility to diagnose and optimize performance.
- Caching Class
- Encryption Class
- Profiler Class
- Query Builder Class
The Profiler Class in CodeIgniter is used to benchmark and profile your application. When dealing with a slow-running query, a developer can enable the profiler to get detailed information about the query execution, helping diagnose and optimize performance issues.
Which of the following is a common practice to secure file uploads?
- Allowing any file type without restrictions
- Limiting the file types that can be uploaded
- Running file uploads with elevated server privileges
- Storing uploaded files in a public directory
A common practice to secure file uploads is to limit the types of files that can be uploaded. This prevents the upload of potentially harmful file types and adds an additional layer of security. Proper validation and server-side checks should be implemented to enforce this restriction.
To manually complete a transaction in CodeIgniter, the method ________ is used.
- commit()
- completeTransaction()
- endTransaction()
- finishTransaction()
In CodeIgniter, the commit() method is used to manually complete a transaction. This function is called when you want to make the changes permanent after a series of database actions.
OAuth tokens are used to:
- Authorize access to protected resources
- Define database tables
- Store session data
- Validate HTML forms
OAuth tokens are used to authorize access to protected resources. These tokens act as proof of authentication and are required for accessing the user's data or performing specific actions on their behalf.
To improve code readability and reusability, a developer decides to move frequently used HTML structures to a Helper. This process is known as ________.
- code refactoring
- helperization
- templating
- view abstraction
The process of moving frequently used HTML structures to a Helper in CodeIgniter is known as helperization. This enhances code readability and promotes reusability by encapsulating common HTML patterns.
How does CodeIgniter's unit testing class help in improving the quality of the code?
- It automatically fixes common coding errors.
- It ensures proper syntax throughout the codebase.
- It facilitates the creation of automated tests for various parts of the application.
- It optimizes the code for better performance.
CodeIgniter's unit testing class allows developers to create automated tests, ensuring that different parts of the application work as intended. This helps catch bugs early in the development process, improving code quality. Automated tests also make it easier to refactor code without introducing new issues. This process contributes to the overall stability and reliability of the application.
________ should be used in CodeIgniter to securely handle errors containing sensitive information.
- die()
- exit()
- log_message()
- show_error()
In CodeIgniter, the show_error() function should be used to securely handle errors containing sensitive information. It presents a user-friendly error message.
To view detailed benchmarking data in CodeIgniter, the ________ method must be enabled in the controller.
- _output()
- benchmark()
- display()
- render()
In CodeIgniter, the benchmark() method is used to view detailed benchmarking data. This function is commonly used to measure the time taken by specific parts of your code for performance analysis.
In CodeIgniter, what is the recommended approach to secure JSON and XML API endpoints?
- Applying API keys and securing with a token-based system
- Enabling CSRF protection and validating inputs
- Implementing OAuth for API authentication
- Using SSL/TLS for secure data transmission
The recommended approach in CodeIgniter to secure JSON and XML API endpoints is by applying API keys and implementing a token-based system. This helps in authenticating and authorizing requests, ensuring secure communication between clients and the API endpoints.
In CodeIgniter, API rate limiting is often implemented using ________.
- Limit.php
- Rate.php
- Ratelimiter.php
- Throttling.php
CodeIgniter implements API rate limiting through the 'Limit.php' library, allowing developers to control the number of requests a user can make to the API over a specific period.
A developer is setting up a new CodeIgniter project on a shared hosting. The first step they should take for configuration is to adjust the ________.
- Application Language Configuration
- Database Configuration
- Server Environment Configuration
- URL Routing Configuration
When setting up a CodeIgniter project on shared hosting, adjusting the server environment configuration is crucial. This includes setting the base URL, index page, and other server-related settings in the config.php file to match the hosting environment.
In a recent security breach, an SQL injection attack was used to access sensitive data. The initial investigation should focus on the ________ used in the application.
- Authentication protocols
- Coding languages
- Database queries
- Encryption algorithms
The initial investigation should focus on the database queries used in the application. SQL injection attacks exploit vulnerabilities in the construction of database queries, allowing attackers to manipulate or retrieve sensitive data. Analyzing and securing the database queries is crucial in addressing and preventing such security breaches.
