Advanced usage of the Email Class involves ________ to ensure high deliverability rates.
- Email Blacklisting
- Email List Segmentation
- Email Throttling
- SPF and DKIM Configuration
Advanced usage of the Email Class involves configuring SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to authenticate emails. This, in turn, helps improve deliverability rates by establishing trust with email service providers and reducing the likelihood of emails being marked as spam.
The ________ in MVC serves as the application's brain, containing logic and decision-making capabilities.
- Controller
- Model
- Router
- View
In the MVC architecture, the Controller acts as the application's brain, handling user input, processing logic, and making decisions based on the input. It plays a crucial role in controlling the flow of the application.
For secure data transmission, CodeIgniter recommends using ________ to encrypt session data.
- base64_encode
- encrypt
- md5
- ssl_encrypt
CodeIgniter suggests using the encrypt library for secure data transmission, especially when dealing with session data. This library provides a way to encrypt and decrypt sensitive information, adding an extra layer of protection.
In CodeIgniter, which utility is commonly used to backup a database?
- backup class
- dbbackup helper
- dbmanager utility
- dbutil library
The backup class in CodeIgniter is commonly used to perform database backups. It provides a simple and convenient way to create and manage backups of your database.
What is the primary purpose of exception handling in software development?
- To enhance code execution speed
- To handle unforeseen runtime errors
- To improve code readability
- To replace regular error messages
Exception handling in software development serves the purpose of managing unforeseen runtime errors that may occur during program execution. It allows developers to gracefully handle and recover from unexpected issues, preventing the application from crashing abruptly.
How can you enable profiler in CodeIgniter for debugging purposes?
- $this->config->item('enable_profiler', TRUE);
- $this->enable_profiler(TRUE);
- $this->load->library('profiler');
- $this->output->enable_profiler(TRUE);
To enable the profiler in CodeIgniter, you use the $this->output->enable_profiler(TRUE); method. This will display a report at the bottom of your pages, showing benchmark results, queries, and more.
What is the primary HTTP method used to retrieve data in a RESTful API developed with CodeIgniter?
- DELETE
- GET
- POST
- PUT
In a RESTful API, the primary HTTP method used to retrieve data is GET. This method is commonly used for reading resources and does not modify the server's state. In CodeIgniter, you would design your API endpoints to respond to GET requests for data retrieval.
When refactoring a CodeIgniter application for better performance, the first step is to ensure existing unit tests ________.
- Cover all possible edge cases
- Execute successfully without failures
- Include extensive documentation
- Update to the latest CodeIgniter version
The first step in refactoring for better performance is to ensure that existing unit tests execute successfully without failures. This helps ensure that the changes made do not introduce new issues and that the application remains stable.
How does CodeIgniter's session management differ when using database versus file-based storage?
- Database storage allows for more complex session data structures.
- File-based storage is faster and more efficient for session handling.
- File-based storage is recommended for small-scale applications.
- Sessions are more secure when stored in a database due to encryption and server-side validation.
CodeIgniter's session management provides enhanced security when stored in a database by employing encryption and server-side validation. This ensures that sensitive information is better protected. However, developers should be mindful of the performance implications and choose the storage method based on the application's needs.
A mobile app uses OAuth for authentication. The app should primarily use the ________ grant type to ensure security and efficiency.
- Authorization
- Password
- Client Credentials
- Implicit
The correct option is "Client Credentials." This grant type is suitable for confidential clients, such as the mobile app in this scenario, to obtain an access token without the user's involvement. It enhances security and efficiency by authenticating the client itself.
Using ___________ can effectively prevent SQL injection by separating SQL code from user input.
- Data Encryption
- Dynamic SQL
- Parameterized Statements
- Stored Procedures
SQL injection attacks can be prevented by using parameterized statements. These statements ensure that user input is treated as data and not executable code, effectively separating SQL code from user input and preventing malicious injection.
To analyze recurring errors in a CodeIgniter application, the developer should primarily check the ________.
- Apache Server Logs
- Application Logs
- CodeIgniter Profiler
- Database Queries
Checking the application logs in CodeIgniter is a crucial step in analyzing recurring errors. The logs provide detailed information about errors, warnings, and other important events, helping developers identify and fix issues efficiently.
