In Django, what is the purpose of a view function?
- Database Manipulation
- Handling Logic
- Styling Pages
- URL Routing
In Django, a view function is primarily used for handling logic, processing data, interacting with the database, and generating dynamic content to be displayed in response to client requests.
Django's templating engine allows for ___________ to dynamically generate HTML content.
- Filters
- Tags
- Templates
- Variables
Django's templating engine allows developers to use variables to dynamically generate HTML content. These variables can be passed from views to templates, enabling dynamic and data-driven web pages.
FTP stands for File Transfer ___________.
- Platform
- Procedure
- Program
- Protocol
FTP (File Transfer Protocol) is a standard network protocol used for transferring files between a client and a server on a computer network. It specifies how files should be exchanged between systems, making it essential for file sharing and management over networks.
___________ is a methodology that emphasizes continuous delivery and customer collaboration.
- Waterfall
- Agile
- Spiral
- RAD
The correct option is Agile. Agile methodology focuses on iterative development, collaboration between cross-functional teams, and continuous delivery of working software. It prioritizes customer feedback and adapts to changing requirements, promoting flexibility and responsiveness in software development projects. Agile methods like Scrum and Kanban are widely used in various industries for their efficiency and adaptability.
Which tool is commonly used for orchestrating containerized applications across a cluster of machines?
- Ansible
- Docker Swarm
- Jenkins
- Kubernetes
Kubernetes is a popular tool for orchestrating containerized applications across clusters of machines. It automates deployment, scaling, and management of containerized applications, making it a key choice for container orchestration.
The purpose of ___________ testing is to verify the behavior of a component in isolation.
- Integration
- Regression
- System
- Unit
Unit Testing focuses on testing individual components or units of code in isolation from the rest of the software system. This allows developers to verify the correctness of each unit's behavior independently before integrating them into larger modules or systems. Integration testing, on the other hand, checks the interactions between these units once they are combined, while Regression testing ensures that changes in code or updates do not negatively impact existing functionalities. System testing evaluates the entire system's functionality in its complete environment.
What is the main benefit of using virtual machines over physical servers?
- Better hardware utilization
- Enhanced security
- Improved scalability
- Increased energy efficiency
Virtual machines offer better hardware utilization compared to physical servers by allowing multiple virtual environments on a single physical machine, thus optimizing resources and reducing costs.
What are Content Security Policy (CSP) directives and how do they prevent various types of attacks?
- Content Security Policy (CSP) directives are rules defined by web administrators to control which resources can be loaded and executed on a web page, effectively mitigating risks associated with cross-site scripting (XSS), data injection, and other types of attacks.
- Content Security Policy (CSP) directives are rules that control the resources a web page is allowed to load and execute, preventing attacks such as XSS, clickjacking, and data injection.
- Content Security Policy (CSP) directives define the policies for resource loading and execution on a web page, including script sources, style sources, and more, to prevent attacks like XSS, data injection, and clickjacking.
- Content Security Policy (CSP) directives specify which content sources are allowed to be loaded and executed on a web page, thus protecting against malicious scripts, unauthorized data access, and other security threats.
Content Security Policy (CSP) directives play a crucial role in enhancing web security by allowing administrators to define rules for resource loading and execution on a web page. These directives prevent various types of attacks, including cross-site scripting (XSS), clickjacking, and data injection, by controlling which content sources are allowed. By specifying trusted sources and enforcing strict policies, CSP helps create a more secure browsing environment for users.
In a ___________ routing table, the network administrator manually configures the routes.
- Adaptive
- Centralized
- Dynamic
- Static
In a static routing table, routes are manually configured by the network administrator. This means that specific routes are explicitly defined and do not change unless modified by the administrator. Dynamic routing tables, on the other hand, are automatically updated based on network conditions and protocols. Adaptive routing refers to a routing algorithm's ability to change routes dynamically based on network congestion or failures. Centralized routing is a concept related to network architecture rather than routing table configuration.
Which function is used to output data to the console in JavaScript?
- log()
- print()
- console.log()
- display()
The console.log() function is used to output data to the console in JavaScript. Option 3 is the correct syntax for using this function to log data to the console, making it the right choice.
