You have a list of tasks to complete, some of which depend on others being completed first. You want to determine a sequence to complete the tasks such that all dependencies are honored. What algorithmic approach would be most suitable?
- Greedy Algorithm
- Merge Sort
- Quick Sort
- Topological Sorting
To determine a task sequence while honoring dependencies, 'Topological Sorting' is the most appropriate approach. It is commonly used in project scheduling and task management to create a linear order of tasks in a directed acyclic graph (DAG) while ensuring all dependencies are met.
_______ is a small-sized, high-speed volatile computer memory that provides high-speed data access to the processor and stores frequently used computer programs, applications, and data.
- Cache
- Hard Drive
- RAM
- ROM
'Cache' is a type of high-speed, volatile memory used to store frequently accessed data and instructions, allowing for faster data retrieval by the processor. It acts as a bridge between slower memory (like RAM) and the processor, enhancing system performance.
Which HTTP status code indicates that the server successfully processed the request, but is not returning any content?
- 200 OK
- 204 No Content
- 404 Not Found
- 500 Internal Server Error
The '204 No Content' status code indicates that the server successfully processed the request but is not returning any additional content in the response body. It's often used for operations that have no response data.
You're developing a web application where performance is a critical concern. Which technique would be most suitable for reducing the load times of your web pages?
- Content Delivery Networks (CDNs)
- Object-Oriented Programming
- Static Code Analysis
- Waterfall Model
Content Delivery Networks (CDNs) are crucial for optimizing web page load times. CDNs distribute content to servers closer to the user, reducing latency and speeding up page loading. They cache assets and reduce the load on the origin server, improving performance.
A common tool used to capture and analyze network packets for troubleshooting is called _______.
- Gateway
- LAN Switch
- Packet Sniffer
- Router
A 'Packet Sniffer' is a tool used by network professionals to capture and analyze network packets for troubleshooting, monitoring, and security analysis. It's essential for network diagnostics.
You are tasked with setting up a hybrid cloud for your organization. What would be a primary concern regarding network communication between the on-premises environment and the cloud?
- Data Security
- Energy Efficiency
- Latency
- Scalability
In a hybrid cloud, 'latency' is a primary concern because it refers to the delay in data transmission between on-premises and cloud environments. High latency can affect performance and user experience.
In web development, which protocol is primarily used for secure communication over a computer network?
- FTP
- HTTP
- HTTPS
- SMTP
'HTTPS' stands for Hypertext Transfer Protocol Secure and is used for secure communication over computer networks, especially in web development. It ensures data encryption and secure data transmission.
Which platform-specific language is primarily used for iOS app development?
- C++
- Java
- Python
- Swift
Swift is the primary language for iOS app development. It offers a clean and efficient way to build applications for Apple's ecosystem, making it the preferred choice for iOS developers.
A company is implementing a new ERP system. Midway through the project, they realize that the chosen software doesn't align with some of their core business processes. What should the company consider doing next?
- Abandon the project and start from scratch with a more suitable ERP system.
- Conduct a thorough analysis to identify necessary adjustments and modifications to the chosen ERP system.
- Continue with the current software and modify the business processes to fit.
- Develop custom software to bridge the gap.
In this scenario, the company should conduct a thorough analysis to identify the misalignment between the ERP system and its core business processes. This will help in making informed decisions on necessary adjustments and modifications to ensure a successful implementation.
In NoSQL databases, _______ is a system for storing data in flexible, schema-less documents rather than in traditional tables.
- BSON
- DocumentDB
- JSON
- XML
In NoSQL databases, data is often stored in flexible, schema-less documents, and JSON (JavaScript Object Notation) is a widely used format for this purpose. JSON allows for easy data representation and storage.
